In the next three years, drinking water in the United States may be a bit safer from potentially toxic chemicals that have been detected in the blood of 98% of Americans.

Perfluoroalkyl and polyfluoroalkyl substances or PFAS are a family of thousands of man-made chemicals that do not break down easily in the environment. A number of PFAS have been linked to serious health problems, including cancer, fertility issues, high cholesterol, hormone disruption, liver damage, obesity and thyroid disease.

The US Environmental Protection Agency proposed on Tuesday stringent new limits on levels of six PFAS chemicals in public water systems. Under the proposed rule, public systems that provide water to at least 15 service connections or 25 people will have three years to implement testing procedures, begin notifying the public about PFAS levels, and reduce levels if above the new standard, the EPA said.

Two of the most well-studied and potentially toxic chemicals, PFOA and PFOS, cannot exceed 4 parts per trillion in drinking water, compared with a previous health advisory of 70 parts per trillion, the EPA said.

Another four chemicals — PFNA, PFHxS, PFBS and GenX — will be subject to a hazard index calculation to determine whether the levels of these PFAS pose a potential risk. The calculation is “a tool the EPA uses to address the cumulative risks from all four of those chemicals,” said Melanie Benesh, vice president of government affairs for the Environmental Working Group, a consumer organization that monitors exposure to PFAS and other chemicals.

“The EPA action is a really important and historic step forward,” Benesh said. “While the proposed regulations only address a few PFAS, they are important marker chemicals. I think requiring water systems to test and treat for these six will actually do a lot to address other PFAS that are in the water as well.”

For people who are concerned about PFAS exposure, three years or so is a long time. What can consumers do now to limit the levels of PFAS in their drinking water?

First, look up levels of PFAS in your local public water system, suggested David Andrews, a senior scientist at the Environmental Working Group. The advocacy nonprofit has created a national tap water database searchable by zip code that lists PFAS and other concerning chemicals, as well as a national map that illustrates where PFAS has been detected in the US.

However, not all water utilities currently test for pollutants, and many rural residents rely on wells for water. Anyone who wants to personally test their water can purchase a test online or from a certified lab, Andrews said.

“The most important thing is to ensure the testing method can detect down to at least four parts per trillion or lower of PFAS,” he said. “There are a large number of labs across the country certified to test to that level, so there are a lot of options available.”

If levels are concerning, consumers can purchase a water filter for their tap. NSF, formerly the National Sanitation Foundation, has a list of recommended filters.

“The water filters that are most effective for PFAS are reverse osmosis filters, which are more expensive, about in the $200 range,” Andrews said. Reverse osmosis filters can remove a wide range of contaminants, including dissolved solids, by forcing water through various filters.

“Granular activated carbon filters are more common and less expensive but not quite as effective or consistent for PFAS,” he said, “although they too can remove a large number of other contaminants.”

Reverse osmosis systems use both carbon-based filters and reverse osmosis membranes, Andrews explained. Water passes through the carbon filter before entering the membrane.

“The important part is that you have to keep changing those filters,” he said. “If you don’t change that filter, and it becomes saturated, the levels of PFAS in the filtered water can actually be above the levels in the tap water.”

Carbon filters are typically replaced every six months, “while the reverse osmosis filter is replaced on a five-year time frame,” he added. “The cost is relatively comparable over their lifetime.”

Another positive: Many of the filters that work for PFAS also filter other contaminants in water, Andrews said.

Drinking water is not the only way PFAS enters the bloodstream. Thousands of varieties of PFAS are used in many of the products we purchase, including nonstick cookware, infection-resistant surgical gowns and drapes, mobile phones, semiconductors, commercial aircraft, and low-emissions vehicles.

The chemicals are also used to make carpeting, clothing, furniture, and food packaging resistant to stains, water and grease damage. Once treated, the report said, textiles emit PFAS over the course of their lifetimes, escaping into the air and groundwater in homes and communities.

Made from a chain of linked carbon and fluorine atoms that do not readily degrade in the environment, PFAS are known as “forever chemicals.” Due to their long half life in the human body, it can take some PFAS years to completely leave the body, according to a 2022 report by the prestigious National Academies of Sciences, Engineering, and Medicine.

“Some of these chemicals have half-lives in the range of five years,” National Academies committee member Jane Hoppin, an environmental epidemiologist and director of the Center for Human Health and the Environment at North Carolina State University in Raleigh, told CNN previously.

“Let’s say you have 10 nanograms of PFAS in your body right now. Even with no additional exposure, five years from now you would still have 5 nanograms.

“Five years later, you would have 2.5 and then five years after that, you’d have one 1.25 nanograms,” she continued. “It would be about 25 years before all the PFAS leave your body.”

The 2022 National Academies report set “nanogram” levels of concern and encouraged clinicians to conduct blood tests on patients who are worried about exposure or who are at high risk. (A nanogram is equivalent to one-billionth of a gram.)

People in “vulnerable life stages” — such as during fetal development in pregnancy, early childhood and old age — are at high risk, the report said. So are firefighters, workers in fluorochemical manufacturing plants, and those who live near commercial airports, military bases, landfills, incinerators, wastewater treatment plants and farms where contaminated sewage sludge is used.

The PFAS-REACH (Research, Education, and Action for Community Health) project, funded by the National Institute of Environmental Health Sciences, gives the following advice on how to avoid PFAS at home and in products:

  • Stay away from stain-resistant carpets and upholstery, and don’t use waterproofing sprays.
  • Look for the ingredient polytetrafluoroethylene, or PTFE, or other “fluoro” ingredients on product labels.
  • Avoid nonstick cookware. Instead use cast-iron, stainless steel, glass or enamel products.
  • Boycott takeout containers and other food packaging. Instead cook at home and eat more fresh foods.
  • Don’t eat microwave popcorn or greasy foods wrapped in paper.
  • Choose uncoated nylon or silk dental floss or one that is coated in natural wax.

One month later, people living near a toxic train derailment wonder if their lives will ever be back on track | CNN


East Palestine, Ohio
CNN
— 

This had been a quiet little town of about 4,700 people nestled in the rolling hills of Northeast Ohio. A sign posted on State Road 14 welcomes visitors to East Palestine, “the place to be.”

But for the past month, ever since a freight train derailed and caught fire, the town has been bustling with responders and reporters. Residents say they’re grateful for the help, but the attention and uncertainty have begun to strain the town’s hospitality.

Town halls and news conferences have taken over the school auditoriums and municipal buildings and shut down its main street. A clinic opened to address worrisome health questions and symptoms, and government workers have been going door-to-door to survey residents about health impacts.

Gov. Mike DeWine has traveled to East Palestine four times since the derailment and US Environmental Protection Agency Administrator Michael Regan three times, each with entourages of aides and press wranglers. Some business owners near the downtown area are so tired of answering questions, they posted signs asking reporters to stay out.

The streets are busy with utility trucks for environmental clean-up companies TetraTech, Arcadis and AEComm. Plastic hoses snake into Leslie Run and Sulphur Run, two creeks that run through town that were contaminated by the accident. Large pieces of equipment that look like showerheads churn and bubble the water in these streams, hoping to speed the breakdown of chemicals in them.

Still, the floral, fruity odor of the chemical butyl acrylate still wafts up from the streams.

Many residents say they are angry.

Donna Reidy, 62, lives about a mile and a half away from the site in a white house on a hill that overlooks Leslie Run, one of the area waterways contaminated by the spill. On Thursday, she answered questions for a government health study that’s being conducted by the Agency for Toxic Substances and Disease Registry, a division of the US Centers for Disease Control and Prevention.

Reidy said that neither she or her husband – who has lung problems and requires supplemental oxygen – experienced any new or worsening physical symptoms since the derailment. However, her daughter, who also lives in East Palestine, had, she told investigators.

Reidy said her daughter had to gone to the hospital after vomiting and developing a rash. Donna said the stress of trying to protect her husband and worry for her daughter had worsened some anxiety she already struggled with, and she’s afraid of health problems that could arise later on.

“I’ve already had cancer, I don’t want to get it again,” she told Dr. Dallas Shi, an officer in the CDC’s Epidemic Intelligence Service, as they stood in the front yard outside her home.

For the study, called an assessment of chemical exposure, or ACE, Shi is working with a mapping specialist Ian Dunn, a geospatial health scientist and CDC contractor, to interview residents in some of the areas believed to be most impacted by the contamination.

After Reidy answered pages of required questions, Shi and Dunn ask her if there was anything else she wanted them to know.

“Yeah,” she said. “This stuff sucks.”

“We got roots here,” she told them. Five generations of her family lived in East Palestine. Her husband’s father saved money during World War II and sent it home to his wife so they could buy the home they live in today. Her children and grandchildren have gone to the local schools.

“They just ruined everything,” Reidy says, speaking of Norfolk Southern.

“My kids are moving, my grandkids are moving away. They just ruined everything,” she said as she started to cry.

“I’m so sorry,” Shi said, “Can I give you a hug?”

Shi, who was dressed in her dark blue public health service uniform and black work boots, put her arms around Reidy. “I can’t imagine,” she said.

“I’m so mad at them because they’re so cheap and all they cared about was money for themselves,” Reidy went on, speaking through tears. “They should have huge fines against them.”

Then Reidy apologized for getting upset.

On Thursday night, some area residents came to the local high school auditorium for a town hall meeting – their first chance to confront Norfolk Southern since the spill – and expressed similar anger and frustration.

The company was ordered to appear at the town hall by the EPA after declining to participate in earlier events.

“One thing I would like to say … is that we are sorry. We’re very sorry. We feel horrible about it,” said Darrell Wilson, who was representing the company.

The room erupted with shouts of “Buy us out!”

“Do the right thing,” one man shouted. “Tell Alan to buy us out,” referring to Norfolk Southern CEO Alan Shaw.

Several people said they believed staying in their homes was making them ill, but they couldn’t afford to go anywhere else. They want the railroad to buy their homes, which they feel have lost value since the spill.

“Get us out!” some yelled.

“We are going to do the right thing,” Wilson said, responding to the shouts.

Wilson said the company had leased office space in town and “and we signed a long lease. So we’re gonna be here for a long time,” he said..

But when asked whether there had been talk of the company relocating residents, he said there had not.

Some said they had experienced health problems since returning to their homes after the derailment. Others said they had lost their jobs or stopped going to work at jobs they felt were too close to the site. They are worried about their children or grandchildren potentially being exposed to toxins and having health problems down the road.

Some people say they continue to experience symptoms such as headaches, vomiting, dizziness and persistent coughs, and they feel puzzled by ongoing tests of the town’s air and water that have not detected chemicals at levels that are known to pose health risks.

“Why are people getting sick if there are no toxins?” East Palestine resident Jamie Cozza asked the panel answering questions at Thursday’s town hall.

“We do have a team here that is trying to collect health information so that we have a better understanding of the potential exposures and health effects,” said Capt. Jill Shugart, who is an associate director of emergency management at CDC’s Agency for Toxic Substances and Disease Registry, or ATSDR.

The agency is conducting a total of three Assessment of Chemical Exposure, or ACE, investigations – one for Ohio residents, one for people in Pennsylvania, and another for first responders to the accident scene.

Shugart said it would take about three weeks to collect enough information to get an understanding of the full picture, then the agency has to work with Pennsylvania and Ohio to present their findings to residents.

Data from some surveys are starting to come available. On Friday, the Ohio Department of Health released preliminary data from its ACE survey, and out of 168 completed, 74% of people said they experienced headaches, 64% reported anxiety, 61% reported coughing, 58% listed fatigue, and 52% said they had irritation, pain or burning of their skin. The health department is still collecting surveys through its health assessment clinic, which will be open again next week.

Many at the town hall said they felt that the evacuation order had been lifted too soon – less than a week after the derailment – and may have put them in harm’s way, before any potential dangers were fully assessed.

On Thursday, the EPA capitulated to demands from residents and said it would require Norfolk Southern to test for dioxins, cancer-causing chemicals that form during combustion. The EPA had previously declined to require testing for dioxins, saying that these chemicals are already present in the environment, so it’s hard to interpret what their levels mean. The EPA said it would require the railroad company to study background levels of dioxins in comparable areas in order to give some context to the test results.

Authorities have focused much of their concern on a 2-mile radius around the spill, but residents that live farther away, including some farmers in nearby Pennsylvania, say they’ve been impacted, too.

Dave Anderson raises grass fed beef 4 miles downwind of East Palestine, in nearby Darlington Township, Pennsylvania. After the derailment, fire and controlled burn of toxic chemicals, the thick black smoke drifted over his Echo Valley Farm.

“As far as the smoke, you could probably see 100 yards,” Anderson told CNN’s Miguel Marquez.

Anderson said his eyes, throat and mouth burned.

The cloud from the spill settled on his pastures and ponds. Anderson said now he’s not sure whether the grassfed cattle he’s raised for years are safe for human consumption.

So far, there’s been no testing of his water, soil or air on his farm.

Pennsylvania’s Department of Environment Protection, or DEP, just visited Anderson’s farm for the first time this week, nearly four weeks after the event.

In a written statement provided to CNN, the Pennsylvania Department of Agriculture said it launched a hotline encouraging those impacted to reach out if they have concerns about livestock or crops.

Also this week, Pennsylvania opened a community resource center in Darlington to help people who want to get their soil or wells tested. The center is also conducting medical exams for residents with health concerns. Adam Ortiz, regional administrator for EPA’s region 3 office, which includes Pennsylvania, said the center has seen about 100 people a day since it opened.

The crash occurred just feet from the Pennsylvania border. The winds typically blow east, toward Pennsylvania. The state is going house to house, testing soil and water in areas closest to the derailment. Anderson said officials are still trying to figure out if they should extend that testing to other areas.

Samuel Wenger and his wife Joyce had their fourth child, Jackson Hayes, a week ago. Wenger said the state’s response has been too slow and lacking in information to know whether Darlington is still a safe place to raise a family.

They only recently were able to get their well tested, and they were told it would take another three weeks to get the results of that testing. They said it was agonizing to bring their newborn son back to their house when they don’t have answers about contamination.

“I feel like I possibly regret the decision every day but here we live paycheck to paycheck, we live within our means, and we don’t have the financial luxury to pack up and move,” Samuel said. “It’s scary.”

High levels of chemicals could pose long-term risks at Ohio train derailment site, researchers say | CNN



CNN
— 

An analysis of data from the US Environmental Protection Agency’s measurements of pollutants released from the Norfolk Southern train derailment in East Palestine, Ohio, suggests that nine of the dozens of chemicals that the EPA has been monitoring are higher than would normally be found in the area, according to a group of scientists from Texas A&M and Carnegie Mellon University.

If the levels of some of these chemicals remain high, it could be a problem for residents’ health in the long term, the scientists say. Temperature changes or high winds might stir up the chemicals and release them into the atmosphere.

The highest levels found in East Palestine were of a chemical called acrolein, the analysis says.

Acrolein is used to control plants, algae, rodents and microorganisms. It is a clear liquid at room temperature, and it is toxic. It can cause inflammation and irritation of the skin, respiratory tract and mucous membranes, according to the US Centers for Disease Control and Prevention.

“It’s not elevated to the point where it’s necessarily like an immediate ‘evacuate the building’ health concern,” said Dr. Albert Presto, an associate research professor of mechanical engineering at Carnegie Mellon’s Wilton E. Scott Institute for Energy Innovation, who is working on the university’s chemical monitoring effort in East Palestine. “But, you know, we don’t know necessarily what the long-term risk is or how long that concentration that causes that risk will persist.”

Much of what scientists know about chemical exposure comes from people’s contact with chemicals at work, Preston said, which generally means exposure for about eight hours a day. People now living in East Palestine are in constant contact with the chemicals, he said, and the impact of that kind of exposure on the human body is not fully understood.

The EPA and local government officials have repeatedly said that their tests show the air quality in the area is safe and that the chemicals should dissipate. As of Sunday, officials have tested air in 578 homes, and they say chemical pollution levels have not exceeded residential air quality standards.

EPA’s air monitoring data shows that levels of monitored chemicals “are below levels of concern for adverse health impacts from short-term exposures,” an agency spokesperson told CNN on Monday. “The long-term risks referenced by this analysis assume a lifetime of exposure, which is constant exposure over approximately 70 years. EPA does not anticipate levels of these chemicals will stay high for anywhere near that. We are committed to staying in East Palestine and will continue to monitor the air inside and outside of homes to ensure that these levels remain safe over time.”

However, residents have reported rashes and trouble breathing, sometimes even in their own homes, Presto said.

“When someone says to them then, ‘everything is fine everywhere,’ if I were that person, I wouldn’t believe that statement,” he said.

So who’s right? The scientists say it’s not a black-and-white issue.

“I think it’s important for the public to understand that all sides are right. No one’s lying to them,” said Dr. Ivan Rusyn, director of the Texas A&M University Superfund Research Center and part of the team that did the analysis. “It’s just that every time you’re sharing information, whether it’s Administrator of EPA Michael Regan or Governor [Mike] DeWine or someone from Ohio EPA, when they say certain things are ‘safe,’ they really need to explain what they mean.”

Rusyn says the EPA and local officials need to do a better job of communicating with the public about the risk to residents when they are exposed to chemicals released in the crash.

Communication struggles have been a consistent pattern over the years and over numerous environmental disasters, he said. Officials will often do a good job of collecting and releasing data but then fail to give the proper context that the public will understand.

“That’s what I would like to encourage all parties to do rather than to point fingers,” Rusyn said. “The general public has to trust authorities. Cleanup is continuing. They are doing monitoring. We just need to do a better job communicating the results.”

Government communication about residents’ real level of risk has been a significant source of frustration in East Palestine, Presto said.

“People are furious. They feel like they’re getting this black-and-white answer – things are safe or not safe – when it’s not a black-and-white sort of situation,” Presto said.

The EPA says it will continue to monitor the air quality in the area and in residents’ homes. It is also setting up a community center so residents and business owners can ask questions about agency activity there.

The agency said it is collecting outdoor air samples for contaminants of concern, including vinyl chloride, a hard plastic resin used to make plastic products like pipes or packaging material that can be a cancer concern; n-butyl acrylate a clear liquid used to make resins and paint products that can cause eye, throat, nose and lung irritation or damage as well as a skin allergy; and ethylhexyl acrylate, another colorless liquid used to make paints, plastics and adhesives that can cause skin and eye irritation.

The EPA also collected field measurements for hydrogen sulfide, benzene, hydrogen cyanide, hydrogen chloride, phosgene and particulate matter.

Scientists from Texas A&M and Carnegie Mellon are monitoring the chemicals in the area using a mobile lab that they’ve used for the past decade to measure air pollution in real time in cities across the country. They expect to release data from their own tests in East Palestine on Tuesday.

The mobile lab has extremely sensitive equipment that can measure pollution in the parts per trillion. Scientists would then be able to plot them on a graph to show, in real time, where the concentrations of chemicals may be and at what level, Presto said.

Mobile lab workers will try to determine whether there are chemicals in the air that the EPA isn’t monitoring. They are also looking at pollution levels in places where the agency did not set up monitoring stations.

“The situation has to be monitored, and the EPA should continue measurements, and they should also communicate to the general public as to what they’re seeing and put this into context of risk, rather than use the numbers and expect people to figure it out for themselves,” Rusyn said.

Saving water can help us deal with the climate crisis. Here’s how to reduce your use | CNN

Editor’s Note: Sign up for CNN’s Life, But Greener newsletter. Our limited newsletter series guides you on how to minimize your personal role in the climate crisis — and reduce your eco-anxiety.



CNN
— 

The reliability of our faucets providing water every time we turn them on can make water seem like a magical, never-ending resource.

But abusing the availability of this finite resource can contribute to water scarcity and harm our capacity to deal with the impact of the climate crisis.

“Four billion people today already live in places that are affected by water scarcity at least part of the year,” said Rick Hogeboom, executive director of the Water Footprint Network, an international knowledge center based in the Netherlands. “Climate change will have a worsening influence on the demand-supply balance,” he said.

“If all people were to conserve water in some way, that would help ease some of the immediate impacts seen from the climate crisis,” said Shanika Whitehurst, associate director of sustainability for Consumer Reports’ research and testing. Consumer Reports is a nonprofit that helps consumers evaluate goods and services.

“Unfortunately, there has been a great toll taken on our surface and groundwater sources, so conservation efforts would more than likely have to be employed long term for there to be a more substantial effect.”

Yes, businesses and governments should play a part in water conservation by, respectively, producing goods “water efficiently” and allocating water in a sustainable, equitable way, Hogeboom said.

But “addressing the multifaceted water crises is a shared responsibility. No one actor can solve it, nor is there a silver bullet,” he added. “We need all actors to play their part.”

Contrary to what you might think, the water used directly in and around the home makes up a minor portion of the total water footprint of a consumer, Hogeboom said.

“The bulk — typically at least 95% — is indirect water use, water use that is hidden in the products we buy, the clothes we wear and the food we eat,” Hogeboom said. “Cotton, for instance, is a very thirsty crop.”

Of the 300-plus gallons of water the average American family uses every day at home, however, roughly 70% of this use occurs indoors, according to the US Environmental Protection Agency — making the home another important place to start cutting your use.

Here are some ways to reduce your water footprint as you move from room to room and outdoors.

Since the kitchen involves dishwashing, cooking and one of the biggest water guzzlers — your diet — it’s a good place to start.

An old kitchen faucet can release 1 to 3 gallons of water per minute when running at full blast, according to Consumer Reports. Instead of rinsing dishes before putting them in the dishwasher, scrape food into your trash or compost bin. Make sure your dishwasher is fully loaded so you only do as many wash cycles as necessary and make the most use of the water.

With some activities you can save water by not only using less but also upgrading the appliances that deliver the water. Dishwashers certified by Energy Star, the government-backed symbol for energy efficiency, are about 15% more water-efficient than standard models, according to Consumer Reports.

If you do wash dishes by hand, plug up the sink or use a wash basin so you can use a limited amount of water instead of letting the tap run.

If you plan on eating frozen foods, thaw them in the fridge overnight instead of running water over them. For drinking, keep a pitcher of water in the fridge instead of running the faucet until the water’s cool — and if you need to do that to get hot water, collect the cold water and use it to water plants.

Cook foods in as little water as possible, which can also retain flavor, according to the University of Toronto Scarborough’s department of physical and environmental sciences.

When it comes to saving water via what you eat, generally animal products are more water-intensive than plant-based alternatives, Hogeboom said.

“Go vegetarian or even better vegan,” he added. “If you insist on meat, replace red meat by pig or chicken, which has a lower water footprint than beef.”

It takes more than 1,800 gallons of water to produce 1 pound of beef, Consumer Reports’ Whitehurst said.

The bathroom is the largest consumer of indoor water, as the toilet alone can use 27% of household water, according to the EPA. You can cut use here by following this adage: “If it’s yellow, let it mellow. If it’s brown, flush it down.”

“Limiting the amount of toilet flushes — as long as it is urine — is not problematic for hygiene,” Whitehurst said. “However, you do have to watch the amount of toilet paper to avoid clogging your pipes. If there is solid waste or feces, then flush the toilet immediately to avoid unsanitary conditions.”

Older toilets use between 3.5 and 7 gallons of water per flush, but WaterSense-labeled toilets use up to 60% less. WaterSense is a partnership program sponsored by the EPA.

“There’s probably more to gain by having dual flush systems so you don’t waste gallons for small flushes,” Hogeboom said.

By turning off the sink tap when you brush your teeth, shave or wash your face, you can save more than 200 gallons of water monthly, according to the EPA.

Cut water use further by limiting showers to five minutes and eliminating baths. Shower with your partner when you can. Save even more water by turning it off when you’re shampooing, shaving or lathering up, Consumer Reports suggests.

Replacing old sink faucets or showerheads with WaterSense models can save hundreds of gallons of water per year.

Laundry rooms account for nearly a fourth of household water use, according to the EPA. Traditional washing machines can use 50 gallons of water or more per load, but newer energy- and water-conserving machines use less than 27 gallons per load.

You can also cut back by doing full loads (but not overstuffing) and choosing the appropriate water level and soil settings. Doing the latter two can help high-efficiency machines use only the water that’s needed. If you have a high-efficiency machine, use HE detergent or measure out regular detergent, which is more sudsy and, if too much is used, can cause the machine to use more water, according to Consumer Reports.

Nationally, outdoor water use accounts for 30% of household use, according to the EPA. This percentage can be much higher in drier parts of the country and in more water-intensive landscapes, particularly in the West.

If you prefer to have a landscape, reduce your outdoor use by planting only plants appropriate for your climate or ones that are low-water and drought-resistant.

“If maintained properly, climate-appropriate landscaping can use less than one-half the water of a traditional landscape,” the EPA says.

The biggest water consumers outside are automatic irrigation systems, according to the EPA. To use only what’s necessary, adjust irrigation controllers at least once per month to account for weather changes. WaterSense irrigation controllers monitor weather and landscape conditions to water plants only when needed.

Long-term exposure to air pollution may raise risk of depression later in life, study says | CNN



CNN
— 

Exposure to air pollution may be tied to the risk of developing depression later in life, a large new study finds.

Scientists are finding more and more evidence that people who live in polluted areas have a higher risk of depression than those who live with cleaner air. But this study published Friday in JAMA Network Open is one of the first to examine the associations between long-term exposure and the risk of depression diagnosed after age 64.

Depression itself is a serious health condition. When it develops in an older adult, it can also contribute to problems with the ability to think clearly, studies show, as well as physical problems and even death.

Previous research has found that a new diagnosis of depression is less common among older adults than in younger populations.

“That’s one of the biggest reason we wanted to conduct this analysis,” said Dr. Xinye Qiu, co-author of the new study, published Friday in JAMA Network Open. Qiu is a postdoctoral research fellow in the Department of Environmental Health at Harvard T.H. Chan School of Public Health. “Surprisingly, we saw a large number of late-onset depression diagnoses in this study.”

The researchers looked at information on more than 8.9 million people who got their health insurance through Medicare and found that more than 1.52 million were diagnosed with depression later in life during the study period of 2005 to 2016. But the number is probably an undercount; studies show that late-in-life depression is often underdiagnosed.

To determine the study participants’ pollution exposure, Qiu and her co-authors looked at where each of the people diagnosed with depression lived and created models to determine the exposure to pollution at each ZIP code, averaged across a year.

The researchers looked at the study participants’ exposure to three kinds of air pollution: fine particulate matter, also known as PM2.5 or particle pollution; nitrogen dioxide; and ozone.

Particle pollution is the mix of solid and liquid droplets floating in the air. It can come in the form of dirt, dust, soot or smoke. Coal- and natural gas-fired power plants create it, as do cars, agriculture, unpaved roads, construction sites and wildfires.

PM2.5 is so tiny – 1/20th of a width of a human hair – that it can travel past your body’s usual defenses.

Instead of being carried out when you exhale, it can get stuck in your lungs or go into your bloodstream. The particles cause irritation and inflammation and may lead to respiratory problems. Exposure can cause cancer, stroke or heart attack; it could also aggravate asthma, and it has long been associated with a higher risk of depression and anxiety.

Nitrogen dioxide pollution is most commonly associated with traffic-related combustion byproducts. Nitrogen oxides are also released from traffic, as well as through the burning of oil, coal and natural gas. Exposure can increase inflammation of the airways, cause coughing or wheezing and reduce lung function.

Ozone pollution is the main ingredient in smog. It comes from cars, power plants and refineries. This particular pollution is best known for exacerbating asthma symptoms, and long-term exposure studies show a higher risk of death from respiratory diseases in people with higher exposures. The American Lung Association calls it one of the “least well-controlled pollutants in the United States,” and it’s one of the most dangerous.

In the new study, the scientists found that people who lived in areas with higher pollution levels long-term had an increased risk of a depression diagnosis. All three of the pollutants studied were associated with a higher risk of late-onset depression, even at lower pollution levels.

“So there’s no real threshold, so it means future societies will want to eliminate this pollution or reduce it as much as possible because it carries a real risk,” Qiu said.

There were greater associations between depression and exposure to particle pollution and nitrogen dioxide among socioeconomically disadvantaged groups. That may in part be because they are simultaneously exposed to social stress and these poor environmental conditions, the study says.

Older adults who had underlying problems with their heart or breathing were also more sensitive to developing late-in-life depression when exposed to nitrogen dioxide pollution, the study found.

The study has some limitations. The majority of the participants were White, and more research would be needed to see whether there would be a difference among diverse populations.

This is also a population-level study, so there is no way to pinpoint exactly why people exposed to these kinds of air pollutions would have a higher risk of depression.

Other studies have found that exposure to air pollution may affect the central nervous system, causing inflammation and damaging the body’s cells.

Some air pollution, studies show, can also cause the body to release harmful substances that can hurt the blood-brain barrier, the network of blood vessels and tissues made up of closely spaced cells that protect the brain, and that may lead to depression and anxiety.

Because aging can impair the immune response, older adults may be particularly vulnerable to the negative effects of air pollution. More research will be needed to fully understand these connections, as the neural basis for depression is not completely understood.

Another possibility may be that people who live in polluted areas develop physical problems that are associated with worsening psychiatric health, the study said.

“Late-life depression should be a geriatric issue that the public and researchers need to be paying more attention to, like on a similar level with Alzheimer’s and other neurological conditions,” Qiu said.

She is particularly concerned about the effects that climate change will have on this phenomenon. Ozone pollution will increase as the world gets warmer, and the study found that ozone pollution had a stronger association to late-onset depression than particle and nitrogen dioxide pollution.

“Because of this concerning effect we are seeing with ozone, it makes more sense for the government to put some regulation on pollution and also climate mitigation, because rising temperatures and ozone pollution are definitely linked to each other,” Qiu said.

After a train derailment, Ohio residents are living the plot of a movie they helped make | CNN



CNN
— 

When Ben Ratner’s family signed up in 2021 to be extras in the movie “White Noise,” they thought it would be a fun distraction from their day-to-day life in blue-collar East Palestine, Ohio.

Ratner, 37, is in a traffic jam scene, sitting in a line of cars trying to evacuate after a freight train collided with a tanker truck, triggering an explosion that fills the air with dangerous toxins. In another scene, his father wears a trench coat and hat while people walk across an overpass to get out of town. Directors told the group they wanted them to look “forlorn and downtrodden” as they escape the environmental disaster.

The 2022 movie was shot around Ohio and is based on a novel by Don DeLillo. The book was published in 1985, shortly after a chemical disaster in Bhopal, India, that killed nearly 4,000 people. The book and film follow the fictional Gladney family – a couple and their four kids – as they flee an “airborne toxic event” and then return home and try to resume their normal lives.

Ratner tried to rewatch the movie a few days ago and found that he couldn’t finish it.

“All of a sudden, it hit too close to home,” he said.

Ratner and his family – his wife, Lindsay, and their kids, Lilly, Izzy, Simon and Brodie – are living the fiction they helped bring to the screen.

Officials ordered them to evacuate their home last week, a day after a Norfolk Southern train carrying 20 cars of hazardous materials slid off the rails and caught fire, threatening to explode. The National Transportation Safety Board is still investigating the cause of the incident.

“The first half of the movie is all almost exactly what’s going on here,” Ratner said Wednesday, four days into their evacuation.

In a way, the movie has provided a point of grim humor about the situation facing the residents of East Palestine – the joke no one wanted to make.

“Everybody’s been talking about that,” Ratner said of his friends and neighbors who are keeping in close touch through the crisis. “I actually made a meme where I superimposed my face on the poster and sent it to my friends.”

In the 2022 film

Scholars who study DeLillo’s work say they are not surprised by the collision of life and art. His work is often described as prescient, said Jesse Kavadlo, an English professor at Maryville University in St. Louis and president of the Don DeLillo Society.

“The terrible spill now is, of course, a coincidence. But it plays in our minds like life imitating art, which was imitating life, and on and on, because, as DeLillo suggests in ‘White Noise’ as well, we have unfortunately become too acquainted with the mediated language and enactment of disaster,” Kavadlo said.

The night of February 3, Ratner was watching his daughter’s basketball game at the local high school when the crash happened. He didn’t hear it over the noise of the game, but when they walked out of the building, he could see the massive blaze. He shot a few seconds of video on his cell phone.

His family returned to their house, which sits less than a mile from the crash site. Throughout the night, he said, they heard sirens but got little information. “We weren’t sure exactly what the danger was.”

While his family slept, he stayed up, nervously watching the fire and the news.

The next morning, activity around the site had picked up. “There was a lot of commotion, helicopters and people hightailing it out of town, and it was it was a little intense,” he said.

His wife and kids headed to stay with his wife’s parents, who live about 2 miles from the crash site. Ratner went to work running the coffee shop he and his wife own, LiB’s Market, in nearby Salem.

By that afternoon, an official alert warned that people needed to move even farther, beyond a 2-mile radius. Roughly half of the town’s 4,800 residents had to evacuate.

A friend offered to let them stay in their pool house. They later moved to another friend’s house next to their café.

School was canceled for the week. They got their dog out of the house, but they had to leave the pet turtle behind.

For now, they’re keeping their distance. But even after they go back, they have to decide whether they’ll stay.

East Palestine is in an economically depressed area, Ratner said, but it had been on a rebound. He and his wife had been considering opening another café there, but now they’re worried that plan is in jeopardy.

“That’s where we’ve been raising our kids, finishing college, buying a business, and that’s been our place,” he said. “In the future, are we going to have to sell the house? Is it worth any money at this point?”

Five of the tankers on the train that overturned last week were carrying liquid vinyl chloride, which is extremely combustible. Last Sunday, they became unstable and threatened to explode. First responders and emergency workers had to vent the tankers, spill the vinyl chloride into a trench, and then burn it off before it turned the train into a bomb. Authorities feared that an explosion could send shrapnel up to a mile away.

But that didn’t happen. The controlled burn worked and the evacuation order for East Palestine residents was officially lifted Wednesday after real-time air and water monitoring did not find any contaminant levels above screening limits.

“All of the readings we’ve been recording in the community have been at normal concentrations, normal backgrounds, which you find in almost any community,” James Justice, a representative of the US Environmental Protection Agency, said at a briefing Wednesday.

Support team members prepared to assess remaining hazards in East Palestine, Ohio, on February 7.

Although authorities have assured the residents that any immediate danger has passed, some residents have yet to return home. Ratner said they’re worried about longer-term risks that environmental officials are only beginning to assess.

Real-time air readings, which use handheld instruments to broadly screen for classes of contaminants like volatile organic compounds, showed that the air quality near the site was within normal limits.

The decision to lift the evacuation order was based on analysis of air monitoring data, according to Charles Rodriguez, community involvement coordinator for the EPA’s Region 5 office.

Up to this point, officials have been looking for large immediate threats: explosions or chemical levels that could make someone acutely ill.

“Under this phase, it’s been the emergency response,” Kurt Kohler of the Ohio EPA’s Office of Emergency Response said Wednesday. “As you see the emergency services go back home, off-site, Ohio EPA is going to remain involved through our other divisions that oversee the long-term cleanup of these kinds of spills.”

The cleanup and monitoring of the site, he said, could take years.

Although the explosion risk is past, Ratner said, people who live in East Palestine want to know about the chemical threats that might linger.

Fish and frogs have died in local streams. People have reported dead chickens and shared photos of dead dogs and foxes on social media. They say they smell chemical odors around town.

When asked at Wednesday’s briefing about exactly what spilled, representatives from Norfolk Southern listed butyl acrylate, vinyl chloride and a small amount of non-hazardous lube oil.

“Butyl acrylate is a lot of what we’re gathering information on,” said Scott Deutsch, a regional manager of hazardous materials at Norfolk Southern.

Butyl acrylate is a clear, colorless liquid with a strong, fruity odor that’s used to make plastics and paint. It’s possible to inhale it, ingest it or absorb it through the skin. It irritates the eyes, skin and lungs and may cause shortness of breath, according to the National Institute of Occupational Safety and Health. Repeated exposure can lead to lung damage.

Vinyl chloride, which is used to make PVC pipes, can cause dizziness, sleepiness and headaches. It has also been linked to an increased risk of cancer in the liver, brain, lungs and blood.

Although butyl acrylate easily mixes with water and will move quickly through the environment, it isn’t especially toxic to humans, said Richard Peltier, an associate professor of environmental health sciences at the University of Massachusetts at Amherst.

“Vinyl chloride, however, has a specific and important risk in that is contains a bunch of chlorine molecules, which can form some really awful combustion byproducts,” Peltier said. “These are often very toxic and often very persistent in the environment.”

Portions of a Norfolk Southern freight train that derailed February 3 were still on fire the next day.

A spokesperson for Norfolk Southern acknowledged but did not respond to CNN’s request for more information on how much of these chemicals spilled into the soil and water.

The Ohio EPA says it’s not sure yet, either.

“Initially, with most environmental spills, it is difficult to determine the exact amount of material that has been released into the air, water, and soil. The assessment phase that will occur after the emergency is over will help to determine that information,” James Lee, media relations manager for the Ohio EPA, wrote in an email to CNN.

Lee said that after his agency has assessed the site, it will work on a remediation plan.

Vinyl chloride is unstable and boils and evaporates at room temperature, giving it a very short lifespan in the environment, said Dana Barr, a professor of environmental health at Emory University’s Rollins School of Public Health.

“If you had a very small amount of vinyl chloride that was present in an area, it would evaporate within minutes to hours at the longest,” she said.

“But the problem they’re facing here is that it’s not just a small amount, and so if they can’t contain what gets into the water or what gets into the soil, they may have this continuous off-gassing of vinyl chloride that has gotten into these areas,” Barr said.

“I probably would be more concerned about the chemicals in the air over the course of the next month.”

State officials said they would continue to monitor the site for exactly that reason. They are also continuing to try to dig and remove contaminated soil.

“Right now, we have a system set up. As the data comes, it is distributed to a network of people to look at both on an immediate-phase – ‘Hey, is there anything really alarming to look at’ – and those smaller numbers that really matter to long-term health,” Kohler said at Wednesday’s briefing.

He said the local health department would test residents’ wells to make sure their drinking water is safe. Officials are also offering to test the air in residents’ homes before they come back.

Norfolk Southern is funding a phone line for residents to speak to a toxicologist with the Center for Toxicology and Environmental Health, an environmental consulting firm.

No one is quite sure whether to trust the help, though, since it’s coming mostly from the company behind the spill. Some residents have already filed a class-action lawsuit against Norfolk Southern.

“We’re definitely signing up for the air testing of the home before we get in there,” Ratner said.

The first trains to pass since the accident started rolling through again midweek, Ratner said. The roar of the trains, a sound he used to tune out, is now jarring.

Even the sounds of loud trucks are “off-putting,” he said.

Don Cheadle, left, and Adam Driver star in

Ratner said it was fun to be part of a disaster movie – a stylized, darkly comedic Netflix streamer starring Adam Driver, Greta Gerwig and Don Cheadle.

In real life, the situation has been gutting.

“Those are great actors, but it was hard to see it as a put-on,” Ratner said.

He shares the sentiments of Lenny Glavan, a local tattoo artist, who wrote a letter to Norfolk Southern CEO Alan Shaw on Tuesday to express the town’s anger and frustration over the accident.

“You just ripped from us our small-town motto ‘A place you want to be,’ ” Glavan wrote.

“It may not be beach-front property, it may not even have the highest paying jobs, or much else to offer, but in my experiences in life, the place I and most people want to be is when you need a helping hand, a shoulder to cry on, a friend to pray with, or a place to call home East Palestine has always been that place to want to be,” he said in his note, which was publicly posted on Facebook.

“With the events in which have occurred, the railroad that gave this small town life has now taken the life, the heartbeat, the unity and that security that families or individuals long for in this wild world away … possibly indefinitely.”

Common kinds of air pollution led to changes in teens’ blood pressure, study says | CNN



CNN
— 

Scientists know that air pollution can make it difficult to breathe and may ultimately cause serious health problems like cancer, but a new study shows that it might also have a negative impact on teens’ blood pressure.

Exposure to higher levels of nitrogen dioxide was associated with lower blood pressure in teens, according to the study, published Wednesday in the journal PLOS One. Exposure to particulate matter 2.5, also known as particle pollution, was associated with higher blood pressure.

The researchers say the impact is “considerable.”

Other studies have found a connection between blood pressure changes and pollution, but much of that work focuses on adults. Some research has also found negative associations with pollution exposure and younger children, but little has focused on teens.

Generally, low blood pressure can cause immediate problems like confusion, tiredness, blurred vision and dizziness. High blood pressure in adolescence can lead to a lifetime of health problems including a higher risk of stroke or heart attack. It’s a leading risk factor for premature death worldwide.

The study did not look at whether the teens had symptoms or health effects from the change in blood pressure.

The scientists saw this association between pollution and blood pressure in data from the Determinants of Adolescent Social Well-Being and Health study, which tracks the health of a large and ethnically diverse group of children in London over time.

The researchers took data from more than 3,200 teens and compared their records to their exposures to pollution based on annual pollution levels where they lived.

Nitrogen dioxide pollution is most commonly associated with traffic-related combustion byproducts. Nitrogen may help plants grow, but it can impair a person’s ability to breathe and may cause damage to the human respiratory tract. In this study, the nitrogen was thought to be coming predominantly from diesel traffic.

The particle pollution in the study is so tiny – 1/20th of a width of a human hair – that it can travel past the body’s usual defenses. Instead of being carried out when a person exhales, it can get stuck in the lungs or go into the bloodstream. The particles cause irritation and inflammation and may lead to a whole host of health problems.

Particle pollution can come from forest fires, wood stoves, power plants and coal fires. It can also come from traffic and construction sites.

In this study, the link between pollution exposure and changes in blood pressure was stronger in girls than in boys. The researchers can’t determine why there is a gender difference, but they found that 30% of the female participants got the least amount of exercise among the group and noted that that can have an effect on blood pressure.

“It is thus imperative that air pollution is improved in London to maximise the health benefits of physical exercise in young people,” the study says.

Although the study also can’t pinpoint why teens’ blood pressure changed with pollution exposure, others have found that exposure to air pollution may affect the central nervous system, causing inflammation and damage to the body’s cells. Additionally, exposure to particle pollution can disrupt a person’s circadian rhythms, which could affect blood pressure. Particle pollution exposure may also reduce the kidneys’ ability to excrete sodium during the day, leading to a higher nighttime blood pressure level, the study says.

When it came to nitrogen dioxide pollution, the researchers had previously done a crossover study that involved the blood pressure of 12 healthy teen participants who were exposed to nitrogen oxide from a domestic gas cooker with lit burners. Their blood pressure fell compared with participants exposed to only room air.

In the new study, the associations between pollution and blood pressure were consistent. Body size, socieoecomonic status and ethnicity didn’t change the results.

However, it looks only at teens in London, and only 8% of them were people of color. Those children were exposed to higher levels of pollution than White children, the study found.

Levels of pollution in London are also well above what World Health Organization guidelines suggest is safe for humans. However, the same could be said for most any area in the world. In 2019, 99% of the world’s population lived in places that did not meet WHO’s recommended air quality levels.

Earlier work has shown that pollution can damage a young person’s health and may put them at a higher risk for chronic diseases like heart problems later in life. Studies in adults found that exposure to air pollution can affect blood pressure even within hours of exposure.

Pollution caused 1 in 6 deaths worldwide in 2019 alone, another study found.

Some experts suggest that one way to reduce a teen’s risk of pollution-related health problems is to invest in portable air cleaners with HEPA filters that are highly effective at reducing indoor air pollution. However, the filters can’t remove all of the problem, and experts say communitywide solutions through public policy are what’s needed.

Dr. Panagis Galiatsatos, an assistant professor in pulmonary and critical care medicine at Johns Hopkins Medicine, said research like this is important to generate a hypothesis about what these pollutants are doing to people. Galiatsatos, a volunteer medical spokesperson with the American Lung Association, was not involved with the new study.

“A lot of these air pollutions tend to cluster in economically disadvantaged neighborhoods, so it’s one of the big reasons we want to always keep a close eye on this, as it disproportionately impacts certain populations more than others,” he said.

Blood pressure is an important marker to track for health because it is a surrogate to understand the more complex processes that might be happening in the body.

“My big takeaway is that these toxins clearly seem to have some physiological impact on the cardiovascular system, and any manipulation should be taken into the context of a concern,” Galiatsatos said.

Study co-author Dr. Seeromanie Harding, a professor of social epidemiology at King’s College London, said she hopes it will lead to more research on the topic.

“Given that more than 1 million under 18s live in [London] neighborhoods where air pollution is higher than the recommended health standards,” she said in a news release, “there is an urgent need for more of these studies to gain an in-depth understanding of the threats and opportunities to young people’s development.”

Climate change is contributing to the rise of superbugs, new UN report says | CNN



CNN
— 

Climate change and antimicrobial resistance are two of the greatest threats to global health, according to a new report from the United Nations Environment Programme.

The report, titled “Bracing for Superbugs,” highlights the role of climate change and other environmental factors contributing to the rise of antimicrobial resistance. It was announced Tuesday at the Sixth Meeting of the Global Leaders Group on Antimicrobial Resistance in Barbados.

Antimicrobial resistance or AMR happens when germs such as bacteria, viruses and fungi develop the ability to defeat the medications designed to kill them.

“The development and spread of AMR means that antimicrobials used to prevent and treat infections in humans, animals and plants might turn ineffective, with modern medicine no longer able to treat even mild infections,” the UN Environment Programme said in a news release.

Roughly 5 million deaths worldwide were associated with antimicrobial resistance in 2019, and the annual toll is expected to increase to 10 million by 2050 if steps aren’t taken to stop the spread of antimicrobial resistance, according to the report.

In the US, there are nearly 3 million antimicrobial-resistant infections each year, and more than 35,000 people die as a result, the US Centers for Disease Control and Prevention says.

Antimicrobials are commonly used in cleaning products, plant pesticides and medications to kill and prevent the spread of germs among people, animals and crops.

Drug resistance can develop naturally, but experts say the overuse of antimicrobials in people, animals and food production has accelerated the process. The microorganisms that survive these chemicals are stronger and more powerful, and they can spread their drug-resistant genes to germs that have never been exposed to antimicrobials.

The focus so far has largely been on excessive antimicrobial use, but experts say there is growing evidence that environmental factors play a significant role in the development, transmission and spread of antimicrobial resistance.

“Climate change, pollution, changes in our weather patterns, more rainfall, more closely packed, dense cities and urban areas – all of this facilitates the spread of antibiotic resistance. And I am certain that this is only going to go up with time unless we take relatively drastic measures to curb this,” said Dr. Scott Roberts, an infectious diseases specialist at Yale School of Medicine, who was not involved with the new UN report.

The climate crisis worsens antimicrobial resistance in several ways. Research has shown that increased temperatures increase both the rate of bacterial growth and the rate of the spread of antibiotic-resistant genes between microorganisms.

“As we get a more extreme climate, especially as it warms, the gradients that drive the evolution of resistance will actually accelerate. So, by curbing temperature rises and reducing the extremity of events, we can actually then fundamentally curb the probability of evolving new resistance,” Dr. David Graham, a professor of ecosystems engineering at Newcastle University and one of the UN report’s authors, said at a news conference ahead of the report’s release.

Experts also say severe flooding as a result of climate change can lead to conditions of overcrowding, poor sanitation and increased pollution, which are known to increase infection rates and antimicrobial resistance as human waste, heavy metals and other pollutants in water create favorable conditions for bugs to develop resistance.

“The same drivers that cause environmental degradation are worsening the antimicrobial resistance problem. The impacts of antimicrobial resistance could destroy our health and food systems,” Inger Andersen, the UN Environment Programme’s executive director, said at the news conference.

Environmental pressures are creating bugs that thrive in the human body, which experts say is unusual for some species.

“There’s one hypothesis from a prominent mycologist who suggests that the reason the body’s temperature is 98.6 is because that is the temperature where fungi can’t grow that well. And so, now we’re seeing Candida auris and some of the other new microbes that have come up that really grow quite well – even at temperatures of 98.6 in the human body. And so I think climate change, really selecting for these organisms to adapt to a warmer climate, is going to increase the odds that there’s infection in humans,” Roberts said.

Such opportunistic infections jeopardize medical advancements like joint replacements, organ transplants and chemotherapy – procedures in which patients have a significant risk of infection and require effective antibiotics.

Drug-resistant infections can make treatment difficult or even impossible. Roberts says that resorting to “last-ditch treatments” is “never a good scenario from the patient level because there are reasons we don’t use them up front,” such as organ toxicity and failure.

“When somebody does present with a drug-resistant bacteria or fungus and we really need to rely on one of these last-line antibiotics, it’s usually a challenge to treat from the outset. And so the patients really don’t do as well as a result,” he said. “In rare circumstances, we run out of options entirely, and in that case, there’s really nothing we can do. Fortunately, those cases remain quite rare, but I am certain that with this growing antibiotic resistance problem, we’ll see these increasing frequency over time.”

Experts say that both climate change and antimicrobial resistance have been worsened by and can be improved by human actions. One critical step is to limit antibiotic overuse and misuse.

“Antibiotics and antifungals do not work on viruses, such as colds and the flu. These drugs save lives. But, anytime they are used, they can lead to side effects and antimicrobial resistance,” the UN report’s authors wrote.

The authors also emphasize that the health of people, animals, plants and the environment are closely linked and interdependent, and they call on governments to identify policies to limit antibiotic use in agriculture and reduce environmental pollution.

Finally, experts say, steps to reduce climate change are steps to limit antimicrobial resistance.

“Whatever we can do on an individual level to kind of reduce the impact of climate change, really, that’s kind of only worsening this problem, as well as pollution and urbanization and in dense, crowded areas. Although I know from the individual level that’s a hard thing to change,” Roberts said.

FDA proposes new levels for lead in baby food, but critics say more action is needed | CNN



CNN
— 

The allowable levels of lead in certain baby and toddler foods should be set at 20 parts per billion or less, according to new draft guidance issued Tuesday by the US Food and Drug Administration.

“For babies and young children who eat the foods covered in today’s draft guidance, the FDA estimates that these action levels could result in as much as a 24-27% reduction in exposure to lead from these foods,” said FDA Commissioner Dr. Robert Califf in a statement.

The

Baby foods covered by the new proposal – which is seeking public comment – include processed baby foods sold in boxes, jars, pouches and tubs for babies and young children younger than 2 years old, the agency said.

While any action on the part of the FDA is welcome, the suggested levels of lead are not low enough to move the needle, said Jane Houlihan, the national director of science and health for Healthy Babies Bright Futures, a coalition of advocates committed to reducing babies’ exposures to neurotoxic chemicals.

“Nearly all baby foods on the market already comply with what they have proposed,” said Houlihan, who authored a 2019 report that found dangerous levels of lead and other heavy metals in 95% of manufactured baby food.

That report triggered a 2021 congressional investigation, which found leading baby food manufacturers knowingly sold products with high levels of toxic metals.

“The FDA hasn’t done enough with these proposed lead limits to protect babies and young children from lead’s harmful effects. There is no known safe level of lead exposure, and children are particularly vulnerable,” Houlihan said.

The director of food policy for Consumers Reports, Brian Ronholm, also expressed concerns. In 2018, Consumer Reports analyzed 50 baby foods and found “concerning” levels of lead and other heavy metals. In fact, “15 of them would pose a risk to a child who ate one serving or less per day,” according to Consumer Reports.

“The FDA should be encouraging industry to work harder to reduce hazardous lead and other heavy metals in baby food given how vulnerable young children are to toxic exposure,” Ronholm said in a statement.

Exposure to toxic heavy metals can be harmful to the developing brain of infants and children. “It’s been linked with problems with learning, cognition, and behavior,” according to the American Academy of Pediatrics.

Lead, arsenic, cadmium and mercury are in the World Health Organization’s top 10 chemicals of concern for infants and children.

As natural elements, they are in the soil in which crops are grown and thus can’t be avoided. Some crop fields and regions, however, contain more toxic levels than others, partly due to the overuse of metal-containing pesticides and ongoing industrial pollution.

The new FDA guidance suggests manufactured baby food custards, fruits, food mixtures — including grain and meat-based blends — puddings, vegetables, yogurts, and single-ingredient meats and vegetables contain no more than 10 parts per billion of lead.

The exception to that limit is for single-ingredient root vegetables, such as carrots and sweet potatoes, which should contain no more than 20 parts per billion, according to the new guidance.

Dry cereals marketed to babies and toddlers should also not contain more than 20 parts per billion of lead, the new FDA guidance said.

However, the FDA didn’t propose any lead limit for cereal puffs and teething biscuits, Houlihan said, even though the products account for “7 of the 10 highest lead levels we’ve found in over 1,000 baby food tests we have assessed.”

The limit set for root vegetables will be helpful, Houlihan added. Because they grow underground, root vegetables can easily absorb heavy metals. For example, sweet potatoes often exceed the 20 parts per billion limit the FDA has proposed, she said.

Prior to this announcement, the FDA had only set limits for heavy metals in one baby food — infant rice cereal, Houlihan said. In 2021, the agency set a limit of 100 parts per billion for arsenic, which has been linked to adverse pregnancy outcomes and neurodevelopmental toxicity.

There is much more that can be done, according to Scott Faber, senior vice president of government affairs for the Environmental Working Group, a nonprofit environmental health organization.

“We can change where we farm and how we farm to reduce toxic metals absorbed by plants,” Faber said. “We also urge baby food manufacturers to conduct continuous testing of heavy metals in all their products and make all testing results publicly available.”

Companies can require suppliers and growers to test the soil and the foods they produce, and choose to purchase from those with the lowest levels of heavy metals, Houlihan added.

“Growers can use soil additives, different growing methods and crop varieties known to reduce lead in their products,” she said.

What can parents do to lessen their child’s exposure to toxic metals? Unfortunately, buying organic or making baby food at home isn’t going to solve the problem, as the produce purchased at the grocery store can also contain high levels of contaminants, experts say.

A 2022 report by Healthy Babies, Bright Futures found lead in 80% of homemade purees or store-bought family foods. Arsenic was found in 72% of family food either purchased or prepared at home.

The best way to lessen your child’s exposure to heavy metals, experts say, is to vary the foods eaten on a daily basis and choose mostly from foods which are likely to have the least contamination. Healthy Babies, Bright Futures created a chart of less to most contaminated foods based on their testing.

Fresh bananas, with heavy metal levels of 1.8 parts per billion, were the least contaminated of foods tested for the report. After bananas, the least contaminated foods were grits, manufactured baby food meats, butternut squash, lamb, apples, pork, eggs, oranges and watermelon, in that order.

Other foods with lower levels of contamination included green beans, peas, cucumbers and soft or pureed home-cooked meats, the report found.

The most heavily contaminated foods eaten by babies were all rice-based, the report said. Rice cakes, rice puffs, crisped rice cereals and brown rice with no cooking water removed were heavily contaminated with inorganic arsenic, the more toxic form of arsenic.

After rice-based foods, the analysis found the highest levels of heavy metals in raisins, non-rice teething crackers, granola bars with raisins and oat-ring cereals. But those were not the only foods of concern: Dried fruit, grape juice, arrowroot teething crackers and sunflower seed butter all contained high amounts of at least one toxic metal, according to the report.

While buying organic cannot reduce the levels of heavy metals in infant food, it can help avoid other toxins such as herbicides and pesticides, Dr. Leonardo Trasande, director of environmental pediatrics at NYU Langone Health told CNN previously.

“There are other benefits to eating organic food, including a reduction in synthetic pesticides that are known to be as bad for babies, if not even more problematic,” Trasande said.

Millions have the same ‘bendy body’ disease as my daughter. Why isn’t the medical profession paying more attention? | CNN



CNN
— 

One day in July 2021, my then 15-year-old daughter Poppy stumbled and fell while walking down some stairs, grazing her knee. It wasn’t a serious wound, but over the weeks it didn’t heal.

Around the same time, her wrists and knees became sore; her ankles started rolling when she walked; her hands began shaking; her headaches and stomach aches became more frequent and intensely painful. She was always exhausted.

Before her health declined, Poppy had enjoyed horse riding and gymnastics, she’d competed in cross country races and been a fearless goalkeeper for the school hockey team.

But within a couple of months, as walking became increasingly difficult, she asked me for a walking stick. We found one that folds up and fits neatly in her school bag.

I took Poppy to doctors who conducted tests, but they couldn’t find out what was wrong with her. Then, in October, a breakthrough.

A podiatrist who was measuring Poppy for insoles to support her aching feet asked if Poppy could bend her thumb to reach her forearm. She could. Could she pull her little finger back to form a 90-degree angle with the back of her hand? She could do that, too.

“Have you heard of Ehlers-Danlos syndrome?” the podiatrist asked me. I hadn’t – so as soon as I got home, I went looking on the internet.

There are 13 types of Ehlers-Danlos syndrome (EDS), according to research and advocacy organization The Ehlers-Danlos Society. Most types are very rare, and can be diagnosed using genetic tests. However, the genes that cause hypermobile EDS (hEDS) – the most common form, accounting for about 90% of cases – are unknown, so diagnosis is based on a checklist of symptoms. The list includes a hypermobility rating, known as the Beighton Score.

Poppy had enough symptoms to qualify for hEDS, and the diagnosis was confirmed by a doctor one year ago, on Christmas Eve. He told us that although we can do our best to alleviate some symptoms, there is no cure.

Poppy reacted to the news better than I did. She had known for some time that something was fundamentally wrong. The diagnosis was upsetting but identifying her illness also gave her a sense of relief. I felt shocked and overwhelmed, and I cried for weeks.

Reading about EDS was like a dreadful slow reveal.

I learned that it’s a genetic disorder that causes the body to make faulty connective tissue, and connective tissue is everywhere – in the tendons, ligaments, skin, heart, digestive system, eyes and gums.

Weak connective tissue leads to hypermobility, which may sound like a good thing, but some people with bendy bodies suffer a mind-boggling array of symptoms, including joint dislocations and subluxations (like a mini dislocation, when the joint partially slips out of place), soft stretchy skin, abnormal scarring, poor wound healing, gastrointestinal disorders, chronic pain and fatigue.

The severity of symptoms varies wildly. Patients with milder cases can lead relatively normal lives, while others become housebound, and some can’t digest food and must be fed through tubes.

What’s more, people with hEDS are prone to other conditions, including POTS (postural orthostatic tachycardia syndrome, which makes you dizzy when you stand up) and MCAS (mast cell activation syndrome, which gives you allergy-type symptoms).

I learned a lot of new acronyms and they all spelled bad news.

I initially thought hEDS was rare, because all forms of EDS are commonly referred to as rare. But within a few weeks, I felt like I was seeing references to hEDS everywhere. Actor, writer and director Lena Dunham; actor and presenter Jameela Jamil; and drag queen Yvie Oddly live with it. I deep dived into EDS Twitter and EDS Instagram, while Poppy found it comforting to watch TikTok videos made by teenagers with the condition.

I discovered multiple patient groups on Facebook, each with tens of thousands of members, which turned out to be great sources of support. I asked questions (what kind of shoes are best for weak ankles? Which knee braces are easiest to pull on and off?) and kind strangers sent helpful advice. At the same time, scrolling through countless personal stories of pain, despair and shattered dreams made me feel terrified about what might lie ahead.

I noticed common themes. Many EDS patients had spent years seeking the correct diagnosis; others felt they’d been neglected and gaslit by doctors.

There was also a lot of talk of zebras.

Linda Bluestein, a Colorado-based physician who specializes in EDS and other hypermobility conditions, and has hEDS herself, explains why.

“I was told in medical school, ‘when you hear hoofbeats think horses, not zebras,’” she says. Many trainee doctors receive the same advice – when a patient presents with symptoms, “look for the common thing.” That’s why EDS patients commonly refer to themselves as zebras – and also use the fabulous collective noun “dazzle.” The name represents rarity and evokes the stripy stretch marks that are a common feature on EDS skin.

But if people with hEDS are medical zebras, why am I encountering so many of them?

Bluestein says that for many years it was thought that one in 5,000 people had Ehlers-Danlos syndrome. But she says the limited research that’s been carried out into the prevalence of hEDS suggests the true number of cases is “much, much higher” than that.

Dr. Linda Bluestein has treated hEDS patients  who have been searching for a diagnosis for decades.

Bluestein points me to a 2019 study carried out in Wales – a country of 3.1 million people. An examination of primary care and hospital records from 1990 to 2017 found that one in 500 people there has either hEDS or joint hypermobility syndrome (a similar condition with a slightly different set of symptoms). She says it’s “a good study” but believes it’s still an underestimate. The Ehlers-Danlos Society says more population studies need to be done to give a more accurate view of its incidence elsewhere.

But despite this possible prevalence, and how debilitating hypermobility disorders can be, the average time to diagnosis from the onset of symptoms is 10 to 12 years, according to The Ehlers-Danlos Society.

Bluestein has firsthand experience of this. Growing up, she wanted to become a ballet dancer and trained six days a week. When puberty hit, she started experiencing joint pain and migraines, and at 16 had her first orthopedic surgery. She realized she wouldn’t succeed in the ballet world and instead pursued her “back-up plan,” to become a doctor. But despite her career choice, Bluestein only received her hEDS diagnosis when she was 47 – more than 30 years later.

“I told my doctor on numerous occasions, ‘there is something wrong with me, I don’t heal well, I get injured more easily than other people’,” she says. “And he just never, never listened.”

Why, for so many patients, does it take so long to get diagnosed?

In 2014 a leading EDS expert, Professor Rodney Grahame, remarked at a conference that “no other disease in the history of modern medicine has been neglected in such a way as Ehlers-Danlos syndrome.”

Far more women than men are diagnosed with EDS, which could help to explain the neglect, because the medical profession has a long history of overlooking health complaints made by women.

A 2009 study, conducted by the European Organisation for Rare Diseases, surveyed 414 families of EDS patients from five countries and found that the average delay to an EDS diagnosis was four years for men – but 16 years for women.

The report states that women with EDS tend to be “diagnosed later because their pain and hypotonia (poor muscle tone) aren’t considered as physical symptoms but rather as psychological symptoms or common complaints.”

“We tend to get dismissed a lot more easily,” says Bluestein. “People jump to the conclusion that we’re histrionic females.”

Anxiety is very common in patients with hypermobility issues, says Bluestein, which can cloud the picture. “When people with anxiety present to a physician, it can suck all the air out of the room, so that the physician almost can’t see anything else.”

This can ramp up the patient’s anxiety further “because people aren’t validating our symptoms, and then we start to doubt ourselves,” she says.

What’s more, medicine is divided into silos which creates the “worst possible model” for EDS patients, says Bluestein.

She explains that undiagnosed patients might consult a neurologist for their migraines, a rheumatologist for joint pain, a cardiologist for palpitations, a gastroenterologist for digestive issues and a urologist for bladder symptoms. Each doctor focuses on the symptoms that fall within their specialty but doesn’t consider the other ailments. “Nowhere along the way does somebody realize that there are certain conditions that could tie all of these things together and explain everything,” says Bluestein.

The 2009 rare diseases study found that during the quest for a diagnosis, 58% of EDS patients consulted more than five doctors, and 20% consulted more than 20.

The consequences of not getting diagnosed for years can be devastating.

Melissa Dickinson, a psychotherapist in Atlanta, Georgia, says she experienced symptoms of a “mystery illness” since childhood. Then in 2013, she “went on honeymoon to Mexico, relatively healthy, and came back disabled and with a dislocated neck.”

While on vacation, Dickinson says she got food poisoning and was prescribed ciprofloxacin, an antibiotic that can pose a serious risk of aortic aneurysm to people with EDS. Instead, she says it triggered significant nerve damage, digestive issues that almost made her go blind because her body wasn’t absorbing nutrients, and put her in a wheelchair.

Dickinson, who finally received her hEDS diagnosis in 2014, says taking the wrong medication “wrecked me from head to toe.” Now that she’s receiving treatment, “I can walk with mobility aids, but most of my body has to have constant support to function.”

Lara Bloom, president and CEO of The Ehlers-Danlos Society, who herself has hEDS, says many patients have “medicalized PTSD.”

“They have had to stop their careers, they’ve had to drop out of school, their relationships have broken down.” The delay inevitably results in worsening symptoms and a declining quality of life, she says. In worst-case scenarios, patients “are dying by suicide, they’re self-harming.”

Sometimes, the failure to diagnose EDS has led to children being taken away from their parents.

In 2010, Americans Rana Tyson and her husband Chad were falsely accused of harming their 4-week-old twin daughters, who had unexplained fractures in their legs.

Along with their older sister, the baby girls were taken by state authorities in Texas and sent to live with relatives. “It was the worst day of my life,” Tyson tells me in a phone call.

Five months later, a geneticist identified the twins as having a connective tissue disorder, and they were subsequently diagnosed with EDS and a vitamin D deficiency. The family was reunited but “12 years later, it still hurts,” says Tyson.

Bloom says some other parents of children with EDS have been wrongly accused of “fabricated or induced illness (FII)” – a rare form of abuse, formerly known as Munchausen’s syndrome by proxy, in which a parent or care giver deliberately causes symptoms or tries to convince doctors that a healthy child is ill.

Ellie Pattison, who has hEDS, has been repeatedly misdiagnosed as having an eating disorder.

Ellie Pattison, a 19-year-old student who lives in County Durham, England, suffers from severe digestive issues linked to hEDS.

Throughout her childhood, Ellie was repeatedly misdiagnosed as having an eating disorder, she says, while her mother Caroline was accused of FII on three separate occasions. Caroline successfully fought to keep her daughter at home, says Ellie, but the ordeal has left the whole family with “an unimaginable amount of trauma.” Ellie says she suffered from PTSD and endured years of horrific nightmares, triggered by living with the fear from a young age that she could be forcibly separated from her family.

This underlines why prompt diagnosis is so important, says Bloom. “Our hope and dream is for people to get diagnosed when their symptoms begin.”

In the case of hEDS, a crucial first step is to find out what causes it.

Cortney Gensemer, a biomedical scientist in the Norris Lab at the Medical University of South Carolina’s department of Regenerative Medicine and Cell Biology, is trying to solve this mystery. She and research mentor Russell Norris, head of the lab, have been studying a gene mutation they believe causes hEDS (the results of the study are currently under peer review).

Like Poppy, Gensemer was diagnosed with hEDS as a teenager. She says the disease affects every aspect of her work. Looking down a microscope is particularly painful at times – her neck is unstable because of her hEDS, and she’s had metal screws put into some of her neck vertebrae to fuse them.

Norris kitted the lab out with special equipment, including motion sensor doors (standard lab doors are very heavy), adjustable chairs and ergonomic pipettes that are gentle on the hands. “If I didn’t have all that stuff, I don’t think I’d be able to do it,” says Gensemer.

To find a hEDS-causing gene, Gensemer says she and Norris sampled DNA from a large family with cases spanning four generations and looked for a mutation that appears only in relatives who have the disease. They identified a “strong candidate gene” and inserted it into mice using gene editing tools.

Gensemer and Norris found that the hEDS mice had significantly more lax tissues, and floppier tails than regular rodents. “You can tie a loose knot into the mutant mouse tail. With a normal mouse tail, you can (only) bend it into a circle,” Gensemer says.

The gene that Gensemer and Norris found won’t account for all hEDS cases, she says. They believe that eventually multiple genes will be identified, and hEDS may be split into different subtypes. This would help to explain why different patients have different symptoms. Crucially, if genetic information sheds light on how the connective tissue is “messed up,” it could lead to effective treatments, says Gensemer.

The Ehlers-Danlos Society is also looking for genes as well as blood markers, working with a team of experts to sequence and analyze the DNA of 1,000 hEDS patients from around the world. And at the UK’s University of Warwick, Ph.D. candidate Sabeeha Malek, another scientist with hEDS, has proposed that EDS might be caused by a fault in the way that collagen binds to cell membranes in connective tissue. If she’s right, she hopes her work will lead to a skin biopsy test that could identify all forms of the disease.

Sabeeha Malek is working to identify biomarkers that could make EDS diagnosis easier.

Progress is being made but on a very small scale. “If you look at any major academic institution, there are multiple labs studying cancer, multiple labs studying heart disease. When you look at a disease that affects one in 500 people, and probably more than that, there should be a lab studying it at every single academic institution,” says Gensemer.

Gensemer hopes that as more discoveries are made and data is accumulated it will “change the way the medical community looks at the disease” – and that it will be taken more seriously.

A year has passed since Poppy’s diagnosis. The initial shock has subsided, and while I’m still grieving the loss of her health, we’ve both learned to accept our new reality and have adjusted to living with EDS.

I’ve assembled a team of supportive doctors and therapists and acquired an arsenal of paraphernalia to fight pain and manage symptoms, including braces and kinesiology tape to hold her joints in place; ice packs, heat pads, tiger balm and arnica gel for sore muscles; and a cupboard full of medications and supplements.

With Poppy often stuck at home, I also got her a giant kitten that she calls Bagel, and he provides the best therapy.

Writing this article has taught me a lot more about EDS: It’s been upsetting to report on the terrible experiences some have suffered, but I’ve been awestruck by the dedication of people, many with the condition themselves, who are working to find solutions.

I don’t know what the future holds for Poppy. Some patients’ symptoms improve with age; others experience an increase in pain and a loss of mobility. I’ve learned there’s a limit to what we can control but there’s a lot we can do, to tackle symptoms and make life easier. And I believe that change is coming.

With a better understanding of the condition and diagnostic tools on the horizon, my biggest hope is that there will be a cure one day – and that it will come in time for Poppy.
