A quarter of Americans live with polluted air, with people of color and those in Western states disproportionately affected, report says | CNN

About 1 in 4 people in the United States – more than 119 million residents – live with air pollution that can hurt their health and shorten their lives, according to a new report from the American Lung Association. People of color are disproportionately affected, as are residents of Western cities.

Since President Richard Nixon signed the Clean Air Act in 1970, emissions of outdoor air pollutants have fallen 78%, according to the US Environmental Protection Agency. But Wednesday’s 2023 State of the Air report, which focuses on ozone and particle pollution, shows that millions put their health on the line every time they step outside.

To capture pollution levels at the county level, researchers analyzed data collected by the EPA’s Air Quality System, a repository of ambient air quality data from more than 10,000 monitors. They characterized the hourly average ozone concentration and the 24-hour average particle pollution concentration for 2019-21 at each monitoring site and factored in year-round pollution information from the EPA.

There were significant improvements in some areas. Generally, 17.6 million fewer people were breathing unhealthy air than in last year’s report, due largely to falling levels of ozone in some regions.

Ozone pollution is the main ingredient in smog. It comes from cars, power plants and refineries. Exposure to ozone can immediately exacerbate asthma symptoms, and people with long-term exposure to higher levels face a significantly higher risk of death from respiratory diseases than those who live with cleaner air.

Around 25% more counties got an A grade in the report for lower levels of ozone pollution. Some of that improvement can be attributed to the Clean Air Act, according to Katherine Pruitt, author of the report and the American Lung Association’s national senior director for policy.

Emission controls have helped, she said, as has the country’s continuing move away from its reliance on coal for its energy needs. Even something simple as the increase in the number of people who work from home has played a role.

“The Biden administration has set themselves a good, strong to do list of things that will help with environmental justice and climate protection,” Pruitt said. “They’re moving kind of slow, though. So we’d like them to pick up the pace.”

Despite the progress, not everyone was lucky enough to live in a county with good ozone levels. More than 100 million people live in counties that get an F for ozone smog, the report says.

Western and Southwestern cities are the most ozone-polluted, with 10 of the 25 most-polluted cities in California. New York, Chicago and Hartford, Connecticut, were the only three on that list east of the Mississippi River.

The five metropolitan areas with the worst ozone pollution are Los Angeles-Long Beach, California; Visalia, California; Bakersfield, California; Fresno-Madera-Hanford, California; and Phoenix-Mesa, Arizona.

Particle pollution, the other form of pollution tracked in the report, still seems to be a significant issue for the US.

Often hard to see, particle pollution is a mix of solid and liquid droplets that may 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.

Particle pollution 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 even been associated with a higher risk of depression and anxiety, studies show.

The new report says the number of people living in counties with failing grades for daily spikes of particle pollution was the highest it has been in a decade. Nearly 64 million live with these kind of unhealthy spikes in counties that get failing grades.

One driver of the high amounts of particle pollution are the wildfires that have consumed hundreds of thousands of acres. In 2021 alone, there were 14,407 fires, many in the West, according to the National Interagency Fire Center. There used to be a wildfire season, experts say, but now they happen year-round.

Those fires are why the regions with the highest concentrations of air pollution are largely in the West.

When the American Lung Association started producing its report in 2004, 106 counties in 30 states got failing grades for daily spikes in particle pollution. Fewer than half were in eight states west of the Rocky Mountains. Today, 111 counties in 19 states got Fs for spikes in particle pollution, and all but eight counties are in the West, the report says.

Urban centers in the Rust Belt and the industrialized East had gotten the most failing grades in the early 2000s, but many have cleaned up and now get passing grades.

Bakersfield, California, displaced Fresno as the metropolitan area with the worst short-term particle pollution, but Fresno did not suddenly develop cleaner air. That city still had the most-polluted label for year-round particle pollution, tied with Visalia, in the agricultural San Joaquin Valley.

Los Angeles is still the city with the worst ozone pollution, according to the report, as it has been for all but one of the years included in the report.

California has some of the more progressive environmental legislation in the country, but the climate crisis has not been kind to the state, said Tarik Benmarhnia, an air pollution and wildfire researcher at the University of California, San Diego, who did not work on the new report.

“All these cities like Bakersfield and Visalia are in a valley near the forests that are seeing big fires. There’s also intense agricultural and industrial work there, so they unfortunately have all the worst conditions for air pollution,” Benmarhnia said.

There are some newcomers to the list of the 25 areas with the most particle pollution, including Denver and Fargo, North Dakota. Reno, Nevada; Yakima and Spokane, Washington; and Boise, Idaho; all made the worst list this year.

San Luis Obispo, California; Portland, Oregon; and Seattle and Bellingham, Washington; all moved off the list of worst 25 cities.

Residents in the cities ranked worst for particle pollution are living with more of it, the report says. In the top 25 cities with the worst air, the average number of days residents were exposed to high levels of fine particle pollution increased to a weighted average of 18.3, up from 16.5 in last year’s report.

East of the Mississippi, Pittsburgh and Lancaster, Pennsylvania, were the two worst metropolitan areas in the country, posting more days high in fine particle pollution in this year’s report.

Not everyone experiences pollution the same way in the US. Regardless of the region, communities of color bear the brunt of the problem.

Specifically, although people of color make up 41% of the overall US population, they are 54% of the nearly 120 million people living in counties with at least one failing grade for unhealthy air. And in the counties with the worst air quality, 72% of the 18 million residents are people of color, the report said.

Other research has also shown this trend. On maps that lay out areas with high levels of air pollution and where communities were redlined – areas where Black people were forced to live – they line up perfectly, Pruitt said.

“Then, the other aspect is, when you have a community of color that is a voluntary community, people aren’t forced to live there, those are communities that tend to have less of a voice, so decision makers place polluting sources in those communities because there’s not as much howling by people with power when they do. So those communities get the highways; they get the landfills; they get the fence lines,” she said.

There’s a myth that only poor communities live with disproportionate pollution levels, says Chris Tessum, a professor in the Civil and Environmental Engineering Department of the University of Illinois. Tessum, who was not involved in the new report, says race really is the determining factor.

“The thinking is that people with more money will buy better property, which has lower air pollution and that’s just the way of the world or whatever, but that’s just kind of emphatically not, not true,” he said.

Communities need to play a key role in making decisions to help clean air, Tessum said.

“People that have the power will use that power to benefit themselves and not the people that have been historically overburdened,” he said.

The new report says government and residents can make a difference. One suggestion is to leverage Inflation Reduction Act funding to help reduce emissions at ports and to invest in zero-emission heavy-duty vehicles and in infrastructure that would improve air quality monitoring.

States can also use the Clean Air Act authority to adopt the California zero-emissions standards for cars and trucks, the report says.

At the federal level, agencies must finalize stronger limits on air pollution to truly protect public health and advance environmental justice, the report says, including standards to move the country toward zero-emissions vehicles. The EPA also has to set stronger national standards for particle pollution and ozone, the researchers say.

Pruitt said she knows firsthand how better policies can work. She said growing up before the Clean Air Act, pollution was so high that she could see it every time she stepped outside. Today, the pollution is not nearly as visible.

“I’m in my mid-60s, and of course, air pollution was very tangible when I was young, but these days, thank goodness it isn’t. Most people don’t see it,” she said. Unless a person has a lung condition, they may not even feel it.

But just because you can’t see it or feel it doesn’t mean it’s not there. Pruitt encourages people to remember that no level of pollution is safe. The World Health Organization estimates that the combined effects of ambient air pollution and household air pollution are associated with 6.7 million premature deaths annually.

“People don’t really recognize that what they’re breathing is impacting their health,” Pruitt said.

EPA proposes new regulations on toxic gas used to sterilize spices and medical equipment | CNN

The US Environmental Protection Agency on Tuesday proposed a set of new restrictions on facilities that use the cancer-causing chemical ethylene oxide, a colorless, odorless gas that is used to sterilize medical devices and spices.

The agency said the new rules, which have not been finalized, would help to reduce ethylene oxide gas that these facilities release by 80%, bringing emissions below a Clean Air Act standard for elevated cancer risk.

Communities exposed to ethylene oxide gas have been pushing the EPA to put tighter controls on plants that use ethylene oxide gas.

In 2018, an EPA report found that dozens of communities across the nation faced elevated cancer risks because of trace of amounts of ethylene oxide released into air as part of the sterilization process.

The EPA issued the report on the new risks without issuing a news release, as it had done for the same report in years past. Some affected communities learned of the risk through a health assessment conducted by the Agency for Toxic Substances and Disease Registry, a division of the US Centers for Disease Control and Prevention, and media reports. A report from the EPA’s Office of the Inspector General found that some communities weren’t alerted to their risk by EPA at all.

The elevated risk became apparent after a two-decade long review of the toxicity of ethylene oxide by scientists in EPA’s Integrated Risk Information System (IRIS) program.

While the EPA acknowledged that ethylene oxide was more dangerous that had been previously understood, it continued to use an older set of rules to regulate facilities that released ethylene oxide as well as companies that manufacture it.

The proposed rules aim to better align regulations on the producers and users of ethylene oxide with the cancer risk posed by the chemical. They follow a set of proposed rules issued by EPA last week that would put new controls on facilities that manufacture ethylene oxide.

Taken together, the two sets of rules would remove 77 tons of ethylene oxide emissions a year, an 84% reduction compared with 2020 levels, EPA Deputy Administrator Janet McCabe said in a call with reporters on Tuesday.

Environmental watchdog groups applauded the proposed restrictions, but noted that they don’t go far enough to protect vulnerable communities, where residents are often low-income and disproportionately people of color.

“These regulations are long overdue, by almost a decade. I’m relieved and pleased that the EPA has finally issued proposed standards that are based on their own scientists’ recommendations on an updated, higher cancer risk value. If enacted, these updated regulations would reduce emissions in fenceline communities,” said Darya Minovi, a senior researcher scientist at the Union of Concerned Scientists.

“When the EPA issues the final rule, they should throw the net wider. The standard should cover a larger range of facilities to include off-site warehouses that often store recently sterilized equipment that continue to release ethylene oxide, but aren’t regulated for their air emissions.”

Minovi also said the EPA should require fenceline monitors – devices that constantly read the air outside of facilities to make sure that toxic gas isn’t drifting into neighborhoods.

Jaime Rukstales, a member of the Illinois grassroots advocacy group Stop EtO in Lake County – one of the communities impacted by ethylene oxide pollution – says the EPA needs to impose tougher restrictions on “all types of facilities that impact the health of our communities … including sterilizers, manufacturers and warehouses near our homes, schools and businesses.”

Some off-site warehouses used to store newly sterilized products have registered high levels of ethylene oxide due to off-gassing of the products.

Meanwhile, chemical manufacturers sued the EPA in February over its updated hazard assessment for ethylene oxide. The industry wants the agency to use a less protective standard developed by the Texas Commission on Environmental Quality.

AdvaMed, a group that lobbies for the interests of medical device manufacturers, warned that more regulations could pose problems for patients.

“If new EPA regulations force sterilization facilities to close, patients could face treatment delays as sterile technology supplies, such as pacemakers and surgical equipment, fall short,” Scott Whitaker, president and CEO of AdvaMed, said in a comment posted on the group’s website.

The EPA said some commercial sterilizers have already made the planned changes.

“Many sterilization and health care facilities are already taking the steps outlined in the proposal and have seen emissions drop significantly,” McCabe said.

Most facilities have taken action to control ethylene oxide blown out of sterilization chambers through exhaust vents known as “back vents” but only 25% to 33% of sterilizers are controlling so-called fugitive emissions, ethylene oxide that escapes or leaks into room air, said Jonathan Witt, an environmental engineer and technical lead on EPA’s review of the National Emissions Standards for Hazardous Air Pollutants.

“So we think it’s a good sizable chunk of the industry, but still a little ways to go,” Witt said on a call with reporters.

If the rules go into effect, sterilizers would have 18 months to make the changes, which the EPA said is an accelerated time frame under the Clean Air Act.

AdvaMed’s Whitaker says that’s not enough time.

“It could take many months for abatement equipment to arrive. Supply chains and manufacturing are still recovering from the pandemic,” he noted in the statement.

In issuing the proposed rules, the EPA said it aimed to strike a balance between lowing cancer risks for impacted communities and workers who use ethylene oxide while preserving “critical sterilization capabilities.”

The proposed rules would apply to 86 commercial sterilization facilities in the United States that use ethylene oxide gas to fumigate spices and medical devices.

The EPA says 20 billion medical devices – mostly single-use, disposable items used in health care such as catheters, gloves and surgical gowns – are sterilized using ethylene oxide.

The US Food and Drug Administration is actively exploring alternatives to the use of the gas, the EPA said on Tuesday, but some devices still can’t be sterilized any other way.

In proposing the new rules, EPA said its new analysis found that exposure to ethylene oxide, or EtO, on the job significantly increased cancer risks for workers in sterilization facilities and those who apply ethylene oxide in health care facilities.

“Now, a new EPA analysis shows that there may also be significant risks to workers who handle [ethylene oxide] and people who live, work or go to school near places where EtO is used in sterilization. And failing to take action to address these risks is simply unacceptable,” EPA Administrator Janet McCabe said on a call with reporters.

The additional lifetime cancer risk for a worker exposed to ethylene oxide for eight hours a day, 240 days a year for 35 years was between 1 in 10 and 1 in 36 for workers in sterilization facilities; and between 1 in 12 and 1 in 25 for workers exposed to ethylene oxide in health care facilities.

To help lower those risks, the proposed rules require greater use of personal protective equipment for workers and new controls to decrease the amount of ethylene oxide in indoor air.

Whitaker from AdvaMed, the medical device industry group, said the cancer risk for employees exposed to ethylene oxide on the job is overstated and disregards “the strong employee protections already in practice.”

Companies will also be required to use new real-time monitoring methods to confirm that these pollution controls are working inside facilities. These controls can measure ethylene oxide in indoor air down to 10 parts per billion. If ethylene oxide levels climb above this threshold, everyone in the workplace would be required to wear protective equipment.

They will also lower the amount of ethylene oxide that can be used for each sterilization cycle. The EPA is proposing to limit the application rate for ethylene oxide to no more than 500 milligrams per liter of air.

The rules would eliminate some niche uses of ethylene oxide where alternatives exist, including its use in museums, archival settings, beekeeping, some cosmetics, and in musical instruments.

The EPA will take public comment on the new rules for 60 days. The agency will also host a virtual public webinar on May 1 to discuss its proposed rules and new risk assessment.

Price Of Economic Growth: Rising Air Pollution Is Choking Indian Cities And Killing People

Post By zittrexstore Business AIR, choking, cities, economic, Growth, Indian, killing, people, Pollution, price, rising No Comments

India has become the world’s fastest-growing economy, but air pollution–the bane of industrial societies–is choking its cities and taking a huge toll on its people’s health. And despite years of efforts, the country’s attempts to improve air quality are not making much of an impact and healthcare experts are raising alarm about the impact of toxic air.

The number of smog-filled cities in India continues to rise with each passing year. More than 130 cities now face pollution levels below national standards, according to a report by the Center for Research on Energy and Clean Air.

Capital Delhi is now one of the most polluted cities in the world. Financial hub Mumbai, although near the sea, has also been hit hard by pollution and is witnessing a surge in health issues ranging from throat infection and dry cough to breathing difficulties among citizens.

Air quality in Bengaluru, India’s tech capital, went downhill last October, escalating health concerns among residents.

“It is very obvious that the bulk of air pollution is caused by construction activities, vehicles, and manufacturing or industrial activities, and there is no policy in the direction of reduction, mitigation or discouragement of any of these,” civic activist Sandeep Anirudha said in a critique of the government’s efforts.

Air pollution–a slow killer

Air pollution is reducing the life expectancy of people in Delhi by 10 years. The Air Quality Life Index indicates that particulate matter (PM) pollution reduces life expectancy more than communicable diseases, the World Economic Forum said in a report last year. Particulate matter are microscopic solids or liquid droplets that can be inhaled by humans and cause serious health issues.

While there has been a decline in Covid-19 cases in Indian cities, a rise in cases of respiratory and heart issues are increasing the strain on the healthcare system. Children and the elderly aged 60 and above are more likely to have health complications.

Sudden deaths due to heart attacks have increased in India due to long-term exposure to air pollution, particularly PM2.5, according to a study published in Jama Network Open.

Researchers found long-term PM 2.5 exposure is directly linked with an increased risk of acute myocardial infarction (AMI). Experts suggest that tiny air pollutants can cause narrowing of the heart arteries, which can result in heart stoppage.

“My asthma has intensified after breathing the air pollutants over the past few months,” Kartik Verma, a resident of Delhi-National Capital Region, told International Business Times. “The air around my residence is continuously degrading, thanks to the incessant construction and vehicular pollution in the area. Doctors suggest if I don’t take immediate precautionary measures and change my surrounding, I may be at risk of severe lung and heart issues.”

India’s polluting industries

Booming industrialization, rising urbanization and associated commercial activities are also contributing to air pollutant emissions and poor air quality in the country.

More than half, or 51%, of air pollution in India is the result of industries, as per a research analysis. More than 6% of India’s industries reportedly don’t comply with environmental standards, threatening harmful emissions and discharge of effluents, as per Times of India.

Dr. Uday Sanglodkar, a senior consultant hepatologist at Mumbai’s Global Hospital, highlighted how rampant construction and traffic fumes have been impacting the city’s air quality. He said long-term exposure to smoke and pollution is weakening the lungs and other organs of growing children and pregnant women. There is a rise in cases of chronic and persistent coughs, alongside the annual flu season, across the city.

“It makes us think how pollution is contributing to health concerns among people of all age groups,” Dr. Sanglodkar told International Business Times.

Even as the government of India has implemented various policy measures to reduce industrial emissions, the extent to which these measures are helping remains debatable. In recent years, various ministries have implemented programs to promote clean technologies in key sectors, such as the National Electric Mobility Plan 2020 and energy efficiency labeling for energy-intensive home appliances.

The most significant measure was the announcement of the National Clean Air Program in 2019, which mandates 122 cities with high pollution levels to design city-specific action plans to reduce PM2.5 emissions by 20-30% by 2024 compared to 2017 levels. While the policy was announced with high expectations, its ground-level implementation has remained shaky. The plan lacks a concise funding strategy as budgetary allocations have remained stagnant and inadequate.

Looking at the regional level, Bruhat Bengaluru Mahanagara Palike, Bengaluru’s civic body, for instance, allocated $54.5 million to implement fresh measures aimed at controlling the rising AQI levels in the city. And the Delhi government is planning an extensive system, including anti-smog guns to water sprinklers mounted on mini-trucks, to control pollution on roads and construction sites in the city this summer.

The effectiveness of these measures will also depend on various factors, including the willingness of the citizens to bring and adopt the required changes to reduce air pollution at the home level.

Dr. Sanglodkar suggested certain preventive measures to tackle the harmful effects of pollution on health. Wearing masks in outdoor spaces and avoiding smoking are among them.

“The government must take rigorous measures to curb construction activities and limit the emissions from vehicles to put rising air pollution under check. Also, there is a need for creating meticulous awareness among the general public about the need to take active participation in minimizing the impact of air pollution,” he added.

Same story across the globe

A recent study released by Lancet Planet Health said nearly everyone, approximately 99.82% of the global population, is currently exposed to unhealthy levels of harmful air pollutants (particulate matter 2.5 or PM 2.5). The findings of the study published Monday highlight the growing need for public health officials and policymakers to focus on measures to curb leading sources of air pollution. The study confirmed only 0.001% of the world’s population breathes considerably acceptable air, Japan Times reported.

As the fifth-largest global mortality risk factor, air pollution has emerged to be a prominent public health concern in other major economies, including China and U.S. Harmful air pollutants contribute to millions of premature deaths and other health hazards every year in countries around the world. It has caused about one-tenth of global deaths, with the overall death toll exceeding 5 million. Some 21% of China’s health concerns were linked to air pollution due to rapid industrialization, which is 8% higher than the U.S. PM 2.5 has been identified as the main cause of smog in the U.S., which is being inhaled by people every day, raising the risk of lung and heart disease.

Daily pollution levels have increased in Australia, New Zealand and Latin America, with more than 70% of days globally surpassing safe levels.

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.

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.

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.”

Rise in space tourism, rocket launches pose new threat to ozone layer, researchers warn

Post By zittrexstore World Climate, Environment, Features, new zealand, Pollution, Space No Comments

New research shows that increased space travel could undo efforts to repair the hole in the ozone layer. Successful global coordination to ban harmful chlorofluorocarbon (CFC) gasses and restore the ozone was a rare climate triumph – but can it be replicated in the face of a potential new threat?

Researchers in New Zealand have warned that expected increases in space travel are likely to damage the Earth’s ozone layer if coordinated action is not taken.

Although emissions from rocket launches are currently relatively small compared to other human activities, they could grow to rival emissions from the aviation industry in coming decades, researchers from the University of Canterbury wrote in a new article published in the Journal of the Royal Society of New Zealand.

“Many emissions products from rocket launches are ozone-depleting, and the threat to the ozone layer could be significant,” they wrote.

The ozone is a protective layer of the atmosphere that sits 15 to 50km above the Earth’s surface and absorbs almost all of the sun’s UV light, which can be harmful to humans and wildlife.

CFCs and other harmful chemicals have depleted the ozone layer, notably over both the Arctic and Antarctic. But the degradation is most pronounced in the southern hemisphere, where a significant hole in the ozone layer has formed every spring since 1979.

A billion-dollar industry

Rocket launches pose a danger to the Earth’s protective layer as they emit damaging gasses and particles “directly into the middle and upper atmosphere, where the protective ozone layer resides”, the researchers wrote.

In addition to harmful substances released by burning rocket fuel, space debris from parts that burn up upon their return to Earth also disperses damaging particles into the atmosphere.

Without developments in rocket and fuel technologies, these emissions are set to increase as the space sector grows rapidly in every region of the world.

Around 70 nations now have space agencies and private space companies are also becoming more common. The “billionaire space race” – led by Richard Branson’s Virgin Galactic, Jeff Bezos’ Blue Origin and Elon Musk’s SpaceX – is pushing satellite and space tourism initiatives that “suggest an upwards trend in global launch totals”, the researchers wrote.

“We’ve seen rocket launches almost doubling in three years and there are missions aiming towards launching up to as many as three rockets a day, which is just unprecedented,” said Dr. Eloise Marais, associate professor in physical geography at University College London.

“With the potential for growth in the space sector, there is reason to be concerned; the pollution coming from rocket launchers and disposal of space junk isn’t regulated under any framework.”

Globally, smaller companies are also proliferating. India alone had a total of total of 368 space tech businesses as of May 2021, due to heavy investment in its own commercial space industry.

The global space launch market was valued at almost $14.5 billion in 2022 and is expected to almost triple, to close to $43 billion, by 2030.

An environmental success story

There is strong precedent for introducing regulatory framework to protect the atmosphere.

In 1987, the international Montreal Protocol aimed to reduce damage to the ozone layer by phasing out harmful CFCs, which were widely used for refrigeration, solvents, in aerosols and for industrial activities.

“It’s been quoted as the most successful global environmental treaty there’s ever been,” says Martyn Chipperfield, professor at the University of Leeds and senior researcher at the UK’s National Centre for Earth Observation. Adoption of the treaty has avoided “catastrophic ozone depletion”, he said.

A UN report in January confirmed the global phase-out of nearly 99 percent of banned ozone-depleting substances. As a result, the hole in the ozone is shrinking and is on track to recover within four decades.

Without the protocol it is estimated that two-thirds of the ozone layer would have been destroyed by 2065, and the amount of damaging solar radiation reaching the Earth would have more than doubled.

This rare success story has been touted as an example for other environmental progress. “Ozone action sets a precedent for climate action,” said the World Meteorological Organization’s secretary-general, Petteri Taalas. “Our success in phasing out ozone-eating chemicals shows us what can and must be done – as a matter of urgency – to transition away from fossil fuels, reduce greenhouse gases and so limit temperature increase.”

Goodwill and action?

However, the circumstances of the Montreal treaty made it uniquely poised for widespread adoption and success. “Industry was on board with the controls, because they could see there was a move to control CFCs and they had alternatives, and there was a multilateral fund which enabled non-developed countries to transition to other alternatives without financial penalties,” Chipperfield said.

“And the initial protocol was very modest in its aims; it said, as the science becomes clearer, we can have amendments to make it stronger. And in due course, there were these amendments.”

By contrast, there is no obvious clean replacement for rocket fuels currently in use and little impetus to regulate a small – but rapidly expanding – sector, even though there are pressing environmental concerns to consider.

One of these is the black carbon that is released into the atmosphere in the form of soot particles as a result of each rocket launch. These particles can linger in the higher levels of the atmosphere, where there is no rain to wash them out, for two and a half years before they settle back to earth.

“They are very, very efficient at absorbing the sun’s rays, so they warm up the local atmosphere and they offset the energy balance of the earth and impact climate,” said Marais.

As the space industry grows, researchers in New Zealand are calling for coordinated global action to measure emissions from launch vehicles and share data to build a picture of the environmental risk rocket launches may pose.

They also suggest that effects on ozone should be incorporated into industry best-practices for rocket design and development.

“Ozone recovery has been a global success story. We want to ensure that future rocket launches continue that sustainable recovery,” said a co-author of the research, Dr. Laura Revell, an associate professor in environmental physics.

There is hope among experts that more steps can be taken. “People do care about the ozone layer,” said Chipperfield. “You’d hope there would be some goodwill and action taken like there was last time it was threatened.”

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.

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.

Paul Polman: The world needs a Marshall Plan to fight climate change–and politicians are failing to show ambition. Business can’t afford to wait

Post By zittrexstore Business big oil, business climate change, Climate change, COP27, corporations climate change, Environment, global warming, greenwashing, net zero, paul polman, Pollution, stop oil now No Comments

The COP27 climate talks in Sharm el-Sheikh were a missed opportunity. The pledge to keep global temperature rises under 1.5 degrees is just about alive, affirmed by G20 leaders in Bali–but there’s no clear plan to deliver it.

The Sharm deal doesn’t include a commitment to phase out all fossil fuels or any guarantee that emissions will peak by 2025. Current national carbon reduction targets get us closer to a devastating three-degree rise. A powerful group of blockers–mainly oil-rich governments and companies–were out in force.

There were bright spots. By creating a new fund for “loss and damage,” rich countries are finally taking some financial responsibility for producing most of the emissions already causing mayhem in poorer countries. This is a significant breakthrough for a multilateral system dangerously low on trust. Let’s hope the money follows.

More governments committed to methane cuts. Enhancing nature and reforming food systems were formally recognized as part of the climate fight. And tighter measures were proposed to avoid greenwashing.

However, the urgency of the crisis is clearly still lost on many of our political leaders. Collectively, they are failing to deliver the ambition and action on which our planet and future depend. This situation is not going to magically improve. Next year’s COP28 will be held in the oil-rich United Arab Emirates–and will be just as easily hijacked.

There will be no great superpower pact to save us: despite diplomatic baby steps between Washington and Beijing, their cooperation will be limited as long as Russian tanks are in Ukraine and America fears for Taiwan’s security. Even with the U.S., Australia, and Brazil back at the table, ongoing troubles in the global economy and high inflation threaten to push global warming down domestic agendas (even though tackling climate change is the best way to stabilize energy and food prices).

Business literally can’t afford to sit back and wait for politics to get its act together. Climate isn’t just an environmental issue: it’s the economy, stupid. Extreme floods, heat waves, wildfires, and hurricanes cost billions. They send impoverished nations further into debt, while crippling supply chains, disrupting global trade, and destroying the labor force. Whether you are a C-Suite executive, an investor, or the WTO, you have a major interest in getting the world onto a more stable path. There are tremendous gains waiting for those who move quickly. The shift to a low-carbon economy can add trillions of dollars to global growth each year, and create millions of jobs.

Even as politics stalls, business can still push ahead. Beyond companies getting their own houses in order, there are three immediate things business leaders can do.

The first is advocating for much-needed reform of our global financial architecture. The idea that we will need a Marshall Plan-style intervention to finance the shift to a greener economy is starting to gain traction. CEOs can help bring it into the mainstream.

The fringes of Sharm saw much discussion of Barbados Prime Minister Mia Mottley’s Bridgetown Agenda, which calls for climate to be fully integrated into the mandates of the post-WW2 Bretton Woods institutions, which would dramatically increase the resilience and capacity of the Global South.

Professor Lord Stern has calculated that, if developed countries significantly increase grants and low-interest loans through expanded aid, it could attract $1 trillion of private investment to help finance the transition. Such proposals warrant urgent investigation–and business can demand it.

Second, senior executives can do more to lead vital partnerships for change. Across industry, government, and civil society, we will have to collaborate on climate in ways we never envisaged. It’s starting to happen–and it’s time to ramp up the speed and scale of collaboration.

In Bali, we helped launch the Global Blended Finance Alliance, including the biggest ever single climate transaction, which mobilizes $20bn from governments and private finance to support Indonesia’s effort to close coal mines and peak its emissions early.

Led by the Rockefeller Foundation (where I sit on the board) another coalition of investors, entrepreneurs, and public officials will bring clean energy to 1 billion people, including many in Africa.

And business and farmers aim to dramatically scale regenerative agriculture and improve livelihoods within seven years through the Regen10 initiative.

Third, is bringing more young people to the table, fast. The young activists I met in Sharm were sharp, determined, and sick of being patronized. They are powerful–as employees and consumers, as our sons and daughters, as the next generation of leaders, and as voters. Many are frustrated with the political process and look to the private sector to empower them in a new, intergenerational alliance that has an impact on the real economy. Here too, business can act: put them on boards, on panels, in leadership positions, and in every room where decisions affecting their futures will be taken.

There’s no need to feel hopeless–but we must recognize that our politics is failing to deliver vital climate action. We must find other ways to close the ambition gap, get the money moving, get business driving urgent coalitions, and make sure young people are firmly in the driving seat. Then, it will be up to politics to catch up.
