E.P.A. Proposes Limits on Nitrogen Oxides

News Feed
Friday, November 22, 2024

A rule proposed by the Environmental Protection Agency on Friday could better protect communities against pollution from natural gas plants.For the first time in almost two decades, the rule would update emission limits of nitrogen oxides, a group of gases that are harmful air pollutants produced from burning fossil fuels. The emissions can contribute to asthma and respiratory infections, especially in children, older people and those who are immunocompromised.“These stronger standards are necessary to better protect nearby communities’ health, and the power sector has already shown that the additional pollution controls can affordably and reliably do the job,” said Joseph Goffman, the E.P.A.’s assistant administrator for air and radiation, in a statement.The proposal was created to limit nitrogen oxide emissions from all new turbines built at power plants and industrial facilities, along with any existing turbines that are modified or reconstructed after the proposal takes effect.The stricter standards could also lead to reductions in other types of pollution, like particulate matter and ozone, by lowering the amount available to react with other volatile organic compounds.“Ultimately, the healthiest option for families across the nation is for power plants to stop burning fossil fuels altogether and for utilities to invest in clean and reliable renewable energy,” said Holly Bender, the Sierra Club’s chief energy officer, in a statement.Despite advancements in pollution control technology and an increased understanding of how nitrogen oxide harms human health, limits on the amount of nitrogen oxide that can be released have not been updated since 2006.While the Clean Air Act requires the E.P.A. to review protections against air pollution from power plants every eight years, the nitrogen oxide limits lagged for 18 years. The new standard is the result of a 2022 lawsuit brought by the Environmental Defense Fund and the Sierra Club that requires the E.P.A. to take a final action on new limits by November 2025, following a public comment period.The fate of the proposed standard is uncertain after January, when the Trump administration takes over.“It should not go without noting that the incoming Trump administration has repeatedly vowed to slash rules and regulations issued by agencies across the government,” said Julie McNamara, deputy policy director for the Climate and Energy Program at the Union of Concerned Scientists, in a statement.The E.P.A. estimates the proposed standard would reduce nitrogen oxide emissions by more than 2,600 tons by 2032, producing roughly $45 million in public health benefits each year.

Air Quality, Not Just Fitness Level, Impacts Marathoners' Finish Times

By Dennis Thompson HealthDay ReporterTHURSDAY, Dec. 26, 2024 (HealthDay News) -- Runners put a lot of thought into how much they must eat and drink to endure a 26.2-mile marathon, properly fueling their bodies to sustain a record-setting pace.But the quality of the air they huff and puff during endurance events could also play a key role in their performance, a new study says.Higher levels of air pollution are associated with slower average marathon finish times, according to findings published recently in the journal Sports Medicine.“Runners at that level are thinking about their gear, their nutrition, their training, the course, even the weather,” lead researcher Elvira Fleury, a doctoral student at Harvard University, said in a news release. “Our results show that those interested in optimizing athletic performance should consider the effect of air pollution, as well.”Runners’ average finish times on a marathon steadily decreased for every increase in particle pollution of one microgram per cubic meter of air, results show.Men finished 32 seconds slower on average for every increased unit of air pollution, and women finished 25 seconds slower, researchers found.These effects also appeared to be more pronounced in faster-than-average runners, researchers said.“This means that air pollution can be a health risk not just for those who are elderly or susceptible — it can negatively affect even the most healthy and well-trained among us,” senior researcher Joseph Braun, a professor of epidemiology at Brown University, said in a news release from the college.For the study, researchers analyzed data from U.S. public marathons conducted between 2003 and 2019, involving more than 1.5 million male runners and more than 1 million female runners.The research team compared the runners’ finishing times with air quality data captured on event days, including the amount of particle pollution in the air along different points of the marathon route.“This really sophisticated spatial-temporal model of particulate matter allowed us to plot pollution at every mile of every course,” Fleury said. “Without a model like this, it wouldn't have been possible to look at so many different marathons in different states across different years.”Researchers specifically looked at levels of fine particle pollution, which are airborne particles smaller than the width of a human hair or grain of fine beach sand, according to the Environmental Protection Agency.These airborne particles are typically generated by fossil fuels burned by cars and power plants, although in recent years, wildfires have contributed to such pollution.Previous studies have shown that particle air pollution is associated with overall risk of death, as well as risk of heart disease, breathing problems and lung cancer, researchers said.Air pollution could be harming marathon runners’ performance by causing increases in blood pressure, constricted blood vessels, impaired lung function, and perhaps even short-term changes in brain function, researchers speculated.“People who can complete a marathon are generally quite healthy, and we can assume they have honed their cardiorespiratory fitness,” Braun said.“This study revealed a negative impact from air pollution, even at levels below current health-based standards, on these very healthy people,” Braun continued.These findings support efforts to reduce pollution emissions by shifting motor vehicles and power plants away from fossil fuels, researchers concluded.SOURCE: Sports Medicine, journal study, Dec. 18; Brown University, news release, Dec. 18, 2024Copyright © 2024 HealthDay.

Forty Years After the Bhopal Disaster, the Danger Still Remains

In many ways, we all live in Bhopal now. We must continue to fight for a future in which we all have the right to live in healthy environments.

Forty years ago this month, a Union Carbide pesticide factory in Bhopal, India, sprung a toxic gas leak, exposing half a million people to toxic fumes. Thousands of people lost their lives in the immediate aftermath, with the death toll climbing to more than 20,000 over the next two decades. Countless others, including children of survivors, continue to endure chronic health issues. In the United States, the events in Bhopal ignited a grassroots movement to expose and address the toxic chemicals in our water, air, and neighborhoods. In 1986, just two years after the disaster, this growing awareness led Congress to pass the first National Right to Know Act, which requires companies to publicly disclose their use of many toxic chemicals. In India, Bhopal victims have had a long struggle for justice. In 1989, survivors flew to a Union Carbide shareholders meeting in Houston to protest the inadequate compensation for the trauma they’d suffered. The settlement awarded each Bhopal victim was a mere $500—which a spokesperson for Dow Chemical, Union Carbide’s parent company, called “plenty good for an Indian.”  Union Carbide had the survivors arrested before they could enter the meeting. Meanwhile, their abandoned chemical factory was still leaking toxic chemicals into the surrounding neighborhoods and drinking water.  Nevertheless, Bhopal survivors never stopped fighting. They opened a free clinic to treat the intergenerational health effects caused by the disaster. They marched 500 miles between Bhopal and New Delhi. They staged hunger strikes. They created memorials to the disaster and established a museum to ensure that the horrors of their collective past are not forgotten.    The survivors even obtained an extradition order for Union Carbide’s former CEO, Warren Anderson, but the U.S. government never acted on that request. Forty years later, the factory in Bhopal has never been properly cleaned and is still leaking poison.  Unfortunately, the kinds of chemicals that flow through the veins of Bhopal survivors also flow through ours. The petrochemical industry has brought us together in a perverse solidarity, having chemically trespassed into places all over the world. According to one figure, Americans are exposed to dangerous chemical fires, leaks, and explosions about once every two days. In one dramatic example in early 2023, a rail tanker filled with vinyl chloride derailed in East Palestine, Ohio, forcing the evacuation of 2,000 residents.  Nearly all Americans now carry toxic substances known as PFAS in our bodies. These have been linked to cancer, liver and kidney disease, and immune dysfunction. And the continued burning of fossil fuels is killing millions of people each year around the world through air pollution.  Petrochemical and fossil fuel companies know they can only survive if they avoid liability for the damage they are doing to our health and the planet’s ecosystems. That’s why they are heavily invested in lobbying to prevent any such accountability. Polluting industries are certain to have strong allies in the coming Trump Administration, which plans to open even more land to fossil fuel production and, under the blueprint for conservative governance known as Project 2025, to slash environmental and public health regulations. But we can take inspiration from the people of Bhopal, whose fierce commitment to health and justice sparked a global movement. Earlier this month, on the fortieth anniversary of the Bhopal disaster, congressional allies of this movement including U.S. Senator Jeff Merkley, Democrat of Oregon, and U.S. Representatives Pramila Jayapal, Democrat of Washington, and Rashida Tlaib, Democrat of Michigan, introduced a resolution designating December 3 as National Chemical Disaster Awareness Day. “Chemical disasters are often the result of corporations cutting corners and prioritizing profits over safety,” said Merkley, who chairs the U.S. Senate Environment and Public Works subcommittee. “These catastrophes cloud communities with toxic fumes, upending lives and threatening the health and property of those living and working close by.” He called for “stronger laws to prevent chemical disasters and keep our communities and workers safe.” This growing global alliance, which has been called the largest movement for environmental health and justice in history, is fighting for a future in which everyone has the right to live in a healthy environment. It’s a movement that unites us all. Because in many ways, we all live in Bhopal now. This column was produced for Progressive Perspectives, a project of The Progressive magazine, and distributed by Tribune News Service. Gary Cohen is the president of Health Care Without Harm and a long time member of the International Campaign for Justice in Bhopal. Read more by Gary Cohen December 18, 2024 3:25 PM

Study Miscalculation Has Everyone Talking about Black Plastic Spatulas Again. Experts Are Still Concerned

The scientists behind a popular study on the health effects of flame retardants in black plastic cooking utensils and toys made a calculation error but still say their revised findings are alarming

Should you throw out your black plastic spatula? A recent study that reported alarming levels of several flame retardants in common black-colored plastic items (including cooking utensils, toys and hair products) had many people suddenly taking stock of their inky array of plastic kitchenware and considering wood or metal alternatives. And the reasons for the concern were understandable: the study’s findings, published in Chemosphere, highlighted potential health effects from exposure to the flame retardants, particularly decabromodiphenyl ether (decaBDE)—a chemical the U.S. Environmental Protection Agency banned in 2021 for its apparent links to cancer and reproductive, developmental and immunologic toxicity effects.But this week the study’s authors issued a correction that suggests exposure to decaBDE from the tested products isn’t as close to the EPA’s safety reference level as they initially thought. The decaBDE exposure they estimated from the screened products is still correct, but it’s one tenth of the reference dose. The study had miscalculated the comparison by an order of magnitude.The amount of flame retardants in such products is “not as harmful, with respect to the EPA guidance, as [the researchers] originally stated, although, with these chemicals, they may be harmful when you’re exposed to small amounts over a long period of time,” says Andrew Turner, a biogeochemist at the University of Plymouth in England, who wasn’t involved in the research and studies the disposal and recycling of plastic consumer goods. “It’s difficult to put numbers on these chemicals.”On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.The study authors issued an apology for the mistake in which they maintained that the “calculation error does not affect the overall conclusion of the paper.”“Our results still show that when toxic additives are used in plastic, they can significantly contaminate products made with recycled content that do not require flame retardancy,” says Megan Liu, a co-author of the recent study and science and policy manager at Toxic-Free Future, an environmental health research and advocacy group. “The products found in this study to contain hazardous flame retardants included items with high exposure potential, such as things that touch our food, as well as toys, which come in contact with kids.”Why might some black plastics contain flame retardants? Flame retardants are required in certain products (often including computers, TVs and other common electronic items) to meet fire safety regulations. To reduce the amount of e-waste and fossil fuels needed to make new plastics, some of these items are recycled into black plastics. But the problem is that “you could also recycle the flame retardants and other chemicals that are associated with that plastic,” says Stuart Harrad, an environmental chemist at the University of Birmingham in England, who wasn’t involved in the paper. “Now that’s fine to some degree, I suppose, if you’re only recycling the plastic into uses like TV sets, where you need to meet fire safety regulations. But the point is here is that that isn’t happening.”The new study’s main goal was to identify any flame retardant chemicals in various common products. The researchers screened 203 items, ranging from plastic sushi take-out trays to toy necklaces—and found 17 of them were contaminated with high levels of flame retardants. Fourteen of those products contained high levels of decaBDE.The U.S. has largely banned decaBDE and other polybrominated-diphenyl-ether-based flame retardants. New electronic goods use safer flame retardants, but older electronics that contain decaBDE could still be in many households or might have been only recently tossed out for recycling, Turner says. “When you talk about some electronic devices, they last quite a long time,” he adds. These older devices might only be reaching recycling plants now.The new study’s findings generally line up with past evidence that recycled plastics—and flame retardants—can end up in toys and cooking utensils, Harrad says. But it’s been unclear whether the mere presence of flame retardants in a cooking utensil pose any health threat to humans; there are many contributing factors, including the source, the dose, the duration of exposure and any other chemicals that may be present. In a 2018 study Harrad and his colleagues tested potential exposure from black plastic cooking utensils and found that uptake through the skin from simply holding them was negligible. But when they tested them in prolonged cooking experiments with hot oil, about 20 percent of the flame retardants in a utensil transferred into the oil on average. “That’s really because the oil, particularly hot oil, is going to be a pretty good way of extracting these chemicals,” Harrad says.How did the miscalculation occur?The authors of the new study estimated humans’ potential exposure to decaBDE from the plastic products by using the calculation in Harrad’s 2018 study. They applied this calculation to the median levels of decaBDE detected in the products they tested. This wound up being an estimated 34,700 nanograms per day of decaBDE. They then compared that figure with the EPA’s reference dose of 7,000 nanograms per kilogram of body weight per day. (Some researchers note that this measurement was derived from lab tests and animal models, not direct human testing). To better assess human risk, the scientists calculated a reference dose based on a 60-kg (132-pound) person and initially found 42,000 ng per day, a value alarmingly close to the 34,700 ng per day of exposure they estimated from the new data. But 7,000 multiplied by 60 is actually 420,000. This may have been a simple math error, but the correction massively reduces how close the amount of exposure is to the maximum acceptable limit.The figure with the miscalculation was “contextualizing the levels that we saw in our study, thinking that it could be helpful for people,” Liu says. “This was really just one part of our study that isn’t even part of our key findings.”She and her co-authors have emphasized that the error shouldn’t detract from one of the study’s main conclusions: that none of these flame-retardant chemicals, especially those that have been banned, should be found, in any amount, in these products in the first place.“They're probably banging their head in frustration when they found out they made that calculation error,” Harrad says, adding that the rest of their findings “were perfectly plausible.”“The study does highlight the fact that we’ve not sorted this out yet—that we’re still finding these chemicals coming through into new goods that contain recycled plastics,” Harrad says. “We do need to step up our efforts to isolate these chemicals from waste and make sure that they don't get recycled.”So should you really ditch your black plastic spatula? Harrad says you should avoid leaving it in a hot pan or pot for long periods of time. Some experts don’t recommend reheating food in black plastic containers, although studies haven’t confirmed if this causes chemicals to leach into food. Importantly, “if you see that your black utensil is damaged in any way, just [get rid of it] and go for something else,” Turner says—pieces of the plastic could potentially break off into food.When looking for new cooking ware, Turner says that it’d be more sustainable, and potentially safer, to reduce the use of black plastic items and opt for a material or color that’s more easily recyclable. Liu says wood, stainless steel or silicone products are some safer alternatives. She adds, however, that people can’t “shop” their way out of a larger societal issue. “We can’t expect that everyone can immediately switch over to safer alternatives,” Liu says. “That’s ultimately why we’ve been calling on greater regulatory action at both the corporate and government level to regulate and restrict these harmful chemicals.”

Microplastics may be leading to lung and colon cancer, study shows

New research published Wednesday in the journal Environmental Science and Technology offers evidence that microplastics are harming human health.

When a car rolls down a freeway, a fine spray of microplastics spews out from its tires. When you wash your clothes, millions of tiny synthetic microfibers spill into waterways.And those tiny pieces of plastic may be harming our health, a new study shows.In a paper published Wednesday in the journal Environmental Science and Technology, researchers at the University of California at San Francisco evaluated dozens of studies in mice and humans to learn how microplastics may be harming digestive, respiratory and reproductive health. They found that these shards — which are now virtually everywhere in the air we breathe, the water we drink, and the food we eat — are suspected of links to colon cancer and lung cancer.

In His Own Home

Heavily armed officers of the University of Florida police department in Gainesville, FL, responding to a 911 call from a neighbor who heard screams, break into the campus apartment of Ghanaian graduate student, Kofi Adu-Brempong. Clad in SWAT gear and ready to attack, they see the disabled doctoral student, sitting with a metal table leg in his hand and within a minute of entry, shoot the unarmed man in the face. Adu-Brempong, who because of childhood polio, needed a cane to walk, and had been suffering from mental illness, now has severe facial injuries, and is charged with resisting arrest. He is guarded outside his hospital door, his legs shackled together when going to the bathroom. The officer who shoots Kofi, and who had previously been caught cruising through town throwing eggs at residents of a Black neighborhood, is not suspended or fired. Student protests lead the administration to drop charges but calls for revoking SWAT-like teams on campus go unheard. Kofi’s shooting is not an isolated incident but part of an ongoing pattern of police brutality against Blacks and a stark reminder of the dangers of increasingly militarized campuses nationwide. In His Own Home came out of outrage by a small group of concerned community members committed to seeing social justice happen on a local level. This documentary is an educational and organizing tool, especially calling for our communities to be safe from violence by racist and over-armed police.
