People locked their windows, donned face masks and cranked air purifiers on high to escape what became known as Beijing's "air-pocalypse."
The air quality was so bad, and became so globally infamous, that Chinese leaders launched a multibillion-dollar "war against pollution."
A decade on, those efforts are paying dividends. China's pollution levels in 2021 had fallen 42% from 2013, according to a new report released Tuesday, making it a rare success story in the region, where pollution is getting worse in some parts, including South Asia.

"There are many factors that we are navigating through, such as the fact that youth are more disconnected and disinterested compared to previous generations," Dietz said, according to Military.com. "The declining veteran population and shrinking military footprint has contributed to a market that is unfamiliar with military service resulting in an overreliance of military stereotypes."
In September, Pentagon leaders sounded the alarm on its recruiting challenges.
"The Department anticipates we will collectively miss our recruiting mission despite accessing more than 170,000 remarkable young men and women" in the fiscal year that ended Sept. 30, Stephanie Miller, deputy assistant secretary of defense for military personnel policy, told the Senate Armed Services Personnel Subcommittee. "This constitutes an unprecedented mission gap and is reason for concern."
To understand the physiological systems that may be contributing to these changes in behavior, Ross' team investigated how widespread the microplastic exposure was in the body, dissecting several major tissues including the brain, liver, kidney, gastrointestinal tract, heart, spleen and lungs. The researchers found that the particles had begun to bioaccumulate in every organ, including the brain, as well as in bodily waste.
"Given that in this study the microplastics were delivered orally via drinking water, detection in tissues such as the gastrointestinal tract, which is a major part of the digestive system, or in the liver and kidneys was always probable," Ross said. "The detection of microplastics in tissues such as the heart and lungs, however, suggests that the microplastics are going beyond the digestive system and likely undergoing systemic circulation. The brain blood barrier is supposed to be very difficult to permeate. It is a protective mechanism against viruses and bacteria, yet these particles were able to get in there. It was actually deep in the brain tissue."
That brain infiltration also may cause a decrease in glial fibrillary acidic protein (called "GFAP"), a protein that supports many cell processes in the brain, results have shown. "A decrease in GFAP has been associated with early stages of some neurodegenerative diseases, including mouse models of Alzheimer's disease, as well as depression," Ross said. "We were very surprised to see that the microplastics could induce altered GFAP signaling."
She intends to investigate this finding further in future work. "We want to understand how plastics may change the ability for the brain to maintain its homeostasis or how exposure may lead to neurological disorders and diseases, such as Alzheimer's disease," she said.
The study was published in the International Journal of Molecular Science. It was supported by the Rhode Island Medical Research Foundation, Roddy Foundation, Plastics Initiative, URI College of Pharmacy, George and Anne Ryan Institute for Neuroscience, and the Rhode Island Institutional Development Award (IDeA) Network of Biomedical Research Excellence from the National Institute of General Medical Sciences of the National Institutes of Health.

The analysis, using data from more than 100 countries spanning nearly two decades, indicates that increased air pollution is linked with rising antibiotic resistance across every country and continent.
It also suggests the link between the two has strengthened over time, with increases in air pollution levels coinciding with larger rises in antibiotic resistance.
"Our analysis presents strong evidence that increasing levels of air pollution are associated with increased risk of antibiotic resistance," researchers from China and the UK wrote. "This analysis is the first to show how air pollution affects antibiotic resistance globally." Their findings are published in the Lancet Planetary Health journal.
Antibiotic resistance is one of the fastest-growing threats to global health. It can affect people of any age in any country and is already killing 1.3 million people a year, according to estimates.
The main drivers are still the misuse and overuse of antibiotics, which are used to treat infections. But the study suggests the problem is being worsened by rising levels of air pollution.
The study did not look at the science of why the two might be linked. Evidence suggests that particulate matter PM2.5 can contain antibiotic-resistant bacteria and resistance genes, which may be transferred between environments and inhaled directly by humans, the authors said.
Air pollution is already the single largest environmental risk to public health. Long-term exposure to air pollution is associated with chronic conditions such as heart disease, asthma and lung cancer, reducing life expectancy.
Short-term exposure to high pollution levels can cause coughing, wheezing and asthma attacks, and is leading to increased hospital and GP attendances worldwide.
Curbing air pollution could help reduce antibiotic resistance, according to the study, the first in-depth global analysis of possible links between the two. It also said that controlling air pollution could greatly reduce deaths and economic costs stemming from antibiotic-resistant infections.

In the months after benzene was reported in sunscreens, recalls were undertaken by Coppertone and by Johnson & Johnson (of certain Neutrogena sunscreens and one Aveeno sunscreen). In January 2023, Banana Boat also expanded its recall of products found to contain benzene.
In addition, tests published in 2023 of 50 sunscreen products (purchased in 2021) found that 80% contained benzene, with three containing relatively higher amounts.
FDA guidance suggests that no level of benzene is safe, and it is not permitted in these or other products. A study by Health Canada's Bureau of Chemical Hazards has shown that the application of sunscreen specifically increases the absorption rate of benzene through the skin. Benzene is known to cause cancer in humans according to the U.S. Centers for Disease Control and Prevention, the U.S. Department of Health and Human Services, the World Health Organization, and other regulatory agencies. The National Institute for Occupational Safety and Health (NIOSH) defines benzene as a carcinogen and lists "inhalation, skin absorption, ingestion, skin and/or eye contact" as exposure routes.

Not any level of PFAS exposure will lead to these health consequences, of course. And even heavy exposure does not necessarily mean that you're going to get sick; putting in your contact lenses every morning is not a sure road to cancer or high cholesterol. But enough of these ills have turned up in enough people exposed to PFAS that the EPA and the larger community of scientists are justifiably worried about them—especially because of their persistence in the environment.
"This entire class of chemicals is probably the most persistent class of manmade chemicals that have ever been made," says Scott Belcher, an associate professor of biological sciences at North Carolina State University, who was a scientific advisor for the contact lens study. "Once they're there, they're not going away."
PFAS are included in uncounted products from clothing to furniture to pizza boxes to food wrappers to cooking utensils to electronics to fire-fighting foam to shoes and much, much more. The chemicals are used to make pots and pans non-stick; textiles more durable and stain resistant; food packaging resistant to grease; shoes and clothing water-resistant; and paper and cardboard stronger, among multiple other uses. So widespread is the planet's PFAS load that, according to one 2022 study in Environmental Science and Technology, the chemicals actually fall from the sky in rain, with the clouds having picked up PFAS in water evaporating from contaminated oceans.
"Every raindrop has PFAS in it," says Belcher. "It is really earth-shaking for me and eye-opening for folks."
For most people, however, everyday life inside their homes is where they're most likely to encounter PFAS on a regular basis. Here is a non-exhaustive list of some personal possessions and parts of your household that are exposing you to forever chemicals:
The U.S. Centers for Disease Control and Prevention (CDC) lists many brands in these product categories as harboring PFAS, which are added to the products because the chemicals make them more durable, water resistant, or smoother spreading. But those qualities come at a price: some of the products, like dental floss and shampoo, are used in the mouth or near the eyes—mucus membranes that readily absorb contaminants. Multiple brands of both floss and shampoo now advertise themselves as PFAS-free, and the number of such products is growing.
In February, Mamavation and Environmental Health News conducted a study of PFAS in menstrual care products, including tampons, pads, sanitary napkins and period underwear, and found most of them contaminated to one degree or another with the forever chemicals. (Mamavation is not a scientific organization but a self-established wellness site, and Leah Segedie, its founder and editor, is not a scientist, but an author and consumer activist. Still, she conducts her PFAS studies only in conjunction with certified labs.)
In March, a study published in Environmental Science and Technology Letters found PFAS in most brands of toilet paper sold around the world, a huge problem in the U.S. where over 19 billion lbs. of wastepaper are flushed away annually, posing a massive disposal and wastewater contamination problem. (A bidet eliminates the problem of toilet paper almost entirely, though most U.S. households are not equipped with them.)
PFASs are a group of about 10,000 mainly man-made substances used in numerous applications in the EU. These applications include textiles, food packaging, lubricants, refrigerants, electronics, construction and many more.
In the EU, some PFAS are already regulated under REACH and POP legislation (see Table 1) and the SVHC list, while other groups are being proposed for restrictions (see Table 2).
he current larger proposals for restriction (see Table 3) will cover a greater number of substances with specific exemptions and different dates of entry into force for specific uses.
PFAS are defined as any substance that contains at least one fully fluorinated methyl (CF3-) or methylene (-CF2-) carbon atom without any H/Cl/Br/I attached to it.
A substance that only contains the following structural elements is excluded from the scope of the proposed restriction: -CF3-X or X-CF2-X', where X = -OR or -NRR' and X' = methyl (-CH3), methylene (-CH2-), an aromatic group, a carbonyl group (-C(O)-), -OR'', -SR'' or –NR''R''', and where R/R'/R''/R''' is a hydrogen (-H), methyl (-CH3), methylene (-CH2-), an aromatic group or a carbonyl group (-C(O)-).

Based on death certificate data compiled by the Centers for Disease Control and Prevention, the research found that fatal falls in this age group had increased from 10,097 in 1999, and at a rate that more than doubled in about two decades — from 29 deaths per 100,000 people to 69 deaths per 100,000 people, according to research published in the journal JAMA.
The research notes that falls have become the leading cause of injury for the age group. More than 1 in 4 people 65 or older fall each year, according to the CDC (although the agency says less than half tell their doctor). About 1 in 5 falls results in a serious injury, such as broken bones or a head injury, and 3 million older adults are treated in emergency rooms each year because of falls.
Product manufacturers are responsible for ensuring compliance with regulatory requirements. But as the focus on PFAS in the U.S. intensifies, and states adopt policies that may not be consistent with one another, manufacturers may find it challenging to determine compliance. Therefore, relevant enterprises should understand these requirements as early as possible and investigate the presence of PFAS in their products. Manufacturers must know what chemicals are being added to their products.

The U.S. Environmental Protection Agency ("EPA") yesterday announced a proposed rule to limit greenhouse gas ("GHG") emissions from electric generating units ("EGUs"). The proposal seeks to drastically reduce emissions of GHG and conventional emissions while promoting the use of carbon capture and sequestration ("CCS") and hydrogen co-firing technologies. This proposed rule is part of the Biden Administration's larger regulatory effort to transition the American economy toward "low carbon" technology.
The proposed rule treats new EGUs differently based on level of output and targets certain existing fossil-fuel-fired combustion turbines (both simple cycle and combined cycle).
The proposed rule contains three primary parts: (1) strengthening CO2 standards for new gas-fired combustion turbines, based on three new categories; (2) providing emissions guidelines for existing gas plants that have a capacity of 300 MW and operate at a more than 50 percent capacity factor; and (3) covering existing steam generation units—mostly coal—by requiring those EGUs to choose between new control technologies or retirement.
Consistent with Clean Air Act Section 111, the proposed New Source Performance Standards and emissions guidelines "reflect the application of the best system of emissions reduction [("BSER")] that, taking into account costs, energy requirements, and other statutory factors, is adequately demonstrated." To this end, the EPA's newly proposed rule also seeks to repeal the Affordable Clean Energy ("ACE") Rule, stating, among other rationales, that the BSER therein are no longer appropriate for existing coal-fired EGUs.
The proposed rule would create different standards based on three categories of new gas EGUs and enhance standards for certain existing gas EGUs.
New and Reconstructed Fossil-Fuel-Fired Stationary Combustion Turbines: EPA proposes three subcategories for new gas plants, based on how heavily a plant is used. For new low-load "peaker" units—defined as operating at below 20 percent capacity factor—EPA proposes as BSER the use of a "lower-emitting fuel," such as natural gas or distillate oil.
For new intermediate load units—defined as operating at between a 20 and 50 percent capacity factor—EPA proposes a phased standard. The first phase establishes as BSER the performance of a highly efficient combustion turbine. The second phase establishes BSER as co-firing 30 percent (by volume) of "low-GHG" hydrogen by 2032 and 90 percent by 2035. The second phase requires continued use of highly efficient generation. The EPA is soliciting comments as to whether intermediate-load units should be subject to a more stringent third phase that would require higher levels of hydrogen co-firing by 2038.
For new baseload combustion turbines—defined as operating at above a 50 percent capacity factor—EPA proposes as BSER one of two pathways, either co-firing with "low-GHG" hydrogen starting at 30 percent in 2032 and ramping up to 96 percent by 2038, or by achieving a 90 percent CCS rate by 2035.
Existing Fossil-Fuel-Fired Stationary Combustion Turbines: EPA's proposed standards for existing gas plants would only apply to existing EGUs with a 300 MW capacity and at least a 50 percent capacity factor. BSER for these units is based on either the use of CCS by 2035 or co-firing 30 percent (by volume) low-GHG hydrogen by 2032 and co-firing 96 percent low-GHG hydrogen by 2038. The proposed rule does not purport to set new standards for smaller or less frequently used existing gas plants.
The proposed rule requires existing coal-fired EGUs to choose between new control technology or retirement.
EPA relies heavily on CCS and the co-firing of "lower-emitting" fuels to address existing coal-fired generation. The proposed rule would allow operators of existing coal-fired EGUs to forego installation of CCS or certain other emissions control technologies if they commit to near-term retirement of their facilities. The proposed rule would not require any reductions for coal plants closing before 2032, or for plants that commit to retire before 2035 and have a less than 20 percent capacity factor. Existing coal plants that remain online longer than the applicable 2032 or 2035 deadline, but still intend to retire before 2040, may co-fire with natural gas to avoid CCS or other control equipment requirements. Those coal plants intending to remain online through 2040 and beyond must be modified to curb their emissions by 88.4 percent, a level based on achieving 90 percent carbon capture and storage by 2030. This regulatory scheme reflects EPA's view that it is most efficient to deploy CCS technology with EGUs that will operate over a longer period.

Researchers from Tulane University, Louisiana, measured 25 different toxic metals and trace elements in 60 soft beverages, including single fruit juice, mixed fruit juice, plant-based milk, artificial soda, and tea.
The drinks were purchased in New Orleans and are commercially available in supermarkets across the United States.
Researchers found that five of the 60 beverages tested contained levels of a toxic metal above federal drinking water standards.
Two mixed juices had levels of arsenic above the 10 microgram/liter standard. Meanwhile, a cranberry juice, a mixed carrot and fruit juice, and an oat milk each had levels of cadmium exceeding the three parts per billion standard.
In total, 7 of the 25 elements measured by researchers in their study exceeded drinking water standards in some of the drinks, including nickel, manganese, boron, cadmium, strontium, arsenic, and selenium, while lead was detected in more than 93 percent of the 60 samples, although the majority contained levels below one part per billion.
The highest level (6.3 micrograms/kg) was found in a lime sports drink, though that is still below standards for drinking water set by the EPA and the World Health Organization.
Overall, mixed fruit juices and plant-based milks, including oat and almond milk, contained higher levels of toxic metals than other drinks analyzed in the study, researchers said.
Researchers did not identify the specific brands they studied but noted that they can be purchased at local supermarkets and retail stores.
The findings of the study, titled, "Toxic metals and essential elements contents in commercially available fruit juices and other non-alcoholic beverages from the United States," were published in the Journal of Food Composition and Analysis.

Elevated levels of perfluorooctane sulfonate (PFOS), a type of per- and polyfluoroalkyl substances (PFAS), were detected in rainbow smelt sampled from Green Bay. As a result, the DNR and DHS recommend consuming only one meal per week of rainbow smelt from the Bay of Green Bay and its associated tributaries up to the first dam, including portions of the Peshtigo, Oconto and Menominee rivers.
"Eating locally caught fish is a cost-effective way to feed your family a lean, healthy protein. This advisory, like our long-standing mercury and polychlorinated biphenyl (PCB) advisories, is another way to ensure our anglers who eat their catch are provided with the right information to consume fish safely," said Lori Tate, Fisheries Management Section Supervisor.
PFAS are a group of human-made chemicals that have been used for decades in various products, such as non-stick cookware, fast food wrappers, stain-resistant sprays and certain types of firefighting foams that have made their way into the environment.
Health risks may increase when fish with high levels of PFAS are consumed more frequently than recommended. These can include increased cholesterol levels, decreased immune response, decreased fertility in women, and cancers, among other health effects. More information is available on the DHS website.
Following fish consumption advisories will help protect you from consuming excess PFOS, PCBs and mercury. A complete list of up-to-date consumption advisories can be found in the DNR's Choose Wisely booklet.
Additional fish consumption advice and information on the effects of PFAS can be found on the DNR's website.
On December 15, 2022, the United States Environmental Protection Agency (EPA) published its final rule, 87 Fed. Reg. 76578, which formally updates the standard to satisfy "all appropriate inquiries" under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The result is the effective adoption of ASTM E1527-21 as the new Phase I Environmental Site Assessment standard. ASTM E1527-21, went into effect on February 13, 2023, and significantly revises a number of the prior provisions under ASTM E1527-13, and also clarifies a number of key terms and requirements.
Significant changes include:
On March 14, 2023, the United States Environmental Protection Agency (EPA) announced its proposed National Primary Drinking Water Regulation (NPDWR), which would establish legally enforceable levels, called Maximum Contaminant Levels (MCLs), for six PFAS in drinking water. These PFAS chemicals are:
EPA described the proposed MCL of 4 ppt for PFOA and PFOS to be the "lowest feasible level" for which PFOA and PFOS can reliability be measured and removed from drinking water. EPA has also proposed using a "Hazard Index" score as an MCL for a combination of four PFAS compounds - PFHxS, GenX chemicals, PFNA and PFBS. This is the first time that a hazard index approach is being proposed as a federal drinking water MCL standard. In short, a Hazard Index considers how toxic each of the four PFAS are and then uses a site-specific determination based on the specific drinking water concentrations (i.e., the calculation gets complicated).

New research has found that the number of people living in cities without access to safe drinking water worldwide will double by 2050, with an 80 percent increase in demand for water predicted for urban areas by that time, The Guardian reported.
"Water is our common future and we need to act together to share it equitably and manage it sustainably. As the world convenes for the first major United Nations conference on water in the last half century, we have a responsibility to plot a collective course ensuring water and sanitation for all," said UNESCO Director-General Audrey Azoulay on the UN World Water Development Report website.
"Water is a fundamental building block of our world and while it presents vast opportunities for economic growth, it is our responsibility to protect it," said Kelly Speakes-Backman, Acting Assistant Secretary for Energy Efficiency and Renewable Energy. "We must understand the environmental and social impacts as well as benefits of water power technologies—such as hydropower or systems that convert the natural energy from waves, tides, or currents—and we must invest in the infrastructure and humans who will continue to drive technological progress at the nexus of energy and water."
On this day, DOE is proud to announce several ways we are supporting the continued sustainable use of our water-energy resources while identifying new ways to benefit of Americans.

"EPA's top priority is to protect public health and the environment, and today's proposal is a significant step forward to further protect the farmworkers, farmers and pesticide handlers who deliver the fuel, fiber and food that runs America," said EPA Administrator Michael S. Regan. "Farmworker justice is environmental justice, and we're continuing to take action to make sure these communities are protected equally under the law from pesticide exposure."
Application Exclusion Zone
The Worker Protection Standard regulations offer protections to over two million agricultural workers and pesticide handlers who work at over 600,000 agricultural establishments. In 2015, EPA made significant changes to the standard to decrease pesticide exposure among farmworkers and their family members. Less pesticide exposure means a healthier workforce and fewer lost wages, medical bills and absences from work.
Among the changes, the revised standard included a new provision requiring agricultural employers to keep workers and all other individuals out of an area called the AEZ during outdoor pesticide applications. The AEZ is the area surrounding an ongoing pesticide application that people must not enter to avoid exposure. An AEZ moves with the equipment during applications to protect farmworkers and bystanders that could be contacted by pesticides.
In 2020, the previous administration published a rule specific to the AEZ requirements, limiting the applicability of the protections to the agricultural employer's property and shrinking the AEZ size from 100 feet to 25 feet for some ground-based spray applications. Prior to the effective date of the 2020 AEZ Rule, petitions were filed in the U.S. District Court for the Southern District of New York (SDNY) and in the U.S. Second Circuit Court of Appeals challenging the 2020 Rule (now consolidated as case number 20 Civ. 10642). The SDNY issued an order granting the petitioners' request for a temporary restraining order. As a result, the 2020 AEZ Rule has not gone into effect, and the AEZ provisions in the 2015 WPS remain in effect.
Through its review, EPA has determined that the provisions in the 2020 AEZ Rule that weakened protections for farmworkers and nearby communities from pesticide exposure should be rescinded to protect the health of farmworkers, their families, and nearby communities.

"Advances in enhanced geothermal systems will help introduce geothermal energy in regions where, until recently, the use of this renewable power source was thought to be impossible," said U.S. Secretary of Energy Jennifer M. Granholm. "These pilot demonstrations will help us realize the enormous potential of the heat beneath our feet to deliver clean, renewable energy to millions of Americans."
Geothermal energy currently generates about 3.7 gigawatts of electricity in the United States, but a new analysis shows it could provide 90 gigawatts of firm, flexible power to the U.S. grid by 2050, as well as heating and cooling solutions nationwide. This substantial geothermal energy potential is, however, largely inaccessible with conventional geothermal technologies. The use of geothermal energy for electricity requires three elements: heat, fluid, and a permeable section of the Earth's crust. While heat exists everywhere underground, many locations lack adequate water and/or permeability. EGS employ human-made underground reservoirs to enable the fluid flow necessary to draw geothermal energy to the surface, where it can be captured to power homes across the country. Achieving this goal would make geothermal energy a clean, cost-effective option across the country, while spurring progress toward President Biden's goals of 100% carbon-pollution-free electricity by 2035 and net-zero emissions by 2050.

The resource details the Chemical Safety Board's investigation into the October 2019 hydrogen sulfide release at the Aghorn Operating Waterflood Station in Odessa, TX. During the incident, a worker responded to an alarm from a water pump, which was part of the process of extracting natural gas and crude oil. The worker was alone in the pump house when he tried to close process valves to isolate the pump.
"Either before the worker's arrival or during his work, the pump unexpectedly energized, releasing water containing H2S gas into the pump house," the newsletter states. "The H2S concentration reached fatal levels, killing the worker."
OSHA offers likely causes for the incident and lists steps to prevent future incidents. Recommendations include:
Yet despite this knowledge, light pollution has been challenging to document, especially on a global scale. But now, a new study shows that light pollution is rapidly worsening.
The analysis comes from Globe at Night, a citizen science program run by the National Science Foundation's NOIRLab. The study concludes that stars are disappearing from human sight at a stunning rate. By relying on the observations of sky-gazers across the globe, the researchers found that light pollution has had much more of an impact than indicated by satellite measurements.
From the glimmering swath of our home galaxy, the Milky Way, to a multitude of constellations, the human eye should be able to see thousands of stars on a clear, dark night. Yet thanks to light pollution, 80% of people in the United States can't even see the Milky Way swirl of our galaxy anymore.
