Scientists raise alarm after analyzing samples from migratory birds: 'Not particularly good news'
Researchers are finding more "forever chemicals" than ever before in migratory birds' bodies and food sources.
As the Norwegian University of Science and Technology reported, forever chemicals, or PFAS, are increasingly prominent inside the birds and in the food they eat.
The team analyzed samples from 25 migratory birds and also from 30 shellfish in areas where the birds often eat. The test area was in China, along a migration route with rapidly declining bird populations.
"The biggest increase is in the livers of wading birds," said postdoctoral fellow Junjie Zhang, who collaborated on the study, via Phys.org. "We found up to 180 times more PFAS than previously. … This suggests that previous methods have not been good enough at detecting certain types of PFAS."
The researchers published their findings in the Journal of Hazardous Materials.
Discovering more PFAS than previously expected is concerning because of how harmful these substances can be.
Since these chemicals degrade extremely slowly and never break down, they accumulate in natural areas and inside the bodies of animals and people. Certain per- and polyfluoroalkyl substances have been linked to increased risks of cancer, kidney disease, developmental problems, and other conditions.
Companies produce products for human consumption that contain PFAS, and they have been appearing in unexpected places that impact our daily lives.
This study's findings are also significant because they highlight a new and promising method for analyzing samples and detecting PFAS, according to the university report. Accurate detection will allow us to understand the origin of PFAS better and take proactive measures to target them.

Scientists uncover exciting new method to remove dangerous chemicals from the body: 'Feasible, accessible and economical'
In a hopeful breakthrough for public health, researchers found that dietary fiber may help reduce PFAS — toxic "forever chemicals" — from the human body. As reported by The Guardian, the pilot study showed that increased fiber intake can lower levels of two of the most widespread and harmful PFAS: PFOA and PFOS. These pollutants are commonly found in water, food packaging, and household products, and they have been linked to serious health issues, including cancer, birth defects, and kidney disease. PFAS, short for perfluoroalkyl and polyfluoroalkyl substances, are called forever chemicals because they don't naturally break down and can remain in the body for decades. The study's authors believe dietary fiber forms a gel in the digestive system that blocks PFAS from being absorbed, allowing them to exit when you go to the bathroom — similar to how fiber helps remove bile acids. Importantly, the study found that both soluble and insoluble fibers were needed, and oat beta-glucan, a common supplement, was mentioned as a helpful source. Timing is also important, as fiber works best when taken with meals, when bile production is highest. While fiber didn't work as well for "short-chain" PFAS (which are excreted more easily through urine), it was highly effective at reducing levels of long-chain types such as PFOA and PFOS — the types most commonly found in people's blood. This method also appears to be a gentler alternative to treatments such as cholestyramine, a cholesterol drug sometimes used to treat PFAS exposure but known to cause uncomfortable digestive issues. By contrast, fiber has a wide range of health benefits and is easy to integrate into your daily routine. This promising discovery joins other innovative solutions such as an LED method used to break down PFAS and ultraviolet purification used to break down PFAS in water. "The key is that this is feasible, accessible and economical," said Boston University's Jennifer Schlezinger, a co-author of the study. She added that early results are "very promising," and a larger study is underway. People online were impressed with the findings. "Wild how something as simple as fiber could help flush out toxic forever chemicals," one person said on Instagram. "The link between fiber intake and reducing 'forever chemicals' is such an important topic. More research like this could shape our understanding of diet and health. Thanks for sharing!" added another. Do you worry about having toxic forever chemicals in your home?

Researchers make critical breakthrough after using powerful satellite to track dangerous pollution: 'Large-scale missions'
Research published this March in the journal Environmental Research Letters has demonstrated an impressive new way to zero in on heavy polluters and monitor evolving pollution problems, according to a release via Researchers at the Max Planck Institute and Heidelberg University have established a method for using a German satellite, the Environmental Mapping and Analysis Program, or EnMAP, to determine the amount of atmospheric carbon dioxide (CO2) and nitrogen dioxide (NO2) present in the same area "with an unprecedented spatial resolution." These common air pollutants are generally released from the same source, so measuring one or the other independently has been challenging to date. This team leveraged the new technique to assess emissions from power plants. The technology used for such measurements has typically "only [achieved] a spatial resolution of 3 to 5 kilometers" (about 1.9 to 3.1 miles), according to the release. But the EnMAP can achieve an "exceptionally high level of spatial detail" of a 30-meter (98-foot) square, producing more precise and usable data. NO2 isn't technically a greenhouse gas like CO2, methane (CH4), or nitrous oxide (N2O), though it is harmful when in the home. Meanwhile, because NO2 is so often emitted alongside CO2, it is often used to measure CO2 based on an assumed ratio. With independent measuring made possible with the EnMAP, readings can now provide more accurate and insightful information. The EnMAP has been in the sky for three years as of April and has been key to numerous climate-related studies. The paper's co-authors are hopeful about the future applications of the method they have developed using the satellite. "Our study shows how satellites with high spatial resolution can contribute to the targeted monitoring of industrial emissions in the future—in addition to large-scale missions such as the European CO2M satellite," said research leader Thomas Wagner in a statement. With accurate data being key to catching polluters as well as tracking potential improvements, there's the possibility for innovative measurement techniques to play a role in not only penalties for offenders but also in setting more pro-environment policies down the line.

Bill would cover ‘Forever Chemical' exposure at bases under VA benefits
A bipartisan bill would allow veterans with health issues caused by exposure to 'forever chemicals' at U.S. military bases to be treated as service-connected disabilities, which would further open the door to health care and benefits compensation for those impacted. Forever chemicals, more technically known as polyfluoroalkyl substances, or PFAS, are long-lasting chemicals that break down slowly. They are found in many everyday objects, food, and in air, water, and soil around the world, according to the U.S. Environmental Protection Agency. The bill, titled 'Veterans Exposed to Toxic PFAS Act,'' or the ''VET PFAS Act,' would designate exposure to PFAS as a service-connected condition for veterans, making them eligible for disability compensation through the Department of Veterans Affairs. It would also allow military dependents, including those 'in utero while the mother' resided at a base with PFAS exposures, to be eligible for hospital care and medical services for certain diseases and conditions, according to the text of the bill. If passed, the legislation would be a major expansion of health conditions and illnesses for which veterans could receive VA care and disability benefits. The bill was introduced in the House on May 29 by New York Rep. Josh Riley, a Democrat, and Rep. Mike Lawler, a Republican, and builds upon measures from the Promise to Address Comprehensive Toxics Act. The PACT Act, passed in 2022, was the largest expansion of service-connected health conditions eligible for VA care, including service members exposed to burn pits during Iraq and Afghanistan deployments, for Vietnam War veterans exposed to Agent Orange-related chemicals, and very specific instances of base exposures. The Department of Defense has identified 718 bases with known or suspected PFAS release. The military estimates that PFAS investigation and cleanup costs could come to more than $9.3 billion in fiscal year 2025, which was more than triple the estimate in 2022. Since 2017, the Defense Department has spent around $2.6 billion to address PFAS, according to a Government Accountability report from February. The bill states that covered health conditions would be identified by the Secretary of Veterans Affairs and the agency administrator of the Department of Health and Human Services' registry for toxic substances and diseases. Their suggestions would come from studies directed by Congress in the annual defense bill for fiscal year 2018, which are ongoing from the Centers for Disease Control. The CDC's website on health investigations states that existing research suggests that high levels of PFAS could lead to increased cholesterol, changes in liver enzymes, pre-eclampsia in pregnant women, decreases in birth weight, and increased risks of kidney and testicular cancers. The bill specifically calls for health care coverage of perfluorooctanoic acid exposures for veterans diagnosed with high cholesterol, ulcerative colitis, thyroid disease, testicular cancer, kidney cancer, and pregnancy-induced hypertension. Other iterations of the legislation have been previously introduced. Some Democratic senators have expressed interest in crafting their own PFAS bill, but nothing formal has been introduced yet, a spokesperson for the Senate Veterans Affairs Committee told Task & Purpose. The issue of forever chemicals on military bases and their health impacts on military families has been gaining support in Congress. In April, Senate Democrats held an event on the Hill with former service members and their families who called for a broadening of the PACT Act. At the April event, military families described cancers and other illnesses they believe are the result of PFAS exposures, including former bases like George Air Force Base, California, which later became superfund sites, a designation by the EPA as one of the most polluted sites in the U.S. Despite the designation, the families based there were never notified of their potential exposure. The PACT Act also established a framework for the VA to establish presumptive conditions without an act of Congress through the federal rule-making process. The VA began the process for defining PFAS exposure as a presumptive health condition for VA care with a federal register notice in September. However, an executive order issued by President Donald Trump in January paused all federal rule-making.
