Findings help decipher mechanisms through which ‘forever chemicals’ cause disease, aiding in treating health problems

New research suggests exposure to some common Pfas or “forever chemical” compounds causes changes to gene activity, and those changes are linked to health problems including multiple cancers, neurological disorders and autoimmune disease.

The findings are a major step toward determining the mechanism by which the chemicals cause disease and could help doctors identify, detect and treat health problems for those exposed to Pfas before the issues advance. The research may also point toward other diseases potentially caused by Pfas that have not yet been identified, the authors said.

Some Salisbury, Maryland, residents say the contaminated water from Perdue Farms’s local plant has sickened them

Wastewater from an industrial soya bean farm and processor has poisoned a Maryland town’s drinking water with Pfas, several lawsuits allege, raising questions about residents’ health and “forever chemical” pollution from industrial agricultural operations nationwide.

Perdue Farms acknowledged that its 300-acre Salisbury, Maryland, operation is polluting local waters, but the chemicals’ sources have not been confirmed. It appears the Pfas is in part also coming from some combination of sludge used as fertilizer and pesticides, attorneys for plaintiffs say.

Research provides more evidence that food is a potentially overlooked exposure route to toxic ‘forever chemicals’

Produce grown in home gardens around a North Carolina PFAS plant contain dangerous levels of the chemicals, new research has found, providing more evidence that food is a potentially overlooked exposure route to the compounds, especially when grown near polluters.

The study’s authors say findings point to much of the contamination resulting from air emissions, which research increasingly suggests is an underestimated source of PFAS pollution.

Fifty-one sites in NSW have significant PFAS contamination requiring continued monitoring and remediation, EPA tells Senate inquiry

Experts and water providers have called for a broad ban on so-called “forever chemicals” at a Senate inquiry into PFAS, warning of environmental harm and increasingly costly removal.

The Water Services Association of Australia’s executive director, Adam Lovell, said a ban should be imposed on PFAS in non-essential consumer products. “We need to reduce now, as much as possible, how much PFAS is in the environment.

Water quality expert calls for wider PFAS ban as NSW community seeks blood tests on ‘poisoned’ land

Cost of fixing ‘forever chemical’ pollution should be borne by manufacturers and polluters, not governments and consumers, expert tells Senate inquiry

A water quality expert says the Australian government should expand a planned ban of PFAS as a New South Wales indigenous community called for funding for blood tests for people living on “poisoned” land.

PFAS (per- and polyfluoroalkyl substances), a group of several thousand synthetic compounds, are found in a wide variety of products including waterproof fabrics, food packaging, hygiene products and firefighting foam. They are sometimes referred to as “forever chemicals” because they are slow to break down and persist in the environment for extended periods.

Exclusive: Newly uncovered documents reveal chemicals giant was aware ‘environmentally neutral’ products did not biodegrade

The multibillion-dollar chemicals company 3M told customers its firefighting foams were harmless and biodegradable when it knew they contained toxic substances so persistent they are now known as “forever chemicals” and banned in many countries including the UK, newly uncovered documents show.

From the 1960s until 2003, 3M made foams containing PFOS and PFOA (perfluorooctane sulfonate and perfluorooctanoic acid), synthetic chemicals that can take tens of thousands of years to degrade in the environment and have been linked to cancers and a range of other health problems such as thyroid disease, high cholesterol, hormonal problems and fertility issues.

Findings highlight how built environment in low-income neighborhoods presents multiple PFAS exposure routes

New research aimed at identifying which US neighborhoods face increased exposure to toxic PFAS “forever chemicals” found those living near “superfund” sites and other major industrial polluters, or in areas with limited access to fresh food, generally have higher levels of the dangerous compounds in their blood.

The study looked at hundreds of people living in southern California and found those who do not live within a half mile of a grocery store have 14% higher levels of PFOA and PFOS – two common PFAS compounds – in their blood than those who do.

EPA says Tucson’s drinking water is contaminated but air force claims agency lacks authority to order cleanup

The US air force is refusing to comply with an order to clean drinking water it polluted in Tucson, Arizona, claiming federal regulators lack authority after the conservative-dominated US supreme court overturned the “Chevron doctrine”. Air force bases contaminated the water with toxic PFAS “forever chemicals” and other dangerous compounds.

Though former US Environmental Protection Agency (EPA) officials and legal experts who reviewed the air force’s claim say the Chevron doctrine ruling probably would not apply to the order, the military’s claim that it would represents an early indication of how polluters will wield the controversial court decision to evade responsibility.

Ex-president’s allies and Project 2025 propose restrictions to EPA’s ability to protect public from toxins like PFAS

A second Donald Trump presidency would represent a serious threat to dealing with the toxic impact of PFAS “forever chemicals”, as well as other toxins, and could be a danger to the health of millions of Americans, experts and environmental campaigners warn.

For example, over the last year, the Environmental Protection Agency developed groundbreaking drinking water limits for highly toxic PFAS compounds, and designated several of the “forever chemicals” as hazardous substances, a move that will force industry to clean up its pollution. The steps represent a major win for the water quality and taxpayers, but a new Trump administration would likely shred the rules.

Study that researchers say highlights chemicals’ ubiquity also shows PFAS association with seafood and red meat

New research aimed at identifying foods that contain higher levels of PFAS found people who eat more white rice, coffee, eggs and seafood typically showed more of the toxic chemicals in their plasma and breast milk.

The study checked samples from 3,000 pregnant mothers, and is among the first research to suggest coffee and white rice may be contaminated at higher rates than other foods. It also identified an association between red meat consumption and levels of PFOS, one of the most common and dangerous PFAS compounds.
