Concentrations of per-and polyfluoroalkyl substances (PFAS) in private well drinking water and serum of individuals exposed to PFAS through biosolids: The Maine Biosolids Study
Science
20 Oct 2025 | Environ. Pollut.
Individuals living near farmland where PFAS-contaminated biosolids were historically applied had elevated PFAS in their private well water and blood, especially PFOA, which showed a strong water-to-serum correlation, demonstrating that biosolids can be a major exposure source and that some people may still have high serum levels even when their current water meets standards.

Profiles of per- and polyfluoroalkyl substances in firefighter turnout gear and their impact on exposure assessment
Science
20 Oct 2025 | Environ Sci Process Impacts
Firefighter turnout gear contains varying levels of PFAS chemicals that accumulate more in older gear and the inner moisture barrier, increasing with wear, heat, and abrasion, which raises firefighters’ potential exposure risks.

PFAS in bottled water from China: High prevalence of ultrashort-chain compounds, health risks, and global insights
Science
19 Oct 2025 | J Hazard Mater
Bottled water across China contains high levels of ultrashort-chain PFAS such as TFA and PFPrA, highlighting growing global concerns and the need for stronger drinking water regulations.

Changes in the levels and predictors of per-and poly-fluoroalkyl substances in maternal plasma, relative to timelines of EPA PFOA Stewardship
Science
18 Oct 2025 | Environ. Int.
PFOS, PFOA, PFHxS, PFHpS, and Me-PFOSA-AcOH declined over time after EPA’s PFOA Stewardship Program, but other PFAS such as PFNA, PFUnA, PFDeA, PFDoA, and GenX increased especially among non-White mothers, and higher levels were linked to eating fish/shellfish and vegetables, working, and having carpet or pets during pregnancy, showing that policies reduced some PFAS but exposure sources and inequities remain.

Emerging PFAS in Songbird Eggs from a Belgian Hotspot Site
Science
17 Oct 2025 | Environ Res
Songbird eggs collected near a fluorochemical plant in Belgium contained record-high levels of both legacy and emerging PFAS, including newly detected compounds like SF5-PFSAs and ether-substituted PFAS, showing that PFAS continue to accumulate in wildlife and should be included in future monitoring and risk assessments.

Per-and polyfluoroalkyl substances (PFAS) in food and its contribution to human exposure.
Science
15 Oct 2025 | Curr. Opin. Food Sci.
PFAS in common foods like seafood, eggs, meat and contaminated local produce can raise blood levels above health-based guidance values, with 14% of European teenagers already exceeding these limits, showing that food is a major exposure source and that better monitoring, regulation and dietary strategies are needed.

Assessment of trifluoroacetic acid in tap water from Besançon (France) and bottled water from France, Italy, and Romania
Science
14 Oct 2025 | Discover Water
TFA, an ultra-short chain PFAS, was found in 100% of tap water samples from Besançon (540–3,800 ng/L, average 1,164 ng/L) and in most bottled waters at lower levels, showing that tap water is a major source of exposure and that this persistent, unregulated chemical needs monitoring and inclusion in drinking water policies.

Current knowledge about per-and polyfluoroalkyl substances (PFAS) in the atmosphere: Fate, analytical methods and research priorities
Science
13 Oct 2025 | Chemosphere
PFAS can escape into the air from factories, firefighting foams, landfills, and wastewater plants, move long distances in gases and tiny particles, cycle back through rain and sea spray, accumulate indoors, and expose people by breathing or skin contact even far from the source.

From carboxylates to chlorinated sulfonates: Contrasting fate and treatment prospects of GenX and F53B in WWTPs
Science
13 Oct 2025 | Science of The Total Environment
In wastewater systems, GenX was found to largely persist in the aqueous phase with minimal degradation, while F-53B partitions to sludge and undergoes limited breakdown, and advanced treatments like UV with sulfite or electrochemical oxidation outperform conventional processes, though byproducts and limited field data remain concerns.

A review of the key impacts of deforestation and wildfires on water resources with regard to the production of drinking water.
Science
12 Oct 2025 | Hydrology
Deforestation and especially wildfires can release pollutants into water, but wildfires pose an added threat because firefighting foams and burn residues introduce PFAS that contaminate both surface water and groundwater, making drinking water treatment far more difficult and costly.

Per- and polyfluoroalkyl substances exposure in hexavalent chromium exposed workers and the effects of exposure mixtures on oxidative stress and genomic instability
Science
12 Oct 2025 | Environ Pollut
Workers in chrome-plating and similar industries are exposed to toxic hexavalent chromium alongside very high levels of PFAS such as PFOS and PFDA, and this combined exposure is linked to early signs of oxidative stress and DNA changes that may increase the risk of cancer, mitochondrial damage, and impaired DNA repair over time.
