Exposure to Legacy Per- and Polyfluoroalkyl Substances from Diet and Drinking Water in California Adults, 2018-2020
Science
14 May 2025 | Environ Sci Technol
This study characterized legacy PFAS in serum from 700 California adults and examined contributions from diet and drinking water concluding that drinking water remains an important source of exposure to PFOA and PFHxS in this population.

Hair analysis as a non-invasive method for assessing the exposure of wildlife to per- and poly-fluoroalkyl substances (PFAS)
Science
13 May 2025 | Environ Pollut
By analyzing blood samples from 700 adults in southern and eastern California, scientists found that even low but detectable PFAS in local tap water significantly raised people’s levels of the legacy chemicals PFOA and PFHxS, while seafood and eggs contributed smaller amounts.

Transformation of polyfluoroalkyl precursors in AFFF-contaminated concrete
Science
10 May 2025 | Environ. Sci. Technol. Lett.
In AFFF‑soaked airport concrete, high‑pH conditions quickly break down PFAS precursors into mobile pollutants such as PFBA, PFHxA and PFOA, while most sulfonamide precursors stay locked in the slab—showing that runways can keep leaking PFAS long after foam use ends.

Diet quality in relation to serum perfluoroalkyl substance concentrations in Canadian preadolescents
Science
6 May 2025 | Environ Res
In Canadian preadolescents, higher dietary intake of fat, fiber, and iron was associated with increased blood concentrations of several PFAS—especially PFOS, PFDA, and PFHxS—suggesting that most diets may contribute to PFAS exposure through contaminated food systems.

Individual and mixtures of PFAS during pregnancy are associated with maternal cardiometabolic outcomes during pregnancy
Science
30 Apr 2025 | Environ Health
The majority of pregnant woman tested in central Arkansas had PFAS in her blood, and those with the highest levels showed shifts in cholesterol, triglycerides, resting pulse, and diastolic blood pressure— indicating potential harm to heart health during pregnancy.

USDA Finds Meat, Poultry, Farmed Catfish are PFAS-Free; but Detects PFAS in Half of Wild Catfish
News
28 Apr 2025 | Food Safety Magazine
The U.S. Department of Agriculture recently conducted exploratory sampling of meat, chicken, and catfish and tested them for 16 different types of PFAS, including PFOA and PFOS.

Hold my beer: The linkage between municipal water and brewing location on PFAS in popular beverages
Science
24 Apr 2025 | Environ. Sci. Technol.
A U.S. study of 23 popular beers shows that most contain PFAS, with higher levels directly tracing back to contamination in the local tap water used for brewing—sometimes above new federal limits—revealing that nearly one‑fifth of American breweries operate in PFAS‑affected areas and underscoring the need for tougher water treatment and regulation.

High serum perfluorooctanoic acid (PFOA) concentrations and interstitial lung disease in former and current workers in a fluorochemical company
Science
22 Apr 2025 | Ind Health
Former workers at a Japanese chemical plant who were exposed to dust containing high levels of PFOA, had much higher blood concentrations and a greater risk of lung disease even years after the plant stopped using PFAS, highlighting the need for long-term health monitoring.

Pilot study finds fiber helps reduce PFAS levels in the body
News
21 Mar 2025 | Environmental Health News
A Canadian clinical trial published in the journal Environmental Health, found some reductions of PFAS concentrations in people taking dietary fiber supplements for 4 weeks.

Leaching profile of per-and polyfluoroalkyl substances from selected e-waste components and potential exposure pathways from discarded components
Science
17 Mar 2025 | J Hazard Mater
Discarded electronics like cables, keyboards, monitors, and circuit boards can release harmful PFAS—especially PFBA, PFHxA, PFOA, and PFOS—into the environment through leaching, highlighting e-waste as a significant but underrecognized source of long-term contamination and exposure risks.

Ten years of PFOS and PFOA human biomonitoring in Italy: Exposure levels and determinants of exposure
Science
14 Mar 2025 | Chemosphere
PFAS exposure in the Italian population has declined over ten years for PFOA but not for PFOS, with higher levels observed in men, individuals in urbanized areas, and those with higher education or occupational skill levels, while proximity to PFAS-emitting industries remains the strongest predictor of elevated exposure.

Chemours to fund costly cleanup of PFAS-contaminated gardens in Dordrecht
News
10 Mar 2025 | Environmental Health News
Dozens of vegetable gardens near the Chemours factory in Dordrecht, the Netherlands are contaminated with PFOA, a type of PFAS, and cleaning them will cost between €25 million and €50 million, a cost the company has agreed to cover.

Per‐and polyfluoroalkyl substances in untreated and treated sludge/biosolids from 27 water resource recovery facilities across the United States and Canada
Science
9 Feb 2025 | Water Environ Res.
PFAS were detected in untreated and treated sludge biosolids from 27 water resource recovery facilities across the U.S. and Canada, with post-stabilized biosolids generally showing higher concentrations than pre-stabilized sludge, particularly for 5:3 FTCA and PFOS.
