Prenatal exposure to a mixture of per- and polyfluoroalkyl substances (PFAS) and lung function and immune-related outcomes among males in childhood and young adulthood

2 Sep 2025 | Environ Res

Prenatal exposure to mixtures of PFAS was linked to reduced lung capacity in young adult males and a lower chance of hay fever in childhood, but showed no clear connection with asthma or eczema.

Detection and Quantitation of Per- and Polyfluoroalkyl Substances in North Carolina Sea Foam and the Corresponding Sea Water

27 Aug 2025 | Environ Sci Technol

Sea foam along the North Carolina coast contains extremely high levels of PFAS, sometimes millions of times above drinking water limits, making it a major reservoir of these harmful chemicals and a potential risk to people and ecosystems.

Co-occurrence behaviors of per- and polyfluoroalkyl substances (PFASs) and heavy metals in the groundwater of dyeing industrial sites in southern China

27 Aug 2025 | Ecotoxicol Environ Saf

Groundwater beneath long-operating dyeing industrial sites in southern China is heavily contaminated with both PFAS and toxic heavy metals, with concentrations varying by season and site, highlighting serious risks to water safety and the need for integrated pollution control.

Association between perfluoroalkyl and polyfluoroalkyl substances exposure and hypercholesterolemia among US adults: A cross-sectional study

25 Aug 2025 | Ecotoxicol Environ Saf.

Analysis of NHANES 2015–2018 data (n = 2,292) showed that higher serum levels of PFHxS, PFOA, and PFOS were significantly associated with increased prevalence of hypercholesterolemia, with PFHxS as the strongest contributor in mixture models, while combined PFAS exposure consistently elevated risk across multiple statistical approaches.

Recent advances in the detection of per-and polyfluoroalkyl substances (PFAS) in food: A review of optical sensors, electrochemical sensors, and biosensor

25 Aug 2025 | Trends in Food Science & Technology

Nanomaterial-based optical sensors, electrochemical techniques such as voltammetry and impedance spectroscopy, and biosensors were found to be able to detect PFAS in food at trace levels from parts per million down to parts per trillion, allowing faster, portable, and more selective alternatives to chromatography and mass spectrometry.

Integrating ultrashort-chain compounds into the comprehensive analysis of per- and polyfluorinated substances in ready-to-feed liquid milk samples

25 Aug 2025 | Journal of Chromatography Open

Across the 24 American milk samples tested, PFAS were found in every type, including dairy, plant-based, and infant formula, with ultrashort-chain compounds like trifluoroacetic acid, trifluoromethanesulfonic acid, and short-chain PFAS such as PFBA and PFHpA being the most widespread.

The landscape of PFAS contamination in the United States: sources and spatial patterns

24 Aug 2025 | Environ. Sci. Technol.

PFAS contamination is widespread across the United States, with groundwater detections exceeding health limits at nearly all tested sites, especially around military bases, airports, and firefighting foam users, while industrial and waste facilities account for most likely sources and drive regional hotspots that raise major water safety and environmental justice concerns.

Mitigating PFAS contamination in the United States: Assessing the impact of California’s legislation from 2018 to 2022 on drinking water quality

23 Aug 2025 | JPHP

California’s 2018–2022 PFAS laws helped cut PFOA and PFOS levels in drinking water by more than half, showing that strong state policies can significantly reduce contamination and serve as a model for national action.

Associations between per- and polyfluoroalkyl substances and type 2 diabetes: The modifying effects of lifestyle and genetic risk

23 Aug 2025 | J Hazard Mater

Certain PFAS chemicals (like PFOA, PFNA, PFBA, and PFHpA) are linked to a higher risk of type 2 diabetes and these effects are made stronger by lifestyle choices and high genetic risk.

Backward and historical PFOA exposure estimation in an adult population highly exposed in the Veneto region

22 Aug 2025 | Environments

People in Italy’s Veneto region were exposed to far higher levels of PFOA in their blood than later testing showed, with modeled peak concentrations more than double the measured values.

Socioeconomic disparities and risk of papillary thyroid cancer associated with environmental exposure to per-and polyfluoroalkyl substances (PFAS) in Florida

18 Aug 2025 | IJERPH

Residential proximity to PFAS-contaminated sites in Florida was linked to higher papillary thyroid cancer incidence among non-Hispanic White and Hispanic populations, with lower-income communities facing disproportionately greater exposure.

Building collision fatalities for monitoring per-and polyfluorinated alkyl substances (PFAS) in wild bird populations

18 Aug 2025 | Environ. Sci. Technol. Lett.

Wild birds killed in building collisions in Chicago, were found to carry PFAS levels similar to those in free-living populations, with long-chain PFAS like PFOS and PFCAs most common, making collision sampling a useful tool for monitoring environmental contamination.
