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.
Per-and polyfluoroalkyl substances (PFAS) and microRNA: An epigenome-wide association study in firefighters
15 Aug 2025 | Environmental Research
In U.S. firefighters, higher blood levels of certain PFAS chemicals were linked to changes in microRNA expression patterns associated with increased risks for various cancers, neurological disorders, and autoimmune diseases.
PFAS Exposure and Postoperative Weight Regain in Adolescents After Bariatric Surgery: Findings From the Teen-LABS Study
14 Aug 2025 | Obesity (Silver Spring)
Adolescents with higher pre-surgery blood levels of certain PFAS chemicals were more likely to regain weight and waist size in the years after bariatric surgery, potentially reducing the procedure’s long-term health benefits.
PFAS contamination and its rising toll on food security: A hidden global threat
11 Aug 2025 | Food Control
Widespread PFAS contamination from industrial, agricultural, and packaging sources has been found to accumulate in global food systems, compromising food safety, disrupting ecosystems, and posing significant long-term health risks.
Per-and polyfluoroalkyl substances on the surface of children's feeding smocks: High-throughput characterization and implications for exposure assessment
11 Aug 2025
Elevated PFAS levels were detected on Chinese children’s feeding smocks, making routine hand-to-mouth contact during use a potential exposure at levels on par with everyday exposure from indoor dust and air.
Multi-site study of communities with PFAS-contaminated drinking water: Methods, demographics, and PFAS serum concentrations
11 Aug 2025 | Environ. Int.
In eight PFAS-affected U.S. communities, blood tests of 5,826 adults and 710 children from 2019 to 2023 found higher PFHxS and PFOA in adults and higher PFHxS only in children.
Serum Levels of Per- and Polyfluoroalkyl Substances in Adults Aged 18 and Older in Relation to the Length of Residency in United States
11 Aug 2025 | J Immigr Minor Health
Immigrants to the U.S. tend to have lower levels of PFAS such as PFOA, PFOS, PFHxS, PFNA, and PFDeA upon arrival, but their levels increase over time, often matching those of U.S.-born people within 5 to 15 years, depending on race, ethnicity, and differences in past and ongoing environmental exposures.
Assessing the shifts in atmospheric per-and polyfluoroalkyl substances (PFAS) levels in the Great Lakes and implications for the environmental transport and fate
7 Aug 2025 | ACS ES&T Air
Levels of PFAS, including PFOA, PFOS, and other related chemicals, in the Great Lakes atmosphere have declined in recent years due to regulations and manufacturing changes, however some newer PFAS are increasing, showing the need for ongoing monitoring and control efforts.
PFAS in rural U.S. well water: Using participatory science to identify and communicate results to address risks
7 Aug 2025 | Environ. Sci. Technol.
PFAS were found in rural U.S. private wells, most often PFOA, PFOS, and PFHxS, with some exceeding the U.S. EPA’s 2023 drinking water limits even in areas with no known sources.
