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

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

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

PFAS Exposure and Postoperative Weight Regain in Adolescents After Bariatric Surgery: Findings From the Teen-LABS Study
Science
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.

Multi-site study of communities with PFAS-contaminated drinking water: Methods, demographics, and PFAS serum concentrations
Science
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
Science
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
Science
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
Science
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.

Pygoscelis penguins as indicators of perfluoroalkyl substances pollution and global health risks - case study from King George Island (Western Antarctic)
Science
29 Jul 2025 | Environ Res
Scientists found that guano from penguins nesting near research stations on King George Island contained detectable PFAS chemicals (PFOS and PFPeS) while colonies farther away did not, revealing that even remote Antarctic wildlife is affected by localized human pollution.

Occurrence and maternal transfer of per-and polyfluoroalkyl substances (PFAS) in pregnant sharks from Florida coastal waters
Science
17 Jul 2025 | Environ. Sci. Technol.
PFAS chemicals were found in pregnant sharks from Florida waters and shown to pass from mothers to their 101 developing embryos during gestation, with longer chain types such as PFOS building up the most in embryo tissues.

Occurrence and tissue distribution of per- and polyfluoroalkyl substances (PFAS) in fishes from waterbodies with point and non-point sources in Massachusetts, USA
Science
17 Jul 2025 | Aquat Toxicol
In Massachusetts lakes and rivers, fish near known PFAS sources had much higher PFAS levels, especially PFOS. PFAS levels rose between 2020 and 2022, concentrating in blood more than in liver or muscle, and with lab tests showing signs of inflammation and other stress.
