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.

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.

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.
