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.

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