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.
