Surface soil per- and polyfluoroalkyl substance mixtures dominated by perfluorooctane sulfonate: prioritization for ecotoxicity testing and ecological risk assessment at current and former U.S. Air Force bases
Science
7 Jan 2025 | Environ Toxicol Chem
PFAS mixtures in soil were dominated by PFOS (approximately 82%) but also included 5% to 12% of PFHxS, PFOA, PFOSA, and PFHxA. Additionally the study identified high concentrations but inconsistent prevalence of the 6:2 and 8:2 fluorotelomer sulfonates. These results highlight the need for toxicity testing of mixtures dominated by PFOS but including combinations of other PFAS.
