PFAS accumulation and effects in juvenile ospreys (Pandion haliaetus) from Chesapeake and Delaware Bays

Per- and polyfluoroalkyl substances (PFAS) are a class of ubiquitous, environmentally persistent compounds that pose a threat to human and wildlife health. Ospreys (Pandion halieatus) are a model avian species with a documented history of serving as effective bioindicators of contamination. Our study aims to provide a more thorough understanding of PFAS presence in the Chesapeake and Delaware Bays, as well as how PFAS exposure may be associated with health impacts in raptors.
