Perfluoroalkyl acid depuration from the edible tissues of a migratory recreationally fished species

Environmental emissions of perfluoroalkyl acids (PFAAs) impact estuarine species and the fisheries that rely on them. Migratory estuarine fishes may be captured for consumption in areas distant to known contaminant sources, but exposure risk depends on how quickly contaminants are depurated. This ba...

Zusammenfassung:Environmental emissions of perfluoroalkyl acids (PFAAs) impact estuarine species and the fisheries that rely on them. Migratory estuarine fishes may be captured for consumption in areas distant to known contaminant sources, but exposure risk depends on how quickly contaminants are depurated. This baseline presents the outcomes from a novel experiment simulating the migration of a popular recreational fish species (Dusky Flathead, Platycephalus fuscus) following environmental exposure to PFAAs, and assessing depuration from edible muscle tissues. Over the 33-day experiment, perfluorooctane sulfonate (PFOS) concentrations declined slowly, with modelling suggesting that concentrations fell below the relevant screening value (5.2 μg kg−1) within ∼558 h (285–1372 h; 90 % CI). Low concentrations (
