Occurrence of 80 Per and polyfluorinated alkyl substances (PFAS) in the Muscle and Liver tissues of Marine Mammals of the St. Lawrence Estuary and Gulf, Quebec, Canada
Science
10 Jun 2024 | Front. Environ. Chem.
Marine mammals from the St. Lawrence Estuary and Gulf, such as dolphins and porpoises, were found to have high levels of PFAS in their tissues, with the white-sided dolphin showing the highest average concentrations—39 ng/g in muscle and 334 ng/g in liver—while species like the harp seal had much lower levels, emphasizing the need for stronger regulations to protect these vulnerable animals.
