Occurrence of perfluorooctane sulfonate and other perfluorinated alkylated substances in harbour porpoises from the Black Sea
Perfluorooctane sulfonate (PFOS) and other perfluorinated alkylated substances (PFAS) were determined in liver, kidney, muscle, brain, and blubber samples of 31 harbor porpoises ( Phocoena phocoena relicta ) of different age and sex stranded along the Ukrainian coast of the Black Sea. In all individ...
