Description
Summary:•Accumulation patterns and metabolic capacities among three Phocoenidae cetaceans.•Three porpoise species had variations in OH-PCBs accumulation features.•Porpoises have the lowest PCBs metabolic capacities compared with any other animals. The present study investigated polychlorinated biphenyls (PCBs) and hydroxylated metabolites of PCBs (OH-PCBs) in blood from three porpoise species: finless porpoises (Neophocaena phocaenoides), harbor porpoises (Phocoena phocoena), and Dall’s porpoises (Phocoenoides dalli). The porpoises were found stranded or were bycaught along the Japanese coast. Concentrations of OH-PCB were the highest in Dall’s porpoises (58pgg−1 wet wt), second highest in finless porpoises (20pgg−1 wet wt), and lowest in harbor porpoises (8.3pgg−1 wet wt). The concentrations in Dall’s porpoises were significantly higher than the concentrations in finless porpoises and harbor porpoises (p
