PCB and DDT in blubber of cetaceans from the northeastern north Atlantic

摘要: Abstract Blubber from long-finned pilot whales, Atlantic white-sided dolphins and harbour porpoises caught off the Faroe Islands, fin sei sperm whales Iceland were analysed for organochlorine pollutants. Pollutant levels positively correlated with increasing trophic level inversely body size. For any given species, %DDE/Σp,p′-DDT ratio increased Σp,p′-DDT burden, probably reflecting detoxification activity of liver enzymes at higher contaminant concentrations. The %Σp,p′-DDT/PCB decreased suggesting differential transfer rates two groups through food webs. Because effect organochlorines gestation lactation, PCB levels, ratios in males than females.
