Abstract

type:P(論文)

DDTs (p, p'-DDE+p, p'-DDT) and polychlorinated biphenyls (PCBs) were determined in the liver of male minke whales collected from the Southern Ocean during the 1980-1981 whaling season. DDTs ranged from 3.6 to 70ng/g and PCBs from 1.2 to 18ng/g on lipid weight basis. These values were apparently lower than those in northern baleen whales and also in southern toothed whales. This seems to be attributable to the smaller extent of contamination by these pollutants in the southern hemisphere and the habits of minke whales feeding on lower trophic organisms, primarily eupausiids, in the Antarctic ecosystem. Considerably high concentrations of DDTs and PCBs were found in young minke whales and a continuous increase of these was observed in older animals after approximately 20 years of age. These trends probably arise from feeding habits of minke whales associated with migration and segregation in age groups of young and old.
