東部ベーリング海産数類カレイ類のPCB含量について

抄録

Materials used for the present study of polychlorinated biphenyls (PCB) concentrations in the muscle, liver and egg of four species of flatfish were collected from 14 locations in the Eastern Bering Sea. Analysis proved that PCB concentrations in muscle ranged between 0.02-0.13 ppm with distinct differences within the same species depending on the source location. PCB contents in liver samples ranged from 0.06-0.27 ppm, i, e., always higher than the muscle values, and egg PCB contents were 0.01-0.03 ppm, i, e., lower than muscle levels.
