Concentrations of polychlorinated biphenyls (PCB) were determined in the muscle of 36 species of marine animals collected in the sea near Hakodate in 1973-1975. Analysis proved that PCB concentrations in the muscle ranged between 0.01-0.18ppm, i. e., a maximum value of 0.18ppm in Tribolodon hakonensis hakonensis, and a minimum value of 0.01 ppm in Osmerus dentex. The muscle PCB contents were high in proportion to the high fat contents in the species of Tribolodon hakonensis hakonensis, Sardinops melanosticta, Trachurus japonicus, and Pleurogrammus azonus with the exception of Pneumatophorus japonicus japonicus and Astroconger mvriaster. On the contrary, PCB contents were generally low in proportion to the low fat contents in 26 species of fish with the exception of Paralichthys olivaceus, Fugu vermicularis porphyreus, Kareius bicoloratus, and Hexagrammos otakii. Consequently, the level of PCB concentrations in the muscle of fish in this area was found to be extremely low as compared with that in fish in other polluted areas, i. e., the Inland sea of Japan and Tokyo Bay.
