Résumé

Cadmium and zinc concentrations were determined in 10 species of pelagic zooplankton collected in the northern North Pacific, the Bering Sea, the Okhotsk Sea and off Hokkaidô, during the summers of 1974–1976. The mean cadmium contents in euphausiids, copepods, and amphipods were 1.16µg/g dry wt (range: 0.36–2.17µg/g), 6.63µg/g (1.66–14.55µg/g), and 8.28µg/g (2.83–14.50µg/g), respectively. Cadmium in euphausiids was significantly lower in concentration than in the other two crustacean groups. The difference in cadmium levels among the crustacean groups is discussed on the basis of feeding habits and physiological characteristics of the zooplankton. Zinc levels in the crustaceans were similar, with values around 100µg/g (range: 59–195?g/g). Both cadmium and zinc concentrations in euphausiids taken from coastal waters off Hokkaidô were significantly higher than those from the Bering Sea and the northern North Pacific. This trend may reflect coastal pollution rather than characteristics of the species.
