Abstract

In this study, accumulation of copper, zinc and cadmium at varying concentrations from sea water and sediment under the laboratory conditions was assessed by bioaccumulation tests, using the marine crustacean Corophium volutator (Pallas). Concentrations of these metals in the whole tissues of C. volutator were determined at intervals of 3, 6, 24, 48, 72 and 96 h. There is positive correlation between metal levels in C. volutator and metal levels in sea water and sediment. The results also show that the accumulation of copper, zinc and cadmium in C. volutator from the sea water is higher than those from sediment.
