| Abstract: | Accumulation of cadmium, copper, lead and zinc in the tissues of Mytilus edulis planulatus was examined under cyclic conditions of exposure in order to establish whether the rate of accumulation of the metal is proportional to the time exposed to the elevated concentrations. When exposed to a single metal, the accumulation of lead and zinc was directly proportional to the exposure time, but that of copper was not. Under simultaneous exposure to all four metals both lead and cadmium were accumulated in direct proportion to the exposure time, while copper and zinc were not. Accumulation of the three metals cadmium, copper and zinc was influenced by the presence of other metals. |
