As much as 89,176 and 292 mg Cd per kg dry weights were accumulated by adult Crassostrea virginica after treatment for 40 wk with 5, 10 and 15 mg Cd per kg, respectively, in flowing seawater at ambient salinity and temperature without mortalities. Cadmium accumulation increased with increased concentrations of cadmium in seawater; greater amounts were accumulated during the summer months. At seawater temperature below 6C cadmium concentrations in the total soft parts varied significantly between treatments, but not within treatments. Cadmium concentration in the total soft parts varied inversely with dry weight, whereas cadmium content varied directly.
