Abstract
Various forms of regression analysis are presented which show that there is a significant equilibrium relationship between total recoverable cadmium in seawater and its concentration in the mussel Mytilus edulis (P<0.001). The calculations show that the concentration of cadmium in seawater should not exceed 0.20 μg l-1 if the mussel is not to reach a cadmium concentration of 2 mg kg-1 wet weight: a value frequently used as a food standard for human consumption. Further, when a cadmium value of 2 mg kg-1 wet weight is reached, the concentration factor by mussels for cadmium from seawater is 9 950.
