The marine mollusc Venus gallina was exposed to 32 days sublethal concentrations of Cadmium (0.1 microliter/ml). The activity of alkaline phosphatase was assayed every four days. In the controls the activity was also tested in different tissues and in the soft tissue for the pH dependence. Moreover the influence of direct addition of 10(-4) M Cd on enzyme preparation in vitro was assayed. From the results there are no consistent relationships between the direct in vitro effects of the metal on the enzyme, that is inhibitory, and the effect of exposing the whole animal to the same metal, in this case no inhibition was observed.
