摘要：

1. Studies were performed regarding the effects of cadmium and copper on the lipid peroxide contents and on the initial rates of NADPH-dependent and Fe-ascorbic acid-dependent lipid peroxidation in the microsomes of hepatopancreas of the scallop Mizuhopecten yessoensis exposed to these pollutants for 3 weeks. 2. The results demonstrated that copper accumulation in hepatopancreas cells was accompanied by a significant increase in hydroperoxide and malondialdehyde contents in microsomal membranes, and by alteration in the both enzymic and non-enzymic lipid peroxidation. Cadmium didn't appear to potentiate lipid peroxidation processes in mollusc tissues. 3. Possible reasons for different effects of these metals on lipid peroxidation processes are discussed.
