摘要	This research aimed to investigate the accumulation of Cadmium (Cd) and the antioxidant defense system (Superoxide Dismutase (SOD), Catalase (CAT) and Glutathione Peroxidase (GPx)) in gill and digestive gland of Mizuhopecten yessoensis exposed to Cd (final Cd doses of 0, 0.05, 0.1 and 0.2 mg L-1) for 14 days. The uptake of Cd in both tissues via seawater displayed a simple linear relationship with the exposure of Cd concentration and a curvilinear change with time of extending. The maximal accumulation was observed at day 10 in gill in the 0.2 mg L-1 group (134.20 mu g g(-1)) and day 14 in digestive gland in the 0.1 mg L-1 group (109.20 mu g g(-1)). The activities of SOD, CAT and GPx attained peak values after short exposure time at day 1 or 3 (except for CAT values in digestive gland and GPx value in gill in low Cd concentration). The main antioxidant enzyme in M. yessoensis is GPx in gill but CAT in digestive gland and the main detoxification tissue dealing with oxyradicals is digestive gland. These results provide valuable information of Cd accumulation and antioxidant defense mechanism in cadmium-stressed M. yessoensis and SOD, CAT, GPx could be useful as biomarkers in predicting heavy metal pollution in scallop aquaculture.; This research aimed to investigate the accumulation of Cadmium (Cd) and the antioxidant defense system (Superoxide Dismutase (SOD), Catalase (CAT) and Glutathione Peroxidase (GPx)) in gill and digestive gland of Mizuhopecten yessoensis exposed to Cd (final Cd doses of 0, 0.05, 0.1 and 0.2 mg L-1) for 14 days.
