摘　　要：[目的]研究重金属Cd在文蛤体内的富集和消除规律及其食用安全性。[方法]将文蛤在Cd2+浓度为0、0.01、0.10、1.00、2.00mg/L试验海水中染毒。[结果]文蛤对Cd具有较强的富集能力。随着染毒时间的延长和Cd2+浓度的增加,Cd在文蛤体内的富集量也相应增加。[结论]文蛤内脏团中Cd的富集和代谢能力均大于闭壳肌,说明食用闭壳肌是安全的。[Objective] The research aimed to study accumulation and elimination of the heavy metal cadmium in Meretrix meretrix and the edible safety of M.meretrix.[Method] The cadmium concentration was designed as follows：0,0.01,0.10,1.00 and 2.00 mg/L,respectively.[Result] The experiment showed that M.meretrix had a high ability of accumulating cadmium.The higher the cadmium concentration was and the longer the period of experiment was lasting,the higher the cadmium concentration in M.meretrix was.[Conclusion] The gull＇ ability of accumulation and elimination of cadmium was higher than that of muscle.It is safe to eat muscle.
