摘　　要：通过对嫩江几种蚌类不同部位重金属残毒分析，得出３种蚌类中背角无齿蚌的富集能力最强，不同部位中，足对总汞的富集能力最强，外套膜对镉的富集能力最强，面鳃对铅、铜、锌富集能力最强．We have analysed heavy metal concentration in eachorgan of Cristartia plicata, Anodonta woodiana and Uniodouglasiae in Nenjiang river, Qiqihar.It is found that the accumulation of Anodonata woodiana is the highest;Thefoot has a high accumulation for total Hg,While outcovered membrane for Cd,Gill for Pb Cu,Zn.
