Abstract:
The concentration of some heavy metals was investigated in Dianchi lake water and a clam A.woodiana elliptica.The results show that,in Dianchi lake water,the concentrations of Cu,Pb and Zn reach to 3.198,0.412μg/L and 0.0205μg/L respectively.In the clam bred in Dianchi lake,the concentrations of Cu,Pb,Zn and Fe reach to 9.04,35.68,7.08×102mg/kg and 4.74×103mg/kg respectively.Being compared with the concentrations in Dianchi lake water,the clam shows great accumulation capacity of Cu,Pb,and Zn.
