The acute toxicity of four heavy metals to juvenile snails of Babylonia lutosa were studied at water temperature 16-23℃, salinity 30 and pH 8.0. The results showed that the LC50 values of CuSO4·5H2O treatment for 24h, 48h, 72h and 96h were 2.596, 1.037, 0.690 and 0.400 mg·L-1, respectively. The LC50 values of ZnSO4·7H2O treatment for 24 h, 48 h, 72 h and 96h were 16.384, 4.738, 3.225 and 2.721 mg·L-1 respectively. The LC50 values of CdCl2 treatment for 24 h, 48 h, 72 h and 96h were 17.286, 7.340, 3.799 and 2.361 mg·L-1 respectively. The LC50 values of Pb(NO3)2 treatment for 24h, 48h, 72h and 96h were 650.640, 410.595, 262.342 and 141.525mg·L-1 respectively. The safe concentration of four heavy meals to juvenile snails of B. lutosa were 0.040, 0.272, 0.236 and 14.153 mg·L-1 respectively.The safe concentration of four heavy metals ions to juvenile snails of B.lutosa were 0.010,0.062,0.148 and 8.501 mg·L-1 respectively.The toxicity was in the order of Cu2+>Zn2+>Cd2+>Pb2+.
