4种重金属盐对泥东风螺幼螺的急性毒性试验
Acute Toxicity Tests of Four Heavy Metal Salts to Juvenile Snail of Babylonia lutosa
摘要
Abstract
The acute toxicity of four heavy metals [CuSO4 · 5H2O、ZnSO4 · 7H2O、 CdCl2 and Pb (NO3)2] 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 · 7H2 O 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+.关键词
