Cu2+和Pb2+对石蚕蛾幼虫的急毒性研究
Acute Toxicity of Cu2+and Pb2+ on Stenopsyche marmorata Larvae
摘要
Abstract
[Objective] To study the acute toxicity effects and safe concentration of Cu2+ and Pb2+ on Stenopsyche marmorata larvae.[Method] S.marmorata larvae were collected from the stream of Shiwan Mountains.Acute toxicity test of Cu2+ and Pb2+ ions were carried out by using the hydrostatic toxicity test method.[Result] Using probit method,LC50 of Cu2+ and Pb2+ on S.marmorata larvae at 24,48,72 and 96 h were calculated as 123.651, 112.975, 84.536, 70.509 mg/L and 49.138,41.878,30.735,29.245 mg/L, respectively.The safety concentrations of Cu2+and Pb2+ on S.marmorata larvae were 7.051 mg/L and 2.925 mg/L, respectively.[Conclusion] The research results can provide scientific basis for S.marmorata larvae as a biological indicator for monitoring heavy metal pollution.关键词
