4种重金属对克氏原螯虾的急性毒性研究
Study on the Acute Toxicity of 4 Kinds of Heavy Metals to Procambarus clarkii
摘要
Abstract
[Objective] The research aimed to study the acute toxicity of 4 kinds of heavy metals to Porcamharus clarkii. [ Method]Using stagno-phile test method,the median lethal concentration (Z.C50)and safe concentration (SC) of 24,48,72and 96 h of heavy metals(Cd,Cu,Zn and Pb) to P. clarkii were studied. [Result] The mortality of P. clarkii increased with the increase of heavy metals' concentration, showing an obvious dose - effect relationship. The acute toxicity of 4 kinds of heavy metals to P. clarkii was as follows: Cd > Cu > Zn > Pb. According to classification standards of toxic chemicals,Cd and Cu were middle toxicant to P. clarkii,and their SC values were 0. 037 4 and 0. 052 8 mg/L respectively, which were all higher than the standard of fishery water quality. Zn and Pb were low toxicant to and their SC values were 0. 220 9 and 0. 753 8 mg/L respectively. 96 joint test showed that the toxicity of (Cu + Pb) to P. clarkii showed a synergistic effect. [ Conclusion ] P. clarkii showed high tolerance to these four kinds of heavy metals.关键词
