Abstract

This study deals with the acute toxicity of Cu 2+, Zn 2+, Cd 2+, Cr(Ⅵ) and joint toxicity of Cu 2+, Zn 2+, Cd 2+, Cr(Ⅵ) to M.rosenbergii. The median lethal concentrations of these four heavy metals to M.rosenbergii are 0.462mg/L, 0.580mg/L, 0.015mg/L and 0.114mg/L. The order of the toxicity of these four heavy metals is obtained as follows : Cd 2+ Cr(Ⅵ)Cu 2+Zn 2+; Cu 2+ and Zn 2+, Zn 2+ and Cd 2+ are antagonism; Cu 2+ and Cd 2+, Cu 2+ and Cr(Ⅵ), Zn 2+ and Cr(Ⅵ) are synergism.
