Abstract: Acute biotoxicity of tailings, As and Ca slags, Cr slags and electroplating sludges is studied with luminous bacteria method.The results show that luminous bacteria have a high sensitivity to the toxicity of tested solid wastes.The EC50 values of tested wastes are 2.54×10-6,1.07×10-4,2.14×10-4 and 3.62×10-4 respectively,being equivalent to the EC50 value(0.126μg·ml-1)of reference poison HgCl2.

Key words: Luminous bacteria method, Solid waste, Biotoxicity
