Abstract:To investigate the effects of linear alkylbenzene sulfonates(LAS) and Cd2+ single and combined pollution in Rana limnocharis tadpole,the acute toxicity and joint toxicity tests of LAS,Cd2+ and the activities of superoxide dismutase(SOD) and catalase(CAT) in liver were measured by using exposed experiment.The results showed that LC50 of 96 h for LAS and Cd2+ to tadpole were 14.43 mg/L,4.21 mg/L respectively.In addition,it also indicated that the joint toxicity of Cd2+ and LAS was synergistic while the toxici...
