Abstract：In order to explore the dose-response relationship between the carbendazim mass con-centration and antioxidant enzyme activities of earthworms ,and to accumulate data for exploring the safe use of carbendazim ,the changes of antioxidant enzyme activities of earthworms after acute exposure to carbendazim were determined .The experimental results showed that the re-sponse of superoxide dismutase (SOD) ,peroxidase (POD) ,and glutathione peroxidase (GSH-Px) in earthworms to carbendazim was different 48 h after acute exposure .Compared with the control group ,the certain low mass concentration of carbendazim had an inhibition effect on GSH-Px ac-tivity .However ,with the increase of the mass concentration of carbendazim ,it had a promotion on GSH-Px activity ,but the promotion of high mass concentration was lower than the low mass con-centration .Different concentrations of carbendazim all promoted SOD activity ,and the promotion of high mass concentration was lower than the low mass concentration .Except that the certain mass concentration of carbendazim (1 .25 g/L ) induced POD activity ,carbendazim had an inhibi-tion effect on POD ,and the inhibitory effect of high concentration was stronger than the low con-centration .Besides ,SOD was sensitive to the influence of carbendazim ,followed by GSH Px ,and POD w as w eakest .
