Abstract: OBJECTIVE: To explore the environmental risk of butachlor on aquatic organisms. METHODS: 0.4,0.8 and 1.2 mL/L concentrations of butachlor were prepared according to 24 h-LC50. Carassius auratus were administered by intraperitoneal injection with 0.1 mL/g dose of each concentration for 24 h. PAGE method was used to detect the activity of EST and POD isozyme. RESULTS: EST and POD isozyme in the hearts of C. auratus were not expressed in the control group but was more than 50 times (in 1.2 mL/L) that of the control group. With increased concentrations of butachlor,the activity of EST isozyme in hepatopancreas gradient attenuated while the POD decreased followed by increased. The activities of EST isoenzymes in gill and kidney were 2 times and 3 times higher than those in the control group at 0.4 mL/L,respectively. In addition,the activities of EST and POD isoenzymes in gill and kidney disappeared at 0.8 mL/L and re-expressed at 1.2 mL/L. CONCLUSION: The concentration of butachlor and the activity of EST and POD isozyme in C. auratus show dose-effect relationship. Butachlor with medium concentration (0.8 mL/L) was at risk for EST and POD isozyme in gill and kidney of C. auratus.
