Abstract: Cd2 general exist in pharmaceutical wastewater, even if low dose Cd2 expose in environment can cause renal dysfunction , bone mineral density reduce, excretion of calcium increase and genotoxicity, ecological entironment deterioration caused by Cd2 draw the attention of various countries in the world. This paper acquired the theoretical value of semi-lethal concentration (LC50) of 24 hours was 0.471 mg/L. We chose 5 concentration of Cd2 between 0.415mg/L and 0.535mg/L to disposed Limnodilus claparedianu 24 h, examed the variation of L.claparedianus superoxide dismutase(SOD) and peroxidase(POD) activity. The result demonstrated that stressed at different of Cd2 concentration, the activity of SOD and POD of L.claparedianus all have changed, but the continuous change trend of tow enzyme are opposite. It showed that these tow enzyme has different biological mechanism , it meybe play different role in the project of cell resistance the foreign pollutant.
