| Abstract: | The joint toxicity of copper and cadmium to tadpole is studied in acute tests.The results show that the LC50 of Cu2 ' to tadpole is 0.201 mg/kg,0.138mg/kg and 0.118 mg/kg in 24h,48h and 96h,respectively;and the LC50 of Cd2 to tadpole is 32.1 mg/kg,23.3mg/kg and 18.9mg/kg in 24h,48h and 96h,respectively.According to the addictive index method of marking,the addictive index (AI) of Cu2 and Cd2 to tadpole is 1.03,1.12 and 1.20 in 24h,48h and 96h,respectively.The results show synergism action. |
