摘要
为了估测农药毒死蜱的环境毒性,以大鳞副泥鳅(Paramisgurnus dabryanus)为受试动物,研究毒死蜱对大鳞副泥鳅的急性毒性和生理毒性作用。研究结果表明,毒死蜱稀释液对大鳞副泥鳅的24、48、96 h的半数致死浓度(LC50)分别为524.76、291.53、193.20μg/L,安全浓度为26.99μg/L;对照组肝组织谷丙转氨酶(GPT)和谷草转氨酶(GOT)的平均活力分别为24.53 U/g和16.69 U/g;试验组肝组织的GPT和GOT活力最低分别可达到2.65 U/g和2.81 U/g。毒死蜱对大鳞副泥鳅具有明显的急性毒性和生理毒性效应,并表现出明显的剂量-时间效应。
To evaluate the environmental toxicity of chlorpyrifos, using Paramisgurnus dabryanus as the tested animal, the a- cute toxicity and physiology toxicity of chlorpyrifos to Paramisgurnus dabryanus were studied. The results showed that the 24 h,48 h and 96 h LC50 of chlorpyrifos diluent were 524.76 μg/L,291.53 μg/L and 193.20 μg/L, respectively, safety concentra- tion was 26.99μg/L. The activities of glutamic pyruvic transaminase （GPT） and glutamic oxaloacetic transaminase （GOT） of the control group were 24.53 U/g and 16.69 U/g respectively, and the lowest activities of GPT and GOT in liver tissue of experimental group were 2.65 U/g and 2.81 U/g respectively. Chlorpyrifos had significant acute toxicity and physiological toxic- ity effect to Paramisgurnus daloryanus, and showed significant dose-time effect.
