摘要
为探讨低毒除草剂对水生生物的危害,用急性染毒法研究了0.125,0.250,0.500,1.000,2.000μL/L 5个浓度组的乙草胺处理液在24,48,96 h对泥鳅肝脏超氧化物歧化酶(SOD)活性的影响.结果表明,在24和48 h,处理液对泥鳅的半数致死浓度分别为4.7和4.4μL/L.不同浓度的乙草胺处理对泥鳅肝脏中SOD活性都具有诱导作用,因此可以用泥鳅肝脏中SOD活性变化作为水环境监测的生物学指标来评价水生生物的生态环境.
To explore the harm of low poisonous herbicide on creature from water,5 kinds of different concentrations of aeetochlor such as 0. 125,0. 250,0. 500,1. 000,2. 000 μL/L were administrated to the adduh Misgurnus anguillicaudatus for 24,48,96h, respectively. The results showed that the concentrations of acetochlor on 24h - LC50 and 48h - LC50 of loach were 4.7,4.4 μL/L, and all concentrations of aeetochlor enhanced the activity of SOD . The activity change of SOD in liver of loach can be used as a biological indicator to evaluate the aquatic ecosystem.
