摘 要: | [目的]比较5种药剂对大型溞(Daphnia magna Straus)的急性活动抑制毒性。[方法]测定了5种药剂对大型溞的急性活动抑制中浓度EC50,并评价了5种药剂对大型溞的毒性。[结果]5种药剂对大型溞的毒性大小表现为:20%甲氰菊酯水乳剂(EC50=0.002 8a.i.mg/L)10%高效氯氟氰菊酯可湿性粉剂(EC50=0.008 9 a.i.mg/L)7.5%鱼藤酮乳油(EC50=0.189 9 a.i.mg/L)7.5%除虫菊素水乳剂(EC50=0.202 0 a.i.mg/L)0.5%大黄素甲醚水剂(EC50=0.640 1 a.i.mg/L)。[结论]为大型溞应用于环境污染监测研究提供了理论依据。

Abstract: | [Objective] The aim was to compare the acute immobilization toxicities of five pesticides to Daphnia magna Straus.[Method] The EC50 values of five pesticides to D.magna were determined,and then the acute immobilization toxicities of five pesticides to D.magna were evaluated.[Result] The acute immobilization toxicities of five pesticides to D.magna were as follows: 20% fenpropathrin EW(EC50= 0.002 8 a.i.mg/L)>10% cyhalothrin WP(EC50= 0.008 9 a.i.mg/L) > 7.5% rotenone EC(EC50= 0.189 9 a.i.mg/L) > 7.5% pyrethrins EW(EC50= 0.202 0 a.i.mg/L)>0.5% physcion AS(EC50= 0.640 1 a.i.mg/L).[Conclusion] The result lays theoretical basis for the application of D.magna in environmental pollution monitoring. |
