摘　　要：五氯酚作为外源性内分泌干扰物对水生生物产生影响,试验研究五氯酚对大型溞蜕皮的影响。五氯酚浓度为1.0 mg/L时,试验组8只大型溞的7只的第三次、第四次和第五次蜕皮时间均延迟8 h,另外1只大型溞的这三次蜕皮时间推迟16 h(个体差异)。结果表明五氯酚通过干扰大型溞的内分泌系统,对大型溞蜕皮有抑制作用。Pentachlorophenol plays an effect on aquatic organism as environmental endocrine disruptors. The test studies the effect of pentachlorophenol on Daphnia magna＇s molting to research pentachlorophenol＇s function as endocrine disruptor（ environmental hormone）. Under 1. 0 mg / L pentachlorophenol,seven Daphnia magna＇s molting time is delayed 8 hours and one＇s molting time is delayed 16 hours on the third,the fourth and the fifth molting. Results demonstrate that pentachlorophenol inhibits Daphnia magna＇s molting by disrupting Daphnia magna＇s endocrine system.
