摘　　要：[目的]评价97%氰氟草酯原药对斑马鱼的急性毒性和生物富集效应。[方法]参考《化学农药环境安全评价试验准则》,测定97%氰氟草酯原药对斑马鱼的急性毒性和生物富集效应,计算半效应浓度LC_(50)和生物富集系数BCF。[结果]97%氰氟草酯原药对斑马鱼急性毒性为中毒,生物富集等级属于中等富集性。[结论]在实际应用过程中,氰氟草酯应严格控制其用量,尽可能减少对斑马鱼和水生生态系统的危害。[Objective]To evaluate the acute toxicity and bioenrichment effects of 97%cyhalofop-butyl on Brachydanio rerio.[Method]The acute toxicity and bioaccumulation effect of 97%cyhalofop-butyl on Brachydanio rerio were determined.The median effective concentration LC_(50) and bioconcentration factor BCF were calculated by reference to Test Guidelines on Environmental Safety Assessment for Chemical Pesticides.[Result]The acute toxicity of 97%cyhalofop-butyl on Brachydanio rerio was middle toxic;cyhalofop-butyl was a kind of medium bioconcentration pesticide.[Conclusion]The cyhalofop-butyl should be strictly controlled to minimize the damage to zebrafish and aquatic ecosystem.
