摘　　要：以大鳞副泥鳅(Paramisgurnus dabryanus)为受试动物,研究高效氯氟氰菊酯对大鳞副泥鳅的急性毒性和遗传毒性,从而正确估测高效氯氟氰菊酯对水生动物的毒性。结果表明,高效氯氟氰菊酯对大鳞副泥鳅24、48、72、96 h的半数致死浓度(LC50)分别为25.93、17.28、15.31、14.11μg/L,安全浓度为2.3μg/L。遗传毒性试验中,处理组的微核率和核异常率均高于对照组,且与染毒浓度和时间呈正相关,高效氯氟氰菊酯对大鳞副泥鳅有很强的诱变性。With Paramisgurnus dabryanus as tested animal, experiments on acute toxicity and genetic toxicity of lambda-cy- lmlothrin were performed to correct estimation of lambda-cyhalothrin on aquatic animal toxicity. The results showed that the LC50 （24,48,72 and 96 h） of lambda-cyhalothrin were 25.93,17.28,15.31 and 14.11 μg/L respectively, safety concentration was 2.30 μg/L. The micronucleus rates and nuclear anomalies rates of treatment group were higher than those in control group in genetic toxicity experiment, and manifested positive correlation to the test time and test dose of lambda-cyhalothrin lambda-cyhalothrin, it showed that lambda-eyhalothrin had very strong mutagens on P. dabryanus.
