摘要
为了估测高效氯氟氰菊酯对水生生物毒性的大小,以大鳞副泥鳅作为受试动物,研究不同浓度的高效氯氟氰菊酯对其急性毒性和生理毒性的影响。结果表明:高效氯氟氰菊酯对大鳞副泥鳅24h、48h、96h的半数致死浓度(LC50)分别为25.93μg/L、17.28μg/L、14.11μg/L,安全浓度为2.30μg/L。低浓度高效氯氟氰菊酯对大鳞副泥鳅肝脏谷丙转氨酶(GPT)和谷草转氨酶(GOT)起诱导作用,高浓度对其起抑制作用,试验组与对照组存在显著或极显著差异。研究表明,高效氯氟氰菊酯对大鳞副泥鳅有较强的毒性。
In order to assess the toxicity of lambda-cyhalothrin on aquatic animal, the acute and physiological toxicity of lambda-cyhalothrin in Paramisgurnus dabryanus were determined. The results showed that the LCso （24 h, 48 h and 96 h） of lambda-cyhalothrin were 25.93μg/L, 17.28 μg/L and 14. 11 txg/L, respectively, and the safety concentration was 2.30 μg/L. The activities of GPT and GOT in liver were induced by the lower concentration treatments of lambda-cyhalo- thrin, but could be restrained by the higher concentration treatments. Experimental groups were significant difference with the control group. In conclusion, lambda-cyhalothrin has a strong toxicity to Paramisgurnus dabryanus.
