Abstract:

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 LC50 (24 h, 48 h and 96 h) of lambda-cyhalothrin were 25.93 μg/L, 17.28 μg/L and 14.11 μg/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-cyhalothrin, 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.
