In this experiment, the effects of beta-cypermethrin on acute toxicity and serum GPT and GOT of crucian were studied. It was indicated that the 96hLC50 of beta-cypermethrin was 11.4 μg L-1. The crucian serum was treated at the levels, 0 μg L-1, 0.114 μg L-1, 0.57 μg L-1, 1.14 μg L-1 for 0 d 5 d 10 d 15 d and 20 d, respectively. The results showed that beta-cypermethrin could make great damage to crucian biochemical characteristics, and suggested that the effects of toxicant on serum GPT and GOT could be used as an index of toxicological assessment.
试验结果表明,高效氯氰菊酯对鲫鱼的96 h LC50为11.4μg/L。经0.114μg/L、0.57μg/L、1.14μg/L质量浓度处理后,随着农药质量浓度的增高和暴露时间的延长,谷丙转氨酶(GPT)和谷草转氨酶(GOT)的活力升高,表明此农药对鲫鱼机体的损伤也增强。GPT和GOT活性可以作为杀虫剂对环境安全性的一种评价标准。
