高效氯氰菊酯杀虫剂对鲫鱼血清谷丙转氨酶(GPT)和谷草转氨酶(GOT)活力的影响

摘要

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.%本文研究了高效氯氰菊酯对鲫鱼的急性毒性及对血清中谷丙转氨酶 (GPT) 和谷草转氨酶 (GOT)活力的影响.结果表明,高效氯氰菊酯对鲫鱼的96hLC50为11.4 μg L-1.经0.114 μg L-1、0.57 μg L-1、1.14 μg L-1浓度处理后,随着农药浓度的增高和暴露时间的延长,这两种转氨酶的活力升高,表明此农药对鲫鱼机体的损伤也增强.因此,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.
