Abstract

Cyfluthrin, a synthetic pyrethroid pesticide contaminating aquatic ecosystems as a potential toxic pollutant, was investigated in the present study for acute toxicity. Tilapia fry (Oreochromis niloticus L. 1758) was selected for the bioassay experiments. The 48 and 72h LC(50) was determined for the tilapia fry. The experiments were repeated three times. The static test method of acute toxicity test was used. In addition, behavioral changes at each cyfluthrin concentration were determined for the individuals. Data obtained from the cyfluthrin acute toxicity tests were evaluated using the Probit Analysis Statistical Method. The 48 and 72h LC(50) value for tilapia fry were estimated as 25.82μg/L (95% confidence limits: 20.92-43.26) and 21.07μg/L (95% confidence limits: 16.21-30.39), respectively.

摘要

本研究调查了作为潜在有毒污染物的水生生态系统中拟除虫菊酯农药氯氟氰菊酯的急性毒性。选择罗非鱼鱼苗（Oreochromis niloticus L. 1758）进行生物测定实验。确定了罗非鱼鱼苗的 48h 和 72hLC(50)。实验重复了三次。采用急性毒性试验的静态试验方法。此外，还确定了每个氯氟氰菊酯浓度下个体的行为变化。使用概率分析统计方法评估氯氟氰菊酯急性毒性试验获得的数据。罗非鱼鱼苗的 48h 和 72hLC(50)值分别估计为 25.82μg/L（95%置信区间：20.92-43.26）和 21.07μg/L（95%置信区间：16.21-30.39）。
