摘要
本试验开展了溴氰菊酯对菲律宾蛤仔的单因子急性毒性研究。溴氰菊酯对菲律宾蛤仔24h,48h、72h和96h的半致死浓度(LC50)值分别为0.95mg/L,0.125mg/L、0.075mg/L和0.0583mg/L,96h的安全质量浓度为0.649μg/L。在短时间(24h-96h)内,菲律宾蛤仔体中溴氰菊酯积累量的高低主要受控于其曝露时间的长短,并非取决于水体中溴氰菊酯浓度的高低。
This experiment carried out the single factor acute toxicity study of deltamethrin to Philippines ruditapes, the lethal concentrationS0（LC50） of 24h, 48h,72h and 96h were 0. 95 mg/L, 0. 125 mg/L, 0. 075 mg/L and 0. 0583 rag/L, The safe concentrations of 96h was 0. 649 μg/L. In a short time （24h-96h）, the deltamethrin accumulations in Philippines ruditapes body are mainly controlled by the exposure time, not depend on the level of deltamethrin concentration in water.
