实验研究了敌杀死对几种常见海水桡足类的毒性。查明敌杀死对中华哲水蚤24小时半致死浓度为0.036×10-6,全致死浓度为0.07l×10-6;48小时半致死浓度为0.03l×10-6,全致死浓度为0.060×10-6;72小时半致死浓度为0.028×10-6,全致死浓度为0.044×10-6;96小时半致死浓度为0.026×10-6,全致死浓度为0.039×10-6。敌杀死对几种小型桡足类的96小时最低全致死浓度均不超过0.0055×10-6。以0.08×10-6作为该药的使用浓度时.解毒时间为7天。
The toxicity of killing to several common sea water copepods was experimentally studied. The results showed that the median lethal concentration was 0.036 × 10-6, the lethal concentration was 0.07l × 10-6, the median lethal concentration was 0.03l × 10-6 at 48h and the lethal concentration was 0.060 × 10-6; the lethal concentration at 72 hours is 0.028 × 10-6, the lethal concentration is 0.044 × 10-6; the lethal concentration at 96 hours is 0.026 × 10-6 and the lethal concentration is 0.039 × 10-6. Eradication of several small copepods 96 hours minimum lethal concentration of not more than 0.0055 × 10-6. When 0.08 × 10-6 was used as the drug, the detoxification time was 7 days.
