摘　　要：研究了23～25℃下2、5、10、20日和30日龄卤虫对钻井液的96 h毒性耐受力的差异。试验结果表明，随着试验时间的延长，不同质量浓度钻井液对卤虫死亡率的影响差异性逐渐增大，试验96 h时，除钻井液质量浓度为2000 mg／L组与对照组死亡率差异不显著外，4000、6000、8000、10000 mg／L质量浓度组均与对照组差异显著（ P＜0．05）；2、5、10、20日和30日龄卤虫的96 h半致死质量浓度分别为3464、3488、3452、4811、2592 m g／L ，随着试验时间的延长，各日龄卤虫之间的死亡率差异逐渐降低。The 96h biological toxicity of drilling effluent to two ,five ,ten ,twenty and thirty day old brine shrimp A rtemia saline was studied at water temperature from 23 ℃ to 25 ℃ .The results showed that the differences in mortality of the brine shrimp caused by different concentrations of drilling effluent were found to be increased with the test period elapse .There were significant differences in mortality between the second ,third ,fourth and fifth brime shrimp groups and the control group （P〈 0 .05） ,except for between the first group and the control group in 96 h test .The 96 h LC50 was found to be 3464 mg/L in 2 day old A rtemia ,3488 mg/L in 5 day old A rtemia ,3452 mg/L in 10 day old A rtemia ,4811 mg/L in 20 day old A rtemia ,and 2592 mg/L in 30 day old A rtemia ,with the test time elapse ,the differences in mortality being decreased among all age A rtemia .
