Abstract：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 .
