摘要：Earthworm acute toxicity, plant seed germination bio-toxicity tests were conducted to evaluate the contaminated site polluted by a pharmaceutical intermediates accident. In the earthworm acute toxicity test, the mortality rate of earthworms in the control group was 0, while the earthworms mortality rate in the two groups of contaminated soil both reached 100% within 24h and three days respectively. The plant seed germination rates of four species except ryegrass were all less than 20% in the treatment dose (contaminated soil: reference soil, 25%). The test results indicated that the soil samples showed high biological toxicity. Eco-toxicity tests can effectively characterize the ecotoxicity and be used in quick identification of accident hazard and risk assessment in environmental emergency response. In addition, it can provide government departments with the basis for the environmental management and provide technics of detailed site survey and risk assessment for relevant scientific research departments and enterprises as well.
