摘　　要：采用多环芳烃检测、LC50检测和发光细菌检测3种方法对重柴油污染的生态毒性进行初步研究。研究结果表明:重柴油中检测出16种有毒有害多环芳烃化合物;对海洋生物日本大螯蜚半致死质量浓度(LC50)为0.105 mg/L;发光细菌检测生态毒性相当氯化汞质量浓度为0.088 mg/L,表明发光细菌法检测海水油污染生态毒性是一种可行的方法。The overflow of oil had a dramatic impact on the marine ecological environment. But there are no standard test methods of the ecotoxicity of oil pollution in seawater. A preliminary study mainly focused on the ecotoxicity of heavy diesel oil in seawater by detection of PAHs, LC50 detection and luminescent bacteria test. The results showed that heavy diesel oil contained 16 kinds of PAHs. At the same time, the LC50of GrandidiereUajaponica was 0. 105 mg/L. The correspondent concentration of HgCl was about 0. 088 mg/L. It also demonstrates that the luminescent bacteria test is a feasible method to detect ecotoxicity of oil pollutant in seawater.
