摘　　要：研究了对硝基酚对中国淡水水生生物毒性效应,包括15个属18个物种的33个急性毒性数据和大型溞(Daphnia magna)与虹鳟鱼(Oncorhynchus mykiss)的无观察效应浓度(NOEC)慢性数据。应用物种敏感度分布曲线法推导了我国的淡水水生生物对硝基酚基准最大浓度为163.47μg/L,基准连续浓度为36.01μg/L。与我国水体中对硝基酚的浓度相比,对硝基酚尚未对水生系统产生影响,其潜在风险不大。研究结果为我国的对硝基酚水质标准研究提供了参考依据。The toxicity of p-nitrophenol to aquatic organisms in China, including 33 acute toxicity data of 18 species of 15 genera and chronic NOEC of Daphnia magna and Oncorhynchus mykiss, was investigated. And then species sensitivity distribution method was applied to derive the freshwater quality criteria of p-nitrophenol in China. The results showd that the criteria maximum concentration and criteria continuous concentration for p-nitrophenol were 163.47μg/L and 36.01μg/L, respectively. Compared to the exposure concentrations in surface water of China, the effects and potential risks of p-nitrophenol on aquatic ecosystem are limited. The study results can provide some evidence for deriving water standard of p-notrophenol in China.
