摘　　要：采用SOS/umu方法与双杂交酵母体系检测了珠三角某地区1家污水处理厂进出水样品、7个工业企业废水和排水样品以及6个受纳水体样品共15个样品的遗传毒性与雌激素效应。结果表明,该区域污水厂进出水、工业企业废水和排水以及受纳水体均表现出显著遗传毒性效应,且受纳水体的雌激素效应高于污水厂出水及工业企业排水。对于污水厂进出水及工业企业排水,在低浓度(1.57~12.5 mL/孔)暴露条件下,遗传毒性R值在3.03~4.18之间;受纳水体未表现出显著细胞毒性,低浓度(1.57~12.5 mL/孔)暴露条件下,其遗传毒性R值在1.67~5.13之间;污水厂进出水、工业企业废水和排水样品中只有染织厂废水和排水以及电路厂排水具有弱雌激素效应,诱导活性在0.026~0.041之间;6个受纳水体样品中则有4个样品具有显著雌激素效应,诱导活性在0.048~0.105之间。受纳水体仍存在大量具有遗传毒性与雌激素效应污染物,其遗传毒性水平基本与工业废水持平,雌激素效应则高于工业废水。The genotoxicity and estrogenic effects of fifteen water samples from the influent and effluent of a sewage treatment plant,the raw wastewater and drainage of seven industrial enterprises and six receiving water in a region of the Pearl River Delta were detected by using SOS/umu test and a recombinant yeast system.In this region,the influent and effluent of the sewage treatment plant,the industrial wastewater and drainage and the receiving water all showed significant genotoxic effects,and the estrogenic effect of the receiving water was higher than that of the effluent from the sewage treatment plant and the drainage from the industrial enterprises.The genotoxic R values ranged from 3.03 to 4.18 at low exposure concentrations(1.57 mL/well to 12.5 mL/well)for the influent and effluent of the sewage treatment plant as well as the industrial drainage.No significant cytotoxicity was showed in the receiving waters,and the genotoxic R value was between 1.67 and 5.13 at low exposure concentrations(1.57 mL/well to 12.5 mL/well).Among water samples from the influent and effluent of the sewage treatment plant,industrial wastewater and drainage,only the raw wastewater and drainage from the printing and dyeing factory and the drainage from electric circuit factory had weak estrogenic effects,and the induced activity ranged from 0.026 to 0.041.Four of the six water samples from the receiving waters showed significant estrogenic effects,and the induced activity ranged from 0.048 to 0.105.There were still a large number of pollutants with genotoxicity and estrogenic effects in the receiving waters.The genotoxic level was basically equal to that of the industrial wastewater,while the estrogenic effect was higher than that of the industrial wastewater.
