摘　　要：于2010年10月～2012年3月期间4次采集江苏WX和SZ地区长江、太湖水源水及相关自来水厂出厂水共43个水样,通过XAD-2树脂吸附、洗脱、浓缩其中的非挥发性有机物(nonvolatile organic compounds,NVOCs);应用重组酵母雌激素筛检试验(recombinant yeast estrogen screen,YES试验)检测和比较水中有机物雌激素活性水平.结果表明所有长江、太湖水源水样均具有雌激素活性,太湖水源水的雌二醇当量(EEQs)为0.04～2.07 ng.L-1,EC25-E2水样量为5.78～207.98 mL,长江水源水的雌二醇当量(EEQs)为0.69～1.15 ng.L-1,EC25-E2水样量为9.06～31.62 mL;SZ地区太湖水源水中具类雌激素内分泌干扰物的污染程度(0.69 ng.L-1)高于WX地区(0.44 ng.L-1);长江、太湖水源水经自来水厂常规净水工艺处理后,58.3%的出厂水样未检出雌激素活性,长江水源自来水厂可降低雌激素活性80.3%～100%,而太湖水源自来水厂可降低55.5%～100%.A total of 43 source water and finished water samples were collected from the Yangtze River and Taihu Lake in WX and SZ areas of Jiangsu Province from October 2010 to March 2012. The XAD-2 resin was applied to absorb the organic compounds in each water sample respectively. After the procedure of elution, concentration and drying, nonvolatile organic compounds （NVOCs） were obtained. The recombinant yeast estrogen screen test was then applied to evaluate the estrogenic activities of NVOCs in each water sample. The results showed that all of the source water collected from the Yangtze River and Taihu Lake possessed estrogenic activities. The EEQ values of source water from Taihu Lake were 0. 04-2.07 ng.L-1 , and the volume of EC25_E2 were 9.06-31.62 mL; the EEQ values of source water from Yangtze River were 0. 69-1. 15 ng＂ L- l , and the volume of EC2s_E2 were 9.06-31.62 mL. The samples from Taihu Lake in SZ area had higher estrogenic activities than the samples collected from WX area. No estrogenic activity was detected in 58.3% of the finished water samples after the treatment in water plants. The water plants which collected source water from the Yangtze River and from Taihu Lake reduced the estrogenic activities by 80.3%- 100% and 55.5% -100% , respectively.
