摘　　要：目的调查研究"引江济太"工程对太湖水源水雌激素活性的影响。方法分别于2013年12月、2014年1月和3月采集江苏省W市"引江济太"工程8个相关地点水样,应用固相萃取技术结合重组酵母雌激素筛检试验(recombinant yeast estrogen screen,YES)和液相色谱质谱联用(LC-MS/MS)分析方法,对水样中的有机物雌激素活性强度、酚类雌激素物质含量水平及变化规律进行分析,探讨调水量和相关水源水的雌激素活性及其中酚类雌激素物质的关系。结果各水样均表现出明显的雌激素活性,并且以望虞河入太湖口处的水样雌激素活性效应最强,该水样的酚类环境雌激素物质含量也最高。太湖内各水样雌激素活性强度与靠近望虞河口的距离呈正相关。结论以太湖水为源水的XD水源水和NQ水源水均不同程度受到了长江经望虞河引入太湖水的影响,并且其雌激素活性强度随着引水量增加而升高,呈现出正相关。Objective To investigate the impact of the ＂Water Diversion from the Yangtze River to Taihu Lake＂project on the estrogenicity of water from Taihu Lake,which is an important source of water in Jiangsu province. Methods Water samples were collected from 8 points of the ＂Water Diversion from the Yangtze River to Taihu Lake＂project from December 2013 to March 2014. Organic constituents in water samples were extracted by solid phase extraction（ SPE）,the estrogenicity was evaluated by recombinant yeast estrogen screen（ YES）,and estrogenic phenols were determined by liquid chromatography coupled with tandem mass spectrometry（ LC-MS /MS）. Results All water samples could induce significant estrogenic activity; the estrogenic activity of water samples collected from the mouth of Wangyu River was the strongest,and the level of estrogenic phenols was the highest. The nearer of the distance to the mouth of Wangyu River the stronger of the estrogenic activity presented.Conclusions The source water of XD and NQ derived from Taihu Lake were affected by the water diverted from Wangyu River,the intensity of estrogenic activity in Taihu Lake water was positively correlated with the volume of water introduced from Wangyu River.
