We investigated occurrence of selected compounds (4-t-octylphenol: 4-t-OP; 4-nonylphenols: 4-NP; bisphenol-A: BPA; estrone: E1; 17β-estradiol: E2; triclosan: TCS) and estrogenicity in surface water and sediment of the Yellow River in China by using combined chemical analysis and in vitro yeast screen bioassay. Estrogenic compounds 4-t-OP, 4-NP, BPA, E1, E2 and TCS were measured in the water samples, with their average concentrations of 4.7, 577.9, 46.7, 1.3, ND and 6.8 ng/L, respectively. In sediment, the average concentrations of 4-t-OP, 4-NP, BPA and TCS were 35.7, 0.5, 1.7 and 0.7 ng/g while E1 and E2 were not detected in the sediments of all selected sites. In general, the estrogenic compounds in surface water and sediment of the Yellow River were at relatively low levels, thus having medium to minimal estrogenic risks in most sites except for the site of east Lanzhou with high estrogenic risks.
我们采用化学分析结合体外酵母筛选生物测定法，研究了中国黄河地表水和沉积物中选定化合物（4-叔辛基苯酚：4-t-OP；4-壬基酚：4-NP；双酚-A：BPA；雌酮：E1；17β-雌二醇：E2；三氯生：TCS）的存在及其雌激素活性。水中样品中检测到了 4-t-OP、4-NP、BPA、E1、E2 和 TCS 等雌激素化合物，其平均浓度分别为 4.7、577.9、46.7、1.3、未检出和 6.8ng/L。在沉积物中，4-t-OP、4-NP、BPA 和 TCS 的平均浓度分别为 35.7、0.5、1.7 和 0.7ng/g，而在所有选定地点的沉积物中均未检测到 E1 和 E2。总体而言，黄河地表水和沉积物中的雌激素化合物浓度处于较低水平，除兰州东部高雌激素风险点外，大部分地区雌激素风险处于中低水平。
