To investigate the pollution levels, occurrence and distribution of estrogens, six estrogens in the surface sediments of Wenyuhe River were analyzed quantitatively by GC/MS following ultrasonicated extraction including diethylstilbestrol (DES), estrone (E1), beta-estradiol(E2), 17alpha-ethynylestradiol(EE2), estriol(E3), and beta-estradiol 17-valerate (EV). Six estrogen concentrations ranged from 0.39-36.6 ng/g and the mean concentration was 10.2 ng/g. E1 and E2 were detected in all samples while other four estrogens were only detected in a few samples, and the concentrations of El was higher than those of E2 in all samples. There were significant correlation relationships between the concentrations of six estrogens and the concentrations of total organic carbon (TOC), total phosphorus (TP) and total nitrogen (TN) in sediments. Considering also the characteristics of the sampling locations and pollution sources, six estrogens should come from wastewater discharges along the river and the contaminated tributaries. The contents of estrogens in this area are medium or slightly higher level compared with other areas abroad.
为了调查雌激素的污染水平、存在情况和分布，采用超声萃取后用气相色谱/质谱联用仪（GC/MS）对温榆河表层沉积物中的六种雌激素进行了定量分析，这六种雌激素包括己烯雌酚（DES）、雌酮（E1）、β-雌二醇（E2）、17α-乙炔基雌二醇（EE2）、雌三醇（E3）和戊酸雌二醇（EV）。六种雌激素的浓度范围为0.39 - 36.6 ng/g，平均浓度为10.2 ng/g。所有样品中均检测到E1和E2，而其他四种雌激素仅在少数样品中检测到，且所有样品中E1的浓度均高于E2。六种雌激素的浓度与沉积物中总有机碳（TOC）、总磷（TP）和总氮（TN）的浓度之间存在显著的相关关系。综合考虑采样地点的特征和污染源，六种雌激素应来自沿河的废水排放以及受污染的支流。与国外其他地区相比，该地区雌激素的含量处于中等或略高的水平。
