摘　　要：采用GC/MS对温榆河上游及干流的主要排污口、重点闸坝、主要入河口等河段表层沉积物中的壬基酚(NPs)和双酚A(BPA)进行了分析测定.结果表明,样品中普遍检出NPs和BPA,浓度范围分别为125—8157.9ng·g-1和0.6—59.6ng·g-1.其浓度水平与水中总有机碳(TOC),总磷(TP)和总氮(TN)具有显著的正相关,结合采样点周边入河污染源的分布情况,判断其主要来自沿岸入河排污口和污染支流.In present work, concentrations of nonylphenols（NPs）and bisphenol-A（BPA）in the sediments of Wenyuhe river were analyzed quantitatively by GC/MS. The results showed that NPs and BPA could be detected in all samples and their concentrations ranged from 125—8157.9 ng·g^-1 and 0.6—59.6 ng·g^-1, respectively. There were significant correlation relationships between NPs and BPA concentrations and 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, it indicated both NPs and BPA should come from effluents points of wastewater discharges along the river and the contaminated tributaries.
