摘　　要：以三种已被确认的环境内分泌干扰物邻苯二甲酸二丁酯(DBP)、壬基酚(NP)和双酚A(BPA)为研究对象,分别采用气质联法(GC-MS)对某市黄河水净水厂原水、沉淀后水、过滤后水、出厂水以及经管网输送至用户后的自来水进行了分析。结果表明,净水厂原水、沉淀后水、过滤后水、出厂水、及用户水中均含有三种内分泌干扰物,其中邻苯二甲酸二丁酯和壬基酚在出厂水中仍分别超过国家标准和推荐的安全控制值。在净水厂内,原水中三种物质的含量都比较高,出厂水中最低,说明水厂传统的处理工艺对这三种有机物有一定的净化效果,其中以处理步骤加氯对三种有机物的处理效果最为显著。而经过管网输送后的用户水样中,壬基酚和双酚A的含量高于出厂水,这可能是在输水过程中受管道沉积污染物的影响所致。Using the method of gas chromatography-mass spectrometry （GC/MS）, the contents of di-n-butyl phthalate（DBP）, nonylphenol （NP） and bisphenol A（BPA）, which have been confirmed as environmental endocrine disruptors（ EEDs）, in the raw water, deposited water, filtered water, tail water of a Yellow River Water Plant, and the transported water by pipeline in user have been determined. The results indicate that the three chemicals present in all the water samples, and the contents of DBP, NP in tail water excess the National Standard and the recommended safety controlling value separately. The contents of DBP, NP and BPA are highest in the raw water and the lowest in the tail water, which indicates that the conventional water cleaning technology can remove DBP, NP and BPA from surface water in some extent. But in the water sample of user, the content of NP and BPA is even higher than that in the tail water of the water plant, which may be resulted from the pollution of water transported pipelines.
