摘　　要：[目的 ]进一步了解 G市水源水及自来水有机污染物的种类及污染状况。 [方法 ]采集 G市两个水厂水源水及自来水 ,以 GDX树脂富集 ,气相色谱 -质谱 (GC/ MS)进行定性分析 ,气相色谱 -电子捕获检测器 (GC- ECD)进行定量分析。 [结果 ]水源水中共鉴定出 87种有机化合物 ,自来水中鉴定出 34种化合物 ,其中环状化合物 (含芳环 )占半数以上。 [结论 ]工业排污对水源水质影响大 ,水源位于下游工业区的有机污染较上游严重 ,经过处理的自来水仍含有多种毒害有机污染物。Objective]To explore the kinds of organic pollutants and the status of water pollution in source water and tap water in G city.[Methods]The qualitative analysis and the quantitative analysis of the organic pollutants in water samples of source water and tap water collected from two water plants and enriched by GDX resin were carried out by GC MS and GC ECD respectively.[Results]87 and 34 kinds of organic compounds were found and identified in source water and tap water respectively,more than one half of which were cyclic compounds including aroma tic hydrocarbons.The levels of organic compounds obtained from quantitative analysis ranged from 0 58 ng/L to 0 2 μg/L.[Conclusion]The sanitary quality of source water had been heavily impacted by drainage of industrial sewage.The water source located in industrial area of the lower reaches of the river was highly polluted by organic compounds compared with that in upper reaches.Many kinds of hazardous organic pollutants still existed in the treated tap water.
