摘要/Abstract

摘要： 持久性有机污染物引起的水质安全性问题日益受到广泛关注．为探究太湖饮用水源地多环芳烃的污染情况，对太湖饮用水源地表层沉积物进行了采样，对多环芳烃进行了定量检测，分析了研究区沉积物中多环芳烃浓度分布，同时采用2种方法(特征化合物法和主成分分析法)进行溯源分析．结果表明：太湖饮用水源地表层沉积物检测出11种PAHS，总量介于nd～280 ng·g－1之间，平均值为114 ng·g－1.和国内外其他湖泊、河口及海湾地区相比，太湖饮用水源地PAHs污染处于低水平．太湖饮用水源地表层沉积物PAHs组成以4环及5～6环PAHs为主(分别为43.86%和50.88%)，2～3环PAHs相对较低(5.26%)．太湖饮用水源地表层沉积物PAHs主要来源为化石燃料(包括汽油、柴油、煤、木柴等)的燃烧，但也与石油污染有关．本文成果可为太湖流域水污染防治和水资源管理提供科学参考．

Abstract: Water security problems caused by persistent organic pollutants(POPs)increasingly attracted widespread attention.To better understand the pollution characteristics of polycyclic aromatic hydrocarbons(PAHs)in lake surface sediment of Taihu Lake，surface sediments samples in drinking water sources in Taihu Lake Basin were chosen and the concentration distributions of the samples were analyzed.Two methods(characteristic compound and principal component analysis)were used to identify the sources of the PAHs.The results showed that：The concentrations of 11 PAHs compounds detected ranged from 0 to 280 ng·g－1 and the average value was 114 ng·g－1.Compared with other lakes，PAHs pollution of drinking water sources in Taihu Lake Basin was at a low level.The spectrum of PAHs showed that 4ring and 5～6ring PAHs were predominant，which accounted for 43.86%，50.88% of the total，respectively.2～3ring PAHs accounted for only 5.26%.PAHs in surface sediments of drinking water sources in Taihu Lake Basin were mainly produced by fossil fuels(including gasoline，diesel fuel，coal，wood，etc.)of combustion，but maybe also by oil pollution.The results of the study can provide scientific reference for water pollution prevention and water resources management of Taihu Lake Basin.
