摘要
多环芳烃为自然环境中主要有机污染源。为有效控制多环芳烃污染,以广州李坑垃圾填埋场及其周边为研究区域,利用浓度对比分析法和端元混合分析(EMMA)法对研究区地下水中多环芳烃的来源分别进行了定性和定量分析,在端元混合分析中给出了二维主成分空间和三维主成分空间中的端元个数和端元位置,样品1、13、17为地下水中多环芳烃来源的3个端元,进而解析了端元的水文地球化学特征。结果表明,研究区地下水中的多环芳烃主要来自垃圾渗滤液、大气降水以及城市生活污水和工业废水排放。
This paper is concerned specifically with a more effective control of Polycyclic aromatic hydrocarbons （PAHs） , the main organic pollution sources in the natural environment in an effort to obtain a better environment protection. The study targeted at Likeng landfill and its surrounding areas in Guangzhou performs a qualitative and quantitative analysis of the sources of PAHs in groundwater using the methods of comparative analysis of concentration and end member mixing analysis（EMMA）. The analysis of the numbers and location of end members in the two dimensional principal component space and three dimensional principal component space; a subsequent identification of the three sources of PAHs in the groundwater： sample 1, sample 13, and sample 17 ; and an ultimate analysis of geochemical characteristics of end members. The results demonstrate that PAHs in groundwater are mainly attributed to landfill leachate, atmospheric precipitation and municipal wastewater ＆ industrial wastewater.
