摘　　要：以西安城市表层土壤中PAEs为研究对象,利用高效液相色谱仪(HPLC)检测了城市表层土壤中美国环境保护部(U.S. EPA)优控的6种PAEs(DMP,DEP,BBP,DnBP,DEHP和DnOP)含量。重点分析了城市表层土壤中PAEs的来源。相关分析、主成分分析和聚类分析表明,西安市表层土壤中DnBP和DEHP主要与增塑剂的使用有关;DMP和DEP与居民日常个人护肤品、化妆品以及洗漱用品的使用有关;此外,DMP和DEP以及BBP与DnOP还与工业生产排放、室内外装修材料和建筑材料等的释放有关。In this paper,the semi-arid city of Xi'an city,Northwest China was elected as the research area and the PAEs in topsoil was considered as the research targets.The concentrations of six priority PAEs(DMP,DEP,BBP,DnBP,DEHP,DnOP)of United States Environmental Agency(U.S.EPA)were analyzed by high performance liquid chromatography(HPLC).Based on the analyses of physiochemical characteristics and PAEs concentrations in topsoil,the source of PAEs in topsoil were further studied.Correlation analysis,principal component analysis and cluster analysis showed that DnBP and DEHP in topsoil of Xi'an were mainly related to the usage of plasticizer.DMP and DEP were associated with personal care products,cosmetics and toiletries.In addition,DMP,DEP,BBP and DnOP were contributed to emissions of industrial productions PAEs-containing as well as indoor/outdoor decoration materials and building materials.
