摘　　要：通过在西安市三环内6个功能区布设62个采样点,采样分析其表层土壤中邻苯二甲酸酯(PAEs)质量比及其构成特征。结果表明,西安市表层土壤中DMP、DEP、BBP、DnBP、DEHP和DnOP平均值分别为0.188 mg/kg、0.187 mg/kg、0.091 mg/kg、4.174 mg/kg、6.122 mg/kg和0.188 mg/kg,6种PAEs总质量比(∑6PAEs)范围为1.54 mg/kg^153.17 mg/kg,平均值为10.95 mg/kg。6个功能区∑6PAEs从高到低为交通区>工业区>混合区>公园>文教区>住宅区。与其他城市表层土壤中PAEs值比较发现,DMP处于高水平,DEP、DnBP、DEHP和∑6 PAEs处于较高水平,BBP和DnOP处于中等水平。The content and composition of phthalic acid esters(PAEs)in the topsoil were analyzed by setting 62 sampling sites in 6 functional areas inside Xi'an third ring road.The results showed that the average value of DMP,DEP,BBP,DnBP,DEHP and DnOP were 0.188 mg/kg,0.187 mg/kg,0.091 mg/kg,4.174 mg/kg,6.122 mg/kg and 0.188 mg/kg,respectively.The total mass ratio of the six PAEs(∑6 PAEs)ranged from 1.54 mg/kg to 153.17 mg/kg,with an average of 10.95 mg/kg.The content of∑6 PAEs in the 6 functional areas from high to low in order was:traffic area,industrial park,mixed region,park,cultural area,residential area.Compared with other cities,the content of DMP in the topsoil of Xi'an was at a high level,DEP,DnBP,DEHP and∑6 PAEs were relatively higher,BBP and DnOP belonged to moderate level.
