| 中文摘要: |
| 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0188 mg/kg、0187 mg/kg、0091 mg/kg、4174 mg/kg、6122 mg/kg和0188 mg/kg，6种PAEs〖JP3〗总质量比(SymboleC@6PAEs)范围为154 mg/kg ～15317 mg/kg，〖JP〗平均值为1095 mg/kg。6个功能区SymboleC@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SymboleC@6PAEs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 Xian third ring road. The results〖JP3〗 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〖JP〗， 6.122 mg/kg and 0.188 mg/kg， respectively. The total mass ratio of the six PAEs （SymboleC@6PAEs） ranged from 1.54 mg/kg to 153.17 mg/kg， with an average of 10.95 mg/kg. The content of SymboleC@6PAEs 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 Xian was at a high level， DEP， DnBP， DEHP and SymboleC@6PAEs were relatively higher， BBP and DnOP belonged to moderate level. |
