摘　　要： 分别在典型电子垃圾拆解区（E）和其参考区（S）采集了大气总悬浮颗粒物（TSP）样品,利用等离子体电感耦合质谱（ICP-MS）检测了13种元素。结果表明,E地区大气TSP中各元素含量均高于对照区,特别是污染元素Zn、Cu、Cd、Sn和Pb。E地区和S地区TSP中元素质量浓度的季节变化趋势相似,TSP中地壳元素质量浓度夏季高于冬季,而污染元素冬季高于夏季。E地区和S地区TSP中Cu、Zn、Sn和Pb的富集因子（EF）〉100,E地区EF值高于对照区,说明这些元素主要来源于电子垃圾处理过程;而Mg、K、Ca、Ti、V、Mn、Fe、Co和Cd的EF值为1~10,说明元素主要为自然来源。 TSP samples were collected in typical E-waste site（E） and reference site（S）.13 elements were detected using ICP-MS in an analyzing sample processe.Result indicated that concentrations of all detected inorganic elements in E-waste site were higher than that in reference site,especially for Zn,Cu,Cd,Sn and Pb.Seasonal variation of elements in site E and site S was similar.The concentrations of the earth elements in summer were higher than that in winter;however,the heavy metal element concentrations in winter were higher than that in summer.Enrichment factors（EF） of Cu,Zn,Sn and Pb in site E and site S were obvious higher than 100 and EF values in site E were higher than those in site S,which suggested that they were typical pollutant elements and these elements were mainly from E-waste dismantling process.EF of Mg,K,Ca,Ti,V,Mn,Fe,Co and Cd were ranging from 1 to 10,which indicated a natural origin.
