| 中文摘要: |
| 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- M S) 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 |

| TSP samples were collected in typicalE-waste site(E) and referencesite(S). 13 elements were detected usingICP-M Sin an analyzingsampleprocesse. R esultindicatedthatconcentrationsofalldetected inorganicelem entsin E-wastesite were higherthan thatin referencesite, especially forZn, Cu, Cd, Sn and Pb. Seasonalvariation ofelementsinsiteE and siteS wassim ilar. The concentrationsoftheearth elementsin summerwere higherthanthatin winter; however, the heavym etalelementconcentrationsin winterwere higher thanthatinsummer. Enrichmentfactors(EF) ofCu, Zn, Sn and Pb in site E andsiteS wereobvioushigher than 100 and EF valuesin siteE werehigherthanthosein siteS, which suggestedthatthey weretypicalpollutantelementsandtheseelementsweremainlyfrom E-waste dismantling process. EF ofM g, K, Ca, T,i V, M n, Fe, Co and Cd wererangingfrom 1to10, which indicated a naturalorigin. |
