| 摘 要： | 测定了太原市不同粒径大气颗粒物中１６种金属元素含量，分析了太原市大气环境中金属元素的污染状况、富集特征及其主要污染来源。结果表明，太原市大气环境中多数金属元素在颗粒物中的含量冬季明显高于夏季、工业区和市区的金属元素浓度水平远高于郊区。对人体危害较大的金属元素主要富集在≤２．０μｍ的细颗粒上。根据富集因子分析表明Ｐｂ、Ｃｕ、Ｚｎ、Ａｓ、Ｓｅ等主要来自人为污染，Ａｌ、Ｆｅ、Ｃａ等主要来自自然来源。

| Abstract: | Airbone particle samples were collected using a five-stage classification air sampler. The contents of 16 metals in different diameter airbone particles were determined by atomic absorption spectrophotometry. Variations in the contents of metals were observed in different seasons and areas. The results showed that the contents of most metals were higher in winter than in summer. The contents of metals were higher in urban districts than in suburbs. The metals of being harmful to human body mainly concentrated in the < or = 2.0 microns particles. The enrichment factor of metals was calculated. The results showed that Pb, Cu, Zn, As, Se and Sb mainly originated from man-made pollution, while Al, Fe and Ca mainly originated from natural sources. |
