| 摘 要： | 用高分辨率,高灵敏度的质子微探针对上海市人民公园大气气溶胶进行单颗粒源解析.结果发现,上海市大气主要污染源为土壤扬尘、建筑扬尘、汽车尾气和钢铁工业尘,它们对大气环境贡献率之和为80%以上.此外还发现约有13%的颗粒物无法识别,通过对这些颗粒物进行聚类分析,初步确定它们分属于2种不同污染源的亚类和一种新的未知的污染源.

| Abstract: | A proton microprobe with high resolution and high sensitivity was applied to analyze atmospheric aerosol in the people's park in Shanghai urban for single particle source apportionment. The results showed that the sum of the average contribution rates from the sources of soil dust, building construction dust, vehicle exhaust and metallurgical industry, which are the main pollution sources of atmospheric aerosol in Shanghai urban and surpasses 80%. Besides, about 13% of the particles could not be identified. On the basis of cluster analysis of these particles, they are preliminary known belonging to two different individual sub pollution sources and a new unidentified pollution source. |
