摘要
在复旦大学加速器实验室利用PIXE技术分析了几千例采自上海、北京、天津、太原、拉萨、珠峰和南极长城站的气溶胶样品,对以上城市和地区气溶胶中Al、Si、S、Cl、K. Ca、Ti、Fe、Cu、Zn、Pb和Br等12种主要成分作了比较并讨论了它们与气溶胶粒径、采样时间的关系,以北京的气溶胶样品分析数据为例探讨了不同类型的污染源对气溶胶总质量的贡献.
Thousands of atmospheric aerosol samples have been analyzed by PIXE at Accelerator Lab. of Fudan University. These samples were sampled in Shanghai, Beijing, Tianjin, Taiyuan, Lhasa, on the Mt. Jolmo Lunma and at the Great Wall Station of China in the Antarctica, etc. In this paper, the concentrations of 12 main elements i.e. Al, Si, S, Cl, K, Ca, Ti, Fe, Cu, Zn, Pb and Br, in the atmospheric aerosol samples are listed and the variations of some elemental concentrations with aerosol particle size and with time are shown. Some kinds of pollution sources in Beijing are discussed.
