Thousands of atmospheric aerosol samples have been analyzed by PIXE at accelerator lab of Fudan university since 1980. These samples were sampled in Beijing, Shanghai, Tianjin, Taiyuan, Shanyang, Lhasa, on the Mt. Jolmo Lungma and at the Great Wall Station of China in the Antarctica, etc., by samplers of Model DK-60 and Wuan-75, cascade impactor and streaker. In this paper, the 12 main elemental concentrations, e.g., AI, Si, S, Cl, K, Ca, Ti, Fe, Cu, Zn, Pb and Br of the atmospheric aerosol in the cities and area mentioned above are listed and the variations of some elemental concentrations with aerosol particle size and with time are shown. The results are discussed.
