| 3 | On the study of aerosol composition at the Great Wall Station, South Pole显示文摘The South pole aera offers one of the best locations on the Earth for studying the composition of the background aerosol. For this purpose, aerosol samples were collected in particle size fractions by 8 stages cascade impactors. Aerosol sampling was begun in Jan. and finished in Dec. 1986 at the St. Great Wall, South Pole. The samples were analysed by Proton Induced X-ray Emission (PIXE) method. In order to learn the enrichment factors of various elements all the results were separated into two groups: coarse (> 10μm) and fine (< 10μm) particles. The correlation coefficients of elements of both coarse and fine particles were discussed. The aerosol levels measured at St. Great Wall were compared to those recently measured at some other locations. It can be concluded the South Pole is a good background area on the Earth. | Ma Ciguang, Li Min, Zhang Yongping, Li Hongzhen, Zhu Peiran and Liu Jiarui1 Research Center for Eco-environmental Sciences, Academis Sinica, Beijing,China2 Polar Meteorological Research Lab, Academis of Meteorobeical Sci,S.M.A, Beijing, China.3 Institute of Physics,Academia Sinica Beijing,China。 | 1989 | Journal of Environmental Sciences1989，1，1： | 0 |
