临安大气污染本底站气溶胶特征分析

In this paper, the physical and chemical characteristics of the aerosols which were observed at Lin'an air pollution bachground station (WMO station) in Zhejing Province, China from early August to late November, 1991 such as the element and ion concentrations, the particle size distributions, the particle morphology, the enrichment degree of the aerosol elements, and the relationship between them have been analyses. The effects of some meteorological elements on the aerosol concentration distribution are discussed, too. In addition, the origion of aerosol is investegated.
