%X In September 2004, atmospheric particle samples were collected by cascade at meteorological tower at the height of 8 m in Beijing city. The particle samples were analyzed using PIXE method, which resulted in 20 elemental concentrations and elemental distribution. From the observation, the element size distribution, enrichment factors and sources apportionment of particles are analyzed. The fine-mode distribution and high enrichment factors of fine aerosols of K indicated its main source of biomass burning. Factor analysis on the chemical composition of particles shows that sources of soil matters, biomass burning, coal combustion, industry dust and vehicle emission contributed to aerosols in autumn in Beijing.
