Abstract: Atmospheric particle samples were collected during December at Shanxi in Taiyuan in the winter of 2004 and were analyzed by PIXE which results in 20 element concentrations and elemental distribution. From the observation data of 1983,the element concentrations ,elemental distribution and possible sources of atmospheric distributions of the elements such as Ca , Ti , S , Cu and Pb do not change much, while the size distributions of As、Se、Br have changed to be three peak values modle due to road dust, Al ,V, K and Mn have changed to be fine mode due to anthropogenic sources. The enrichment factors of elements such as Cu、Zn、Br、Pb are very high due to heavy pollutions. Factor analysis further indicated that there are three main sources of Shanxi atmospheric particle concentrations:the soil and dust, metallurgical industry dust, coal combustion dust..

Key words: aerosol, elemental concentration, factor analysis
