AbstractAccelerator Mass Spectrometry (AMS) is a new physical technique and it was successfully established in China in 1992. This paper describes the application of AMS in source identification for atmospheric aerosols which was part of the national project of AMS application in environmental research. For comparison, sources were studied using multivariate analysis models such as correspondence factor analysis, principal factor analysis and pattern recognition analysis. The results of the samples collected in suburb of Beijing, analysed by factor analysis, showed that the predominant TSP source was soil which contributed more than 50% to atmospheric particles. However, the AMS results demonstrated that carbonaceous aerosols have quite different emission sources. For carbonaceous aerosols of Beijing, Hunan and Shandong, the contribution to ambient particles from fossil fuel was nearly 2/3, and as human activities (coal-burning, etc.) increases, the fossil part contributes more. Therefore, it is significant to combine the method of factor analysis and AMS in the study of atmospheric aerosols.
