Abstract: An Anderson dichotomous sampler was operated with Teflon filter membrane to collect fine(dp<2.5 m, PM2.5) and coarse particulate(2.5 mdp10 m,PM2.510). The element content was determined by Xray fluorescence. The volume fractions, mass fractions and enrichment coefficients of artificial pollutionrelated elements and the volume fractions of typical earth crust elements in both fine and coarse particulates were analyzed. The result indicated that the pollution of the particulaterelated elements in PM2.5 and PM2.510 in Guangzhou was pretty serious and it was more serious in PM2.5 than that in PM2.510. The pollutionrelated elements were easier to be enriched in the fine fraction, especially in the contrast site, and that the most seriouspollution elements were S,Cl, Zn and Pb. It showed that the air pollution in Guangzhou possessed the characteristic of coal smoke pollution of SOx, and also possessed the characteristic of vehicle emissions pollution simultaneously.
