Abstract：On the side of representative Jihua road (main road ,Tongji road (secondary main road ,Huayuanxi road (branch in Foshan city, PM2.5 samples were collected. And 12 kinds of metal elements and 9 kinds of water-soluble ions in PM2.5 have been analyzied. Results showed that the daily average concentration of PM2.5 in traffic environment of Foshan city were in order: Jihua road (1 3.3 μg/m3 , Tongji road (141.2 μg/m3 , Huayuanxi road (126.0 μg/m3 , had a significant positive correlation with traffic and were higher than the daily average concentration of PM2.5 in urban 64.5 μg/m3. The contents of Fe、Al、Ca、Mg were higher, followed by Zn and Pb in three sampling points. These metals concentrations in each traffic environment were tested highest in Jihua road, followed by Tongji road and Huayuanxi road.The analysis of enrichment factor showed that the pollution of Cd, Zn, Pb, As were the most serious from man-made source. During sampling, SO42-, NO3- and NH4+ were the main water-soluble ions of road environment.
