The investigation of particulate matters (PM10-2.5 and PM2.5) was carried out through this research during period sampling data from 2008 to 2011 (including winter and summer seasons). The concentration of heavy metals (As, Cd, Cr, Cu, Mn, Ni, Pb) were analyzed by graphite furnace atomic absorption spectrometry. Moreover, the principle component analysis and hierarchical cluster analysis were used to investigate the pollutant source and profiling the spatial of PM10-2.5 and PM2.5. The results show that the concentration of As was collected with an air flow in diffusion (wind speed > 2 m/s) and relative humidity between 50% to 70% in PM10-2.5. In addition, the concentration of As was collected when air flow in diffusion and relative humidity between 50% to 80% in PM2.5. It is interesting to noted that the probability of the high concentration of As being 13% over the standard of EU. The concentration of As in PM2.5 trends to be increased in recent year.
