Abstract:
Fine particles in atmospheric aerosols(PM10, PM2.5) are a key of study on atmospheric aerosols in recent years. There are multiple of chemical elements and compounds in fine particles. The chemical elements would change with spatial and temporal variability in fine particles. It is found that the fine particles come mainly from vehicle exhausts, fossil, oil-bearing and biomass fuel combustion made by mankind and secondary polluted products in atmosphere.
