Abstract: Airborne particulate matter, especially the fine particles PM_2.5, is an important component of ambient air. Airborne particles have serious impacts on human health due to their association with toxic matters. They can also exert important effects on environment and climate through hygroscopic growth, cloud condensation nuclei activity and light absorption and scattering. The long range transport of particulate matter can affect the regional and global geochemical cycle. In this paper, physical and chemical characteristics of airborne particles are discussed and the on-line and off-line analytical techniques are introduced. In addition, application of source apportionment methods has been evaluated and the effects of airborne particles on environment, climate, human health, and global geochemical cycle have been expounded. Finally, the research prospect of airborne particles is presented.
