The importance of global environmental problem such as global warming and acid rain as well as local air pollution problem has been recognized worldwide, especially over the last decade. Atmospheric aerosols, especially smaller particles less than 2.5μm (PM2.5) have a key role in those environmental problems. Information on the characteristics of aerosols is essential to understanding their behavior in the atmosphere and the resulting effect on the environment. In this paper, the present state and future assignments of air pollution by aerosols are reviewed and the meaning of innovation of PM2.5 is discussed.
