Analysis of organic and inorganic components of inhalable particles in the atmosphere.

Samples of total suspended particulate matter and inhalable particles were collected from the atmosphere in Beijing, Shanghai, Wuhan, Taiyuan, and Zibo. The size distribution of particles, the variations in their concentrations during different seasons, and the concentrations of 10 kinds of inorganic elements and polycyclic aromatic hydrocarbons were also obtained. This information provided a scientific basis for studying the effects of particle pollution on human health, for formulating health standards, and for taking preventive measures.
