Abstract :
The relationships between monthly average concentration of atmospheric pollutants, meteorological factors and sulfation rate of 2009 were investigated. It was found that the sulfation rate not only depends on the concentration of SO2, but also significantly associated with PM10, since the surface of PM10 plays an important role in the oxidation of SO2. Pressure and relative humidity play a positive role in improving the sulfation rate. H2O (g) in the air has the ability to condense the pollutants, and the sulfate rate is reduced by the by the precipitation scoured pollutants. Therefore, the sulfate rate is determined by H2O in air rather than the precipitation. The temperature and the wind speed affect the diffusion and dilution of pollutants, thereby determining the sulfation rate.
