• Point source
• Sulfation rate

Air pollutant SO2 of Maanshan mainly comes from point sources in field of iron and steel industry, including ore smelting, coking and industrial boiler. Based on the data, such as energy structure, previous industrial coal consumption, SO2 emission, acid rain occurrence, sulfation rate, etc, features of changes of atmospheric SO2 are disclosed, and main contribution to atmospheric SO2 pollution is concluded as iron and steel industrial point sources. Through technical improvement in iron and steel companies, SO2 emission has been gradually reduced, which has met Class I requirements of State Environment and Air Quality Standard (GB3095-1996). It can be concluded that for small iron and steel industrial city with single industrial structure, the main atmospheric pollutants come from industrial point sources, which are crucial for control and treatment of atmospheric SO2 pollution.
