Sulfur Dioxide | American Lung Association
Sulfur dioxide (SO 2) is a gaseous air pollutant composed of sulfur and oxygen. SO 2 forms when sulfur-containing fuel such as coal, petroleum oil, or diesel is burned. Sulfur dioxide gas can also change chemically into sulfate particles in the atmosphere, a major part of fine particle pollution, which can blow hundreds of miles away.
