Sulfur dioxide (SO2) emissions are a primary contributor to acid rains. They are produced by the combustion of fossil fuels such as coal, oil, orimulsion, municipal solid waste, automobile tires and many industrial processes such as gasoline refining, cement, paper, glass, steel, iron, and copper production.

Short-term exposures to SO2 can harm the human respiratory system and make breathing difficult. Children, the elderly, and those who suffer from asthma are particularly sensitive to effects of SO2. SO2 emissions that lead to high concentrations of SO2 in the air generally also lead to the formation of other sulfur oxides (SOx). SOx can react with other compounds in the atmosphere to form small particles. These particles contribute to particulate matter (PM) pollution: particles may penetrate deeply into sensitive parts of the lungs and cause additional health problems.
