Sources of sulfur dioxide pollution In 1963, more than 23 million tons of sulfur dioxide were discharged into the atmosphere of the United States. The fossil-fueled power plant is the chief contributor to sulfur dioxide emissions and accounts for over 40% of the total emission.
Sulfur dioxide (SO2) is a gas that is prevalent in crude oil, coal, and ore that contains common metals like aluminum, copper, zinc, lead and iron. Where does it come from?O2 is formed when fuel-containing sulfur is burned and when gasoline is extracted from oil, or when metals are extracted from ore. Once it is released into the atmosphere, SO2 dissolves in water vapor to form acid (acid rain).
