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).
