What is sulfur dioxide?
Sulfur dioxide (SO2), a colorless, reactive gas, is produced during the burning of sulfur-containing fuels such as coal and oil, during metal smelting, and by other industrial processes. Major sources include power plants and industrial boilers. Generally, the highest concentrations of sulfur dioxide are found near large industrial sources.
Sulfur dioxide is a colorless gas with a pungent odor It is a liquid when under pressure Sulfur dioxide dissolves in water very easily It cannot catch fire. Sulfur dioxide in the air results primarily from activities associated with the burning of fossil fuels (coal, oil) such as at power plants or from copper smelting In nature, sulfur dioxide can be released to the air, for example, from volcanic eruptions.
