Sulphur Dioxide

Sulphur Dioxide (SO2) is a gaseous oxide that results from the combustion of sulphur containing fossil fuels and also from the smelting of sulphur containing ores. Typically SO2 is emitted from electrical utilities and other industrial facilities. Sulphur dioxide is also a precursor to sulphate aerosols, commonly contained within fine and ultrafine particulate matter, and to the formation of acid rain.
