sulphur oxide

Any of a family of chemical pollutants derived from combustion of fossil fuels.

sulfur (IV) oxide

An irritating gas used in industry to manufacture acids and as a bactericide and disinfectant. It is derived from burning fuels that contain sulfur and from volcanic emissions. When absorbed by water on particulates in the atmosphere, the gas is further oxidized (e.g., by light and NO2) to form sulfuric acid (H2SO4. It is a major component of air pollution.
