Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO2. It is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide.
Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus Acid Rain. This is one of the causes for concern over the environmental impact of the use of these fuels as power sources.
Sulfur dioxide is sometimes used as a preservative for dried apricots and other dried fruits owing to its antimicrobial properties, and it is sometimes called E220 when used in this way. Sulfur dioxide is an important compound in winemaking, and is designated as parts per million in wine, E number: E220.
