Sulfur dioxide (SO2) is a chemical compound with the formula SO2. It is a colorless gas with a pungent, suffocating odor. Sulfur dioxide is produced by the burning of fossil fuels, particularly coal and oil, and by volcanic eruptions. It is also a byproduct of industrial processes such as smelting and sulfuric acid production.

In the atmosphere, sulfur dioxide can react with water, oxygen, and other chemicals to form sulfuric acid and sulfurous acid. These acids can then fall to the earth as acid rain, which can damage forests, lakes, and buildings. Sulfur dioxide is also a major component of particulate matter, which can cause respiratory problems and other health issues.

Sulfur dioxide has been used in a variety of industrial applications, including as a preservative for dried fruits and as a bleaching agent for paper and textiles. However, due to its harmful effects on human health and the environment, its use has been increasingly restricted.

In many countries, strict regulations are in place to limit sulfur dioxide emissions from power plants and other industrial sources. These regulations have helped to reduce the amount of sulfur dioxide in the atmosphere, but it remains a significant air pollutant in many parts of the world.
