Sulfur dioxide (also sulphur dioxide in British English) is the chemical compound with the formula S O 2.It is a toxic gas with a burnt match smell. It is released naturally by volcanic activity and is produced as a by-product of the burning of fossil fuels contaminated with sulfur compounds and copper extraction.
Sulfur dioxide is most noteworthy as an environmental pollutant. It is formed when materials containing sulfur are burned, and is thus an important air pollutant, especially in the vicinity of smelters and plants burning soft coal or high sulfur oil.

Sulfur dioxide (SO 2) is formed when fuel containing sulfur, such as coal and oil, undergoes combustion and during petroleum refining. SO 2 dissolves in water vapor to form acid, and interacts with other gases and particles in the air to form sulfates and other respirable particulates.

The Clean Air Act requires EPA to set national ambient air quality standards (NAAQS) for sulfur dioxide and five other pollutants considered harmful to public health and the environment (the other pollutants are ozone, particulate matter, nitrogen dioxide, carbon monoxide, and lead).
Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur: S + O 2 → SO 2 , ΔH = −297 kJ/mol To aid combustion, liquefied sulfur (140–150 °C) is sprayed through an atomizing nozzle to generate fine drops of sulfur with a large surface area.
Sulfur dioxide generating pads (or sheets) are packed in containers of grapes post-harvest to control various fungal rots. These products contain sodium metabisulfite (also spelt metabisulphite), which reacts to moisture in the grape container, releasing sulfur dioxide, thereby preventing grapes being affected by various fungi during storage and transportation.
