Sulfur dioxide (SO2) is the most common, simplest and irritating sulfur oxide. One of the major pollutants in the atmosphere. Volcanic eruptions spew the gas, and sulfur dioxide is also produced in many industrial processes. Because coal and oil usually contain sulfur, sulfur dioxide is formed when burned. When sulfur dioxide dissolves in water, it forms sulfurous acid. If sulfurous acid is further oxidized in the presence of PM2.5, sulfuric acid (the main component of acid rain) is rapidly and efficiently produced. This is one reason for concern about the environmental effects of using these fuels for energy.

1. Used as organic solvent and refrigerant, and for refining all kinds of lubricating oil.

2. Mainly used in the production of sulfur trioxide, sulfuric acid, sulfite, thiosulfate, also used as fumigant, preservative, disinfectant, reducing agent and so on.

3. Sulfur dioxide is a reducing bleach allowed in China. It has a strong inhibitory effect on food bleaching and oxidase in plant food. It is stipulated in China that it can be used for wine and fruit wine. The maximum usage is 0.25g/kg, and the residual amount should not exceed 0.05g/kg.

4. Industrial sectors such as pesticides, man-made fibers and dyes.

5. Used for the production of sulfur and as insecticides and fungicides.
