Sulfur oxide

Sulfur oxides (SOx) are a group of chemical compounds composed of sulfur and oxygen. The most common sulfur oxides are sulfur dioxide (SO
2
) and sulfur trioxide (SO
3
). Sulfur oxides are produced naturally through volcanic activity and are also released into the atmosphere from human activities like burning fossil fuels and industrial processes.
