Carbonyl sulfide (COS) is a colorless, odorless, non-flammable, and very lightweight gas. It is most commonly known for its role in air pollution, as it is one of the most abundant sulfur compounds in the atmosphere, and can adversely affect human health and the environment.

COS is mainly produced by natural sources, such as plants and marine organisms. It is also produced as a byproduct during industrial processes, such as the burning of fossil fuels and the production of plastics. Anthropogenic sources of COS include the burning of coal, oil, and gas, as well as the manufacture of sulfur-containing products, such as hydrogen sulfide and sulfur dioxide.

In terms of human health, COS has been linked to an increase in respiratory and cardiovascular diseases, as well as a decrease in lung function. It has also been associated with an increased risk of eye, throat, and nose irritation.

In terms of the environment, COS react with other air pollutants to create ozone, a pollutant that can damage vegetation, reduce crop yields, and increase the risk of ground-level ozone formation. It can also react with nitrogen oxides to form sulfuric acid and nitric acid, two pollutants that can damage ecosystems and contribute to acid rain.

In terms of its uses, COS can be used in the production of chemicals, such as hydrogen sulfide, sulfur dioxide, and sulfuric acid, as well as in the production of sulfur-containing fertilizers. In addition, it can be used as a feedstock in the manufacture of a variety of other products, such as plastics, textiles, and pharmaceuticals.
