Description

A highly toxic colorless gas with a sulfide odor. Carbonyl sulfide is formed during production of carbon disulfide and the manufacture of some plastics. Significant amounts of carbonyl sulfide are also released during the combustion of coal, fossil fuels, natural gas, biomass, and refuse. Non-human activity production of carbonyl sulfide comes from volcanos, salt marshes, and soils. It is naturally removed from the atmosphere by plants, photolysis, soil absorption, water hydrolysis, and microorganisms.
