The largest single commercial producer of DMS in the world is Gaylord Chemical Corporation, which is a significant economic component of the paper industry of Bogalusa, Louisiana.ĭimethyl sulfide is flammable and an irritant. It can also be oxidized by natural or artificial means to dimethyl sulfoxide, (DMSO), which has several important solvent properties. It also has a use as a food flavoring component. It is also used in a range of organic syntheses, also being a side product of Swern oxidation. In addition it is used to control dusting in steel mills. In industry it is used in petroleum refining and in petrochemical production processes to control the formation of coke and carbon monoxide. Recent research suggests that marine bacteria are reducing the amount of this important climate cooling gas given off from our seas. Through this interaction with cloud formation, the massive production of atmospheric DMS over the oceans may have a significant impact on the Earth's climate. DMS is also produced naturally by bacterial transformation of dimethyl sulfoxide (DMSO) waste that is disposed of into sewers, where it can cause environmental odor problems.ĭMS is oxidized in the marine atmosphere to various sulfur-containing compounds, such as sulfur dioxide, dimethyl sulfoxide (DMSO), dimethyl sulfone, methane sulfonic acid and sulfuric acid.Īmong these compounds, sulfuric acid has the potential to create new aerosols which act as cloud condensation nuclei. While Andrew Johnston, of the University of East Anglia, has characterized DMS as being the "smell of the sea", it would be more accurate to say that DMS is a component of the "smell of the sea," another being pheromones of algae called dictyopterenes. Emission occurs over the oceans by phytoplankton. 1 Natural sources and link with climateĭMS is the most abundant biological sulfur compound emitted to the atmosphere.
