Methanesulfonic Acid
Dimethyl sulfide (DMS) is the principal biogenic organic sulfur compound entering the atmosphere, where it undergoes light and chemical oxidation. Methanesulfonic acid (MSA), a strong acid that does not undergo photochemical oxidation, is produced by this oxidation and deposited on the earth`s surface, where it can be biodegraded as shown below ([http://www.ncbi.nlm.nih.gov/pubmed/8932698|Higgins et al., 1996]).
