Methane sulfonic acid reactions atmosphere

Dimethyl disulfide (DMDS), CH3SSCH3, is released mainly from marine biology and biomass burning. The rate constant of the OH reactimi is very fast, 2.3 X 10 ° cm molecule s at 298 K, and the atmospheric lifetime is very short within a few hours. The reaction is thought to give methane sulfonic acid (MSA) directly (Barnes et al. 1994) as. 

Dimethyl sulfoxide has been measured in the atmosphere and laboratory studies indicate that in the atmosphere this compound will be rapidly oxidized by reaction with the OH radical. The oxidation of DMSO remains a subject of continued investigation. In the atmosphere, DMSO may be converted into dimethyl sulfone, SO2, or methane sulfinic acid.
