General description

Dimethyl sulfide (DMS) is formed in sea water due to various biological processes. It is the major sulfur containing gas generated by ocean and liberated to the atmosphere. Its quantitative determination during DMS generation in seawater tanks during phytoplankton bloom simulations has been reported. Mechanism of its photochemical oxidation in atmosphere has been described.
