Abstract
Dimethyl sulfate (DMS), (CH3O)2SO2, has been shown to be carcinogenic in different animal systems and is considered to be a probable human carcinogen. Even though the presence of DMS in the atmosphere is a potential human health concern, there is little known about its atmospheric formation or degradation. For example, it has been inferred but not proven, that DMS can be formed in the atmosphere from the reaction of methanol with sulfuric acid. This has led to questions concerning the potential impact that emissions from large vehicle fleets operating on methanol fuel might have on atmospheric DMS levels. To remove some of these uncertainties we have undertaken a systematic study of the homogeneous gas phase chemistry of DMS, in which we have addressed the following questions: (1) How is DMS formed in the atmosphere, and is methanol involved? and, (2) what is the fate of DMS in the atmosphere?
