Several analytical techniques for the determination of organic S(IV) compounds in environmental samples were evaluated, the structure of organic S(IV) was identified as bis-hydroxymethyl sulfone, new analytical procedures for analysis of dimethyl and monomethyl sulfate in particulate samples was developed, and these and existing techniques were applied to the study of the formation of sulfate, the sulfone, and methylated sulfate species in the flue lines and plumes of an oil and a coal-fired power plant. 1. Inorganic S(IV) compounds and bis-hydroxymethyl sulfone are generally not present in primary emissions from coal or oil-fired plants but are formed in the plumes emitted by these facilities; 2. The formation of sulfate from SO/sub 2/(g) in the daytime follows kinetics which are first order in SO/sub 2/(g) and are temperature dependent; 3. The formation of sulfate from SO/sub 2/(g) in the plume of an oil-fired power plant in a fog bank is about 30% SO/sub 2/(g) hr/sup -1/. The fog bank reaction may be catalyzed by co-emitted oxidants; 4. Dimethyl and/or monomethyl sulfate have been shown to be present in both flue line and plume samples from coal- and oil-fired power plants; and 5. Methylated sulfates increase in concentration in aerosols during plume transport in the plumes of the power plants studied.
