The atmospheric sulfur chemistry was studied in airborne particulate samples collected from a lead smelter plume, a coal fired power plant plume and from rural areas of Indiana, Ohio and Pennsylvania. The mechanisms of conversion of SO/sub 2/(g) to sulfate, inorganic S(IV), organic S(IV) and methylated sulfates were studied as functions of atmospheric conditions and plume residence time. The rate of conversion of SO/sub 2/(g) to sulfate was dependent on temperature, ranging from 1-5%/hr. The conversion of SO/sub 2/(g) to particulate organic S(IV) is dependent on atmospheric water concentration, ranging from 0.5-1.7%/hr. Insufficient data were collected to obtain a rate of conversion of SO/sub 2/(g) to methylated sulfates. A fluorimetric method for the determination of alkylating agents in particulate samples is described. The limit of detection is 5.6 picomoles.
