- Recent epidemiological and toxicological studies have suggested that sulfur components of aerosols may present a serious health hazard. The chemistry, transformation, and stability of various sulfur oxidation states in aerosols produced by point sources emitting SO2 and aerosols is presently not well understood. The research being conducted under this contract is designed to identify concentrations of sulfite, sulfate, trace metals, and nitrite species in particulates produced by smelting and fossil fuel industries, establish the conditions (metal content, fuel type, SO/sub 2/ levels, acidity, temperature, humidity) and mechanism(s) of sulfite formation and study the stability of the various sulfur species in the ambient atmosphere. Research completed to date has resulted in the development of techniques for the above listed speciation problems and for the speciation of acid components of aerosols. Studies have been conducted to determine the ambient rate of oxidation or formation of metal-sulfite and organic-sulfite complexes in a copper smelter and a steel mill plume. Similar studies in the plume of a coal-fired generating station were inconclusive due to sampling problems.
