Determination of sulfur speciation in industrial aerosols in an SO/sub 2/-rich environment. Summary progress report, 15 June 1976-14 June 1979

Technical Report ·
OSTI ID:6504688
The research being conducted is designed to identify concentrations of S(IV), 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 formation of these S(IV) species and study the stability of the various reduced 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-S(IV) and organic-S(IV) 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. Experiments in plumes of coal and oil-fired power plants have been conducted to determine the effects of aerosol trace element content, fuel type, humidity, temperature, SO/sub 2/ concentration, and aerosol acidity on the formation and stability of S(IV) constituents in aerosols. Studies were conducted in the summer of 1978 to determine the ambient concentrations of the species in the rural Northeast US.
