Sulfur and nitrogen compounds in urban aerosols
Some results are reported for sulfate, nitrate, and related ionic species taken from a detailed chemical and meteorological data base that has been accumulated for the New York subregion since 1976 (the data base is generally referred to as the New York Summer and Winter Aerosol Studies). Some of the experimental advances in sampling and analysis of aerosol sulfur and nitrogen compounds and related gases are described that offer promise for the measurement of all components of the atmospheric sulfate-nitrate-SO/sub 2/-NO(x)-NH/sub 3/ system with a time resolution of a few minutes. These advances include aerosol sulfur measurement by real-time FPD, gaseous nitric acid sampling and analysis, and continuous ammonia analysis.
