An experimental study is described in which atmospheric aerosol measurements at Allegheny Mountain in southwestern Pennsylvania were used to search for interrelationships of SO/sub 4/(-), percentage SO/sub 2/-SO/sub 4/(-) conversion, meteorological properties, rainfall, visibility, light scattering, SO/sub 2/, aerosol mass, H(+), NO/sub 3/, various trace elements, and rainfall H(+) and SO/sub 4/(-). The selected woodland location is in the area of maximum SO/sub 4/(-) concentration in the northestern U.S. The results obtained show that aerosol H(+) and SO/sub 4/(-) were uniquely correlated with each other and with light scattering, that the light scattering was entirely attributable to SO/sub 4/(-), and that SO/sub 2/ is evidently not related to any other parameter. It is concluded that the SO/sub 4/(-) at Allegheny Mountain stemmed from transport, with or without SO/sub 2/ oxidation, from westward nonurban sources of some kind that were sources of very little else in the aerosol.
