Moyers, J. L.

A research program of sampling, analysis and evaluation of atmospheric trace components was established in and around Tucson, Arizona in order to identify relationships between atmospheric physical and chemical parameters and air quality conditions. Large particle airborne soil or crustal materials were found to dominate the particulate population in both the urban and rural southern Arizona atmosphere with over a dozen of the measured species directly attributable to these sources. Nonsoil species in general appear to be well mixed and contained predominantly in the small particle population. This suggests that these species are generated by gas to particle conversion processes and distant or diffuse anthropogenic and natural sources. The acid-base nature of airborne gases and particles appears to control the gas and particle distribution of several volatile species (HCL, HBr, HNO, NH/sub 3/) and to largely define the particulate sulfate speciation (Primarily (NH/sub 4/)/sub 2/SO/sub 4/). Large seasonal fluctuations, consistent with the climatology and meteorology for the area under investigation, were observed. Multivariate statistical techniques were used to significantly enhance the capabilities for data evaluation.
