During January-March of 1990 a study was conducted to determine the sources of sulfur oxides present at Canyonlands and Green River, Utah. Samples were collected at these two receptor sites and at several sites intended to characterize the chemical composition of air masses reaching the receptor sites from various geographical regions. The results of the sampling program have been given in the first paper in a series of three papers. In this paper, the concentrations of spherical aluminosilicate (SAS) particles, total fluoride, and particulate selenium, arsenic and lead are combined with meteorological data to obtain source fingerprints for the ratios of these species to SOx from the various regional sources that...
