Abstract

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 resultsof 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 can influence the Canyonlands sampling site. The results indicate that the variability in the ratios of these various species to SOx from the various regional sources is large enough to provide useful input to a receptor based, chemical mass balance sourceapportionment of SOx at the receptor sites. The chemical mass balanceanalysis is given in the final paper of this series. The ratio of SAS:SOx varies by a factor of 25 in emissions from various coal-fired power plants. The concentrations of lead and arsenic relative to sulfur oxides is also variable in emissions from different coal-fired power plants. The ratio of particulate selenium and total fluoride to SOx in emissions from these coal-fired sources is relatively constant. Emissions from source regions containing smelters are high in Se, As and Pb. Emissions from source regions containing fluoride ore processing industries have a high F-Total: SOx ratio.
