Description:
Samples from annular denuder systems (ADS) collected during the winter of 1985-1986 in Boise, ID, have been analyzed for acidic oxides of nitrogen and sulfur. The correlations between the data from the ADS and XRF measurements of Pb and K in the fine particles were examined to determine if any of the species collected by the ADS (e.g., HNO2, HNO3) would serve as receptor modeling tracers for the extractable organic matter (EOM) from mobile and/or woodburning sources. Results of these correlations will be discussed. The report also discusses the precision of the ADS measurements and compares results obtained with other measuring methods for similar species (e.g., XRF data for S with sulfate measured with the ADS). In addition, comparison of ambient concentrations of species measured with the ADS at the two monitoring sites in Boise will also be examined in relationship to the chemical properties of fine particles collected in Boise, ID and spatial homogeneity of gases and aerosols.
