Characterization and source apportionment of wintertime aerosol in a wood-burning community
Abstract The continuing upsurge in residential wood combustion has raised questions about potential adverse effects on ambient air quality. A study to investigate the effects of wood-burning emissions on ambient aerosol concentrations was conducted in Waterbury, Vermont, from January to March 1982. Data on total, inhalable and respirable particles (24-h averages) were collected at a central monitoring site and augmented with similar measurements at two auxiliary stations. Mass concentrations were determined gravimetrically and selected samples were analyzed for elemental composition (XRF), polycyclic aromatic hydrocarbons (GC/MS, HPLC), and organic and elemental carbon (thermal-optical method). In addition, continuous data from an integrating nephelometer and a meteorological data acquisition system were collected at the central site. This paper presents results of organic and elemental characterization of wintertime aerosol and examines several different source-apportionment methods, focusing on the contribution of residential wood combustion to measured ambient concentrations.
