  • The identification of combustion sources with polycyclic aromatic hydrocarbons (PAH) source signatures in the chemical mass balance model (CMB) was examined in this study. Three combustion sources, residential wood combustion, gasoline and diesel vehicular emissions, were investigated. Source PAH emissions were characterized and each source emission was expressed as a source pattern with a specific concentration. A normalized concentration method which takes advantage of the pattern characteristic was developed to provide effective separation in two-source conditions. When PAH reactivity is introduced, a CMB model with a continuous stirred tank reactor (CSTR) decay factor (Friedlander 1981) was used for ambient samples. Reasonable predictions were obtained in two case studies in which PAH data exist and source receptor modeling was undertaken using other tracers.
