Combustion-Related Organic Species in Temporally Resolved Urban Airborne Particulate Matter.

ABSTRACT: Accurate characterization of the chemical composition of particulate matter (PM) is essential for improved understanding of source attribution and resultant health impacts. To explore this we conducted ambient monitoring of a suite of 15 combustion-related organic species in temporally resolved PM _2.5 samples during an ongoing animal exposure study in a near source environment in Detroit, MI. All of the 15 species detected were above the method detection limit in 8 hour samples. This study focused on two molecular classes: Polycyclic Aromatic Hydrocarbons (PAHs) and Hopanes measured in samples. Of the 12 PAHs studied, benzo[b]fluoranthene (169 pg m^-3), benzo[g,h,i]perylene (124 pg m^-3), and benzo[e]pyrene (118, pg m^-3) exhibited the three highest
