Wildland-Urban Interface (WUI) Smoke Yields of Nonmethane Organic Gases from Combustion of Small-Scale Residential Building Surrogates.

ABSTRACT: At the wildland-urban interface (WUI) structural fires can generate nonmethane organic gases (NMOGs) from burning urban fuels like structural lumber, plastics, and carpet. These NMOGs can contaminate nearby homes and affect indoor air quality. NMOGs have been quantified extensively from biomass burning, but few measurements exist of yields from structure fires. We calculated yields of 201 NMOGs generated from burning small-scale residential building surrogates. We also constructed surrogates of different sizes and stick packing densities to modulate air ventilation and simulate how reduced oxygen conditions in enclosed fires might affect NMOG yields. We find that reduced aromatics (e.g., benzene, naphthalene) show notably higher yields from combustion of the surrogates compared to biomass,
