Volatile organic compound conversion by ozone, hydroxyl radicals, and nitrate radicals in residential indoor air: Magnitudes and impacts of oxidant sources.

ABSTRACT: Indoor chemistry may be initiated by reactions of ozone (O₃), the hydroxyl radical (OH), or the nitrate radical (NO₃) with volatile organic compounds (VOC). The principal indoor source of O₃ is air exchange, while OH and NO₃ formation are considered as primarily from O₃ reactions with alkenes and nitrogen dioxide (NO₂), respectively. Herein, we used time-averaged models for residences to predict O₃, OH, and NO₃ concentrations and their impacts on conversion of typical residential VOC profiles, within a Monte Carlo framework that varied inputs probabilistically. We accounted for established oxidant sources, as well as explored the importance of two newly realized indoor sources: (i) the photolysis
