Title: Ozone reactive chemistry on residential surfaces

Abstract

The heterogeneous chemistry of ozone on interior latex paint was investigated in a tube flow reactor. The emissions of several polar volatile organic compounds (VOCs) including organic acids, aldehydes and ketones were measured while a glass tube coated with latex paint was exposed to clean air and two different concentrations of ozone. Formic and acetic acid were not found to be generated via ozone reactions; however, both were found to offgas from the latex paints. Formaldehyde, acetaldehyde and acetone were found to be produced by ozone reactions. It was found that formaldehyde is produced in sufficient quantities to impact indoor concentrations. Additionally, ozone, organic acids, aldehydes and ketones were measured over an approximately 24 hour period in 4 residences during the winter of 1993 and in 9 residences during the summer of 1993. Environmental variables such as indoor and outdoor temperature and indoor and outdoor relative humidity were recorded. It was found that the VOC emission rate was correlated with both the environmental variables and the ozone removal rate. A combined ozone removal rate and environmental variable model indicated that both these factors are important, suggesting that polar VOCs may be formed by ozone reactions.
