Abstract

Indoor surfaces and the films on them play important roles in indoor air quality due to the high surface area to volume ratios in our homes. The chemical complexity of these films can be large, and this can increase after film formation as the chemicals in the mixture react and age on the surface. An improved understanding of the important chemical classes found in these films will help model predictions for partitioning of organic chemicals in indoor air. Here, we probe the chemical composition of extracts of indoor surface films using advanced mass spectrometry techniques. We compare the surfaces with measurements of aerosols and gases that contribute to the films to probe the effects of oxidative aging of the surface films compared to the sources for the films.
