The indoor environment is characterized by a surface area-to-volume ratio that is far larger than outdoors. Studies have revealed that the inner surfaces of buildings, furnishings, house dust, and aerosol particles are home to thousands of different semi-volatile organic compounds and play an important role in human exposure to environmental contaminants through both inhalation and dermal uptake pathways. Our recent work has shown that condensed phases within buildings can act as an important reactive center and reservoir for trace gases. In addition, the composition of the condensed phase can strongly influence the partitioning of semi-volatile gases. This presentation will cover several key examples of how detailed chemical measurements of indoor environments can support new insights into the physical chemistry occurring at the interface of gaseous and condensed phases indoors.
