Investigation of Molecular Composition and Phase Partitioning of Organic Particles and Gases in a Residential Environment with Natural Ventilation

Abstract

The Air Composition and Reactivity from Outdoor aNd Indoor Mixing (ACRONIM) campaign was launched to investigate the impact of natural ventilation (window opening and closing) on the chemical composition of indoor atmospheric particles and gases. Particles and gases were measured alternately inside and outside the residence with a suite of chemical instrumentation, including a Thermal desorption Aerosol Gas chromatograph (TAG). Compounds measured with the TAG were integrated and analyzed using Positive Matrix Factorization (PMF). A three-factor PMF solution provides insight into mechanisms driving changes in indoor particle and gas composition with natural ventilation, including enhanced volatilization of indoor-originating compounds and compound formation due to the influx of oxidants with opened windows.
