Volatile organic compounds from used building materials in a simulated chamber study
AbstractBuilding materials emit volatile organic compounds (VOCs) indoors. They may also adsorb compounds so that an equilibrium with indoor air is reached. Samples were taken from the floor, walls, and ceiling of one room in a seven-year-old preschool building. They were placed in a small climate chamber for a period of 41 days. Samples from the air in the room and the chamber were analysed by gas chromatography and mass spectrometry, and about 60 compounds were identified. The composition of organics in the room air was reestablished in the chamber the first day. Since most of the compounds disappeared within 2 to 23 days, they are believed to have been adsorbed from the room air onto the material surfaces. During the last 10 days, 17 compounds remained at constant concentrations, implying that they are representative of the building material samples.
