| Abstract | Abstract Studies have shown that volatile organic compounds (VOC) emitted from architectural materials are potentially important indoor air pollutants in office buildings. In this study, we investigated emissions of VOC from 15 adhesives, both solvent- and water-based, that are used to construct and finish interiors of buildings. Adhesives were applied to an inert substrate and dried for 7 to 14 days. Vacuum extraction and cryogenic trapping of volatiles with analysis by gas chromatography/mass spectrometry were used for the qualitative and semiquantitative determination of emissions of VOC. Emission rates of VOC were determined with a simple air exposure apparatus and collection of volatiles on charcoal adsorption tubes. Quantitative analyses were performed by gas chromatography with flame ionization detection. The major compounds emitted by the adhesives were toluene, styrene, and a variety of cyclic, branched, and normal alkanes. The emission rates ranged from below the detection limit of 0.1 μg g −1 h −1 for an individual compound for some adhesives to approximately 700 μg g −1 h −1 of total alkanes for two water-based adhesives. The potential impacts of adhesives on indoor air quality were evaluated by applying a steady-state ventilation model which assumes well-mixed air to a hypothetical office space. The model results suggest that the two water-based adhesives are potentially important sources of indoor organic pollutants. More detailed studies of adhesives and other architectural materials are warranted to identify sources of contaminants and to develop source control strategies. |
