Materials- Part I: Experimental Results (RP-1097)

Three typical kinds of building materials (painted drywall, ceiling tile, and carpet) have been tested to study the effects of environmental conditions (temperature, relative humidity, and air velocity) on the sorption of volatile organic compounds (VOCs) by building materials. It was found that the effects of environmental conditions on sorption were insignificant for the painted drywall due to its weak sink strength as compared to the experimental uncertainty. The effect of relative humidity was generally small on the sorption of most compounds on ceiling tiles and carpet. However, the increase of temperature and air velocity may affect the amount of VOCs adsorbed by the ceiling tiles and carpet
