Weekly average concentrations of 45 volatile organic compounds (VOC) were determined in living rooms of more than 300 homes divided in three age groups. Repeated measurements of the same VOC were carried out in 4 homes every second week for half a year, and in 11 newly built homes before and during occupancy. The results of this exploratory study showed that virtually all VOC had higher indoor than outdoor concentrations; a wide range in indoor VOC levels was observed. Clusters of solvent type compounds were tentatively identified, which suggests the existence of common sources. The repeated measurements showed fairly stable indoor levels for some compounds in some homes, while large variations were observed for other compounds and other homes. During the first few months of occupation, the straight-chain and aromatic hydrocarbon concentrations were generally higher than in older homes. It is concluded that most of the measured VOC have both consumer products and building materials as indoor sources. The highest observed concentrations in the occupied homes were probably the result of incidental occupant activities. |
