Abstract
In this study, VOCs originating from vehicles were measured at 8 underground parking lots(two apartments,four department stores, and two large-scale marts) in Daejeon. The indoor air quality at underground parkinglots of the department stores and marts was affected by the availability of the ventilation facility and theiroperation frequency. At the underground parking lots with a ventilation facility, the maximum VOCsconcentration was 727㎍/㎥, and the minimum was 73.5㎍/㎥. The average concentration ratio of BTEX toTVOCs at the underground parking lots was almost constant, which was approximately 44.8%. TVOCs andBTEX were strongly correlated with a correlation coefficient (r) of 0.88. The relative ratio of benzene,toluene, ethylbenzene and xylene was 1 : 9.51 : 0.71 : 2.53, directly reflecting the influence of vehiclessources.
