This study was performed to estimate the emission rate of volatile organic compounds (VOCs) and toevaluate the risk level affected by indoor air pollutants (IAPs) in 27 new apartments (prior to residence) inSeoul City from December 2004 to March 2005.The indoor air pollutants investigated in this study include formaldehyde, several aromatic VOCs (benzene,toluene, styrene, xylene, and ethylbenzene). All measurements were made based on the standard method ofMinistry of Environment in Korea. The indoor concentration levels for benzene, xylene, toluene, ethylbenzene,styrene, and formaldehyde have significant increase trend 5 hours after closing windows and doors. Levels ofair pollutants did not exhibit significant difference between living rooms and bedrooms. The air exchangerates by the concentration decay method using SF6 were 0.37 for low floor, 0.32 for middle floor, and 0.75for high floor. The emission rate showed the highest level in the middle floor and second one in the lowfloor, when estimated by the IAQ model for benzene, toluene, ethylbenzene, xylene, styrene, andformaldehyde. Considering the above result, it is suggested that the estimation of emission rate beconsidered when the new apartment is designed and constructed with respect to construction materials toemit low VOCs. Moreover, the related regulation should be established for IAQ management.
