Abstract

The purpose of this study was to assess an alternative method to characterize indoor environmentalfactors by multiple indoor and outdoor measurements. Using a mass balance model and regression analysis,penetration factor and source strength factor were calculated using multiple indoor and outdoormeasurements. This study was performed in 30 selected apartments in Seoul, Asan, and Daegu area whichwere constructed within 4 years and over 4 years, to measure the concentration of NO2 from July, 2004 toSeptember.The results of this study are as follows. The average concentration of NO2 in Seoul, Asan, and Daegu areain the apartment constructed within 4 years are nitrogen dioxide 48.01㎍/m3 and in the apartment over 4years are nitrogen dioxide 46.54㎍/m3. Mean ratios of indoor to outdoor NO2 concentrations are Seoul 0.99,Asan 0.83, Daegu 1.18. The deposition constant and the source strength of NO2 were 0.97±0.55 hr-1 and16.33±12.30 ppb/h, respectively. In conclusion, indoor environmental factors were effectively characterizedby this method using multiple indoor and outdoor measurements.
