In order to recommend criteria for the administration law on indoor air quality, this study was conducted to examine the distribution and the concentration of indoor air pollutants (PM₁?, CO₂, CO, HCHO, TBC, NO₂, Rn, VOCs, asbestos, O₃) in public facilities in the Chung-Nam area. The concentrations of indoor air pollutants were obtained from sixty seven public facilities such as a cinema, an office, a restaurant, a theater and an academy. This study was performed from August to December, 2005. The results of this study showed that the concentrations of indoor air pollutants such as PM₁?, CO₂, CO, HCHO, TBC, Rn and O₃ were less than the recommended limits. However, the average concentration of VOCs was 521.73㎍/㎥ (GM : 221.69㎍/㎥), which was higher than the recommended limit of 400 ㎍/㎥. Moreover, the average concentration of NO₂ was 345.66ppb (GM : 69.95ppb), which was higher than the recommended limit of 50 ppb. The correlation between the concentrations of indoor air pollutants and the type of facilities with respect to CO₂, TBC and Rn was statistically low (p<0.05). However, the correlation was high in terms of the CO and O₃ concentrations (p<0.01). No relationship between the indoor air pollutants and the type of facilities was observed for PM₁?, VOCs and NO₂. The year of construction was compared to the concentrations of indoor air pollutants. Specifically, when the construction date was less than 3 years, the HCHO, VOCs and TBC concentrations were 44.75 ㎍/㎥, 555.07 ㎍/㎥and 337.79 CFU/㎥, respectively. These concentrations were 120 ㎍/㎥and 211.84 CFUl㎥ higher for VOCs and TBC than the concentrations obtained from the facilities more than 3 years. However, the concentration of HCHO was similar between the facilities older and younger than 3 years of age. Year, temperature, humidity and indoor air pollutant correlation analyses showed that temperature and humidity, temperature and TBC, temperature and O₃, PM₁? and NO₂, HCHO and VOCs, CO₂ and Rn had positive relationships. However temperature and Rn, humidity and CO₂, CO₂ and O₃, Orand Rn had negative relationships. Accordingly, it will be necessary to manage the factors affecting indoor air quality so that the residents can have a more comfortable and healthier living environment. Ultimately, the results of this study are expected to be utilized as baseline data.
