초록

This study evaluated the indoor air quality of 26 government offices located in Seoul. The pollutant samples were taken from Jan. 13th to Jan. 29th and Feb. 20th to Feb. 23rd, 2010 in the offices. The target indoor pollutants for this study were PM10, formaldehyde, carbon monoxide, carbon dioxide, total bacteria counts, total volatile organic compounds, radon, nitrogen dioxide, ozone, and asbestos which were controlled by the indoor air quality law for the multiple-use facilities management. The results of this study showed that some pollutants of the 38.5%offices exceeded the standards of the air quality guideline. The correlation analysis of the same pollutants between indoor and outdoor represented that NO2 (r=0.629, p⁄0.05) and O3 (r=0.459, p⁄0.01) were significant, however,PM10 and CO were not. The correlation analysis between different pollutants showed that CO and TVOC (total volatile organic compounds: r=0.724; p⁄0.01), CO and NO2 (r=0.674; p⁄0.01), HCHO and humidity (r=0.605;p⁄0.01), CO2 and TVOC (r=0.534; p⁄0.01), TBC (total bacteria counts) and Asbestos (r=0.520; p⁄0.01) were significant. The energy-saving system of government buildings in winter caused under-ventilated and poor air quality. This study suggests that the concentrations of radon and CO2 should be used as an indicator for monitoring indoor air quality and maintaining effective ventilations.
