This study was performed to investigate the characteristics of indoor air quality(IAQ) in 91 public facilities from September 2004 to March 2005 in the Honam province(Chonnam, Gwangju). The measured air pollutants are PM₁?, formaldehyde(HCHO), CO, CO₂, and total suspended bacteria(TSB), the maintenance standard materials of IAQ management law established by ministry of environment in Korea(MOE). We also surveyed establishment and operation of ventilation equipment. It was measured 1.2 m~1.5 m on the floor between 8 o’clock AM and 7 o’clock PM. As the result, PM₁? and CO was showed the highest concentration, 188.89 ㎍/㎥, 8.67 ppm, at the indoor parking. The concentration of HCHO was the highest in large store and steamer room. The concentration was respectively 118.70 ㎍/㎥ and 113.21 ㎍/㎥. The concentration of CO₂ was the highest at the reading room of the library on the condition of natural ventilation. The concentration of CO₂ was 1,816 ppm and higher than the IAQ standards established by MOE. The TSB was just measured in the hospital and silver town. It was the highest at the admission room of hospital. The concentration of TSB was 766 CFU/㎥. The public facilities of this study were not exceed each maintenance standards except CO₂ but it was surveyed that the management will be needed about some air pollutant according to target facilities.
