This study was conducted to contribute to the basic data for decisions on environment policy improvement in health promotion for students in elementary, middle and high schools. This study was carried out to investigate the extent of indoor air pollution in elementary, middle and high schools in residential, traffic congestional and industrial areas. The concentrations of major indoor air pollutants(carbon monoxide, carbon dioxide, respiratory particulate, radon) and thermocircumstance (temperature, relative humidity, intensity of illumination) indices were observed from June to August 2000. As results of the survey, the mean values of thermocircumstance in school were 26.94±1.15℃ of temperature, 68.88±5.31% of humidity and 268.26±164.60 Lux of intensity of illumination. The mean concentrations of carbon monoxide, carbon dioxide, respiratory particulate were 8.36±0.29ppm, 547.66±175.58 ppm, 36.23±48.39 ㎍/㎥, respectively. These values were lower than those of the indoor environmental standard on the first clause of Article 45 of public utilization service notified public hygiene of the Ministry of Health and Social Affairs. The mean concentration of radon was 20.07±17.95 Bg/㎥. Which was below the U.S. EPA radon action level.
