Recently, Indoor air quality(IAQ) in workplace, residential environments and schools has been concern of people, scientists and related the public. And so in Seoul has recognized the healthy effect related to IAQ in schools. Therefore, the objective of this study reported in this article were to measure and compare the perception of IAQ of selected air pollutants at three different schools in Seoul. We performed a questionnaire survey of 400 students about their awareness for the importance of IAQ in our school. And we measured the IAQ of 3 schools considering as site region, construction year and studying level. The indoor air pollutants and parameters such as temperature, relative humidity, respirable particulate matter(PM10). formaldehyde(HCHO), total bacteria counts(TBC), carbon dioxide(C0₂), and noise were monitored in indoors. In results, all most response of occupant has recognized the awareness of IAQ at schools. The PM10. TBC and Noise level of all schools were higher than the standard of the public 150㎍/m³ and 500 CFU/rn³, the level formaldehyde(HCHO) was below 0.1 ppm of the healthy guideline of Korea And the concentration of CO₂ were investigated below 1,000 ppm of the standard implying ventilation in 2 schools except for 1 school(c school). Finally. the control of most important pollutants of IAQ in school were PM 10. TBC and Noise. Therefore, it can be concluded that the indoor air quality of selected 3 schools studied was perceived as acceptable. it is recommended that the government related IAQ was suggested the guideline and control of lAQ problems in schools. and all member relating school need to be effort to reduce the exposure of sources to undesirable indoor pollutants such as Particlate and Noise.
