Abstract

The aim of this study is to analyze the IAQ concentrations of school rooms. In this study we measured and characterized IAQ at 440 school rooms from May 2009 to November 2012. At some school rooms, the $PM_{10}$ concentrations exceeded the IAQ guidelines ($100{\mu}g/m^3$) of the Ministry of Education. $CO_2$ concentrations at high schools were 1.18 and 1.06 times higher than that of the elementary and middle schools, respectively. $CO_2$ concentrations of some school rooms were exceeded the IAQ guidelines (1,000 ppm). Moreover, TBC concentrations at elementary school rooms were 1.23 and 1.33 times higher than that of the middle schools and high schools, respectively. TBC and HCHO concentrations did not exceed the IAQ guidelines. The classroom/non-classroom ratio of $PM_{10}$ was 1.06, while that $CO_2$ was 1.04, HCHO was 0.62, and TBC was 1.16.

본 연구는 우리나라 일부 학교의 실내공기질 현황을 조사 및 평가하고, 학생들이 쾌적한 교육 환경에서 생활할 수 있는 관리 방안으로 활용하는데 기여하고자 한다. 학교별 실내공기질를 분석한 결과, 일부학교의 경우 $PM_{10}$은 학교보건법 기준 농도인 $100{\mu}g/m^3$을 초과한 것으로 나타났다. $CO_2$는 고등학교가 초등학교와 중학교의 농도보다 각각 1.18배, 1.06배 높은 수준으로 나타났으며(p<0.01), 일부 학교에서 학교보건법 기준 농도인 1,000 ppm을 초과한 곳도 일부 있는 것으로 나타났다. HCHO는 학교별로 유의한 차이를 나타내지 않았다. TBC는 초등학교가 중학교와 고등학교보다 각각 1.23배, 1.33배 높은 수준을 보였으나(p<0.01), 전체적으로 학교보건법 기준 농도인 $800CFU/m^3$ 이하의 농도 수준을 보였다. 전체학교의 교실(Classroom)과 비교실(Non-classroom)의 농도비를 분석한 결과, $PM_{10}$은 1.06, $CO_2$는 1.04, HCHO는 0.62, TBC는 1.16으로 나타났다.
