|
This study aims to investigate the indoor air quality by analyzing PM10 concentration and metallic elements collected from
high school( classroom, science room, assembly room). PM10 concentration of a classroom, a science room, and an assembly hall during the research period was 87.7 ㎍/m3, 75.3㎍/m3, 64.6㎍/m3, respectively. Si of PM10 had highest concentration with 15,427 ng/m3 followed by Na which had 7,205 ng/m3, and the order was Si>Na>Ca>Mg>Fe>K in the classroom. PM10 concentration of a classroom and a science room was each 104.8 ㎍/m3 and 75.3 ㎍/m3 during the semester and PM10 concentration of a classroom and an assembly hall was each 80.9 ㎍/m3 and 64.6 ㎍/m3 during the summer vacation. Based on PM10 and metallic concentration at a classroom on day of week, the concentration of Friday was highest with 112.0 ㎍/m3, and that of Monday was lowest with 65.3 ㎍/m3.
