Abstract
This study aims to investigate the indoor air quality by analyzing $\small{PM_{10}}$ concentration and metallic elements collected from high school(classroom, science room, assembly room). $\small{PM_{10}}$ concentration of a classroom, a science room, and an assembly hall during the research period was 87.7 $\small{{\mu}g/m^3}$, $\small{75.3{\mu}g/m^3}$, $\small{64.6}$$\small{{\mu}g/m^3}$, respectively. Si of $\small{PM_{10}}$ had highest concentration with 15,427 $\small{ng/m^3}$ followed by Na which had 7,205 $\small{ng/m^3}$, and the order was Si>Na>Ca>Mg>Fe>K in the classroom. $\small{PM_{10}}$ concentration of a classroom and a science room was each 104.8 $\small{{\mu}g/m^3}$ and 75.3 $\small{{\mu}g/m^3}$ during the semester and $\small{PM_{10}}$ concentration of a classroom and an assembly hall was each 80.9 $\small{{\mu}g/m^3}$ and 64.6 $\small{{\mu}g/m^3}$ during the summer vacation. Based on $\small{PM_{10}}$ and metallic concentration at a classroom on day of week, the concentration of Friday was highest with 112.0 $\small{{\mu}g/m^3}$, and that of Monday was lowest with 65.3 $\small{{\mu}g/m^3}$.
