This study investigated and reported the results of the distribution of in air particulate matter concentration inside school classrooms where children, who are known to be environmentally vulnerable, spend the most time after home. The objective of this study is to provide basic data for future studies related to indoor air quality in Yeongwol county and studies for improving school environment. The study investigated the levels of the concentration distribution of PM10 and PM2.5 in classrooms at 19 different elementary schools based in Yeongwol county from December 12 to 19, 2016. In the classrooms of the elementary schools in Yeongwol county, the pooled average concentration of PM10 and PM2.5 was 11.9 μg/m³ and 4.2 μg/m³, respectively. These concentration rates were lower than those of PM10 and PM2.5 surveyed in classrooms of elementary schools based in other regions of Korea. Further, they did not exceed 100 μg/m³, the PM10 guideline concentration provided by the School Health Act. The study results revealed that the winter concentrations of PM10 and PM2.5 in air inside classrooms of elementary schools based in Yeongwol county were influenced more by indoor sources such as indoor residents rather than outdoor sources.
