This study was conducted to investigate the actual condition of fine particles (PM2.5) pollution and to verify thenecessity of managing PM2.5 in the indoor environment of public use facilities in Gyeonggi-do. As a result, itwas found that PM2.5 concentrations measured for 24 hours ranged from 15.9 to 113.5 μg/m3 and averaged 42.5 μg/m3, and for 6 hours, ranged from 20.4 to 167.1 μg/m3 and averaged 65.6 μg/m3. Average concentration was highestin subway stations, followed by nursery schools and indoor parking lots. 49 of the 55 sites investigated exceededthe 24hr-PM2.5 standard specified in WHO guidelines (25 μg/m3). The ratio of PM2.5 to PM10 was 70.2% for 24hrand 70.7% for 6hr on average. This means that PM2.5 tends to account for a large proportion of the total particulatepollution in the indoor environment, and that it is essential to control fine particulate matter in order to reducetotal particulate matter in the indoor environment. In addition, it was found that the time to be sampled and totalsampling time are one of important factors which affect PM2.5 concentration in indoor air quality; therefore, I thinkthat it is necessary to concretely specify the time to be sampled and maximum range of total sampling time inthe test method of PM2.5. Recently, regulations on PM2.5 in indoor environments have been strengthened in othercountries due to its high risk to human health; however, there is currently no enforceable regulation in Korea. Given that PM2.5 is more harmful to human health than PM10, it is urgently necessary to establish proper policiesand regulations to control PM2.5 in indoor environments.
