다중이용시설 어린이집의 실내공기질 현황 분석

This paper analyzed the results of indoor air quality (IAQ) measurements for a total of 283 daycare centers in 2018. The measured IAQ types are 10 pollutants(CO2, TVOC, Radon, HCHO, CO, NO2, Mold, total airborne bacteria, PM10 and PM2.5) corresponding to the maintenance and recommendation standards of the Enforcement Rules of IAQ. The standards were revised twice on Oct. 18, 2018 and Feb. 13, 2019, and the standards were tightened for PM10 and PM-2.5. The measurements results show that the indoor conditions of the daycare centers met the 2018 criteria of IAQ in most pollutants items. However, for the post-revision criteria, PM10 exceeded the standard of 8% and PM-2.5 exceeded the standard of 9% for day care centers. Therefore, it is necessary to drive additional improvements for such daycare centers in order to meet the criteria of the revised IAQ standards to be enforced in July of 2019.
