도로 인접 어린이집 보육실의 실내공기질 주간변화 특징

Abstract

The number of children who use day-care centers is increasing. Most indoor air quality (IAQ) management has been based on daily average pollutant concentrations measured once a year. A more comprehensive management of IAQ is needed to protect children’s health from air pollutants in day-care centers. In this study, we investigated the weekly variation of air pollutant concentrations in a nursing room of a day-care center located at the roadside for a week in June of 2014. Average concentrations of CO2, PM10, black carbon, and total surface area of lungdeposited particles during nursing time of the day-care center were 510 ppm, 27.8 µg/m3 , 1.87 µg/m3 , and 30.6 µm2 /cm3 , respectively, with a similar diurnal pattern shown on weekdays.
