Young children health problem were reported in a Korean daycare centers and supposedly attributed to thepresence of air pollutants. This study attempted to characteristics of carbonyl compounds exposure of youngchildren at the indoor spaces. The characteristics associated with the major indoor pollutants exposureincluded seasonal variation, and room location inside a daycare centers. As the results of investigation fordaycare centers, the mean concentrations of formaldehyde, acetone, and acetaldehyde in daycare centerswere 38.3㎍/m3, 33.9㎍/m3, 13.6㎍/m3, respectively. The indoor space carbonyl compounds concentrationswere both higher for the summer than for the other seasons. The temperature and relative humiditymeasured along with the volatile organics measurements temperature and relative humidity increase volatileorganics levels. This last suggestion is further supported by the correlations of the carbonyl compoundsmeasured for daycare centers. Significant correlations between carbonyl compounds were exhibited for boththe temperature and humidity, with at least p<0.05. The concentrations of formaldehyde in classroom werehigher than lobby or dining room. Therefore, controlling indoor air pollutants exposure in daycare centershould be given a high priority so as to minimize the potential sources of air pollutants in indoor space.
