Purpose: The purposes of this study were: (a) to assess indoor air quality such as PM10, CO2 concentrations in child daycare centers, (b) to compare the levels with each standard, and (c) to identify teachers’ awareness of indoor air quality in child care centers.
Methods: Data were obtained from seventeen child daycare centers and ninety-eight teachers in a district of Seoul, from April 3 to May 12, 2009. Collected data were analyzed by SAS 8.2, and descriptive statistics, χ₂ test, student t-test, Pearson correlation analysis, and Spearman rank correlation were used.
Results: The mean of PM10 and CO2 level were 50.3㎍/m³ and 792.1ppm. Sixteen child daycare centers (94.2%) met the guidelines of the PM10 level, so did thirteen child daycare centers (76.5%) in the CO2 level. CO2 levels were significantly low in child daycare centers using air cleaners than those do not using them (t=-6.03, p<.001). Types of child daycare centers were significantly correlated to the levels of CO2, which public child daycare centers were low in CO2 levels than those of private child daycare centers (t=-2.54, p=.013). There was no significant correlation between teachers’ awareness and management attitude of indoor air quality while teachers’ awareness of indoor air quality significantly raised the frequency of carpet cleaning. Methods of cleaning routines were significantly correlated with PM10, and CO2 levels.
Conclusion: The PM10 and CO2 concentrations in child daycare centers were satisfactory. Those conditions are affected by general characteristics of child daycare centers and teachers’ attitude regarding management of indoor air quality.
