A Survey of Distribution for Indoor Air Pollutants in Classrooms of Some Elementary Schools
Abstract
This study was surveyed to evaluate and recognize the distribution characteristics of indoor airpollutants(IAPs) such as the total volatile organic compounds(VOCs), formaldehyde(HCHO), PM10, carbondioxide(CO2), nitrogen dioxide(NO2), ozone(O3) and radon in 10 elementary schools located in urban, rural,and industrial complex area from November 2005 to February 2006. The average concentration of IAPs were117.9㎍/㎥ as in PM10, 1,971ppm as in CO2, 486.6㎍/㎥ as in TVOC. These chemical's concentration wasexceeded the indoor air standards of the Department of Education in Korea. The indoor concentrations ofozone and toluene was lower than that of outdoor and other pollutants showed the opposite tendency. Inschools located industrial complex area, the outdoor concentration of TVOC was higher than that of urbanand rural area. Based on the results above, PM10, CO2, TVOC have to be in the order of priority to improvethe indoor environment in school. Also it should be performed in the detailed survey considered by theseasonal variation because this study showed cross-sectional results.
