Purpose: The purpose of this study was to investigate the concentrations of volatile organic compounds at elementary, middle, and high schools in Ulsan and its surroundings.
Methods: To assess the hazardous chemicals of the 66 classrooms in the 22 schools, the 6 volatile organic compounds such as TVOCs (Total Volatile Organic Compounds), benzene, toluene, xylene, ethyl benzene and stylene were measured and analyzed from the beginning of May to the end of December, 2009.
Results: The mean concentrations of TVOCs in the elementary schools were higher than those of middle and high schools, and multi-purpose classrooms was higher than that in general ones. The benzene and toluene level in schools in Dong-Gu in the vicinity of assorted industrial complexes was higher than that of schools located in other districts around the Ulsan Metropolitan Area.
Conclusion: In case of schools in Ulsan Metropolitan Area, elementary school, schools in Dong-Gu, and multipurpose classrooms over general classrooms should be given a high priority for the management of volatile organic compounds.
