A Study on Indoor Air Quality in School
Abstract
This study investigated the indoor air concentrations and the harmful effects on health by hazardous pollutantsin the normal classrooms and special classrooms of 132 elementary, middle, and high schools locatedin 13 sites in Chungnam from February 2006 to June 2007.The results obtained from this investigation are as follows.As the results of the survey on the indoor air quality, volatile organic compounds were higher in normalclassrooms(251.67㎍/m3) than special classrooms (181.59㎍/m3), and formaldehyde was significantly higher inspecial classrooms (34.22㎍/m3) than normal classrooms (24.61㎍/m3). With regards to the differences of pollutantdistribution among elementary, middle, and high schools, volatile organic compounds were the highestin elementary schools (210.79㎍/m3) followed by middle schools (207.79㎍/m3) and high schools (195.96㎍/m3), and formaldehyde was the highest in high schools (36.03㎍/m3) followed by elementary schools (29.84㎍/m3) and middle schools (29.16㎍/m3). With regards to the mean concentration of pollutants by school buildingage, VOCs were the highest in less than 1 year old classrooms (410.93㎍/m3), followed by less than 3 yearsold classrooms (156.52㎍/m3) and less than 2 years old classrooms (120.18㎍/m3). Formaldehyde was alsoinvestigated to be significantly higher in less than 1 year old classrooms (41.37㎍/m3) than 2 or 3 years oldclassrooms (31.50㎍/m3, 22.21㎍/m3, respectively).
