A Survey on the Indoor Air Quality of Some School Classroom in Gyeongbuk area
Abstract
This study was performed to investigate the characteristics of indoor air quality (IAQ) in elementary andmiddle schools in Gyeongbuk area from July to November 2006 . The measurements of indoor air pollutantswere made to cover such components as PM-10, CO2, CO, NO2, O3, HCHO, TVOC, TBC, and Radon fromschool classrooms. The results of this study can be summarized as follows: all of them were less than IAQstandards of Korea. The mean concentration were measured by 43.0 ㎍/㎥ (PM-10), 745 ppm (CO2), 56.1 ㎍/㎥(HCHO), 350 CFU/㎥ (TBC), 0.026 ppm (O3), 0.6 ppm (CO), and 59.2 ㎍/㎥ (TVOC). Radon was not detectedin all surveyed classrooms. The I/O ratio of PM-10 was 0.8∼1.4, while that for HCHO was 5.7∼9.0.Therefore, it was concluded that the indoor pollution of formaldehyde was very serious in classroom.
