Poor indoor air quality is found to be related to the prevalence of respiratory disorders in children. School aged children spend 6-8 hours in classroom. Therefore, air quality and its health risk in classroom need to be considered. In this study, we measured the level of PM10 in three junior high schools and its health risk assessment. The mean level of indoor PM10 in three schools were 0.215 mg/m3, 0.075 mg/m3, 0.229 mg/m3 respectively. The level of indoor PM10 in two schools was higher than outdoor. The exposure of PM10 in two schools was estimated to inflict health risk therefore it needed to be maintained at a safe threshold of 0.142 mg/m3. This study concluded that indoor air quality in all junior high schools was poor and estimated to inflict health risk on students.
