Abstract
High PM concentrations in classrooms, which indicate poor ventilation conditions and the increasing particulate matter in urban outdoor air, have in particular, been identified as primary causes of poor indoor air quality in schools. In this study, 16 secondary schools were selected in Ogbomoso, and the collection of PM2.5 was performed in morning and afternoon and in the presence and absence of students. The concentration levels of PM2.5 concentration ranged from 14.4 to 58.5g/m3 for indoor and 8.2 to 70.1g/m3 for outdoor, PM10 concentration ranged from 83.5 to 348g/m3 for indoor and 48 to 282.3μg/m3 for outdoor in the presence of students while PM2.5 concentration ranged from 7.4 to 27.3μg/m3 for indoor and 5.7 to 20.3μg/m3 for outdoor, and PM10 concentration ranged from 55.8 to 291.5μg/m3 for indoor and 38.8 to 203.9μg/m3 for outdoor in the absence of students.
