Abstract
This work investigates for indoor air quality particulate matter 2.5 microns (PM2.5) in classrooms of Science building at the Faculty of Science, Udon Thani Rajabhat University, Thailand. The study was determined from selected five classrooms and monitored by a dust track meter during the summer (April-May 2019) and rainy season (June–July 2019). PM2.5 concentrations in summer were found between 53.1±11.10 µg/m3, which over the maximum acceptable value PM2.5 for indoor air quality in office buildings (8 hours) by the Ministry of Public Health, Thailand (35 µg/m3), while in the rainy found only 25.6±4.99 µg/m3. This indicated summer was also possibly related to the thermal inversion phenomena, which often occurs in high and low temperatures between indoor and outdoor sites. The results showed the average PM2.5 concentration in laboratory rooms (43.2±9.36 µg/m3) was higher than that of the lecture rooms (32.71 µg/m3). This is because the activity of class occurred during the laboratory lesson time. Additionally, the outdoor source caused by air pollution from sugar cane combustion near Udon Thani University can be generated the high PM2.5 (Average 91.70±21.62 µg/m3). As because of this, PM2.5 generated by particles of these activities was the critical environmental problems in the Udon Thani city. The results show that new data in Udon Thani university for the air quality (PM2.5) based on concentrations from indoor air in classroom, including caused of PM2.5 pollution is emitted from outdoor pollution sources. It is well known that air pollution constitutes the most pressing environmental health risk and environmental problems. Therefore, the data of this study to benefit for the local government and environmental organizations to reduce or prevent the concentrations of many pollutants are influenced by local in Udon Thani city.
