INDOOR AND OUTDOOR AIR QUALITY INVESTIGATION AT DORMITORY IN THE UNIVERSITY IN BEIJING, CHINA IN THE FALL
Eighteen dormitories, naturally ventilated, in a certain university in China were chosen for investigation of indoor air quality and the relationship of indoor and outdoor air quality in the fall. Parameters, such as temperature, relative humidity (RH), air velocity, carbon monoxide (CO), carbon dioxide (CO2), particulate matters (PM1, PM2.5, PM10, TSP), and TVOC were monitored at indoors and outdoors intermittently. Indoor CO concentrations of the most dormitories were lower for no indoor sources. Indoor CO2 concentrations often exceeded 1000ppm in the condition of the doors and window closed indicating inadequate ventilation. Indoor particulate matters concentrations were affected by outdoor vehicle emission. The indoor/outdoor (I/O) ratio of CO and particles were less than 1 generally, and the I/O ratio of CO2 and TVOC were higher than 1 generally.
