Abstract

A comparative study of indoor and outdoor air quality was carried out in five schools in Hong Kong. The schools have different modes of ventilation and encompass different locations. The study involved a 5-day indoor air quality (IAQ) monitoring at each school during the winter months (November 97-January 98). Temperature, relative humidity (RH), carbon dioxide (CO), sulfur dioxide (SO), nitrogen oxides (NO), total volatile organic compounds (TVOC), respirable particulate matter (PM-10), formaldehyde (HCHO), and bacteria (total counts) were measured at both indoor and outdoor locations simultaneously. Temperature, RH, CO, and PM-10 were monitored for 24-hour periods, while grab samples were used to measure other pollutants before and after school hours.
