Abstract
The usefulness of passive monitors in providing information on atmospheric nitrogen dioxide (NO2) levels in a tropical, urban environment is assessed from the results of an investigation which covers the University of the West Indies (UWI), Mona Campus. This is an area which is relatively small and in which the likely sources are fairly easily identified. The data obtained indicate that the method has a detection limit of about 1.0mg m-3 while the levels at individual sites range between about 6 and 86mg m-3. The main source of NO2 on the Campus appears to be traffic exhaust, though two unusually high values, which are unlikely to be traffic related, are recorded during one of the preiods of observation. These are thought to be due to malfunctioning boiler units at the University Hospital. The passive monitors are found to be quite suitable for providing the baseline data on gas pollutants, that is part of the information needed to allow general assessment of the state of pollution of the atmosphere....
