ABSTRACT
Increased economic growth, urbanisation and substantial rise in automobile vehicles has contributed towards the elevated levels of air pollution in major cities in Pakistan. A one week study was conducted by using passive samplers to assess NO concentration in occupational built environments at two most congested and populated sites of Lahore. Both sites 2 were located on the busy roads of Lahore. At Site-I the highest concentration was in outdoors followed by corridor and indoor. While at Site II all the sampling location were indoors and level were comparable to that of outdoor levels at Site I. The results suggest the likely contribution of ambient sources in exposure to indoor NO in educational and other 2 occupational built environments in urban centres. 2 implications, particularly, in urban areas.
