The change in concentration of these parameters for a period of five years from 1991 to 1995 is monitored and various causal factors arc discussed. The values of suspended particulate matter exceed the prescribed standards for commercial and residential areas for most of the time, while they were mostly within limits in the Industrial areas. The concentration of SO, and NOx are far below the prescribed maximum limits at all places.
