ABSTRACT
According to a report of World Bank, the annual health cost to India was up to Rs.5500 crores due to air pollution, of which, the health cost of air pollution in Delhi alone was found to be about Rs.1000 crores. Transport sector alone accounts for about 70% of the air pollution in our cities, most of which is in close proximity to the breathing zone, hence it is essential to chalk out a long term plan to combat this menace. Decision making must first involve proper analysis of the merits as well as demerits and the effectiveness of the various methods. Simulation is one such method of analysis by predicting the expected results using suitable models. For sake of simplicity certain assumptions had to be made. Vehicular sources’ contribution to ambient air pollutant concentration is taken to be 70%. Pollution load of CO, NOX and PM (per day) is calculated and by using the proportionate model, ambient air concentration of these pollutants in different cases is calculated. Thus, once the ambient air concentration in different cases is calculated, it can be used to find out which case suits best according to National Ambient Air Quality Standards. Moreover several other comparisons were made such as the reduction in pollution load of various pollutants by applying each option which could help to identify the problem areas and using them some important conclusions could be drawn out that would help the authorities in planning the policies related to automobiles, fuels and other related things.
