AIR DISPERSION MODELLING FOR VEHICULAR EMISSION IN VADODARA CITY

ENVIRONMENTAL ENGINEERING

Vehicular exhaust is one of the important sources of air pollution. As per study 70% air pollution caused by vehicular activity, in India. Vadodara city is a Tehsil, having more than 1.9 million populations. In last decades the vehicular density has dramatically increase, with the increase of populations. In this situation traffic is one of the big problems in this fast generation. Air pollutants from vehicle exhaust like HC, CO, NOx, and PM will cause lots of dieses in human being, like stroke, chronic pulmonary dieses, heart dieses, lung cancer, respiratory infection, etc. & in the city every year more than lacks of vehicles are registered in regional transportation office. This study involves estimation of the vehicular air pollutants in the city by doing traffic survey and air quality modelling using AERMOD (USEPA) software. The result of the study is Isopleths of the various pollutants, which represent the pollution level in the traffic zone and various area of city based on 24 hour maximum ground level concentration µg/m3 in ambient air quality of Vadodara city.
