ANALYSIS OF AQI DUE TO TRANSPORTATION & IT’S PREVENTIVE MEASURES

Abstract

Urban air pollution is a major problem across the country. More than 80% of cities in India where air quality is
monitored do not meet the standard of air quality prescribed by the Government of India. Transport sector has
always been a significant contributor in emission estimates of cities. The source apportionment studies
conducted in the six major cities of the country have shown that transport has significant contributions in PM2.5
and NOx concentrations. Moreover, the lower height of release of vehicular emissions leads to higher exposure.
WHO has recently classified diesel exhausts as Class-I carcinogens. Air pollution in India has increased rapidly
due to population growth, increase in the numbers of vehicles, use of fuels, bad transportation systems, poor
land use pattern, industrialization, and above all, ineffective environmental regulations. Sulphur Dioxide,
Nitrogen Dioxide, Particulate Matter are some of the pollutants which are contributing to environmental
pollution. Purpose of this paper is to review the literature relating to the analysis of ambient air quality of some
Indian cities and compare the same with Indian National Ambient Air Quality Standards. Also discuss of the use
of Air Quality Index (AQI), seasonal variation in concentration of air pollutants. Use of health impacts due to
increase in the concentration of air pollutants in Indian cities. With rising air pollution levels and deadly health
risks, leading cities have developed clean air programs using the AQI. The AQI is the key tool in programs for
protecting communities and triggering response actions. By calculating the AQI we will find the remedial
measures to curb the pollution level from our Ahmedabad city zones. To examine the impact of transportation
air pollution levels and to investigate the effects of air pollution on related health impacts, socio-economics and
welfare of urban city
