Vehicular Air Pollution and Air Quality Indices

Vehicle emissions are responsible for about two third of air pollution in urban areas. The main pollutants emitted by vehicles include carbon monoxide, oxides of nitrogen and sulphur, hydrocarbon, lead, ozone & suspended particulate matter. These pollutants have harmful effects on human health & ecology. Poor air quality increases respiratory disorders like asthma & bronchitis & increases the risk of life-threatening diseases like cancer. In India, the impact of pollution from vehicles is increasing day by day due to rapid increase in population & modernization. Impact of vehicle pollution is more in cities due to urbanization. Kota is the fastest developing city of Rajasthan having more than 650000 registered vehicles that shows large number of vehicles & associated impacts of emission through vehicles on polluting air. To study the vehicular pollution in Kota city, both off-line & on-line methods have been used. In on-line method, vehicle gas analyzer is used to measure five parameters O2, CO2, HC, CO & ¿ and in off-line method, high volume air sampler is used for air monitoring. Hope, the book will prove its usefulness to concerned students, researchers & others.
