Vehicular pollution has grown at an alarming rate due to growing urbanisation in India. The air pollution from vehicles in urban areas, particularly in big cities, has become a serious problem. The pollution from vehicles has begun to tell through symptoms like cough, headache, nausea, irritation of eyes, various bronchial and visibility problems.
The main pollutants emitted from the automobiles are hydrocarbons, lead/benzene, carbon monoxide, sulphur dioxide, nitrogen dioxide and particulate matter. The main cause of vehicular pollution is the rapidly growing number of vehicles.
In India, the number of vehicles increased from 0.3 million in 1951 to 58.3 million in 2001-02. About half the vehicles are concentrated in 39 metropolitan cities (cities with population of over one million). The two wheelers are the major contributors of vehicular air pollution followed by four-wheeler (e.g., car, jeep, taxi etc.), trucks and buses in decreasing order of magnitude.
Delhi is a typical example of air pollution by vehicles. Table 9.6 shows that Delhi’s vehicular population increased from an insignificant of 2.17 lakh in 1971 to 44 lakh in 2004. Over 2.5 lakh vehicles were registered in Delhi in 2004—more than twice the number registered in 2003. Of the total vehicular population in Delhi in 2004, 13.37 lakh were four wheelers, 27.8 lakh two wheelers, more than 80 thousand autorickshaws, 18.4 thousand taxies, 26.9 thousand buses and 1.55 lakh goods vehicles. This figure is likely to rise to 60 lakh in 2011.
