With technological advancement humans have progressed, and along with this there has been a phenomenal increase in the number of vehicles. These vehicles drain our limited natural resources like petrol and diesel. They are also responsible for polluting the air and also for noise pollution. This section exposes this problem of vehicular pollution and how it is increasing dramatically with each passing day.
The genesis of pollution begins with the story of urbanization. Vehicular exhaust, a by-product of fuel combustion contains potentially lethal chemical compounds such as carbon monoxide (CO),
Traditionally, the most common air pollutants in the urban environment are carbon monoxide, Sulphur dioxide, nitrogen oxides, ozone, suspended particulate matter and lead. Incomplete combustion (burning) is the main cause of most pollutants. A broad study of the cities of the world indicates that urban air pollution has three primary sources: industrial pollution, domestic pollution and vehicular pollution.
In urban areas – both developing and developed countries, it is predominately mobile or vehicular pollution that contributes to air quality problem. All motor vehicles release pollutants into the air, mostly through the exhaust fumes that come out of the tailpipe when the engine operates. Tailpipe emissions are products of burning fuel in the vehicle’s engine, emitted from the vehicle’s exhaust system. The worst thing about vehicular pollution is that it cannot be avoided as the vehicular emissions are emitted at the near-ground level where we breathe.
CAUSES OF VEHICULAR POLLUTION
• High vehicle density in Indian urban centers.
• Older vehicles predominant in vehicle vintage.
• Inadequate inspection and maintenance facilities.
• Predominance of two stroke two wheelers.
• Adulteration of fuel and fuel products.
• Improper traffic management system and road conditions.
• High levels of pollution get better grades at traffic.
