source of air pollution in the urban areas. Vehicular exhaust‚ a by-product of fuel combustion contains potentially lethal chemical compounds such as carbon monoxide‚ oxides of nitrogen and sulphur and unburnt hydro carbons. Vehicular pollution traces its source to fossil fuels that are burnt in mobile sources (all categories of motorized vehicles). During the past few years‚ various steps have been taken to reduce vehicular emissions and its effect is evident on ambient air quality
