Air is one of the five basic natural ingredients of
life system. Air contamination may be described as the presence of air
pollutants in the atmosphere to such an extent that they cause deleterious
effect. Rapid industrialization year after year, introduction of faster mode of
transport and sprouting up large crowded cities or urbanisation are the outcome
of the modern civilisation. These are contributing to environmental
contamination. Primary air pollutants are emitted directly into the atmosphere
and secondary air pollutants are formed in the atmosphere by reactions of two
or more pollutants. The fixation of air pollutants relies not just on the
amounts that are emitted directly from air pollution sources but also on the
capacity of the climate to possibly absorb or scatter these emanations
alongside those different physical and chemical dispersal techniques at risk to
remove pollutants through self purification process. During transportation of the
industrial products and vehicular movement on non-metal led roads, fine tiny
particles settled on the ground gets airborne and result in ailments.
Transportation is the prime source of mobility in urban society. Vehicular
transportation vitiates nature by emanating obnoxious and toxic pollutants in
the encompassing environment which brings about serious health hazards to the
community and objects. Air contamination may be posing terrible wellbeing
issues in a few of the most amazing urban communities of the universe and has
now become an inevitable part of urban life. As we know air contamination is
fundamentally the presence of undesirable foreign substances which can produce
harmful effects on man and his environment. The exhaust fumes of vehicle hold
numerous significant pollutants for example, Oxides of nitrogen (NOx), Carbon
Monoxide (CO), Hydrocarbons and Particulate Matter. A significant number of
energy plants are accompanied with air contamination issues. CO2, SO2, NOx and
also fly ash are four significant pollutants for worry over thermal power
plants emissions.
