1Air in urban society. Vehicular transportation vitiates the environment

1Air is one of the five basic natural ingredients of life system. Air pollution 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 crowed cities or urbanisation are the main outcome of the modern civilisation. These are contributing to environmental pollution (Sharma, 2004). Primary air pollutants are emitted directly into the atmosphere and secondary air pollutants are formed in the atmosphere by reactions among two or more pollutants. The concentration of air pollutants depends not only on the quantities that are emitted directly from air pollution sources but also on the ability of the atmosphere to either absorb or disperse these emissions along with the various physical and chemical dissipation processes liable toremove pollutants through self purification process. During transportation of the industrial products and vehicular movement on non-metal led roads, fine dust particles settled on the ground gets airborne and cause diseases. Transportation is the prime source of mobility in urban society. Vehicular transportation vitiates the environment by emanating obnoxious and toxic pollutants in the surrounding atmosphere which results in serious health hazards to community and objects. Air pollution is posing disastrous health problems in some of the biggest cities of the world and has now become an inescapable part of urban life everywhere (De, 1993). As we know air pollution is basically the presence of undesirable foreign substances which can produce harmful effects on man and his environment (Bardhwar et al., 2004). The exhaust fumes of vehicle contain major pollutants such as Oxides of Nitrogen (NOx), Carbon Monoxide (CO), Hydrocarbons and Particulate Matter. Many power plants are accompanied with severe air pollutionproblems. CO2, SO2, NOX and fly ash are the four major pollutants of concern in thermal power plants emissions. Hence the present study was proposed to estimate the air pollution load in term of SPM, RPM, CO, Oxides of Nitrogen and Oxides of Sulphur at different stages in and aroundBalgopalpur Industrial Estate.BackStart Over
