Rapid industrialization is a primary requirement for developing countries in order to enhance living status of its population and contributing to sustainable growth. Industrialization deteriorates the environment. Key atmospheric pollutants are particulate matter, oxides of nitrogen, oxides of sulphur and RSPMs. India ranks fifth globally in overall emissions and is projected to rank higher as the economy grows.
W.H.O defines “air pollution as the presence of materials in the air which are harmful to the living beings when they cross their threshold concentration levels”. The Ohio Environmental Protection Agency [EPA] provides the definition of "Air pollutant" or "air contaminant" as particulate matter, dust, fumes, gas, mist, smoke, vapor or odorous substances, or any combination there of. Airborne particles smaller than 10 micrometers, called as particulate matter less than 10 μm [PM10s] cause serious respiratory problems in humans, other pollutants which are harmful are oxides of sulfur and oxides of nitrogen.
