Air pollution is one of a variety of manmade environmental disasters that arecurrently taking place all over the world. Air pollution may be defined as an atmosphericcondition in which various substances are present at concentrations high enough abovetheir normal ambient levels to produce a measurable effect on people, animals,vegetation, or materials. ‘Substances’ refers to any natural or manmade chemicalelements or compounds capable of being airborne. These may exist in the atmosphere asgases, liquid drops, or solid particles. It includes any substance whether noxious or benign; however, the term ‘measurable effect’ generally restricts attention to thosesubstances that cause undesirable effects. Air quality has deteriorated both due to humanactivities, and natural phenomenon such as wind blown dust particles etc.
