Air Pollution
Air pollution is not a disaster. Its a causes of disaster. Now a days air pollution become a growing problem in the world.
Basically in the modern world the air pollution problems has been started from the Factories Act and the Motor Vehicles Act prohibit excessive smoke emissions.
Use of natural gas has been suggested to replace fuel wood in brick kilns and other uses.
Contrary to the level of public awareness, there is a total absence of ambient air quality data. There is no air quality monitoring station in the country.
Industries, thermal power plants and motor vehicles are among the major contributors to air pollution. According to air quality surveys, the levels of sulphur dioxide and oxides of nitrogen maintain the air purity.
Chlorofluorocarbons (CFCs) and halons are a class of chemical compounds which are used extensively in refrigerators and air conditioning plants, in the manufacture of polystyrene foams, in electronic industries, and as sprays in cosmetic and medical industries.
The process of modernization is also slowly contributing to air pollution. The proliferation of trucks and cars have perceptibly increased the level of air pollution in certain pockets of urban areas.
The cement factory emits five to six tonnes of dust every day. The factory has an emissions rate forty times higher than that of similar factories in West Germany. However, apart from journalistic investigations, the volume of scientific evidence on air pollution is extremely limited in the country.
The important measures taken to control air pollution, standards of exhaust from motor vehicles have been prescribed for phased implementation. Air pollution episodes have been witnessed in many instances, but facilities for monitoring air pollution are lacking in these enterprises. Only a handful of industries have installed pollution control equipment, many of which are not operated effectively. This technology is mostly imported. The staff handling such equipment is often inadequately trained, particularity in the state enterprises, resulting in inefficient use of equipment.
