AIR POLLUTIONS EFFECT AND CONTROL METHODS IN FOUNDRY INDUSTRIES
Abstract
The development of science and technology leads to environmental problems in both developed and developing countries. Air pollution is one of these problems. The impact of air pollutants on human health has become a major issue. Air pollutant means any solid, liquid or gaseous substance (including noise) present in the atmosphere in such concentration that may or tend to be injurious to human beings, other living creatures, plants, property or the environment in general. Air pollution emanates from many sources, stationary sources such as factories, power plants, smelters and smaller sources such as dry cleaners and degreasing operations, mobile sources such as cars, buses, planes, trucks, and trains; anthropogenic activities and naturally occurring sources such as windblown dust and volcanic eruptions. Air pollution has been aggravated by development that typically occurs as countries become industrialized growing cities, increasing traffic, rapid economic development and industrialization, and higher levels of energy consumption. In air pollution is widespread in urban areas where vehicles are the
major contributors and in a few other areas with a high concentration of industries and thermal power plants. Vehicular emissions are of particular concern since these are ground level sources and thus have the maximum impact on the general population.
