Organic fuel burned at thermal power stations contains harmful impurities, which are ejected into the environment as gaseous and solid components of combustion products and adversely affect the atmosphere and water and the whole biosphere. The atmosphere is also contaminated by waste gases of various industrial plants, exhaust gases of transport vehicles, abuse of agricultural chemicals and other contamination sources which are due to human activities. In India, by the turn of the century, about 70,000 MW of thermal power will be generated using high ash content coal. The environmental pollution due to thermal power generation will increase beyond acceptable limits unless stringent measures based on Environmental Protection Act, 1986 are strictly enforced. Causes of Thermal Pollution The thermal power stations use thousands of tons of low quality (high ash content) coal per day. These power stations and other industries have completely changed the nature and socio­economic order of the region. The natural rocky hills are disappearing due to heavy quarrying. Tall chimneys and gigantic machines emit a cloud of dust with fly ash and smoke containing high level of acid forming oxides of sulphur and toxic fluorides and huge quantity of highly toxic cement particles which find easy foothold on plant leaves and human lungs. The products of complete burning of fuel in thermal power plants mainly consist of carbon dioxide, water molecules, nitrogen, sulphur dioxide and S03 anhydride (sulphur trioxide) and ash. At high temperatures existing in the flame core of high power boilers, the nitrogen of fuel and air may partially be oxidized to form nitrogen oxides. Nitrogen dioxide dissociates in the presence of sunlight to nitric oxide and atomic oxygen. The latter combines with molecular oxygen to reform ozone (03). The concentration of ozone in polluted atmosphere often goes up 10 to 20 times the natural ozone level (0.02-0.03 ppm). With incomplete combustion of fuel in furnaces, carbon monoxide hydrocarbons (CH2, C2H4) etc. and some carcinogenic substances are additionally formed. Among many carcinogenic substances, of highest importance, as regards their intensity of action, are polycyclic aromatic hydrocarbons, in particular, benzapyrene. The highest quantity of benzapyrene is formed under the conditions when air is deficient and complete combustion cannot occur. Nitrogen oxides, even in low concentrations, can irritate respiratory organs, destroy equipme and materials, and promote the formation of smog and impair visibility. Sulphur is present iii solid fuels in three forms: as inclusions of pyrite FeS2; Sulphur in molecules of the organic ma of the fuel; and sulphate sulphur. Upon combustion of a fuel, almost all the sulphur contained in it passes to flue gases in the form of S02 and S03 oxides. Pollutants in the effluents of thermal power stations and natural admixtures undergo complex processes of transformations and reactions. Deposited on the ground, they are washed down by atmospheric precipitates and reach the solid and water basins. The hot fuel gases can be effectively removed in a powerful upward flow through high stacks and ejected into the atmosphere at a substantial height where they will be mixed with higher layers of the atmosphere. Before ejecting the fuel gases and ash into the atmosphere, however, the modern state of gas purifying techniques makes it possible to reduce appreciably the concentration of impurities in waste gases. Electrostatic precipitators are employed to ensure a high degree of gas cleaning. With any method of fuel and waste gas purification, however, a certain quantity of impurities remains in the effluent gases. If harmful impurities have been dispersed in the atmosphere to concentrations not exceeding the scientifically found norms, their presence in the atmosphere has practically no effect on the living nature. Toxic substances both of natural and industrial (antropogenic) origin can produce deleterious effects on the whole complex of biosphere. The biosphere comprises of the atmospheric layer near the earth's surface and the upper layers of the soil and water basins. Though the natural sources of atmospheric pollution are sometimes more powerful than the anthropogenic ones, the latter are of great importance since they are responsible for atmospheric pollution in densely populated areas. The main contributor to atmospheric pollution is the combustion of mineral fuels, especially the thermal power plants. The relative contribution of a particular industry to atmospheric pollution may vary with the rate of growth of the industry.

The Effect of Over Exploitation of Natural Resources and Industrialisa­tion The environment refers to natural things around us which sustain our life, such as the atmosphere of the earth, fresh and healthy air and drinkable water etc. To define environment we may say that it is an outer physical and biological system in which man and other organisms exist with many interacting components. The most recognised among these components include the rocks, minerals, soils and waters, the land and its present and potential vegetation, the animal life and potential for livestock husbandary and the climate etc. There is a close interaction among these various components which seem to produce some kind of equilibrium in the scheme of nature which is termed as ecological balance. This interaction of various components is known as ecosystem. This ecosystem is related with environmental factors. The various living organ­isms of this environment get heat and energy from the sun to make a closely knit ecocycle. Organisms of this ecosystem may generally be divided into three categories: 1. Producers, 2. Consumers, 3. Decomposers. Producers mostly belong, to the category of plants that make their food by the inorganic substances by themselves in the presence of light. Consumers particularly include animals including human being, that de­pend for their food on other organism including plants, and the decomposers come in the category of bacteria and fungus etc. that decompose the organic substances present in dead plants and animals. The system is useful to man. A perfect ecological balance cannot be expected in the wake of growing industrialisation as owing to this, pollution of environment becomes inevitable. The environment has “carrying capacity”, or the amount of pollution or damage an environment can sustain without further degradation. A lake that is 5 times larger than another one can carry roughly 5 times the pollution load. If the loads of pollution are not minimised or environment upgraded to an extent that it will be able to carry them, the environmental degradation will inevitably worsen. By the misuse, abuse and uncontrolled use of resources both natural and otherwise have upset the equilibrium between human activity and nature. Over-exploitation of natural resources in the name of industrialization is posing a great danger to the ecosystem. This danger may be understood in following two ways: 1. Physical Environment. 2. Human Environment. Physical Environment consists of all constituents of natural origin like physiography-, climate, vegetation, soil, water bodies, wild animals and minerals. Human Environment consists of all elements having a human touch in their origin. Such elements include all manifestations of human activities. Of course natural resources cannot be confined to the physical mani­festation of nature, it also includes the entire environmental scenario-the carrying capacity of nature, the extent up to which the nature can accommo­date.
