| Conclusion |
|
 Presence of dangerous unnatural ingredeints causing imbalance in the ecosystems and health hazards to human beings and animals is called pollution. |
| |
 Pollution is mainly found in air, water, soil, food and sound. |
| |
 Major human activities like industries, agriculture, health care, transport, dwelling and energy generation are the causes of pollution. |
| |
 Many industries like textile, paper, steel, sugar, petroleum, food, chemical and cement industries cause air pollution, water pollution and soil pollution. |
| |
 Industrial pollutants include gases like methane, cyanides, carbon tetrachloride, carbon disulphides, carbon monoxide, hydrogen disulphides, hydrochloric acids, ammonia, sulphur dioxide as well as multiples of liquid / solid compounds. |
| |
 Modern agriculture - encouraging the large scale of fertilizers and pesticides - is primary cause of drinking water pollution. |
| |
 Transport has been the main reason for air pollution in most cities. Vehicular trffic releasing carbon monoxide, sulphur dioxide, nitrogen dioxide has caused large scale air pollution in cities. |
| |
 Pollution of air is the major cause human health problems such as respiratory problems, lung / throat, cancer etc. Pollution of water is also the main cause of health problems like gastero - enteritis formation of ulcers, tumors. |
| |
 Health problems due to pollution range form simple vomiting and skin irritations to intestinal cancer, brain tumors, from simple fever to fatal hepatitis, from throat irritation to deadly heart diseases. |
| |
 Foods that we eat are polluted because of use of pesticides, use of polluted water or microbial activities. Many persistent pesticides enter food chains and accumulate in bodies at a larger concentrations. |
| |
 Soil pollution by various solids and liquids has created imbalances in soil ecosystems besides creating number of ecological hazards in cities and villages. |
| |
 Control of pollution has been a formidable challenge to human civilization. As the pollution grows with the civilization and growing population, the control of pollution is more challenging. |
| |
 Several measures have been adopted, suggested imposed in industries, in agriculture and urban dwellings to control the pollution. |
| |
| However fast growing population and high capital requirement are the major problems being faced to implement the scientific methods of pollution control. |
