Praise be to Allah, prayer and peace be upon His Messengers ..
At the outset we would like to explain why our choice of this particular subject to write it when we saw the state of the environment on progress in this wide world in general and especially our municipality. Have spread disease and many children died because of environmental pollution.
So we like to discuss this longstanding and pose solutions that we see fit. It may be beneficial to the reader when read. Nerj
Chapter I:
A - the definition of pollution: تعريـف التلوث:He knew where the pollution in different ways: that pollution is the development of materials in other appropriate ********s or that pollution of the environment (intentional or unintentional) with human excrement.
There are some definitions most detailed and accurate, such as the definition and Holstr Portoz, identified a comprehensive definition of pollution through the definition of pollution, polluter is a substance or effect leads to a change in the rate of growth species into the environment contrary to the toxins enter the food chain or contrary to the health or comfort or with the values of society.
And the intervention of contaminants to the environment in significant quantities of material in the form of waste and litter or spin-offs from industries or certain activities of man and usually involves pollution to dissipate energy (thermal, acoustic or vibration) and, in general, the pollution damage the vital functions of class (Biosphere) that surround the globe ... and this damage can be summarized as follows:
1 - harm to human health through pollution of air, soil, food, chemicals and other radioactive materials.
2 - damage to crops and plants, water, soil and animals.
3 - damage to the aesthetic aspects of the environment such as smoke, dust, noise and waste and garbage.
4 - damage that can not be felt only in the long run, but having a cumulative impact, such as cancers (materials that lead to cancer), radioactive materials and noise.

B - Types of pollution: أنواع التلوث :1 - food contamination:
Resulted in the overuse of agricultural fertilizers and pesticides to a number of adverse health and economic food for human consumption, and grew up as a result of the food contamination.
2 - Air pollution:
Air pollution occurs from different sources, which may be natural or the various activities of man, Vatabieip such as: storms and thunders and rain, earthquakes and floods. And contribute to the bulk of the rights of air pollution by sewage, waste and industrial waste, agricultural, medical and oil and petroleum products, pesticides and fertilizers, radioactive materials , and this might cause many damages to the ecosystem.
3 - Water pollution:
Down to the ground water in the form of pure, free of microbial pathogens or other contaminants, but as a result of the massive industrial development subject to several problems which turn into water unfit for drinking and consumption. One of the most examples of contamination of water including rain launched factory fumes and gases, As a result, created the so-called acid rain. The contaminated water in many different pollutants Vilut For example, remnants of sanitation and various chemical detergents and some mineral elements such as: lead, mercury, phosphates and nitrates, chlorine and oil.
4 - radioactive contamination:
Cause rights in air pollution differs from the known contaminants, a radioactive contamination, which is at present the most serious environmental pollutants. May show the impact of this pollution is rapidly and surprise on the organism, and it may take a long time to appear in future generations, and since the Second World War and so far present a person could use the radioactive materials in the production of dangerous nuclear and hydrogen bombs.

5 - ****l pollution:
The problem of pollution of toxic mineral elements in the present time the most important problems facing professionals in the field of environment, so they are of extreme health damage to human health. This problem was exacerbated as a result of the rapid development in various industrial fields, for example, the proportion of carbon monoxide in the air. The element of lead have been observed increase constantly as a result of the burning of many fuels and vehicles.
6 - Noise:
Increase the intensity of noise in the modern world significantly, no longer limited to major cities and industrial zones, but arrived to the countryside, and a person can make a noise through the establishment of methods to modern cars, railways, aircraft and agricultural machinery industry. And did not hand over the homes of noise when he mocked rights all means of modern technology for the well-being of radio, television, cleaning tools, kitchen utensils, etc., in other words, the noise has invaded the few remaining ****ters for silence in the world. And perhaps even the end of this century will not find any room still exists to turn to if he wants to escape to a quiet spot.
There are many types of pollutants, the countless other in the world.

Chapter II
A - Air pollution: air pollution contributed to the spread of many bacteria that cause diseases of people, including: influenza, the deadly epidemic diseases that spread quickly in the middle of the environment and disease, anthrax and plague, cholera, smallpox and fever, as well as incidences of human poisoning due to the effects of harmful compounds volatile arsenic as a result of microbial activity of some fungal species, as a major impact on the ozone layer and destroyed.
B - water pollution: the most important water pollution damages health, sanitation remnants of which have a number of pathogens such as certain bacterial species and fungal and viral diseases. The result of water pollution to the poisoning of marine organisms, and become part of the oil to eat small balls by fish, thus impacting directly on the food chain and cause water pollution, micro-organisms to the occurrence of many diseases such as typhoid fever, polio virus, as well as parasites.
C - radioactive contamination: the most important diseases to humans because of the emergence of radiation skin redness or blackening of the eye, atrophy also occurs in the cells of the bone marrow and collapsed in germ cells, also show some effects at a late stage of human life, such as leukemia and cancer of the thyroid White thyroid and lung cancer, leading to a decrease in white blood cells and intestinal infections and to reach beyond the risks to plants, fish, birds, leading to upset the ecological balance, and damage the food chain.

Introduction:
Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the physical systems or living organisms they are in.[1] Pollution can take the form of chemical substances, or energy, such as noise, heat, or light energy. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as point source or no point source
pollution.

Sometimes the term pollution is extended to include any
substance when it occurs at such unnaturally high concentration within a system that it endangers the stability of that system. For example, water is innocuous and essential for life, and yet at very high concentration, it could be considered a pollutant: if a person were to drink an excessive quantity of water, the physical system could be so overburdened that breakdown and even death could result. Another example is the potential of excessive noise to induce imbalance in a person's mental state, resulting in malfunction and psychosis .

Subject:
Humankind has had some effect upon the environment since the Paleolithic era during which the ability to generate fire was acquired. In the Iron Age, the use of tooling led to the practice of metal grinding on a small scale and resulted in minor accumulations of discarded material probably easily dispersed without too much impact. Human wastes would have polluted rivers or water sources to some degree. However, these effects could be expected predominantly to be dwarfed by the natural world.
Ancient cultures

The first advanced civilizations of Mesopotamia, Egypt, India, China, Persia, Greece and Rome increased the use of water for their manufacture of goods, increasingly forged metal and created fires of wood and peat for more elaborate purposes (for example, bathing, heating). Still, at this time the scale of higher activity did not disrupt ecosystems or greatly alter air or water quality.
Middle Ages

The European Dark Ages during the early Middle Ages were a great boon for the environment, in that industrial activity fell, and population levels did not grow rapidly. Toward the end of the Middle Ages populations grew and concentrated more within cities, creating pockets of readily evident contamination. In certain places air pollution levels were recognizable as health issues, and water pollution in population centers was a serious medium for disease transmission from untreated human waste.
Since travel and widespread information were less common, there did not exist a more general context than that of local consequences in which to consider pollution. Foul air would have been considered a nuissance and wood, or eventually, coal burning produced smoke, which in sufficient concentrations could be a health hazard in proximity to living quarters. Septic contamination or poisoning of a clean drinking water source was very easily fatal to those who depended on it, especially if such a resource was rare. Superstitions predominated and the extent of such concerns would probably have been little more than a sense of moderation and an avoidance of obvious extremes.
Official acknowledgement

But gradually increasing populations and the proliferation of basic industrial processes saw the emergence of a civilization that began to have a much greater collective impact on its surroundings. It was to be expected that the beginnings of environmental awareness would occur in the more developed cultures, particularly in the densest urban centers. The first medium warranting official policy measures in the emerging western world would be the most basic: the air we breathe.
The earliest known writings concerned with pollution were Arabic medical treatises written between the 9th and 13th centuries, by physicians such as al-Kindi (Alkindus), Qusta ibn Luqa (Costa ben Luca), Muhammad ibn Zakarīya Rāzi (Rhazes), Ibn Al-Jazzar, al-Tamimi, al-Masihi, Ibn Sina (Avicenna), Ali ibn Ridwan, Ibn Jumay, Isaac Israeli ben Solomon, Abd-el-latif, Ibn al-Quff, and Ibn al-Nafis. Their works covered a number of subjects related to pollution such as air contamination, water contamination, soil contamination, solid waste mishandling, and environmental assessments of certain localities.[2]
King Edward I of England banned the burning of sea-coal by proclamation in London in 1272, after its smoke had become a problem.[3][4] But the fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow. Air pollution would continue to be a problem there, especially later during the industrial revolution, and extending into the recent past with the Great Smog of 1952. This same city also recorded one of the earlier extreme cases of water quality problems with the Great Stink on the Thames of 1858, which led to construction of the London sewerage system soon afterward.
It was the industrial revolution that gave birth to environmental pollution as we know it today. The emergence of great factories and consumption of immense quantities of coal and other fossil fuels gave rise to unprecedented air pollution and the large volume of industrial chemical discharges added to the growing load of untreated human waste. Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in 1881. Other cities followed around the country until early in the 20th century, when the short lived Office of Air Pollution was created under the Department of the Interior. Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late 1940s, serving as another public reminder.[]
Modern awareness

Early Soviet poster, before the modern awareness: "The smoke of chimneys is the breath of Soviet Russia"
Pollution began to draw major public attention in the United States between the mid-1950s and early 1970s, when Congress passed the Noise Control Act, the Clean Air Act, the Clean Water Act and the National Environmental Policy Act.
Bad bouts of local pollution helped increase consciousness. PCB dumping in the Hudson River resulted in a ban by the EPA on consumption of its fish in 1974. Long-term dioxin contamination at Love Canal starting in 1947 became a national news story in 1978 and led to the Superfund legislation of 1980. Legal proceedings in the 1990s helped bring to light Chromium-6 releases in California--the champions of whose victims became famous. The pollution of industrial land gave rise to the name brownfield, a term now common in city planning. DDT was banned in most of the developed world after the publication of Rachel Carson's Silent Spring.
The development of nuclear science introduced radioactive contamination, which can remain lethally radioactive for hundreds of thousands of years. Lake Karachay, named by the Worldwatch Institute as the "most polluted spot" on earth, served as a disposal site for the Soviet Union thoroughout the 1950s and 1960s. Second place may go to the to the area of Chelyabinsk U.S.S.R. (see reference below) as the "Most polluted place on the planet".
Nuclear weapons continued to be tested in the Cold War, sometimes near inhabited areas, especially in the earlier stages of their development. The toll on the worst-affected populations and the growth since then in understanding about the critical threat to human health posed by radioactivity has also been a prohibitive complication associated with nuclear power. Though extreme care is practiced in that industry, the potential for disaster suggested by incidents such as those at Three Mile Island and Chernobyl pose a lingering specter of public mistrust. One legacy of nuclear testing before most forms were banned has been significantly raised levels of background radiation.
International catastrophes such as the wreck of the Amoco Cadiz oil tanker off the coast of Brittany in 1978 and the Bhopal disaster in 1984 have demonstrated the universality of such events and the scale on which efforts to address them needed to engage. The borderless nature of atmosphere and oceans inevitably resulted in the implication of pollution on a planetary level with the issue of global warming. Most recently the term persistent organic pollutant (POP) has come to describe a group of chemicals such as PBDEs and PFCs among others. Though their effects remain somewhat less well understood owing to a lack of experimental data, they have been detected in various ecological habitats far removed from industrial activity such as the Arctic, demonstrating diffusion and bioaccumulation after only a relatively brief period of widespread use.
Growing evidence of local and global pollution and an increasingly informed public over time have given rise to environmentalism and the environmental movement, which generally seek to limit human impact on the environment.
Pollution control

Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control.
