What pollution
Pollution or environmental contamination is facing the most serious human disaster, a deterioration of environment pollution due to a defect in a component elements To lose their ability to perform its normal ..
and ground.
* Definition of pollution:
- What is the environmental pollution ? Certainly ask everyone to the same pollution, or what the definition.

* What the environment?

The definition is almost as simple to the mind of any one of us: "the fact that it is not clean," which subsequently caused damage and health problems and even human beings live, and the whole world, but if we look at the concept of pollution are more scientific and accurate:
"Is the change in the environment surrounding the organisms and human-induced his daily activities, which leads to the emergence of some resources that do not fit with the place where the organism and lead to Achtlalh."

Man is controlled mainly in making this a useful resource either pollutants or conversion of resources harmful to Think, for example, that:
We find that the biological animal waste as a resource useful if the use of fertilizers to agricultural soil, either, if disposed of in drains lead to the spread of diseases and epidemics.
Sharing the outputs of economic activity of the human person with a huge environmental pollution in operations that do not continue to be locked in place within the framework of jewelry or globally, because of pollutants moving through the layers of the atmosphere without regard to geographic boundaries or political level the globe.
water The manufacturing the other hand, plays a role not least on the role of products of economic activity in the transfer of a healthy environment to adverse environment and the emergence of a series of social and economic effects and changes in all aspects of the environment from air, soil and lakes, whether it near or far from sources of pollution
Of the reason behind the pollution of the environment?!
Rights is the main reason the fundamental cause of pollution in the environment and the emergence of all different kinds of pollutants and will represent as follows:
Rights = industrial expansion - technological advances - the misuse of resources - the population explosion.
- Man is invented.
- Is manufactured.
- Is used.
- A key component of the population.

* Pollution levels:
A - pollution risk:
Is spread over the surface of the globe in any place without him entirely, and could be called the unacceptable pollution that can live with a person without being subjected to harm or risk nor does it affect the balance in the environmental movement consensus among the elements of this balance.

B - pollution risk:
It shows the pollution has adverse effects affect the rights and the living environment and can be called the "pollution" critical, particularly in connection with industrial activity in all its forms. The danger lies in the need to take prompt preventive measures that protect rights and a real threat to his life can not be ignored, Man here is not allowed to live with this kind of pollution such as pollution from the former threat.

C - the devastating pollution:
Especially in the self-disposal of contaminants and natural processes at the air environment, Is pollution that occurs when the collapse of the environment and people together and eliminates all forms of environmental balance, that without destroying any chance of giving people - even to think of solutions - to intervene, and also find technological development related to human thought that creates a day of activities Radiological and nuclear weapons, the best example of the nuclear reactor accident, "Chernobyl" Needed reform to this pattern Allothei many years of reform and expenses are expensive, and they stop at this point, but generations of people affected in the long run it.


• * Types of pollution:
- Air pollution:
mean air pollution and the presence of harmful substances, causing damage to human health in the first place and then the environment in which we live and classification of air pollutants into two parts ...
- Waste pollution:

pollution of waste and environmental pollution, which include: litter - the radioactive waste ...
- Visual pollution: the
landscape is a distortion of the human eye when viewed feel uneasy myself, and we can also described as a sort of lack of artistic taste, or the disappearance of the aesthetic image of everything from buildings surrounding us ... To the roads ... Or ... piers

- Water pollution: includes water pollution of fresh water pollution first, second pollution of the marine environment ...

Noise pollution:
- noise pollution associated with noise or closely linked to urban areas and more advanced and special industrial parks to expand the use of machinery and means of modern technology ...
- The pollution of the soil soil is a source of the best fruits of the most elements that harm human use in this environment. It is not hard to realize how important it is the basic source of food for him and his family, and the resulting lack of awareness and understanding of this neglect

Have ...

- Food contamination: contamination of food increasing day after day even more alarming in developed countries with the highest levels of care and attention may be the result of one of the following reasons ..

* Pollution Damage:
1 - the emergence of various environmental problems, including population explosion.
2 - acid rain
3 - disruption of biological diversity) and the extinction of some aspects of plant and animal life.
4 - erosion of the ozone layer ..
5 - global warming.
6 - the phenomenon of desertification (desertification on the Fido) and the poverty of agricultural soils.
7 - The airspace of the airports of air pollution, leading to reduce the field of view horizontal and vertical winds greater ******* of dust and suspended particles and harmful gases.
8 - thermal coups and instability in climate, especially during the winter or during the night over the heavy concentration in the air, chromium and cadmium, lead and nickel.
9 - damaging effects, Valtrkizat high sulfur oxides and lead to erode the color effects over thousands of years so as to the ability of such oxide components to interact with those colors. The other hand, mixed under the influence of climatic conditions Baktarat de Rocيo turning to acid, which helps the erosion of calcium carbonate components of the statue of "Sphinx" in Egypt.
10 - a fire, through the self-ignition occurring Bmstahat sewage, especially in the summer heat a result of interactions Altkhmrat anaerobic shorthand and gases such as hydrogen sulfide and foul-smelling channel known as methane and other gases toxic flammable result of the contribution as the largest industrial operations in pollution.
11 - a growing proportion of oxides harmful heavy ****ls and airborne as it is by Fido on the pages of the site, especially lead, which contributes to the industry, ****l smelting, power generation plants

plastic, rubber and chemicals.
12 - not easy to purify sewage, and final disposal of effluents of factories.
13 - survival of industrial pollutants agricultural soil for a long period of time, and the difficulty of access to healthy food for man. Agricultural soils that contain grains of mud, which are properties of coherence and strength of gravity, making entry into force of water which is weak and therefore the possibility of the survival of industrial pollutants in the territories for a long period of time.
14 - reduced the amount of land cultivated to meet the industrial invasion, and thus change the parameters of population distribution and industrial facilities and the lack of fit between the occupied areas and areas inhabited by the population.
15 - Increased air humidity air to the large bodies of water to divert waste industry which constitutes a danger to the electricity networks and leads pedestrians and the threat of human beings.
16 - Increase heat flow coming from industrial areas (control temperature changes in human behavior Fido site) and carrying pollutants from various plankton and smoke and dust.

* Treatment of pollution:
1 - self-awareness that the person is a pollution disaster effort needed to be positive than it portends Pfnaih.
2 - licenses to stop industrial activity, which destroys the environment.
3 - displacement of the environment polluting industries away from the places of concentration of people plan a specific time, to stop agricultural land set-aside and not harm human health.
4 - Development of methods to combat air pollution, the solution does not lie in a further increase in the length of the chimney that does not prevent contamination but Erhalh to places beyond.
5 - To develop and disposal of garbage and waste, especially for those operations, which includes open-air burning that increase pollution.
6 - to carry out afforestation on a large scale for the disposal of air pollutants and absorption.
7 - Disclosure of the periodic cars, because the utility of one of the key factors causing pollution.
8 - the use of natural gas as sources of alternative energy sources, thermal power and who does not come out with large quantities of lead and sulfur.
9 - dealing with oil pollution, adding some chemical solvents that are oil deposition in the deep
, ocean or sea in case of leakage. As well as to develop strict rules for ships not to make any oil or chemical residues in the sea.
10 - the establishment of marine reserves and protected derived from the word natural protection imposed a ban on some areas that are included rare marine organisms, such endangered species or groups, which limited their presence in certain environments.
11 - resorting to the use of organic pesticides (organic pesticides are pesticides that do not contain chemical composition, but its components (the list of the environment) primarily as a natural garlic and onions .. and other natural materials other) and stay away from pesticides (insecticides site Fido) Different kinds of chemical herbicides, insects and fungi.

Pollution worldwide aggression, to have acquired the status as the world moves pollutants from the far north to the far south, it knows no boundaries and regional him. There are many countries that do not engage in industrial, mining, but suffered from pollution likewise. Variyah, clouds, water currents contribute to the transfer of pollutants from another country, for example: the pollution from burning oil wells of Kuwait, where scientists agreed that the effects of black smoke is not confined to the State of Kuwait, but it crossed the Black Sea and threatened Romania and Bulgaria.
