Pollution

What is pollution?

Is to change the physical or chemical or biological distinctive lead to a

detrimental effect on air, water or land or harm to human health and

other living organisms, as well as lead to

damage to the production process as a result

of the impact on the state of renewable resources.

Is to destroy or distort the natural purity of living by external factors transmitted by air, water or soil.

Pollution phenomenon of environmental phenomena that took much of the attention of the governments of the world since the second half of the twentieth century. The problem of pollution one of the most important environmental problems pressing began to take dimensions of environmental, economic and social problems, especially after the industrial revolution in Europe and industrial expansion tremendous powered by modern technology, and took industries in recent trends in serious represented in the great diversity and the emergence of some industries complex and accompanied in many often serious pollution usually leads to the deterioration of the biosphere and the elimination of the organization of the global environment.

Types of pollution:*Air pollution

*Soil pollution

*Waste pollution

*Water pollution and the marine environment

*Noise pollution

*Visual pollution

Air pollution:Air pollution is atmospheric exposure to chemicals or particles, physical or biological compounds cause damage and harm to humans and other organisms, or lead to damage to the natural environment.The atmosphere is a system of interacting natural gas complex and which are necessary to support life on the planet. Has long been regarded as the depletion of the ozone layer in the stratosphere due to air pollution of the most dangerous things that represent a significant threat to human life and ecosystems on the planet.

Soil is defined as the surface layer of the earth, was formed through a series of complex processes over millions of years.And soil pollution means entry of foreign matter in the soil or an increase in the concentration of one of the components of natural, which leads to a change in the chemical composition and physical soil, these substances called pollutants soil may be pesticides or chemical fertilizers or acid rain or waste (industrial - Appliances - radioactive etc.)The soil contaminated by its proximity to the substance or substances in quantities or concentrations unusually either increase or decrease causing risk to human health, animal and plant or plant engineering at the expense of agricultural land or surface water and groundwater and is considered one of the most prominent problems of the environment and the most complex and the most difficult solution.And soil pollution leads to contamination of agricultural crops, which leads to damage to human health that feeds directly, and through the transfer of contaminants to animal products such as milk, eggs and meat.The many sources of soil pollution of the atmosphere, hydrosphere, biosphere, including the rights and activities

Soil pollution:

Waste pollution:Waste pollution rights or environment are industrial waste, especially if were not dealt with before delivered by outside factories When the dumping of waste adjacent to the plant motionless the wind carry the gases emerging from and perhaps parts of them to distant places and these gases What is nontoxic and can affect human health.

Noise pollution:For example:Rail noise: a problem that haunted living near the rail or train stations, where high gnashing of train wheels on the rails, but the problem is less complicated compared to the noise of cars for the residents.

Aircraft noise: This problem appears for people living near airports in general. The jets are becoming far less troublesome because

of advances in the aircraft industry.

Visual pollution:Visual pollution is the term given to unattractive visual elements, a landscape, or anything else a person wants to be seen.And examples of bad boards, garbage, and some of the walls, and buildings is studied, unregulated and architecture, labels and herbs and random ads.Or in other words, is to distort any stock fall by the human eye feels when you consider him uneasy myself. We also described as a kind of lack of artistic taste, or the disappearance of the image aesthetic for everything from buildings around us ... To the streets ... Or sidewalks ... And others.

Water pollution and the marine environment:

Water pollution is any change in physical or chemical in water quality, either directly or indirectly, adversely affect the organisms,

or makes the water unfit for use required, and the impact of water pollution

a significant impact in the lives of individual, family and society, water is the

requirement is vital to humans and other organisms the water may be a major reason for the termination of life on Earth if it is

contaminated.The water pollution is divided into two main types, the first is the

natural pollution, and appears in the change in water temperature or salinity increase, or increase

in suspended solids. The other type is the chemical pollution, and multiple forms such as

pollution by sewage, oil spill and agricultural waste pollution.

We can handle altot through the development of lawsthat determine the rate of air pollutants through the cooperation

of the competent authorities with the members of the community as a whole and to identify specific areas for the

spread of the factories away from the centers of human and purification of drinking

water and domestic use and to prevent factories

from dumping waste into rivers and lakes, but after being treated well

and treatment garbage in order to preserve the soil and water pollution. awareness that the role of human

environment and pay to keep them out of the main

factors that contribute to the preservation of the environment
