Ural district is the undisputed leader of Russia on air pollution emissions from stationary sources: they constitute more than 20% of the total number of air pollutants.

Ecology of the Urals poison and accumulated 20 billion. tons of industrial waste. In a specified amount and waste treatment plants and stripping, and enclosing rocks. Thousands of hectares of land are reserved for test sites and landfills for storage of industrial waste. And quite an impressive part of this waste is a serious threat to the ecology of the Urals.

The level of heavy metals in soils in the vicinity of the enterprises of ferrous and non-ferrous metallurgy, tens or hundreds of times above permissible standards. Due to mine workings seriously violated land, have changed the natural landscape of the Urals. As a result of long-term iron ore mining activities from the face of the Earth were totally cleared Mountain High and Magnetic. Almost fully developed Chelyabinsk coal basin: he turned into a career, pits and refuse heaps. A serious problem of ecology in the Urals is the fact that a considerable number of disturbed lands is located practically in the urban centres-on site waste mineral deposits. For example, in Nizhny Tagil such lands make up 30% of the whole territory.

Reservoirs close to extractive industries and black and nonferrous metallurgy heavily polluted heavy metal. In addition, surface water in the Urals actively Situation of water pollution in the Urals is compounding the fact that 40% of urban and 95% of the rural population of the Ural district do not have running water and sewers. As a result, about 80% of the rivers Ural found to be unusable in the system water polluted with oil products.

One of the most important environmental problems in the Urals is the radiation situation at the site of the opening of the first Russian plutonium-producing complex at Mayak in the cities of Ozersk, Kyshtym, Chelyabinsk region and adjacent areas. After the explosion, containers with radioactive waste in the year 1957, formed the East-Ural radioactive trace, which is a 2000 square kilometers of contaminated territories. More than 500 000 inhabitants of the Chelyabinsk region were subjected to elevated exposure to radiation. Now here are representing potential threats to sources of pollution: Karachay (Lake that holds liquid radioactive waste) landfills of solid industrial waste, Cascade ponds with radioactive solutions. Data sources pose a real threat of radionuclide contamination of the Ob River basin and the Arctic Ocean. Techa river received a serious degree of radiation contamination due to waste on "Lighthouse" and was removed from the water.

A serious danger to the ecology of the Kurgan region and Udmurtia is stored chemical weapons here, of whom are potent poisons. The threat is intensifying with each passing day, as over time the process of corrosion of exposed metal tanks and munitions containing toxic substances, due to the risk of leakage of toxic substances is increasing.

You must create public natural reserves and wildlife sanctuaries, national parks and natural monuments, rivers of water (Lakes, reservoirs), green areas, as well as beach and recreational area. Need to investigate environmental issues not only of the southern Urals, but throughout our planet as a whole, and to explore new ways of addressing them (more acceptable in a particular area of land, part of the globe).
