Слайд 3The most part of water is not in open reservoirs,

and in earth crust: 110-190 million км³. These waters are

subdivided into two types:
♦ underground;
♦ a surface water.

WATER POLLUTION

Слайд 5Water pollution is the contamination of water bodies (e.g. lakes,

rivers, oceans and groundwater). Water pollution occurs when pollutants are

discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.

Fish and reptiles can’t live in them. All the birds leave their habitats and many plants die.

The polluted water ruins more people, than war and all other forms

POLLUTION SOURCES

♦ The largest potential source of pollution — factories and

plants.
♦ Harmful substances get to the rivers and lakes with

rain waters flowing from territories of cities and fields.
♦ Fast pollution of underground waters round cities.
♦ Forestry and open drainage — sources of a considerable quantity of the substances getting to fresh water, first of all iron, aluminum and cadmium

Слайд 8MEDITERRANEAN SEA THE DIRTIEST IN THE WORLD
Waters of the Mediterranean

are polluted, especially in areas of large seaports, oil products

and other waste, - it becomes hazardous for health.
In each cubic meter of the Mediterranean water 33 kinds of a various waste contain, and on each liter 10 grams of oil products are necessary.

Слайд 11In 1966 a pulp-and-paper factory was built on the shore

of Lake Baikal. After decades of protest, the plant was

closed in November 2008. However, on 4 January 2010 the production was resumed. On 13 January 2010 Vladimir Putin introduced changes in the legislation legalising the operation of the mill. This was based on Putin's visual verification from a mini-submarine "I could see with my own eyes — and scientists can confirm — Baikal is in good condition and there is practically no pollution".

Слайд 13Transformation into “blossoming oases” deserts of Kazakhstan, Uzbekistan and Turkmen

has ended with catastrophic reduction of the area of Aral

Sea. The branched out network of irrigation canals has disturbed balance between inflow of water and its evaporation, having transformed coast Aral in the cemetery of the ships.
