The composition of the water and the health of people ... How strong is this relationship?

In world practice, water quality is judged on the basis of one hundred and biochemical parameters.Of course, it is impossible to constantly check the composition of water on each of these indicators, to ensure that it is fit for drinking purposes.

Do not think that our house is supplied with water, which is much dirtier than natural sources.After all, before entering the city water supply system, it goes through several stages of cleaning and preparation, as a result of which the composition of drinking water is brought to a state that meets the sanitary and epidemiological regulations.

The main problem is that the constantly increasing not only the volume but also the number of elements that pollute the water of lakes and rivers.Affect the condition of our water and the old water supply system, which even after a very good clean water again gets a certain amount of pollution.Therefore, the development of new water purification systems has received increasing attention and effort.

authorities monitor the biochemical composition of water, and constantly find ways to bring it to the desired sanepidnormami state.But it's not the only problem related to water quality.The chemical composition of the water in rivers and reservoirs, scientists were convinced that he was in different geographical latitudes different.The differences are quite extensive, because it all depends on the availability of minerals, salts and other soluble substances occurring in the earth's crust.In some places, the water contains an excess of minerals, and some do not even have their minimum set.

Thus, the composition of sea water - is a clear example of excessive salt content in the water, minerals, and waste products of the underwater world.Lakes formed by local glaciers melted, the water is very low in dissolved minerals, including calcium and magnesium salts.

People who consume water from such sources is formed in the body of useful trace elements deficiency, which affects the health.The negative consequences and causes increased salinity of the water, although the "hard water" easily lead to optimal chemical composition using conventional boiling and filtering.As for "soft water", she for a long time no one paid attention.

Therefore, residents of the Scandinavian countries, and the coast of Northern Urals Onega and Ladoga lakes lifetime consume water with low mineral content, even knowing that this composition of the water leads to the development of several diseases, including degenerative disc disease, hypertension, and rickets.For a long time, doctors and environmental services belong to the "soft" water is very favorable, considering that it gives less risk to health than heavily mineralized water.But it turned out that the inhabitants of these regions very quickly destroys tooth enamel, for women to identify more pathologies during pregnancy.There are other adverse health factors.

Currently, in many countries the chemical composition of water is becoming a major problem.The authorities understand that the quality of fresh water - that is the cornerstone of a healthy population and safe living environment.
