What's pouring on our heads, the quality of rainwater

    



.

Gift of the Gods rainwater believed the people in the drylands. Rainwater was very useful, rejuvenated and softened human skin, was considered an "elixir of youth".

If we consider snow as a rain of snowflakes, rain (snow) water which is collected in Greenland or in the mountains, the clean and useful and sell this water very expensive.

Pure water from heaven is currently not very safe and have almost lost the properties of drinking water in Metropolitan areas and industrial cities.

The Ministry of health said that a rain drop weighs about 50 ml and when it falls from the clouds, washes out more than 16 litres of air and absorbs the various impurities contained therein.

The quality of rain water depends on the contamination of the territory over which the formed rain clouds. Rainwater can contain a variety of chemical compounds, metals, emitted into the atmosphere smoke, steam and exhaust gases.





Acid rain formed from chemical reactions of sulfur and nitrogen with water. Environmentalists believe that rainwater is almost not suitable for human use, and all the rain can be called "acid". More than 100 years ago, English chemist A. Smith opened the dependence of acid rain from atmospheric pollution, confirmed now.

Besides sulfur and nitrogen in rain water, the possible presence of ammonia, surfactants — surfactants, which are used in the production of washing powders and detergents, heavy metals. All these contaminants are formed from the emissions in the atmosphere and in water bodies of various wastes and products of incomplete combustion with the smoke that cause harm to humans and the environment.



In some regions and cities, environmentalists and just curious people periodically take samples of rain water and conduct chemical analyses. In Kiev made the analysis of rainwater in one of the chemical laboratories of the city, and it turned out that "acid rain" in Kiev is not coming, its composition meets the standards of pure water.

Valid acidity of rainwater in Kiev so that you can use the water even for rinsing hair. The environmental situation on Earth is that"acid rain" killed entire living nature. In Switzerland, in Australia, Germany and many other countries have experienced rain with the acidity of the water pH from 6 to 5.5 and had deteriorated the environment.



At this acid rain water killed trees, dying fauna in water bodies and sick people. Environmentalists insist that the need to reduce emissions and do not pollute natural water bodies to revive the quality of rainwater and use it for saving drinking water from natural sources.

Despite the different quality of rainwater in different countries, cities and regions, rainwater is collected and used for watering areas, wash areas and yards for domestic use. Rain water passed through a filter and is collected in storage tanks and then pump serves in the required space usage.
