The main river of Russia is Volga dies – it actually turned into a “big dump”.
The situation with water is a slow-moving ecological disaster, writes with reference to .
According to the acting Director of the Institute of ecology of Volga basin of RAS, Professor, doctor of biological Sciences Sergey Saksonov, in Russia few people are aware of the scale of the disaster.
According to him, the impact on the Volga now how big and deep that the river is simply not time to self-clean. This leads to the silting up of the bottom. In the result, organic matter deposited in the sediments, which to a certain point absorb them like a sponge, forming a kind of reservoir of all incoming Volga sewage.
“We recently assessed the damage, which is constantly applied to the biological resources of the Volga. According to conservative estimates, we get the sum of 70 million rubles annually,” – said the scientist.
Saxon stressed that the river disappears in a natural biomass and appear alien to her body.
“Blue-green algae, which under special conditions of reproduction give an enormous biomass and lead to algal blooms. In addition, they aggressively absorb the oxygen, displacing the Volga and other living organisms. That’s where the real trouble – the organic pollution of the Volga is now just tremendous,” – said the expert.
He underlined that the Volga is, in fact, has become a system of reservoirs, or, in other words, the “cascade waterworks with stagnant regime.” At the same time just to pull the contaminated reservoir is impossible.
“Imagine that the Kuibyshev reservoir later. Millions of square hectares of its muddy bottom turn into a poisonous dust that the wind blows in all directions. And then we get a new Chernobyl! Our recent study of the Kuibyshev reservoir show that it sediments as filled with these harmful substances and has now begun a process of secondary pollution of the Volga water — only already from its bottom. Do not be surprised if a similar situation exists in other parts of the Volga-Kama cascade of HPPs in Armenia,” he explained.
“On the Volga there were only small fragments rifiling sites located generally behind the reservoir dams. For example, natural flow is preserved on a small stretch from Zhigulevsk to Samara, where the water of the river living organisms. Alas, but as a natural pond and the river we lost the Volga,” – said Saxon.
