It will take 2-3 years to restore the ecosystem of the poisoned River Seim
Scientists say that it may take 2-3 years to restore the ecosystems of the Seim and Desna rivers, despite the fact that the situation is under control.
The quality of water in the River Seim, poisoned by the Russians, is gradually improving, and the movement of pollution in Desna is slowing down, the Ministry of Environment reported.
In particular, the content of dissolved oxygen in the Seim, in places of pollution, reached the norm — 4 mg per cubic decimeter. Plague of fish is not recorded.
Pollution has slowed down in Desna, and state and local authorities are currently trying to contain and eliminate the effects of the pollution. Three aeration plants are operating in Chernihiv Region, and additional aeration systems are also being installed in Kyiv Region.
15 boats and 142 specialists were involved in the collection of dead fish in the Chernihiv region. So far, it has been possible to collect 31 tons of dead fish in Sumy Region and Chernihiv Region.
In addition, the State Water Agency and the State Ecoinspection continue to carry out intensified crisis monitoring of the state of water. 195 water samples have already been taken in Chernihiv, Sumy and Kyiv regions.
According to Volodymyr Osadchyi, director of Ukrainian Hydrometeorological Istitute of and NAS of Ukraine, with the help of satellite images, it was possible to estimate the amount of polluted water that entered the River Seim from a sugar factory in the Kursk region — about 5,600 tons.
Despite the positive dynamics of water purification, the Seimu and Desna ecosystems can recover in 2-3 years.
Currently, the Ministry of Environment, together with scientists, representatives of the State Water Agency and involved bodies, are working on creating a single, most optimal approach to restoring ecosystems and the natural quality of water in rivers.
It will be recalled that, starting from August 14, the Russians caused large-scale pollution of the River Seim. As a result of pollution, fish died en masse. The pollution immediately spread throughout the water area of the Seim River within the Sumy Region and reached Chernihiv Region.
