Slits from a small lake in Karelia may be beneficial to people
Scientific Project LomonosovRussian limnologists have investigated the chemical composition of a small reservoir in the north-western part of Russia and have found out that sediment cores (slits) meet the standards of heavy metals concentrations. The scientist have established that the lake is clean despite the close proximity of a railway and a village. Theoretically, the lake’s sediment cores may be used in agricultural work or medicine.
