Water and environmental problems are caused by the systematic inflow of unsaturated drainage waters and low-mineralized brines into the mine No 2 of the Stebnyk potash deposit. Filling the mine workings with unsaturated brines caused the risk of losi

The dating of young peatlands with 210Pb method is a difficult task. Standard 210Pb dating models require an exponential decrease in activity down the peat profile. In Arctic peatlands, we note a significant migratory capacity of lead, therefore, for
