| Summary: | The article studies the impact of mercury-containing bottom sediments on the
pollution of the surface water body – the Elkhovka River, which for a long time was affected by the enterprises of the Kirovo-Chepetsk industrial hub, to assess the possibility of ensuring the standard water quality in the Elkhovka River.
Based on the data obtained as a result of determination of the mercury content in water samples, bottom sediments and measurements of the second-long water flow in the Elokhovka River along the watercourse length calculation of the mercury migration processes in the “water-bottom sediments” system has been carried out. It has been established that the decisive role in the formation of pollution belongs to migration processes in the system «water – bottom sediments», and the bottom sediments themselves have a dominant effect on the pollution of the Elkhovka River with mercury in concentrations exceeding MPC in fishery water. Migration of mercury from bottom sediments in the Elkhovka river riverbed in the coming years will not allow to ensure the standard water quality (MPC in fishery water) in the water body. A possible solution to this problem may be the laying of a new river channel with subsequent reclamation of the old channel. |
