metadata.name: dc.description.abstract
metadata.value: The article presents the results of studies of the hydrochemical composition of five urban lakes
  of Murmansk. It was found that the chemical composition of the water of the studied urban
  lakes is significantly different from the composition of the lakes of the northeastern part of
  the Murmansk region of the Barents Sea catchment, which was taken as the background. The
  water pH values have increased in comparison with the background values, as well as mineralization,
  the content of major ions, nutrients, and heavy metals. An increase in the content
  of the main cations of alkaline and alkaline-earth metals (Ca2+, Mg2+, Na+ и K+), as well as the main anions (HCO3
  –, SO4
  2–, Cl–), is associated with the influence of urban environments,
  including the use of reagents for deicing of roads. Due to the influx of marine aerosols in the
  waters of urban lakes, the content of other alkaline (Li and Rb) and alkaline-earth (Sr and Ba)
  metals, as well as B and Br, is increased. Mineralization of water in the Murmansk lakes is ten
  times higher than the values recorded in the lakes of the northeastern part of the Murmansk
  region of the Barents Sea catchment. In the water of urban lakes, the content of compounds of
  the nitrogen group, especially the ammonium ion, is significantly increased, which indicates
  the formation of a restorative environment that has a detrimental effect on hydrobionts. Lakes
  Ledovoe and Yuzhnoe are the most polluted among the studied lakes, characterized by the
  highest content of the above-mentioned indicators, as well as many heavy metals (Ni, Cu, Zn,
  Co, As, Mo and W). At the same time, there is a decrease in the content of organic substances
  in the most polluted lakes due to inhibition of biological processes.
