metadata.value: The purpose of the work is to establish the basic laws of the formation of the hydrochemical background for the development of standards of permissible impact on raised bogs.
  Research methods included physical and chemical analysis, water balance calculations and
  statistical processing of analytical data. The hydrochemical background of raised bogs was
  established based on materials of generalization of hydrochemical data of the typical and
  most studied bogs of the Leningrad (Lammin-Suo swamp), Arkhangelsk (Ilasskoe swamp)
  and Tomsk (Vasyugan swamp) Oblasts. The spatial and seasonal variability of the main ingredients of chemical composition (main ions, biogenic elements, organic matter and heavy
  metals) of marsh waters was investigated. The hydrochemical background was calculated
  using the combined samples’ mean annual values of concentrations of all investigated raised
  bogs. It is acceptable in view of the absence of statistically significant differences between
  intra-annual hydrochemical indicators of oligotrophic microlandscapes of raised bogs. For
  the purpose of preserving the oligotrophic nutrient status of raised bogs, maximum permissible concentrations (MPC) of chemicals in discharged sewage were developed. On the
  basis of water-balance calculations, a simplified definition of the permissible mass of the
  introduction of chemicals from sewage discharge was performed. Significant differences
  were revealed in the values of the standards of permissible impact (SPI) using the generally accepted maximum permissible concentrations (MPC) and the approximately allowable
  concentration (AAC) developed by the authors. The SPI calculated by the AAC for the main
  ions, total mineralization and nitrates was 5 times lower; and for organic substances, ammonium and total iron — 5–50 times more than calculated by LPC. Thus, the use of more
  flexible criteria for the concentrations of discharged pollutants makes it possible to both
  minimize the degree of anthropogenic disturbances of raised bogs, and significantly reduce
  the cost of wastewater treatment from a number of chemical substances of the bogs’ natural
  background.
