The current state of peat deposits in bog ecosystems within the emission plume from Norilsk industrial area was investigated. On the basis of a visual survey and analysis of physical, chemical and geochemical properties of the peat it was determined that the bogs in the four key areas, located further than 80 km from the source of emissions, had been only slightly exposed to anthropogenic influences. The bogs, located at a distance of 45 km from Norilsk had received severe technogenic impact.
