- Abstract
The Kola Peninsula (Figure 1) is the most industrially developed andurbanized region in the Russian North. The main pollution sources are the large smelters Severonickel and Pechenganickel, which are responsible for > 80 % of SO2 emission and nearly 100 % of the Ni and Cu emission in the region. The heterogeneous structure of the hydrologic network and geochemistry across the region cause natural variability in water chemistry. Due to moist and cool climate, large territories on the Kola are sensitive to acid precipitation, but around the smelters, geological peculiarities, erosion and alkaline dust emissions increase buffering capacity of waters to acidification. Lakeand river monitoring implemented from 1989-1993 by the laboratory ofwater ecosystems, Institute of Northern Ecology Problems was a basisfor GIS-analysis (ARC/VIEW-2.1) of the major constituents of water chemistry attributed to anthropogenic load in the region. After correction for sea salt, acid-neutralizing capacity (ANC) of waters was calculated. The highest concentrations of anthropogenic non-sea sulfateswere confined to the districts with high cation concentrations (Na+ + K+ + Ca2+ + Mg2+) that reduced negative effects. The most vulnerable regions were found in the northern tundra and high mountain tundra.
