- Abstract
Sediment and water chemistry data were collected from ten lakes within a 110 km radius of Noril'sk in Siberia, the largest smelting complex in the world. Metals showing the most pronounced increase in enrichment near the smelters were Cu, Ni, Co, Ba and Zn. Cu and Ni appear to be as or more enriched in lake sediments around Noril'sk compared with levels previously reported for other locations. Although SO4 concentrations were highly elevated in the areas closest to the smelting complex, lake water pH remained elevated due to high concentrations of base cations in the waters. Sediment mercury enrichmentwas high in sediments near the smelting complex, but not more so than in other parts of the Arctic, suggesting that Hg either is not a major smelting product at Noril`sk, or that Hg is transported greater distances than other metals due to its longer atmospheric residence time.
