Abstract

The contents of chemical elements in soils and plants collected from the tundra ecosystems of Western Taimyr (Russia) have been studied to determine the natural factors affecting the concentrations of chemical elements in plants and soils. Naturally high contents of Be, Cu, Mn, Nb, Ni, Pb, Sr, V, and Zn have been found in the soils, most likely due to polymetallic ore deposits in the region. The increased accumulation of Fe, Mn, Ni, Pb, and Cd by plants has also been observed, which could be attributed to low soil pH and excessive soil moistening.
