Indicators of the absolute content and mobility of heavy metals (Cd, Pb, Co, Cu, Ni, Zn, Cr, Mn) and Fe in the soils and sediments of the basin of the Nizhnekamsk reservoir within the Republic of Tatarstan have been established. The concentrations of acid-soluble and mobile forms of metals were mainly within the regional geochemical background. In rivers sediments an increase in the mobility of copper, manganese and iron is noted, which is reflected in an increase in the content of their dissolved forms in water to values, that exceed the permissible concentrations. The intensity of water migration of metals in the basin of the Nizhnekamsk reservoir is assessed as В«strongВ» for Cd and Co, В«mediumВ» - for Cu, Ni, Zn, Cr and В«weakВ» - for Pb, Mn, Fe.

Key words: heavy metals, geochemical background, pollution, mobility, soils, bottom sediments, surface waters, intensity of water migration, Nizhnekamskoe reservoir
