Abstract

Differentiation of the elements and formation of lithochemical and hydrochemical heterogeneities occur in the Irkutsk Reservoir. Lithochemical heterogeneities are represented by two fields: with the predominated elements of lithophile-chalcophile association or lithophile-siderophile association. The bottom sediments have a pollution degree from permissible to moderately hazardous. Hydrochemical field is characterized by lithophile and chalcophile association of the elements. The elemental composition of the water corresponds to quality standards of the unpolluted water.
