Specifics of strontium accumulation in the floodplain soils of the Kuda River, Irkutsk Region

Abstract

Data on strontium accumulation acquired by studying the floodplain soils of the Kuda River, Irkutsk Region, show that the bulk accumulation of this element and the accumulation of its water-soluble species are controlled by evaporative concentration. Floodplain areas maximally enriched in water-soluble strontium are defined. These areas are the most potentially hazardous if involved in agricultural activities because Sr can be transferred there into the surface- and soil–groundwaters in concentrations several times higher than the maximum permissible concentrations of this element in water bodies.
