Results of the investigation of soil in the mouth part of the territory between the Angara and the Belaya rivers in the zone affected by the chemical plant in Usolye-Sibirskoe are presented. We present an estimation of the degree, scale and character of the areal distribution of mercury concentrations, as well as the concentrations of sulfate and chloride ions. Prevalence of the surface sink of mercury over the soil interflow is revealed. The main fields of anomalous concentrations of mercury and the anions are confined to the industrial zone of the chemical plant. A correlation of mercury with organic carbon and sulphate ion was discovered for the humus horizons of soils; a correlation of mercury with the oxides of iron and aluminium, manganese, titanium, and phosphorus of the mineral horizons of the studied soils was detected.
