Deterioration of ecological-hygienic characteristics of water and bottom sediments of the small rivers in Samara oblast and increase of risk for the population health

Studying the ecological-hygienic characteristics of water and bottom sediments of the small rivers in Samara oblast is actual. On example of experimental animals (white rats) ability of toxic substances, containing in water and bottom sediments of the small rivers, to get through the intact skin, causing destructive changes of internal organs has been defined. Thereby threat of pathological influence on live organisms by polluted water and extracts of bottom sediments has been confirmed. Deterioration of ecological-hygienic situation at rivers Krivusha, Chapaevka, Kondurcha, Sok is confirmed. The adverse ecological situation of the small rivers assumes the further deterioration of their ecological-hygienic condition that increases risk for the population health and amateur fishery.
