Ecological-Geochemical Assessment Bottom Sediments of Tributaries of the Ural River under Conditions of Technogenic Influence

The spatial variability of the content of heavy metals in bottom sediments of the right tributaries of the river Ural is presented. Leading metals were identified in the geochemical associations of sediments of watercourses in areas of intense technogenic impact, associated with the specifics of existing industries. Data are presented for calculating the coefficient of average accumulation and the total indicator of soil pollution, which allows one to assess the level of pollution and the degree of sanitary and toxicological hazard of the rivers under study.
