The Involvement of Heavy Metals in the Main Trophic Chains in Agrophytocenoses of the Sterlitamak Region of the Republic of Bashkortostan

The work was aimed at evaluating the involvement of heavy metals in the biogeochemical cycle in the soil-plant system in the setting of agrophytocenoses. The elemental composition of soil and plants was determined by atomic absorption. The sanitary-hygienic and ecological assessment of the condition of soils and plants in the region by heavy metals content has been provided for the first time; for individual items, the health risk of soil contamination and used agricultural products has been assessed.For the first time, background concentrations of priority pollutants in the soil and plants have been found at different sites from contamination sources; the annual average volumes of removal of Cd, Pb, Zn, Cu, Ni, Cr, and Mn from the soil have been established; the antagonistic-synergistic interactions have been revealed at the introduction of macro- and microelements into plants.
