Assessment of Soil Phytotoxicity under the Conditions of Technogenic Impact of Enterprises of the Mining and Metallurgical Complex of the Republic of Bashkortostan

The soil contamination with heavy metals (HM) Cu, Zn, Fe, Mn, Cd and Pb was studied in the zone of influence of the Beloretsk Metallurgical Plant and the Sibay Beneficiating Plant (Republic of Bashkortostan). The direct dependence of phytotoxicity of soils on the content of HM in it at their relatively high concentrations has been established.
