The spatial variability of the content of heavy metals in the surface waters of the right tributaries of the river is presented Ural. The data of the calculation of the index of water pollution are presented, which make it possible to assess the water quality of the studied rivers by categories of pollution. The results of biotesting of water pollution using the seeds of cress Lepidium sativum L. and radish Raphanus sativus as a test objects are discussed.

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.
