ABSTRACT. This study was conducted on the territory of the city of Sibay, Republic of Bashkortostan, where a large quarry is located, in which copper-zinc ore is extracted. The features of the distribution of mobile forms of heavy metals (Cu, Zn, Fe, Mn, Ni, Pb, Cd, Co) in soils and the content of bioelements in plant samples taken at sample sites adjacent to the quarry were studied. It was revealed that all soil samples had an increased content of essential (Si, Zn, Co), conditionally essential (Ni) and toxic (Cd) elements. According to the degree of contamination, the studied soils were classified as permissible and moderately dangerous. Elevated levels of Zn, Ni, Fe, Cd, and Co were found in the aboveground parts of the plant samples, and Cu, Zn, Ni, Fe, Mn, Cd, and Co were found in the roots.

KEYWORDS: heavy metals, total pollution indicator, accumulation index.
