Аннотация: Nonferrousmetal smelting operations are a recognized source of metal accumulation in surroundingsoils. In Mednogorsk, Russia, soil contamination results from atmospheric emissions from alocal copper (Cu) smelter. This study aimed to assess health risks by analyzing the levels ofCu,As,Cd,Pb,Zn in 20 Mednogorsk topsoil samplesand three background area samples. The phytotoxicity of metals to Lolium perenne was alsoevaluated. Phytotoxicity tests were performed on ryegrass using a standard protocol. The levels of Cu correlated with those of other elements, indicating that the smelterwas the source. These risklevels are unacceptable and require specific intervention by the relevant authorities. However,only 20% of the samples showed high phytotoxicity, mostly in acidic soils (pH<4.0). Thisdiscussion focuses on the potential of soil phytostabilization to reduce human metal exposure,as the results provide valuable insights for managing metal pollution in regions affected bynonferrous smelter emissions worldwide.
