Heavy metal concentrations in plants and technozems of the reclaimed areas of the Dzhida tungstenmolybdenum industrial complex have been established. The level of total pollution of technozems by heavy metals (As, Cd, Cu, Mn, Pb, Sb, Zn, Ni, V), as compared to the existing MACs (APC), varied from permissible to moderately dangerous. The content of 15 elements (As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, Sb, V, W, Zn, Ва, Sr), as compared to the background, varied from permissible to extremely dangerous. In most cases, the concentration of HM in plants exceeded its average content in the vegetation of the continents. The content of Cd, Co, Cr, Pb in plants has been shown to exceed the maximum permissible concentrations in feed. The reclamation activities had a positive effect.
