Abstract: The article examines the features of the accumulation and distribution of microelements in angustifolia fireweed plants growing on the territory of a conserved copper pyrite deposit to substantiate the possibility of its use in a set of measures aimed at localizing the migration of heavy metals in soils and technogenic soils when designing mining systems. The relevance is determined by the need to develop and implement measures to form biogeochemical barriers in order to improve the organization of production processes during the development of mineral deposits, taking into account environmental safety. The research methods consist of analyzing the state of land, water, and biological plant resources at the sites where overburden and host rocks are placed at the stage of conservation of the copper pyrite deposit. As a result of the studies, it was found that all studied plant samples are characterized by a barrier type of accumulation of microelements, with the exception of the element Fe. Analysis of the content of copper, zinc and iron in the roots of angustifolia willowherb shows an excess of the concentration of these elements compared to the background site. 5.6 times, 7.7 times, 2.1 times, respectively. It is noted that an excess of the concentration of chemical elements is also observed in the above-ground parts of plants: 5.3 times for copper, 3.8 times for zinc and 2 times for iron. These results indicate the need to take into account the KKB and CN when developing methods for designing measures that localize the migration of heavy metals in soils and technogenic soils by forming biogeochemical barriers and can be useful to designers and subsoil users when developing a section of project documentation for environmental protection, including at the stage of reclamation of disturbed lands.
