Abstract: The amount of lands subject to contamination with heavy metal ions is increasing due to mining of minerals. Therefore, research on the use of various composite sorbents / ameliorants, which in combination with perennial plants can act as a biogeochemical barrier to the spread of heavy metal ions in the environment, is currently relevant. In the “soil–and-plant” system, use of the peat-and-diatomite ameliorant granulated on site in the direction of the man-made flow showed a high degree of survival of the awnless brome grass (Brōmus inērmis) compared with zero survival on the reference area. The dynamics of heavy metal accumulation in the plant biomass shows an increase in the content of copper and zinc, in comparison with the background values during the second year of research, while during the third year there is a decrease in the content of copper in the biomass from 235 to 40 mg / kg, with an increase in zinc content from 473 mg / kg to 510 mg / kg. The data obtained confirm the limits of metal fluctuations in the plant biomass established by previous researchers. At the peat-and-diatomite ameliorant sites, an increase in the concentration of Cu2+ and Zn2+ was also observed in comparison with the other survey locations, which indicates the possibility of using granular peat-and-diatomite ameliorant as a material to create a network of biogeochemical barriers perpendicular to the direction of the man-made flow.
