The article presents the results of the ecological assessment of the content of heavy metals in soil and plants in the zone of influence of the landfill for solid municipal waste of Ulan-Ude. The study was carried out with samples of soil and Artemisia scoparia, taken in 20 points on the border of the landfill site in and sanitary protection zone. Bulk concentrations of Cu, Zn, Pb were within the limits of maximum permissible concentrations and their background values were exceeded 1.1 to 23.25 times. Comparison of concentrations of heavy metals in soil and plants showed that the concentration of heavy metals in plants was many times higher than in soil: for Cu from 12.3 to 15.79 times, for Zn from 16.3 to 141.7 times.
