Abstract:	Our time is characterized by active struggle against various environmental pollutants. The soil factor is determinative and most informative for demonstration and detection of the dumps’ possible impact on the environment. We investigated the total copper, zinc, lead of the soil in landfills, as well as the corresponding metal contents in the plants growing there in Bereg County. Metal content of the contaminated soils Cu 47.9-34.8 mg/kg, Pb 67.18-43.7 mg/kg, Zn 237.5-228.2 mg/kg, and on the control: Cu 19.5 mg/kg, Pb 15.39 mg/kg, Zn 23.2 mg/kg. The contents of heavy metal in the plants growing within the landfill sites Cu 15.16-15.26 mg/kg, Pb 1.87-2.79 mg/kg, Zn 33,38-33,89 mg/kg and on the control: Cu 12,55 mg/kg, Pb 0.89 mg/kg, Zn 26,55 mg/kg. Numerous adventive plants (Urtica spp., Artemisia spp., Stenactis annua (L.) Nul, Polygonum sachalinense Fr. Schmidt, etc.) that force out autochthonous species are bioindicators of the polluted areas.
