The article represents the results of evaluation the chemical compounds in areas of unauthorized landfills of Ulan-Ude. Experiments was made with soil samples from four landfills which were taken because of location (near housing estates, industrial, transport and water objects) compounds and volume of waste and estimated age of the landfill. In article was made a quantitative assessment of the content in the soil of nickel, manganese, copper, zinc, cadmium and lead. All samples from landfills how exceeding heavy metals concentration from 1.08 to 15.84 times in contrast with background areas. Also we made soil structure valuation and the content of the main elements with scanning electron microscope. The results of analysis show the concentration of the main elements in the background samples and in samples from the landfill is not observed.

Keywords:unauthorized landfills, solid municipal waste, heavy metals.
