Abstract

The article deals with the transformation of some physical and geochemical characteristics of soils ac-cording to significant man-made impact in Tiraspol. The classification of urban soils is proposed for different functional zones of the town. The simulation model of transformation of the physical characteristics (degree of compactness, porosity, mechanical structure, water permeability, water resistance) and soil pH made on the basis of this classification. The authors studied the problem of soil pollution by heavy metals in different technogenic zones of the town. The most dangerous soil pollutants in Tiraspol are lead, zinc, copper and cadmium. The concentrations of heavy metals are below the permissible level, however, in some areas the amount of lead in soil is approaching a critical value. The spatial distribution of heavy metals in soil is defined and the map of lead contamination in soils of Tiraspol is developed there.

Keywords

urban soils, physicochemical characteristics, heavy metals, concentration, soil samples, lead, man-made transformation, functional zone.
