Three-dimensional distribution of heavy metals in the areas of tailing pits of the Kryvyi Rih mining and processing objects

the largest impact on pollution of the environment in Kryvyi Rih. As the objects of research, soils from ravines and tailing pits located close
to mining and processing objects were taken. Specification of geochemical concentrations of heavy metals was done by atomic emission
spectral analysis and atomic absorption spectral analysis. The results were correlated with the maximum allowable concentrations
established by the normative documents. The results of the performed studies have confirmed that the accumulation of heavy metals in the
geologic environment is affected by mining and processing plants, as well as by domestic waste and municipal wastewater. As an additional
factor of the distribution of heavy metals in soils, prevailing winds and ground relief have been taken into account. Also, the trend to active
absorption of some part of heavy metals by vegetation has been confirmed. In combination with periodic recultivation works, it significantly
reduces concentrations of heavy metals to the levels not exceeding the maximum allowable concentrations.
