Transformation of composition of heavy metals in environmental components in the urbanized area's of Ukraine

ABSTRACT

 

Report on the research project: 289 p., 6 chapters, 64 tables, 38 figures, 197 references.

 

The object of the research: agglomerations of the cities of Kyiv, Zaporizhzhia, Molochansk, suburban areas (the city of Brovary), industrial agglomerations of Donbas (Luhansk industrial agglomeration, Severodonetsk-Lysychansk industrial agglomeration, Dzerzhynsk-Horlivsk-Yenakiivsk industrial agglomeration), groundwaters and bottom sediments of the Dnipro basin rivers and open water areas in the city of Kyiv, surface and mine waters of Donbas.

The purpose of the research is to investigate the heavy metal compounds (HM) transformation in bio-inert systems (soil, natural waters, vegetation) of urban areas of Ukraine.

Research methods: general chemical analysis, granulometric, potentiometric, atomic absorption, inductively coupled plasma mass spectrometry, mathematical, statistical, and cartographic methods.

Geochemical approaches to determine the transformation of heavy metal compounds in the environment components of urban areas, taking into account landscape and geochemical conditions and man-made geochemical anomalies are stated. For research territories cartographic schemes of heavy metal compounds transformation in environmental components have been constructed.

The forms of heavy metals finding in soils and bottom sediments by the method of sequential dissolution have been revealed. It is established that the series of intensity of heavy metals pollution in most cases do not coincide with the series of their mobility, which depends on the properties of the elements and physicochemical characteristics of soils. With the increase in total soil pollution, there is an increase in the mobility of heavy metals, and hence their availability to plants. Migration forms of microelements in groundwater have been studied using the method of thermodynamic modeling in order to establish patterns of changes in chemical composition and conditions of existence of successive equilibrium states. Biogeochemical parameters of soils characteristic of technogenic geochemical anomalies formed under the influence of urbanization processes are calculated.

Measures were proposed to ensure the environmental safety of urban areas by component determination of the content of heavy metal compounds in the studied landfills and scientific substantiation of the system of measures to restore critical infrastructure, including water supply and industrial wastewater treatment.

The results of the study can be used by economic entities, management and environmental organizations in the environmental assessment of environmental components of urban areas of Ukraine.
