Functional city zoning. Environmental assessment of eco-geological substance migration flows

One of the unsolved problems today is that of the division of the natural (geochemical background) and anthropogenic components of substance migration flows, such as complex integrated systems in the supergene zone. Not only qualitative, but also quantitative assessment of each component allows greater understanding of the correlation between the processes within the geological body and their impact on the environment. This study is based on academic knowledge in the field of geological sciences and study group research-developments aimed at the detailed examination of the migration of pollutants in anthropogenically modified city soils and the creation of a methodological framework in the field of the geochemical zoning of substance migration flows in the hypergenesis zone. We demonstrate that certain parameters of “zero-level” pollutant concentration for functional area land use can be developed for each city – the state of the environment before the beginning of a new stage of technogenesis. [Display omitted] •We divide the matter flows between the functional city zones.•We present the mathematical preparation of geochemical data.•The wide range of environmental analysis methods required for interpretation.•The interpretation of confidence level depends on the contrast in the geochemical data.•The net anthropogenic load evaluated for each functional city zone. This study is the first attempt to create a methodological approach to the separation of geochemical substance migration flows by analysing mathematical data matrices.
