GEOCHEMICAL CHARACTERISTICS OF SOILS: A CASE STUDY OF TERRITORY WITH A HIGH AEROTECHNOGENIC LOAD
The relevance of the research is caused by the fact that soil, being a connecting link between the Earth geospheres, plays an important role, both in the economic and social development of territories. Soils are of great ecological importance, going far beyond the agricultural framework, and at the...

The relevance of the research is caused by the fact that soil, being a connecting link between the Earth geospheres, plays an important role, both in the economic and social development of territories. Soils are of great ecological importance, going far beyond the agricultural framework, and at the same time are often influenced by technogenic factors that can lead to a change in the course of geochemical processes (as, for example, on the Kola Peninsula, where mining and metallurgical enterprises are concentrated). Therefore, the question arises about the difference in the geochemical characteristics of soils, including the fractional composition of chemical elements compounds, of technogenically transformed and background territories. The main aim of the research is assessment of the soils geochemical specificity, including the fractional composition of chemical elements compounds, of territory with a high aerotechnogenic load. Objects: soils of the territory with a high aerotechnogenic load (the catchment area of Lake Imandra, Kola Peninsula, Russia). Methods. The fractional composition of chemical elements compounds in soils was determined by successive selective extracts method. Chemical analysis of the extracts was determined by an inductively coupled plasma mass-spectrometric method. The mineralogical composition of the soils was studied by X-ray phase analysis and electron microscopy. Results. Studies show that most of the chemical elements remain bound in the residual fraction.
