Karazin popup.description2 The object of the study are geochemical processes that underlie the formation and development of geochemical barriers in specific landscapes. Purpose: To develop methodological principles of obtaining timely information about the processes of development and formation of abnormal concentrations of toxic elements in areas involving representation of geochemical barriers. Method: X-ray fluorescence and X-ray chemical analysis of elemental composition of the soil cover to quantify the dynamic characteristics of man-made barriers on the basis of the measurement of different forms of the existence of heavy toxic metals. Considered natural and man-made factors and forms of migration of heavy toxic metals in the environment in technogenesis, the effect of heavy metals in soil and vegetation and their toxic effects on living organisms. Considered the development of different types of man-made geochemical barriers. The possibility of using artificial (engineered) and natural geochemical barriers to protect the environment from the spread of contaminants. Based on a review of the method XRF analysis capabilities for today's eco-geochemical investigations of the expediency of this method for quantifying geochemical barriers on their stage of development and formation. Field monitoring studies the territory of several sites and found a geochemical barrier, quantities of which (the gradient and contrast) were identified. A generalization of the results and provides recommendations for the use of research results. Product Description popup.authors Григор'єв О. Малахов О. Нечепоренко А. Полевич О. Удалов І.
