RESULTS OF COMPREHENSIVE ECOLOGICAL STUDIES OF SEDIMENT SUBSTANCE BY GEOCHEMICAL AND MAGNETIC METHODS

The paper presents analytical research of distribution of technogenic and natural components of substance of land soils, Dnipro bottom sediments, air and water flows within Zaporizhzhia city. The research was jointly carried out by scientists of Institute of Geological sciences of NAS of Ukraine and Institute of Geology of Taras Shevchenko National University of Kyiv. Comprehensive monitoring of distribution of total iron content (X-ray fluorescence analysis, chemical methods) and its ferromagnetic component, linked to emissions of steel industry (magnetic methods), allowed us to examine impact of processing industry on environment components. Research results were indicative of persistent relationship between magnetic susceptibility and iron content in sediment substance of stable environments such as land soils and bottom sediments, where long-term processes of sediment accumulation level short-time situational changes. In air and water media short-time processes are more important.
