Abstract:
This paper presents the contemporary landscapes and their geoecological condition in one of the most technogenic areas in Bulgaria – the Devnya industrial zone – within its natural boundaries – the lower part of the Provadiyska river catchment basin, down to its river mouth in lake Beloslav. Using landscape-geochemical research methods, the specifics and the conditions of migration and differentiation of heavy metals in soils (being an informative component of the landscapes) have been revealed. An attempt of determining the concentration of heavy metals, their radial and lateral differentiation in both relatively unaffected and considerably affected by human impact landscapes has been made. Some of the problems associated with the introduction, transformation and accumulation of technogenic substances in the studied landscapes have also been examined. The results are compared with those of similar research, carried out in the above-mentioned area 20 years ago.
