Bioaccessibility of potentially toxic elements in surface geochemical media of dispresion for the environmental risk assessment at mining areas of NE Chalkidiki

Abstract

This Thesis focuses on the evaluation of the present status regarding the concentrations of potentially toxic elements in surface geochemical media of dispersion and the transport mechanisms from the geosphere to biosphere at the metalliferous region of NE Chalkidiki peninsula, including the wider mining area of Stratoni village. Stratoni comprises the only case of mining and processing of sulphide ore in Greece. Currently, the Mavres Petres sulfide ore deposit is mined whereas one of the future mine development plans is the Skouries project. The aim of the present Thesis is the development of a methodology that will contribute to the environmental risk assessment by determining the origin, concentration, mobility and fate of potentially toxic elements, according to the model: source – pathway – target.Geologically, the studied area consists of the metamorphic rocks of Kerdylia and Vertiskos geotectonic units which have been intruded by Tertiary magmatic rocks. Various ore deposits are ...
