Abstract
Fluxes of trace metals in the extreme environments will be determined. The geochemical cycles in the industrial area in Slovenia (the Šalek Valley) and in active volcanic zone in Italy (Etna) will be compared. The research area in Slovenia is influenced by the human-induced sources and second in Italy is a natural source. In both environments the heavy metal contents are much higher than a normal one and thus can increase a human health risk. In industrial area of the Šalek Valley the increased input of metals is result of mining and coal combustion. In active volcanoes area of Etna the release of metals occur directly from magmatic fluids or indirectly through water-gas-rock interaction that enhances their leaching from volcanic rocks where they are usually abundant. Calculation of metal fluxes will take into account all possible types of sources and sinks for them. The study will focus on the geochemical cycles of the following heavy metals: As, Cd, Cu, Hg, Pb, Se, V and Zn. The data for estimation of geochemical cycles will be collected from the previous researches. Some additional chemical analyses of soil, air, water and plant samples will be done to complete the missing data. The results will contribute to the global estimation of metals fluxes and to a better assessment of their geochemical cycling.
