Sažetak
The subject of this study are the soils(calcomelanosol, calcocambisol and regosol) in the area of the Neretva River Delta around the Kuti Lake. The objective of this work was to determine geochemical and mineralogical properties of calcomelanosol, calcocambisol and regosol for better understanding weathering processes of source materials. Chemical, mineralogical and geochemical analysis of the collected soils were carried out in order to determine their properties, such as soil reaction (pH), electrical conductivity, content of carbonates. Organic material was removed from the fraction <2 mm using two methods, H2O2, and NaOCl. Following that, the content of TOC was measured in order to determine the effectiveness of these two methods. The presence and importance of Fe-oxide was measured using the dithionite and oxalate treatment. Mineralogical characteristics were determined by the help of XRD. Sequential extraction analysis was made to determine the main binding site of trace metals in the soil, and evaluate their ability to evaluate the bioavailability and remobilisation. The analyses were performed according to the BCR procedure and proportions of elements were determined in four fractions: (1) carbonate, (2) the fraction of Fe-Mn oxide and hydroxide, (3) organic-sulphide, and (4) residual fraction. The following elements were measured: Cu, Mn, Zn, Co, Cd, Ni, Cr, Pb. The extracts obtained by dithionite treatment, oxalate and the sequential extraction analysis were measured by atomic absorption spectrometry. Calcomelanosol and calcocambisol soils have slightly acid pH, while in regosol is slightly alkaline. Proportion of well crystallized is higher than poor crystallized Fe oxides. Phyllosilicates are dominant mineral phase in calcomelanosol and calcocambisol. Beside this mineral, quartz and mica minerals are also present in analysed soils. Most of analysed elements are bound to residual fraction. Cadmium has higher concentration in organic sulphide fraction.
