Abstract

Sediment samples from the tributaries of lake Balaton were analysed. Samples were collected in spring, summer, and fall in 1997/1978. Mineralogical composition, major and trace element contents of the sediments were determined in form of solid phase, applying X-ray powder diffraction (XRD) and X-ray fluorescence spectrometry (XRFS). Major analytes were Al2O 3, CaO, Fe2O3, K2O, MgO, Na 2O, P2O5, SiO2, and TiO2, while trace elements included Cr, Ni, Cu, Zr, Sr, Y, Rb, Zn, Pb, As, Ba, and S. The results of sediment samples from north and south shores and from the tributaries of the lake were interpreted separately both in terms of the mineralogical and chemical compositions. The major- and trace element contents were compared to a standard reference data set (PAAS) for sediments and data were evaluated using a correlation matrix via statistical calculation of all data on the elements measured. Based upon the results it was concluded that there was no serious anthropogenic contamination in the tributaries. Higher concentrations of some elements were found in cases of some tributaries. Conclusion regarding to the relation between mineralogical composition and trace element content are independent of the site and time of sampling.
