Abstract: Trace element geochemistry of six soil profiles down to subsoil has been investigated at Mezőnagymihály. Differential thermal analysis was applied to determine organic content, carbonates and clay minerals, and pH was measured.
Optical emission spectrometry provided half-quantitative data of 13 trace elements.
Soluble quantity of 5 trace elements (Mn, Zn, Cu, Pb, Cd) was determined
by atomic absorption spectrometry. Ratios of trace elements in A-, B- and C-levels were compared, a trace element ecological picture of the area was formed and correlations were calculated for soluble trace elements and other parameters (pH, carbonate content, clay mineral content). Highest correlation is shown by soluble
Zn and Pb. High correlation was calculated for Mn-Pb, Zn-Cu, and Cu-Pb pairs, too. High correlation was found for soluble quantities of Zn and Cu and the pH, while there is a low correlation for Pb and pH and no correlation coula be proved for Mn and pH. Soluble Zn, Cu and Pb display high correlation with the quantity of organic matter, while Mn does not. No high correlation could be proved for soluble element concentrations and clay mineral content; also, low correlation was shown for trace elements and carbonate content.Journal: Fragmenta Minerologica et PalaeontologicaJournal abbreviation: ISSN: 0367-2697Publisher: Múzsák Közművelődési Kiadó, BudapestEditor(s): Vörös, A. & Nemes, I.
