BACKGROUND LEVELS OF TRACE ELEMENTS IN THE SOILS OF ZITNY OSTROV, SLOVAKIA

Rok, strany: 1993, 107 - 114

Fifteen soil profiles of the area of Zitny ostrov have been investigated and the variability in the natural background of eighteen trace elements, viz. Ag, As, B, Ba, Be, Cd, Co, Cr, Cu, Ga, Hg, Ni, Pb, Sr, Sn, V, Zn and Zr has been examined. Analyses have been performed mainly using optical emission spectroscopy and atomic absorption spectrometry. Comparison shows a relative tendency of the studied soils toward enhanced values with regard to B and Cd, and depletion to Ba, Cr, V and Zr.The frequency distributions of the elements are positively skewed, and transformation of the data to their natural logarithms was effective to reduce the skewness and kurtosis values significantly, and to approach normal distribution more closely. The contents, thus, appear to be mostly log-normally distributed, and they were described in terms of log-derived mean and normal range. Statistically, no geographical relation have been found with the levels of the studied trace elements, with the exclusion of few elements in case of As, Pb, Zn and Zr, but there is a relative accumulation of some trace elements in the middle and lower parts of the area.
