Abstract: | Contents of mineral substance, silica, and a range of bioelements and toxic elements (Mg, Na, K, Ca, Ba, Zn, Cr, P Al, Cd,
Mn Cu, Ni, Pb, Sr, Fe) in 38 livers of donors from the Upper Silesia Coal Basin (southern Poland) are presented. Elements
were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) with the exception of silica that was
estimated colorimetrically. Concentrations, concentration variability, and correlations between selected liver components
determined for the total population are related to donor age, gender, and lesion occurrence. Correlations between particular
elements were found using correlation coefficient values and the Fisher transformation. Mineral substance in the livers lies
in the range 0.40–5.03 wt%. With increasing donor age, mineral-matter content decreases to a minimum for the 40–60 years of
age range. Microbioelement contents show a similar tendency, while microbioelements and toxic elements reach maximum contents
in donors aged 60–80 years. All elements show content decreases in livers from the oldest group (>80 years). Silica contents
increase with age. Variability of element contents is lowest in the older subpopulations. Livers with lesions show lower element
contents and variability. The results are compared to literature data for regions of Poland assumed to be of low pollution
and to data from comparable regions in Japan and Hungary. Up to our knowledge, this paper is the first work describing the
total contents, as distinct from contents of selected elements, of mineral substance in human livers. |
