Streszczenie
Zinc and manganese are essential trace elements (they are constituents of body fluids, various tissues and organs and are involved in many biochemical processes that support life etc.); however, deficiency or excess intake or disturbances in metabolism may lead to diseases and toxicity. For this reason, data on the reference concentrations of zinc and manganese are important to estimate. In this paper, the concentration of zinc and manganese in human tissue (brain, liver, kidney, stomach, small intestine, lung and spleen; total n = 47) and body fluids (blood, urine, bile; n = 29) obtained from autopsy cases of non-poisoned people (22 males and 8 females, aged 18–56, mean 33.5 years) by flame atomic absorption spectrometry (FAAS) and inductively coupled plasma atomic emission spectrometry (ICP-OES). The data obtained by the two methods do not vary significantly (Kruskal-Wallis ANOVA test). The accuracy of the methods was checked through the use of standard reference material, Bovine Liver 1557b.
