| Abstract: | Evaluations of the mean normal, increased, or decreased concentrations of macro- and trace elements in human body and biological media (e.g. hairs) are discussed. It is proposed that the element composition in an individual (mean normal, increased, or decreased) be evaluated by comparison with the mean level for the region, which depends on the biological, geological, and chemical (soil, water, etc.), ecological, climatic, and geographical factors. The efficiency of such an approach is demonstrated by forensic medical and clinical physiological findings. |
