Hair Samples

Hair is one of the promising non-invasive samples for monitoring the trace element composition of the human body. But it is necessary to take into account the individual and subpopulation characteristics of sample donors. Inthis work, we experimentally studied the features of the analysis of human hair samples for the determination of trace elements by arc atomic emission spectrometry using a dry residue after acid mineralization. Validation was carried out by comparative analysis by the method used, as well as by atomic emission spectrometry with inductively coupled plasma. It has been shown that the concentrations of Al, B, Ca, Cu, Fe, Mg, Mn, P, Pb, Zn in a set of 50samples from different donors obey the lognormal law, and therefore, the geometric mean (or median) is preferable as mean value. The content of Ca and Mg is higher in the female hair, while the content of Pb is higher in the male hair. Theconcentrations of Fe, Mn, and Pb are slightly higher in the hair of smokers than in non-smokers, but this difference is not statistically significant (probably due to the small sample size). Although the concentrations of several elements (including Mg, Mn, and P) differ in the hair of donors living in different regions of Russia, we failed to establish asignificant difference of this factor. Positive correlations were found between the contents of some elements, in particular, Mg/Ca, Al/Fe, Al/P, Cu/Fe, Cu/P, Fe/P, weaker relationships were found for Al/Cu, Ca/Mn, Cu/Pb, Mn/P.

Among the chemical elements contained in small quantities in mineral waters, of interest are trace elements that have a certain biological activity. According to the method developed by us, the content of copper, nickel, zinc, cobalt, chromium and manganese in certain mineral waters of Western Georgia was determined. The obtained data on the content of trace elements in mineral waters are of practical value, information about the trace element composition will contribute to the further study of these waters in hydrogeological, hydrochemical and balneological aspects.

Endocrine Regulation

There are more than 70 chemical elements in the human body. To date, the need for more than 20 trace elements has been determined: deficiency in them leads to disruption of the neural, immune and endocrine regulation and adaptive potential, increases the risk of infectious diseases and development of their chronicity. A prolonged absence of certain nutrients in the diet, or vice versa, excess of them in soil and water, can cause irreversible changes in the body. The article discusses physiological role of minerals, macro and micronutrients, features of their metabolism, content standards, causes of their shortage in the diet. Recommendations on the choice of material for the study of the trace element composition are given and possibilities of modern laboratory diagnostics are presented.
