The aim is to assess hair macro- and microelement profile of young men - residents of the city of Anadyr, Chukotka Autonomous District Arctic Russia among indigenous and Caucasoid populations. Methods: atomic emission spectrometry and inductively coupled argon plasma mass spectrometry we used to assess concentrations of 25 elements, namely, Al, As, B, Be, Ca, Cd, Co, Cr, Cu, Fe, Hg, I, K, Li, Mg, Mn, Na, Ni, P, Pb, Se, Si, Sn, V, Zn in the hair of randomly selected indigenous and non-indigenous residents of Anadyr. Results. We observed a so-called "northern" element imbalance with the tendency towards deficiency of the basic essential chemicals. Individual concentrations of the most chemical elements in the hair were highly variable. Proportions of participants with low levels of elements in the body of the Caucasians significantly exceeded that in among the indigenous people. Conclusions. Ethnic variations in the hair microelement profiles were minor reflecting similarities in the structural profile of macro- and microelements. The difference in the concentration values from the reference values may be considered as a reflection of the characteristics of the genetically determined system of maintaining the balance of the body's element system in the indigenous peoples of the north and adaptation to extreme climatic and socio-ecological conditions in case of Caucasians living in this Arctic region for several generations.
