ELEMENTAL STATUS OF ABORIGINAL ETHNIC GROUPS IN NORTHEASTERN RUSSIA ^{[№ 5 ' 2016]}
Purpose to work is to study the characteristics of the element status of ethnic indigenous groups of the North-East, Russia and the establishment of the main factors ensure the mineral metabolism. We presented the results of a study level trace elements in the indigenous groups of the North-East of Russia — Koryak, Chukchi, Evens. Elemental status was assessed by quantifying the elements in hair by atomic emission and mass spectrometry with inductively coupled argon plasma at the Center for Biotic Medicine (Moscow). The content of 25 chemical elements: aluminum, arsenic, boron, beryllium, calcium, cadmium, cobalt, chromium, copper, iron, mercury, iodine, potassium, lithium, magnesium, manganese, sodium, nickel, phosphorus, lead, selenium, silicon, tin, vanadium, and zinc. Statistical analysis was performed using "Statistica 6.0" program. Some of the elements that had a significant between-group differences (p < 0.05) was taken for analysis. A higher content of Na, K, Fe, I, Cr was observed in the group compared to Evens Chukchi. The lower the content of Cu, Si was found in the group with respect to the Koryak and Chukchi, Evens. At aboriginal residents marked deviation with respect to some elements of the reference values. Thus, in the Koryak reduced content of Cr, I, the Chukchi — K, Na, Cr, I, Evens — I. Evens increased content of Na and K. We have considered the possible consequences of deficiency and excess bio-elements in the body of native inhabitants. Common elements in the ethnic group "Koryak — Chukchi" are the Na, K, Fe, I, Cr. Group "Chukchi — Evens" combined Cu and Si. The content of most of the investigated elements comparable in the Koryak and Chukchi, and significantly different from their performance in the Evens. It has been suggested that mineral metabolism traits in indigenous ethnic groups of the North-East of Russia are genetically determined.
