Chukotka natives live in different climatic-geographical zones. Their nutrition chains are also different: in tundra population the chain is soil-land moss-venison-man, in coastal population it is sea-mammals, fish-man.

Materials and methods: Tundra and coastal native populations of Chukotka were investigated (156 subjects correspondingly). The element composition of blood was measured by the SRXRF method. Results: In coastal Chukotka natives as compared with tundra population the content of the following elements is more for certain: K, Mn, Cu, Se, Br, Y. And for sure less is content of Cr, Ni, Ga, Rb, Bi and U (p<0.05), mercury was not studied in coastal population. In tundra for sure different in men and women are the following elements: K, Fe, Zn, Rb, U. Accumulation of Sr and Pb increases with age, but content of Ni and Se decreases with age. In coastal population Br, K, Mn, Fe, Cu, Zn, Ga content increases with age and Cr content decreases with age.

The content of chemical elements in fish is not higher permissible values, but Hg content is 0,6 instead of 0,3 and Pb content is 1.0 instead of 0,6 mkg/g (2 times and 1.5 times were correspondingly). The water of Kanchalan river contains more Cr, Mn, Fe, Ni, Pb and less K, Ca, Co, Br, Sr, U in comparison with the water of Baikal lake. In the water of Kanchalan river the content of Zn, Br, Sr, Pl is higher according to our investigation.

Conclusion: Thus, peculiarities of chemical elements content in blood according to age and sex were revealed in Chukotka natives. The content in blood of the most of chemical elements decreases with age, but rare elements are accumulated. The water of Kanchalan river contains more Zn, Br, Sr, Pb, the content of Pb and mercury in fish is higher. All these factors influence the chemical elements blood composition in Chukotka natives.
