The pollution of the living environment is a significant factor leading to the undermining of the health of the indigenous people of the North. The issue had appeared in the context of alluvial diamond mining in the Arctic territories and the field development of rare earth metals. The study included 107 indigenous people of the North, belonging to the Dolgan ethnic group, living in the village of Yuryung-Khaya, Republic of Sakha (Yakutia). The content of 13 elements in blood serum (P, Sc, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr, Cs, Pb) was studied by mass spectrometry (ISP-MS). The study revealed in Dolgan serum an increased content of the macro element – phosphorus (148 mg/l) and trace elements – chromium (277 μg/l), manganese (133 μg/l), iron (5219 μg/l), nickel (57 μg/l), which can affect the development of diseases in indigenous people of the Arctic under the conditions of commercial development of settlement area.
