The Level of Trace Elements Shown by Children of Russia's North

Trace element status of the seaside and continental children's population of European and Asian North of Russia was studied. Hair samples were examined using atomic emission and mass spectroscopy with inductively coupled plasma (ICP-MS/ICP-AES) from laboratory of Centre for Biotic Medicine (Moscow). The data obtained in different territories were similar (decreased hair Se, Co, Cr, Ca, Mg, J, Mn, and Fe levels). This fact suggests common reasons for elemental status formation, which can occur due to particular biochemical properties of the environment and children's biochemical adaptation to conditions of northern climate. The established mineral imbalance showed by children can predispose them to so-called "geographical pathology".
