To investigate the status of mineral metabolism in people residing in huge regional centers of north-western and north-eastern parts of Russia by AES-IBP (atom-emission spectrometry with inductively bonded argon plasma), the content of 25 elements in hair samples of surveyed people was examined. The results of the study carried out in Russia's north could testify to significant deformation found in the elderly people bodies' element profiles. The pronounced deficit in such essential elements as Ca, Cr, Mg can be considered the common north-related profile typical for the elderly people from European and Asian north. In addition, age-related formation of all the elements' deficit due to their risen spending at pathologies as well as the increased need in such elements as Zn, Se, Cr, Cu, Mn. The age-related excess of arsenic proved to be typical for Magadan residents. In Anadyr, the age-related excess of lead was found, in Petrozavodsk mercury, and in Arkhangelsk--boron and aluminium. 展开更多
