ABSTRACT. A study of the elemental composition of hair of 88 children aged 0–17 years living in the territory of the city of Sibay, Republic of Bashkortostan. It was revealed that among children and adolescents living in the biogeochemical province in a city with a developed mining industry, there are cases of increased content in the hair of manganese and zinc. A significant number of children aged 1 to 14 years showed a reduced content of such essential macroelements as calcium (35.2%), magnesium (33.3%) and phosphorus (27.8%), and in adolescents – potassium (36,4%) and phosphorus (in 27,3%). Reduced levels of trace elements (Cu, I, Co and Cr) were found in all newborns, as well as Mn and Zn in 41.5 and 8.3% of cases, respectively. Also, the deficiency of Zn (in 33.3% of cases), Cu (in 9.3%), I (in 42.6%), Co (in 85.2%) and Cr (in 64.8%) was registered in children 1–14 years. Almost all surveyed adolescents aged 15–17 years were found to have a reduced level of Se and Co (100 and 90.9%, respectively), more than half (59.1%) – I, 18.2% – Mn, 27.3% – Cr. Cases of increased content of Mn and Zn in the hair were revealed. Based on the obtained data on the content of chemical elements in hair it can be concluded that diselementoses are widely distributed in the studied region and make a negative contribution to the deterioration of children's health.
