ABSTRACT. One of the main factors for the degree of adverse effects on humans is a lack of macro-and microelement intake, a violation of their ratios in the diet, which directly effects on the body's activity and may manifest a decrease in resistance and ability to adapt. In the course of the investigation on the elemental status of the children population, a study was conducted on the selected hair samples of Buryat nationality children of the preschool age living in Ulan-Ude. Fifty children of preschool age (4–6 years). Analysis of the available data on the quantitative content of chemical elements in the hair of preschool children showed that, there is a significant spread of insufficiency of essential macro- and microelements in general, primarily iodine (in 70.5% of those examined), silicon (43.2%), and magnesium (27.3), zinc (47.7%), copper (84.1%), cobalt (79.5%). There is also a fairly high occurrence of excess phosphorus (25%) and boron (45.5%), sodium and potassium (60%), calcium (18.2%). Comparison of the results of multi-element hair analysis with height, weight and body mass index (BMI) of preschool children shows that these anthropometric parameters correlate negatively, mainly with the content of ecotoxicants in the hair and positively with the level of magnesium and zinc essential elements.
