The current article demonstrates the results of a comparative trace element analysis of biosubstrates (hair, blood) of thechildren population of the Eastern, Western, and Central zones of Orenburg Oblast. The article demonstrates that the elementalstatus of children in the different zones of Orenburg Oblast differs to a significant degree. The highest content of toxicelements in the hair was observed in children living in the Eastern zone, and in the blood of children in the Western zone. Inchildren living in the Eastern zone, the content of Sr, Ni, and Co is higher than the regional values, while the content of Cr islower. In the blood of children of the Western zone, the content of chromium and lead is 1.5 – 2 times higher than regionalvalues, while the concentration of other elements is at the level of regional values. In the hair and blood of the children livingin the Central zone, the study observes an increased content of Cr and Sr with a reduced content of Co. It is noted that acommon feature of the elemental status of children is that Co – Ni – Cr and Pb – Sr associations are clearly distinguished in theblood, and especially in the hair of children. The authors of the study assume that these interactions between the elements aredue to competitive relationships and synergism of metal cations. The imbalance of trace elements is caused not only by theecological and geochemical features of the territories but also by the mutual influence of the elements.
