In blood of children underwent to the long-term isolated exposure of manganese and stable strontium with drinking water exceeding the acceptable level by up to 1.4 times the elevated concentrations of mentioned metals in blood were shown to be formed in relation to reference level by 2,0-4,4 times. The developing at that mutagenic effect was proved to have the dependence on the level of manganese and stable strontium concentration in blood and is pronounced in the increased rate of cells with cytogenetic anomalies on the background of the enhancement of the proliferative activity, destructive changes in the cell population and oxidative responses at the cell DNA level. The activity of genetic instability and processes of DNA oxidation in the somatic cells in children under the exposure to manganese has more pronounced character in comparison to given indices under the exposure to the stable strontium.
