The problem of environmental distortion is relevant for industrialized areas due to the significant deterioration of almost all population health indicators, especially in children. Among the significant variety of environmental factors affecting the human body, chemical factor has leading positions, in the spectrum of which heavy metals (HM) take a special place and, above all, such a global and potentially dangerous toxicant, as lead. The purpose of the study was to determine the content of lead, as abiotic, and copper and zinc, as biotic metals in the blood of children living in the industrially tense areas. Mathematical treatment included the calculation of primary statistical values and the establishment of relationships among the variables. Despite the low levels of external exposure to lead, biomonitoring studies indicate a significant internal contamination of children bodies. The average values of lead content in the blood vary from 15.6 μg / dL to 45.9 μg / dL, which are significantly higher than the existing standards and are detected in 50-100 % of examined children. The content of lead in the blood of children of industrial regions is statistically significantly higher than that of the control region children, which proves its technogenic origin
