Analysis of the relationship of biological isotope fractionation with features of metabolic processes occurring in organisms, ecosystems and products technogenesis. The complexity of such analysis does not diminish its necessity and urgency, identify the isotopic displacements C, H, N, O, S, Ca, Mg, Fe in cells and tissues of organisms as a possible indicator of its functional (biological) activity. The presented research attempts both theoretical and practical generalization heobiohimichnyh and environmental knowledge that is different-and Applied different disciplines - from geology and geochemistry to biology and clinical medicine. Actuality health problems caused by the natural environment, due to the spread of contamination which decreases the biological activity of organisms and the development of pathologies. The isotopic shift of carbon and other nutrients in the cells of living beings are regarded as possible indicators of these changes. It is assumed that all biological systems under normal conditions of life characteristic isotopic metabolism processes in which there are variations in the isotopic composition of certain nutrients. The emergence of living organisms lesions of various etiologies, including those caused by increased anthropogenic impact on the environment, accompanied by a violation as the mechanism and intensity isotopic metabolism. From this point of view, studied in detail two biogenic elements - hydrogen and carbon. The notion of "isotopic metabolism" and "isotope zoning" and that mention me in the biosphere natural and man-made zones. The mentioned these concepts and their relevance is justified.
