Hygienic aspects of lead osteotropicity as a risk factor of calcium-deficit pathology in man (literature survey)

For today problem of chemical contamination of the environment and inner enviroment of the organism is extremely topical. Among all toxicants scientists pay special attention to lead, as it is characterized by a global prevalence in the enviroment and polytropic action on the human organism. Aim of the work ? on the basis of analytical generalization of research data to establish peculiarities of lead impact on formation and functioning of bone tissue, calcium balance in the organism. It was determined that despite a low external exposure of metal, in man’s biosubstrates its levels are much higher than allowable. Herewith bone tissue due to its anatomy-physiology peculiarities accumulates lead selectively, forming inner additional source of its impact on the organism, potentiating toxic impact of xenobiotic. Therefore biomonitoring data on lead content in bone tissue is an important informative finding not only of danger but of duration, permanence and complex impact on the organism.
