[The habitat and environment-induced imbalance of trace elements in the populations in the population of urban and rural areas].

A comprehensive hygienic assessment was made of natural and anthropogenic risk factors and conditions for trace element deficiencies in the populations of urban and rural areas. All chemicals identified were evaluated in the environmental objects. The mean daily absorption dose for the population was estimated. The paper presents a comparative analysis of the concentrations of Cu, Fe, Zn, Pb, Mn, Ni, Cr, Co, Cd, Sr in the biological media (hair, blood, bone tissue, placenta) in the populations of an industrial town and rural areas and their levels in some abnormalities and also compares the spectral composition of trace elements in the hair and blood with that obtained by other authors.
