Biogeochemical Factors Affecting The Health Conditions Of The Mother And Child

Abstract

In recent years, much attention has been attracted by the study of the content of trace elements in the natural environment (soil, water, plants, food), which makes it possible to give a comparative hygienic assessment of the degree of availability of various environmental objects with bioelements. The heterogeneity of the qualitative and quantitative chemical composition of individual geographic zones found its expression in the teaching of A.P. Vinogradov (1983) on biogeochemical provinces. In this regard, the concept of biogeochemical endemics resulting from an excess, deficiency or imbalance of trace elements in the environment was born
