ABSTRACT. The role of chemical elements contained in the biosphere (soil, plants, water) in the development of hypertension and cardiovascular disease is studied insufficiently. It is known that cardiovascular mortality in the United States, the UK, Finland correlates with soil types, which differ greatly in their content of chemical elements. According to local researchers from the Tambov region, there is a positive correlation between the strontium content in soil and the prevalence of essential hypertension; between the strontium, titanium, chromium, nickel and the risk of coronary heart disease; between the deficiency of copper, zinc, cobalt and the risk of endocrine diseases in Dagestan. The aim of the present study was to investigate the chemical composition (Mg, Zn, Cu, Mn, Co) of some biosphere objects in comparison with prevalence of hypertension among the population living in the West Caspian region of Dagestan. To detect the connection between environmental concentration of elements (Mg, Zn, Cu, Mn, Co) in the biosphere and hypertension, we have investigated samples of soil, plants and water, collected in lowland areas of Dagestan (Babayurt, Kizlyar, Tarumovsky and Nogai administrative districts). The Co, Zn, Cu, Mn, Mg concentrations in soils, plants, natural waters were determined using a Hitachi 170-70 atomic adsorption spectrophotometer. When comparing hypertension morbidity statistics for the recent decade (2000-2009) from the Republican Medical Center for Information and Analysis at the Ministry of Health of the Republic of Dagestan with the environmental content of chemical elements in the West Caspian region of Dagestan, it was found that the lower the concentration of Mg, Zn, Cu, Co and the higher the Mn, the higher the incidence of hypertension in the population.
