Abstract
Introduction. The content of heavy metals (such as Pb, Cd, Zn, Cu) and arsenic in soils, snow cover, and water has been monitored in the Sherlova Gora mining area. The geochemical specificity of mining landscapes directly determines the incidence in the local population. Establishing a dependency between these two indices is an important medical and biological task. Material and methods. The 120 soil samples were analyzed for the total content of lead, cadmium, zinc, and copper during 2012-2015. The analysis of the newly diagnosed incidence in childhood (0-14 years) and adolescent (15-18 years) population of the village Sherlova Gora was carried out according to statistical form No. 12 “Information on the number of diseases registered in patients living in the area of medical organization service” for 2012-2015. Results. The excess of maximum permissible concentrations (MPC) of arsenic and cadmium in samples of drinking water were revealed. For samples of soil, snow and surface water of the tailings dump ponds located near the settlement, a significant excess of arsenic and metals MPC was established. The total soil contamination index (Zc) at monitoring points was calculated taking into account the average concentrations, and it is less than 16 units, which corresponds to the “permissible” category of soil contamination. Conclusion. The children of the village were found to have cardiovascular morbidity by 7.0-15.3 times and a disease of the central nervous system (CNS) by 3.07-5.06 times more if compared with the administrative area. For adolescents, there was an excess of the incidence of cardiovascular pathology by 2.33-5.0 times, CNS - by 3.01-5.57 times, gastrointestinal tract by 2.6-4.9 times, urogenital system in 2.0-2.2 times. The prevalence of congenital anomalies is 6.9-15.6 times higher than the average margin.
