MEDICAL AND SOCIAL ASPECTS OF NATURE MANAGEMENT. THE QUALITY OF DRINKING-WATER (THE CASE OF SOUTHERN AREAS OF THE AMUR REGION)

At present the methods of the integral evaluation of the geoecological state of underground waters considering a complex of factors are being improved. Among these factors the evaluation of drinking-water quality is the most important. The quality issue is urgent for the Amur Region. The research is conducted by multi-factor analysis with the consideration of natural conditions of the region, current normative indices and the evaluation of water safety for drinking. It is demonstrated that the chemical composition of underground waters and hydrochemical zoning are the reflection of geological-structural and geodynamic features of the region. Basing on the studies of macro and micro element composition of drinking-waters within the most economically developed areas of the Amur Region we identified the natural geochemical background and singled out the areas and settlements with high concentration of contaminating elements as well as the zones of higher risk for human health. The main natural chemical contaminants of drinking-water affecting the health of the population were identified. It was found out that for the last 15 years the level of the morbidity among adults of Tambovka area, which is known to have high concentrations of some elements, has been 1.5 times higher than the regional one. The analysis of the morbidity by ICD-10 classes revealed statistically reliable differences (at р<0.05) which exceed the limits of standard deviations from the average level of the regional rural population morbidity. So, the level of morbidity in Tambovka area exceeds the regional one by 85% in blood diseases, by 82.6% in infectious and parasitic diseases, by 81% in endocrine diseases, by 82% in congenital anomalies, by 70.7% in musculoskeletal system and connective tissue diseases, by 70.2% in nervous system diseases, by 65% in digestive apparatus diseases, by 54% in the blood circulation system diseases, by 50% in tumor, by 43.5% in dermic and hypodermic tissue diseases.
