SANITARY-HYGIENIC EVALUATION OF THE QUALITY OF DRINKING WATER IN THE KHASANSKY DISTRICT IN THE PRIMORYE TERRITORY
This study presents an assessment of the risk of sanitary and chemical indicators in the drinking water of the Khasansky district for the period 2014-2016. The greatest risk of olfactory-reflex effects associated with the turbidity of the water source was determined in the water entering the distribution network from the surface source of drinking water supply of the Lake. Hassan. Analysis of chemicals in drinking water from this source, revealed exceedances of maximum permissible concentrations for manganese and iron. The hazard ratio was the maximum for iron and arsenic in drinking water in 2016 in calculations for the child population. The results of assessing the non-carcinogenic risk of chemicals in drinking water have revealed a direct positive correlation between the concentration of arsenic and the incidence of adult population in the area for skin and subcutaneous tissue, and for children between the concentration of iron in water and diseases of the circulatory system.
