Resumo

Hygienic assessment of drinking groundwater used for drinking water supply by the population of the Northern part of the Republic of Dagestan for several decades has been carried out. The content of arsenic in drinking water sources was found to be up to 50 times higher than the permissible WHO standard. The use of regional factors of water consumption allowed to calculate individual and population carcinogenic risks to the population during long-term use of groundwater for drinking water supply. It was shown that the individual carcinogenic risk was 4,3E-4 at the minimum concentration of 0,01 mg/L; 2,1E-2 at the maximum concentration of 0,5 mg/L, and 6,0E-3 at the average value of 0,14 mg/L, respectively. The identified levels of lifetime individual carcinogenic risks (over 70 years) exceed the «acceptable» (target) level of 10-5 and are assessed as unacceptable for the preservation of public health. For the exposed population of the studied regions of Northern Dagestan (309,7 thousand) the values of population annual carcinogenic risks, reflecting the additional (to the background) number of cases of malignant neoplasms that can occur during the year, ranged from 1 to 95 cases. The results of this study allowed to identify areas with high levels of arsenic in drinking water and to identify the exposed part of the population for the implementation of measures to reduce the risk. To assess the population’s exposure and establish a link between exposure to arsenic and its accumulation in humans, the biomonitoring has been conducted, the results of which allowed to identify the correlation between arsenic content in hair of residents and it’s exhibited content in consumed drinking water.
