ABSTRACT. Arsenic content in the hair of inhabitants of settlements of North Dagestan using artezian water as a source of drinking water supply with arsenic content higher than the hygienic norm is analyzed. A relatively high content of arsenic in the hair of the people surveyed was found, which is probably due to the hydrogeochemical features of the region under study. Preliminary studies of the hair arsenic content in exposed citizens of the North Dagestan confirm the assumption of arsenic cumulation in the body due to chronic oral exposure in the studied population group. In the region with the highest arsenic content in drinking water (0.40.5 mg / l) in 10% of the examined people - its content exceeds the threshold value in the hair, at which clinical symptoms of arsenoses (including arsenodermatitis) can be observed; in 58% of the examined individuals, the arsenic content in the hair is at the background level; in 32% the arsenic content was found to be 0.50.9 μg / g, which indicates accumulation, but does not reach the threshold value. The results of this study allow us to reveal a direct correlation between the arsenic content in drinking water and its content in the hair of the inhabitants.
