ABSTRACT
Due to naturally occurring arsenic in the sediments the groundwater in the south part of Russia content high level of arsenic contamination and more than 500 thousands of people might be at a considerable risk of chronic arsenic poisoning. The evaluation of cancer risks from oral exposure to As were found to be above the acceptable U.S. EPA and WHO cancer health risk range of 1 × 10−6 to 1 × 10−4. A relatively high content of arsenic in the hair of the people surveyed was found. The results of this study allow us to reveal areas in region with high levels of arsenic in drinking water, determine the exposed population to the implementation of risk mitigation measures and also direct correlation between the arsenic content in drinking water and its content in the hair of the exposed people.
