ASSESSMENT OF THE RISK OF NON-CARCINOGENIC EFFECTS ON THE HEALTH OF THE POPULATION OF KEZ SETTLEMENT IN THE UDMURT REPUBLIC WHEN DRINKING WATER IS CONSUMED FROM UNDERGROUND WATER SUPPLY SOURCES

Abstract

In the settlement of Kez, as in other rural settlements of the Udmurt Republic, the main source of water supply is groundwater. The quality of groundwater does not fully comply with hygienic standards. In order to determine the probability of development of general toxic effects on the health of the population of Kez settlement when drinking groundwater was consumed, a procedure for assessing non-carcinogenic risk was carried out. The study showed that the greatest danger to public health are fluorine compounds in groundwater (the average value of the risk level for the territory was 0.97), as well as the content of sodium ion in water (the average risk level for the territory is 0.81). As for the total risk level for all considered components in groundwater, it should be noted that in 19 out of 25 wells the risk level is dangerous, while in 9 of them the risk level exceeds the upper permissible limit by more than 2 times.
