RISK ASSESSMENT OF CHILDREN’S HEALTH DUE TO THE CHEMICAL COMPOSITION OF DRINKING WATER SOURCES OF THE NON-CENTRALIZED WATER SUPPLY OF THE CITY OF EKATERINBURG
Introduction. In recent years, the risk assessment methodology has become the leading tool for assessing the health of various groups of the population, allowing identifying priority negative environmental factors. Material and methods. There were explored 212 wells, including 150 in collective gardens and 62 in cottage settlements. The priority oral route of chemical intake into the body was studied. Results. Nitrates and arsenic compounds create the main non-carcinogenic risk in the sources of non-centralized water supply in the territory of the Municipal Settlement of the city of ekaterinburg. When using water from wells in cottage settlements levels of non-carcinogenic risks are significantly lower than non-carcinogenic risks in horticultural partnerships. Acceptable level of non-carcinogenic risk for children under 6 years are related with 17.4% of water sources in collective gardens and 25% of wells in cottage settlements; for adults - 60.8% and 93.8% respectively. The detected nitrate concentrations in individual wells of horticultural associations can create a high non-carcinogenic risk. The total individual lifetime carcinogenic risk, both in the water of collective gardens and in the water wells of cottage settlements ranges from 10-5 to 10-4 and, therefore, is at a low level, the greatest contribution is made by arsenic compounds. Discussion. In contrast to the earlier traditional assessment of drinking water quality, when the main substances for which the discrepancy was found to hygienic standards were manganese, nitrates, iron and silicon, in the assessment of water danger using the methodology of risk assessment, nitrates and arsenic come to the first place, with a much smaller role of manganese. The calculation of carcinogenic risks using age correction factors (ADAF) has increased the risk values calculated by the traditional method by almost 2 times. Summary Levels of non-carcinogenic risks when using water from wells in cottage settlements are significantly lower than non-carcinogenic risks in horticultural partnerships.
