Среди наиболее значимых факторов окружающей среды, оказывающих неблагоприятное действие на организм человека, питьевая вода, наряду с атмосферным воздухом, занимает особое место, при этом ее химический состав во многом определяется качеством воды природного водоисточника [18,19]. Проведенный анализ свидетельствует о том, что в пробах воды поверхностных водоемов, расположенных вблизи существующих и отработанных месторождений полезных ископаемых, наблюдается повышение по сравнению с нормативными значениями концентрации загрязняющих веществ.…”

Introduction. The supply of high quality potable water to the population living within the geochemical provinces remains an important problem since the imbalance of chemical elements is a risk factor for various diseases and syndromes. The purpose of the study was to analyze the quality of surface and groundwater related to the geochemical characteristics of the region and to assess public health risks. Materials and methods. Water quality was analyzed in the areas of the Zabaykalsky Krai characterized by the presence of geochemical anomalies. Non-carcinogenic risk assessment of combined exposure to multiple chemicals in drinking water was carried out in accordance with the requirements of R 2.1.10.1920–04. Results. We established the excess of maximum permissible concentrations for such elements as iron (1.1–5.1 MPC), fluorides (1.1–2 MPC), nitrates (2.2 MPC), manganese (5.1 MPC), zinc (2.5–4.6 MPC), and cadmium (1.3–1.5 MPC). Higher than acceptable values of non-carcinogenic hazard quotients were attributed to the effects of nitrites (HQ = 1.5) and arsenic (HQ = 3.4) on the child population in the Kirinsky district. The total hazard index (THI) exceeded the permissible one for children in the Kyrinsky (5.05), Borzinsky (1.92), Chitinsky (1.19), and Tungokochensky (1.24) districts, the urban-type settlements of Zabaykalsk (2.07) and Priargunsk (1.62), and the towns of Petrovsk-Zabaykalsky (1.1) and Chita (1.87). Arsenic, fluorine, iron, and nitrites in water contributed the most to the risk level. Conclusions. The priority water pollutants included heavy metals, nitrites, arsenic, manganese, iron salts, and fluorides due to local natural geochemical features and industrial pollution. The assessment of the total non-carcinogenic risk based on hazard quotients showed that the children were at higher risk for toxic effects of those chemicals on the immune system, teeth, bone tissue, cardiovascular system, gastrointestinal tract, skin, reproductive, respiratory, and hematopoietic systems, liver, kidney, central nervous and musculoskeletal systems.

According to WHO, approaches based on the assessment of health risks are promising and should be used to justify management decisions to ensure the safety of drinking water. A review of publications on risk assessment in Russia showed that the main part of the methodological issues is related to the uncertainties in the evaluation of exposure, the lack of regional, national and age differences in exposure factors and sensitivity to carcinogens. In the Republic of Tatarstan, research was conducted for the first time on the regional factors of the exposure of drinking water consumption for adolescents aged 15-17 and adults (18-21) years in Kazan, Republic of Tatarstan. We studied the content of 19 priority chemical pollutants, including three carcinogens, in the drinking water of Kazan for 2010-2016. The HI value for oral intake of chemicals with drinking water indicates a health hazard for the adolescent population living in zones 2 and 4 (HIm = 9.8 and 8.8, HI 95percent = 8.1 and 7.6), and adults (HIm = 7.4 and 7.8, HI 95percent = 6.8 and 6.5). The priority pollutants of drinking water in all zones that determine the main contribution (71.6% - 87.6%) are petroleum products (29.7% - 54.0%), chloroform, nitrates, magnesium, as a total amount of non-carcinogenic risk of adolescent and adult population and fluorides.
