“…При этом для нормального функционирования всех органов и систем человека крайне необходимо не только регулярное поступление в организм макро-и микроэлементов, но и правильное их соотношение. Дисбаланс отношения таких элементов как натрий-калий, кальций-магний, барий-стронций явно отражается на физиологическом состоянии человека и снижает сопротивляемость организма, а, следовательно, отражается на способности человека к адаптации [33]. По полученным данным в основной группе происходит снижение более чем в 2 раза соотношения Na/K и в 3 раза соотношения Ca/Mg.…”

Chemical homeostasis is a necessary component of maintaining health, and an excessive or insufficient level of macro- and microelements in the body is considered as a risk factor for the development of pathological changes. Purpose of the study: to study the possibility of determining the micro- and macroelement composition of saliva by capillary electrophoresis, and to assess the applicability of the data for monitoring the technogenic load on the human body. Methods: For the experiment, we used saliva samples of employees of the Omsk СHPP aged 25-45 years (main group, n=104) and healthy volunteers aged 23-25 years who were not related to the СHРP (comparison group, n=195). In all samples, the content of potassium, sodium, magnesium, calcium, lithium, strontium, barium and magnesium was determined by capillary electrophoresis. In all samples, the content of potassium, sodium, magnesium, calcium, lithium, strontium, barium and magnesium was determined by capillary electrophoresis. Results: It has been established that potassium, sodium, magnesium and calcium ions were present in all the studied samples, however, their balance is significantly disturbed under conditions of technogenic pollution. It was shown that the frequency of occurrence of lithium, barium, strontium and manganese was significantly higher for СHPP workers compared to the control group. Strontium was not found in the saliva of volunteers in the control group; its appearance correlated with working conditions. Conclusions: The proposed method allows assessing the degree of technogenic load on the body and identifying a risk group for which it is necessary to select appropriate preventive measures and be more attentive to the diagnosis of occupational diseases as part of a planned medical examination.

Water is very important for humans, as it is a solvent for metabolic products. Moreover, it is necessary for metabolism, biochemical and transport processes. The elemental status in persons depends on the geochemical environment and consumption of bioelements with food and water. The aim of the paper is to conduct a comprehensive assessment of chemical composition of drinking tap water in Khanty-Mansiysk and Salekhard. Materials and Methods. The chemical composition of 100 samples of drinking tap water was analyzed by atomic absorption spectrometry, spectrophotometry and capillary electrophoresis. All in all, there were 50 samples from Khanty-Mansiysk and 50 samples from Salekhard. The results were compared with Sanitary Rules and Norms 2.1.4.1074-01. Results. Drinking tap water in Salekhard contains a significantly higher concentration of iron, which is much above the maximum allowable concentration, if compared to water samples in Khanty-Mansiysk (p=0.03). In the cities under consideration, the water undergoes high-quality reagent-free treatment. However, the deterioration of the water supply networks in Salekhard is 3 times as high as in Khanty-Mansiysk. Calcium and magnesium concentration in water samples from Khanty-Mansiysk is 5.6 and 3.9 times lower than the MAC; in water samples from Salekhard calcium concentration is 6.3 (p=0.008) and magnesium concentration 4.6 (p<0.001) times lower than the MAC. Conclusion. The consumption of ultra-fresh drinking water leads to low intake of bioelements, which are a part of enzymes contributing to the human antioxidant defense and can result in manifestation of cardiovascular diseases. This is especially true for Salekhard with very soft drinking water and high iron concentration, which excess can exhibit prooxidant properties. Keywords: tap water, bioelements, northern region, antioxidants. Вода является важнейшим соединением для человека: необходима в качестве растворителя продуктов метаболизма и протекания обменных, биохимических и транспортных процессов. Элементный статус организма человека зависит от геохимического окружения и поступления биоэлементов с пищей и водой. Цель. Провести комплексную оценку химического состава водопроводной воды городов Ханты-Мансийск и Салехард. Материалы и методы. Методами атомно-абсорбционной спектрометрии, спектрофотометрии и капиллярного электрофореза проанализирован химический состав 100 проб водопроводной воды: по 50 из Ханты-Мансийска и Салехарда. Результаты сравнивали с СанПиН 2.1.4.1074-01. Результаты. В водопроводной воде Салехарда установлена превышающая ПДК и достоверно более высокая концентрация железа сравнительно с водой Ханты-Мансийска (р=0,03). При условии качественной безреагентной водоподготовки в изучаемых городах это обусловлено изношенностью водопроводных сетей в Салехарде, более чем в 3 раза превышающей этот показатель в Ханты-Мансийске. Концентрация кальция и магния в воде Ханты-Мансийска в 5,6 и 3,9 раза ниже ПДК; в воде Салехарда – в 6,3 (р=0,008) и 4,6 (р<0,001) раза ниже ПДК соответственно. Заключение. Употребление ультрапресной питьевой воды на фоне очень малого поступления с водой биоэлементов, входящих в состав ферментов антиоксидантной защиты организма человека, может привести к манифестации кардиоваскулярных заболеваний. Это особенно актуально для г. Салехарда с очень мягкой питьевой водой с повышенным содержанием железа, избыток которого может проявлять прооксидантные свойства. Ключевые слова: водопроводная вода, биоэлементы, северный регион, антиоксиданты.

Background: Water is a key source of life on Earth; it is involved in the transfer of nutrients, macro- and microelements between soil, plants, animals and humans, as well as in the concentration and dispersion of chemical elements and the formation of minerals. The elemental status of the population is largely determined by the chemical composition of the natural waters on the territory of residence. Objective: To perform a comparative analysis of the concentrations of iron, manganese, calcium and magnesium in natural waters of the Khanty-Mansiysk and Yamalo-Nenets Autonomous Districts (Okrugs). Materials and methods: We established concentrations of iron, manganese, calcium and magnesium in 100 samples of natural waters taken from rivers, lakes, backwaters, channels, etc. of the Khanty-Mansiysk and Yamalo-Nenets Autonomous Districts, 50 samples each, using spectrophotometry, capillary electrophoresis and atomic absorption spectrometry. The results obtained were compared with the reference values provided in Russian sanitary rules and regulations SanPiN 1.2.3685–21. Results: We established elevated levels of iron in most surface water samples from both districts and of manganese in the Khanty-Mansi Autonomous Okrug accompanied by extremely low concentrations of Ca and Mg in the vast majority of all samples. At the same time, we registered significantly lower concentrations of Ca (p = 0.012) and Mg (p = 0.021) in the water samples from the Yamalo-Nenets Autonomous Okrug compared to those from the other district. Conclusion: In the population of the Tyumen North, the constant use of such water for drinking purposes can lead to the early development and rapid progression of cardiovascular and osteoarticular diseases, type 2 diabetes, neoplasms, etc.; at the same time, people are at risk of generalization of immunosuppressive conditions, diseases of the central nervous system, gastrointestinal tract, oxidative metabolism disorders, etc.
