By methods of atom-emission and mass spectrometry with inductively bonded argon plasma there was determined the content of 25 macro- and trace elements in tap cold drinking water used by the residents of the city of Magadan for food purposes and in hair samples of 30 young male Europeans aged of 17-23 years, who are the residents of the city of Magadan. According to our data the content of 25 elements in drinking water conforms to standards, but that content of such essential elements as Co, Cr, Cu, I, Mn, Na, Se, Zn is shown to be lower than referential indices. After boiling the water the concentration of trace elements is changed. The content of Cd, Cu, K, P, Pb, Zn, Ni becomes lower significantly. In healthy young men aged of 17-23 years, from the number of natives Europeoids, residents of the North there was detected deficit of Co and I (86% and 62%, respectively), lower concentrations of Ca, Mg, Se, Zn (76%, 69%, 24%, 24%, respectively). The constant use by residents of the city of Magadan of ultrafresh brackish drinking water in food aims may be the one of the main reasons of the imbalance of macro- and micronutrients in the body, characterized by features of the so-called "northern" type with a marked deficiency of basic essential elements.

To determine age-relatedpeculiarities of trace element system in oldpeople, residing in different natural and geographical regions, the content of 25 trace elements in hair samples of women from Arkhangelsk (average age is 87,0±0,98 years) and Magadan (average age is 80,1±1,25 years) was determined by spectrometric methods. In both groups there was established element misbalance characterized by lower concentration of such essential elements as Ca, Mg, Co, Cu and higher concentration of Na. The excess of K and Zn is more expressed in hair of female residents of Arkhangelsk in comparison with the city of Magadan there was revealed significantly more higher content of aluminum, boron, silicon, in the city of Magadan there are significantly higher concentrations of selenium and tin. According to the frequency of occurrence the excess of elements in the body of residents of the city of Arkhangelsk is comparable to that of residents of the city of Magadan, but has its own features. In Arkhangelsk there is more pronounced the excess ofpotassium, there was found high content of zinc, whereas in the city of Magadan there was revealed an excess of manganese and arsenic. Square of the figure, reflecting the deficiency of elements in female residents of the city of Magadan is more than in the city of Arkhangelsk, which is manifested by larger deficiency of chromium, zinc, iron. Identified regional differences in the content of macro- and microelements are related to biogeochemical and ecological features of the regions, which can determine the specifics of the aging diseases and time of their occurrence.

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.

The heat of the earth is provided by solar radiation. A change in the angle of solar radiation and the surface of the earth causes changes in the ambient temperature. Sometimes, these changes reduce climatic comfort of human beings. Climatic comfort is established when there is a balance between excreted and absorbed temperatures of the skin of the body. Orientation and extension rates of physics of squares relative to the geographical north influence the amount of received direct sunlight in different months. Relevant studies show that the squares of the city of Yazd reduce the climatic comfort of its citizens; moreover, the physics of Yazd's squares apply various extension rates, which led to high building costs to citizens and relevant organizations. This study, by using the correlation method and R software, measures different orientation and extension rates of physics of squares in Yazd. It analyzes two models with orientation and physical extension as variables and evaluates the shade and sunlight in the space. The results reveal significant differences between desirable and undesirable options. Considering the climatic comfort of space users and residents at the same time, a rectangle with an extension ratio of one to several and the north-south orientation, making the lowest facade face the south, is the most appropriate physic for city squares.

Control of the trace element content in tap water is particularly important for large industrial regions. The estimation of Cd, Pb, Cu, As, Ni, Zn, Mn, Hg, Se and Co concentration in the tap water of Kryvyi Rih city (Karachuny Reservoir) was accomplished using electrochemical methods, the most popular methods for determining the content of trace elements in natural objects and tap water. A simple and rapid method to determine trace elements in the tap water (Kryvyi Rih city) by inversion-voltammetry has been used. The concentration of trace elements was measured by voltammetricanalyzer AVA-2 device that implements the method of inversion voltammetry on a solid rotating electrode made of carbon material. The monitoring of the trace element content in the water of the Karachuny reservoir was carried out on a monthly basis between September 2018 and August 2019. The article presents the obtained voltamperograms of some trace elements, describes content of the trace element in tap water during the year (12 data for each trace element) and analyzes the compliance of drinking water in the city of Kryvyi Rih to the standards and normative indicators of drinking water quality.

AbstractThis article examines the historical formation of local masculine identity in the city of Dalian in north-east China. I argue that the experiences of Dalian-Chinese men under Japanese colonialism (1905–45) established a model of masculine identity based on bodily resistance. The article explores Dalian men's encounter with colonialism by comparing two different forms of bodily experience: military calisthenics in Japanese-run schools for Chinese boys and street soccer. On the one hand, military calisthenics impressed Chinese schoolboys with a sense of subjugation focused on the body. Bodily movements were performed under the strict scrutiny of Japanese drill masters and formed an integral part of everyday rituals of obedience. On the other hand, street soccer emerged as a popular and potentially creative activity among Chinese schoolboys. In contrast with the controlled motions of military calisthenics, soccer offered a sense of freedom in its unrestricted and improvised movements. Matches against Japanese teams even more explicitly infused soccer with a spirit of nationalistic resistance. In conclusion, I argue that these bodily experiences are crucial to understanding the historical reformations of Dalian male gender identity.

The main challenges leading to the decrease of bone mineral metabolism in the conditions of the North are covered. The presented results of a study of 29 soldiers serving in the extreme conditions of the North, to study the mineral density of bone tissue in the distal forearm. Revealed a significant decrease in bone mineral density, as well as a deficiency of essential elements in this cohort. So, when densitometric training of servicemen serving in the North, the average Z-test was 0±1,8 SD, the change in bone mass corresponded to the Z-test less than -2 SD, was determined at 31,03%. Vitamin D3 deficiency was detected in 96,5% of cases. Analysis of the bio-element state of the hair revealed a deviation of the reference interval in 100% of military personnel, a decrease in essential elements: cobalt, selenium, magnesium, vanadium and an increase in the level of barium, bromine, arsenic, as well as caesium. The interrelation of the elemental status and bone mineral density is revealed. 100% of the examined hair samples showed a significant decrease in the level of cobalt, selenium and iodine. (p0,05) a decrease in boron, magnesium, calcium, vanadium (p0,05) and a significant increase in chromium, manganese, and copper. A quantitative study of toxic elements revealed a significant (p0,05) increase in mercury, rubidium, strontium, and caesium. A correlation was established between the Z-test and the level of vitamin D3, body mass index and dynamometer. The data obtained determine the required level of trace elements in order to prevent disturbances of mineral metabolism and bone loss.

Abstract Based on the high prevalence, diabetes mellitus (DM) is considered as a worldwide problem. More than 8.3 % of the world population is suffering from this disease. One of the causing factors of this disease can be the absence or imbalance of trace, essential elements. It can cause collapses of antioxidant defence and glucose intolerance. It plays a role in the pathogenesis and progression to diabetes mellitus. This review focuses on chromium, copper, selenium, vanadium, and zinc. Many studies deal with these elements but there is variability in opinions. Insulin-mimetic activity and ability to control the concentrations of blood glucose were confirmed. However, these effects were of more importance in patients with prediabetes. In patients with prediabetes, due to the supplementation of selected trace elements, it is possible to normalize the blood glucose level and prevent the development of diabetes mellitus. The importance of supplementation was confirmed for chromium and zinc. The supplementation of vanadium has a positive effect on the normalization of glycaemia but it is necessary to control the level as it can have toxic effects during long-term treatment. Conversely, higher copper concentrations in the body adversely affect patients and chelation therapy is needed. Selenium must be kept in the standard concentration and regular control of the concentration in the body is necessary. For this reason it is necessary to continue with analysis and the creation of new methodologies that could unify the view on the issue.

Significance. According to WHO, unbalanced diet is one of the leading causes of chronic diseases. Adolescence should be considered a person’s life most important period in terms of developing eating habits that define the body macro- and micronutrient intake. The purpose of the study was to assess diet type and balance and specify region-related macro- and micronutrient diet profiles among young Caucasian and Aborigine males in the North-East of Russia. Material and method. ASPON-nutrition software program was used to analyze the availability of proteins, fats, carbohydrates, fiber, vitamins, as well as macro- and microelements in diets of young males residing in the Magadan Region and Chukotka Autonomous District (mean age equals to 17-21 years, n = 278). Results. The study has identified a clear imbalance in the diet characterized by a low intake of the protein-lipid component, a shortage of polyunsaturated fatty acids, and a complete lack of fiber intake against the background of the increased share of mono- and disaccharides as well a deficiency of macro-, microelements and vitamins in the diet. The deviations have proved to be typical of people residing in the city of Magadan, primarily of the young indigenous population who experience a 100 percent nutritional deficit for a number of components.

Mercury and lead are not essential elements and have a high degree of toxicity to all groups of living organisms, including hydrobionts. In turn, the accumulation of dangerous chemical elements in the primary trophic units of marine ecosystems is also reflected in the high level of accumulation and toxication of fish-valuable objects of fishing. As part of the study of the ecological state of the biota of the Volga-Caspian basin, there is a need to study the concentrations of heavy metals such as mercury and lead. The aim of the work is to study the content of mercury and lead in some invertebrate species of the Caspian Sea. The main source of mercury and lead in the body of the studied species is the water of the north-western part of the Caspian Sea. Among the studied taxonomic groups of organisms, mercury accumulators were all species of mollusks, as well as Balanus improvises and Rhithropanopeus harrisii. The lead concentrating organisms were Cerastoderma lamarcki and Mytilaster lineatus, Rhithropanopeus harrisii, and Balanus improvises.

Human body requires certain essential elements in small quantities and their absence or excess may result in severe malfunctioning of the body and even death in extreme cases because these essential trace elements directly influence the metabolic and physiologic processes of the organism. Rapid urbanization and economic development have resulted in drastic changes in diets with developing preference towards refined diet and nutritionally deprived junk food. Poor nutrition can lead to reduced immunity, augmented vulnerability to various oral and systemic diseases, impaired physical and mental growth, and reduced efficiency. Diet and nutrition affect oral health in a variety of ways with influence on craniofacial development and growth and maintenance of dental and oral soft tissues. Oral potentially malignant disorders (OPMD) are treated with antioxidants containing essential trace elements like selenium but even increased dietary intake of trace elements like copper could lead to oral submucous fibrosis. The deficiency or excess of other trace elements like iodine, iron, zinc, and so forth has a profound effect on the body and such conditions are often diagnosed through their early oral manifestations. This review appraises the biological functions of significant trace elements and their role in preservation of oral health and progression of various oral diseases.
