Aim. Assess the health risk of a cold environment by bioclimatic indices characterizing weather and climatic conditions in the Arctic zone of the Krasnoyarsk Territory.Materials and methods. The mean monthly daily ambient temperature, wind speed and relative air humidity were determined. The body cooling conditions integral index (BCCII) and the wind-cold index (WCI) were calculated.Results and their discussion. Using the BCCII from 4 to 6 months a year at Cape Chelyuskin, the critical risk of frostbite in exposed areas of the body determined at Dixon Island from 4 to 5 months a year; in July and August, the indicator values reached the lower border of the “moderate risk”. Using the WCI, an uncomfortable cold environment was determined, respectively, 2 months and 4 months, a very cold — 3 months and 2 months, and an extremely cold — 3 months and 2 months.Conclusion. The advantage of using BCCII rather than WCI is shown, since on its basis the criteria for safe working conditions in an open area are determined. To interpret the value of “no risk” while using WCI, it is necessary to know the period of the year, in which the weather and climatic conditions are assessed as a cold environment.

In recent years, significant efforts have been made to accelerate the economic development of the Arctic zone, leading to intense environmental pollution of this region, accompanied by the significant impact of accumulated environmental damage in the region. The solution to these problems is difficult due to the remoteness of these areas and severe climatic conditions. Therefore, it is important to evaluate the potential for restoration of arctic soils. For this purpose, various indicators are used, including biological ones. In the analyzed arctic soil samples, high concentrations of petroleum hydrocarbons (up to 47,000 mg/kg) and chloride-ions (0.10–0.14 wt %) were established. Microbioassay demonstrated a presence of hydrocarbon-oxidizing microorganisms: Penicillium, Azotobacter chroococcum, Bacillus subtilis, Pseudomonas oleovorans. A low enzymatic activity and specific Arctic climate point out a low self-restoration ability of the soil, demonstrated the need for its remediation. The microbioassay with microbial strains identification and soil remediation methods suitable for the Arctic zone were recommended.

This article presents the sexual characteristics of cerebral energy metabolism in young residents of the Arctic zone according to the distribution of the level of direct constant potential (DC-potential level) of the brain. The study involved 60 people (27 men and 33 women) aged 30-34 years, born and living in the Arctic territory. Assessment of cerebral energy exchange was carried out using a 5-channel hardware-software diagnostic complex «NeuroKM». The distribution of the DC-potential level was analyzed by mapping monopolar values and calculating their gradients. For statistical data processing, the SPSS Statistics26 software package was used. The obtained DC-potentials level results were compared with the average statistical standard values. As a result of the study, gender differences in cerebral energy exchange were revealed in working-age residents born and living in the Arctic zone, depending on gender. In the group of men, there is a higher intensity of cerebral energy exchange in the whole cerebral cortex, the absence of pronounced hemispheric dominance, activation of the central and frontal cortex. In women, there is no predominance of energy exchange in any one area, there are low total indicators, activation of the central and occipital regions of the cortex; connection of the central cortex with the temporal, right-hemisphere dominance of cerebral energy exchange processes. Conclusion. Men are characterized by centralization and tension of regulatory systems, which can be an unfavorable factor in ensuring long-term adaptation to the climatic conditions of the Arctic. Women have a more optimal level of cerebral energy exchange.

This paper analyses environmental factors and their influence on the human body in the Far North. The cold factor is considered separately. It is noted that adaptation to extreme environmental factors in the north resembles adaptive processes taking place in the body under stress. The article describes the phenotypic approach to preventing non-communicable diseases in the population based on the theory of adaptation, control theory, theory of functional systems and system approach. We suggest using a predictive model of the body in the form of an anatomico-physiological structure reflecting grouping of interacting organs and tissues by their physiological functions. The model is represented by the reaction norms of the body’s systems and by the rules of their interaction. With its help, one can identify the predisposition of the body’s systems to destruction and the corresponding cause-and-effect relationships in the body, as well as devise a personal algorithm for health preservation and carry out vocational selection. The predictive properties of the model are based on the manifestations of the adaptive response to environmental stress factors. The recommendations are preventive in nature and are aimed at stimulating the individual’s involvement in his/her health protection. Methods of influencing the homeostatic regulation of the body and increasing the capabilities of the immune system in the north are proposed, i.e. technologies for restoring the body’s circadian rhythm as well as activating the living environment and drinking water in order to prevent chronic non-infectious diseases. The suggested predictive model of the body contributes to the development of a general theory of adaptation and a general theory of pathology. The considered approach to health preservation is compatible with telemedicine and e-health technologies and can therefore make adequate medical services available to the population of the Far North, in particular to those living in remote areas.

The aim of the study is to assess the micronutrient status in the autumn and winter periods of conscripted military personnel serving in the Arctic zone of the Russian Federation (Arctic); to perform a comparative analysis of the laboratory and clinical methods used to determine micronutrient insufficiency. Materials and methods of research. The study involved 154 conscripts (all male) aged 18-25 years, healthy, service experience in the Arctic – from 4 months. In the autumn (2 points) and spring (one point) phases the following issues were studied: a set of physical health indicators; laboratory indicators of 8 vitamins (A, E, D, C, B1, B2, B12, folic acid) and 8 minerals (Fe, Ca, P, Co, Mn, Cu, Se, Cr) in the blood; symptoms of vitamin deficiency. The state of health, physical fitness, morbidity and hospitalization of the subjects were evaluated. Research results and their analysis. Data were obtained on the prevalence of hidden (subclinical) forms of vitamin deficiency, including more than 50% – for folic acid, vitamins A, E, D, C, as well as all the studied minerals - in the autumn-winter period, which is more dangerous in terms of the incidence of respiratory infections in organized contingents. The classical view of the prevalence of hypovitaminosis in the spring was revised, which was only partially confirmed for vitamins C and B1. It was found that the classical methods of diagnosis based on clinical symptoms used to determine manifest forms of hypo-and avitaminosis are ineffective for early detection of subclinical forms (prehypovitaminosis). The necessity is substantiated of wider implementation of modern means of laboratory diagnostics of micronutrient deficiency in the body using a proven method of freezing transported samples in combination with already used hygienic methods.

Methodological base was developed for assessing the quality of firefighter - saviour combat clothing for use in the Arctic zone. It consists of a mathematical model for calculating the thermal state of special combat clothing in the «man — firefighter’s combat clothing — working environment» system and a chamber climate test methodology with the participation of testers-volunteers. The results of some calculations of the firefighter’s combat clothing thermodynamic state under the climatic factors exposure (negative values of the ambient temperature, wind load), and the fire thermal factors exposure are presented. Calculations were made based on the time and tasks performed, on the basis of actual working conditions of the firefighter. According to the calculation results we can conclude that in the considered range of variation of the environmental parameters of the working environment in the climatic conditions of the Arctic zone, the time of protective action of a multilayer stack of materials and tissues of the firefighter’s combat clothing is determined by the time of reaching of the skin surface limit temperature cooling in the region of the unheated structural elements. In this case the heat flux is not a determining factor. Verification of the model is carried out by comparing the results of experimental measurements and data obtained by calculation. The climate chamber test methodology includes registration in the process of tests of the firefighter’s combat clothing under-suit space thermodynamic parameters and the tester physiological parameters using both special sensors and displaying the results on a computer multiplier in real time mode. In addition, a visual assessment of the firefighter’s combat clothing technical condition at the end of the tests is carried out. Based on the results of the performed studies of the specific firefighter’s combat clothing samples it can be concluded that the developed methodological base allows to perform the objective assessment of the Arctic version of the firefighter’s combat clothing according to the application indicators that determine the quality of the product, and can be used to assess the quality of other personal protective equipment of a firefighter.

Increasing the pace of development of the Arctic zone, among other tasks, requires the attraction of significant production resources to improve the transport network, in particular, road construction equipment and technological equipment. Extreme climatic conditions, including low air temperatures and strong winds, are features of the Arctic zone. In this regard, there is a need to form a methodological basis for the development of construction and repair materials for use in the Arctic. To solve this problem, based on the results of mechanical tests at temperatures of +20°C, -30°C and -50°C, the possibility of using carbon fiber plastics with various types of hybrid matrices for the manufacture of mechanical engineering products operating in extreme conditions of the Arctic and the creation of reinforcing linings during their repair. The indicators of manufacturability during repairs under the conditions of constant exposure to negative temperatures using polymeric materials are considered.
