Vitamin D and childhood disability: diseases of the nervous system

Child disability associated with diseases of the nervous system, the main cause of which is cerebral palsy (CP), is often accompanied by an insufficient level and high prevalence of vitamin D deficiency, but in our opinion, practicing physicians and health officials at all levels pay insufficient attention to this problem, therefore, this paper is devoted to the study of the influence of vitamin D on the disability of children resulting from diseases of the nervous system. We statistically investigated the association between the prevalence of vitamin D deficiency in municipalities of Khanty-Mansiysk Autonomous Okrug — Yugra and the number of cases of resulting childhood disability due to nervous system disease in 2021, using the anonymized results of 31,596 measurements of vitamin D levels in residents of the autonomous okrug, gratuitously provided to us by INVITRO-Ural LLC, whose staff the authors express their deep gratitude to. The calculations demonstrated the presence of a directly proportional relationship between the incidence of disability as a result of nervous system disease and the prevalence of severe vitamin D deficiency in the territory of Khanty-Mansi Autonomous Okrug — Yugra. The incidence of cerebral palsy is largely due to pregnancy abnormalities. Many researchers have associated the occurrence of cerebral palsy with preterm labor and low birth weight of the newborn with normal gestational age. The analysis indicates the great influence of vitamin D on the course and results of pregnancy, since pregnant women often have insufficient levels of vitamin D, which does not ensure full development of the fetus, which is accompanied by an increased incidence of various pathologies in the mother and child. Taking vitamin D supplements as prescribed by a doctor can be useful for pregnant women and children with cerebral palsy. The former need it to ensure the normal course and favorable outcome of pregnancy, and the latter — to increase bone mineral density and improve the body’s immune defense against a variety of diseases. To make recommendations on the amount of daily dosage and duration of vitamin D preparations, accurate knowledge of its initial level in the patient’s blood serum is required, which predetermines the need for mandatory monitoring of 25(OH)D levels in pregnant women and patients with cerebral palsy.

Стратегические вызовы и возможности развития туризма малых городов России

The article analyzes the peculiarities and prospects of tourism development in small towns of Khanty-Mansiysk Autonomous Okrug – Yugra (KhMAO – Yugra), in particular the city of Langepas. The purpose of the work was to study the peculiarities and prospects of development of the tourism industry of the city of Langepas, which in accordance with the Strategy of socio-economic development of Khanty-Mansi Autonomous Okrug – Yugra until 2036 with target benchmarks up to 2050, as well as the Concept of development of tourist areas of Khanty-Mansi Autonomous Okrug – Yugra is included in the tourist territory of Nizhnevartovsk – Nizhnevartovsk municipal district – Megion – Langepas. In this regard, the development of tourism in the city of Langepas is inextricably linked with the tourist characteristics of the Nizhnevartovsk municipal district. The key feature of the tourist territory of Nizhnevartovsk – Nizhnevartovsk Municipal District – Megion – Langepas is its industrial character, the main part of exploited oil fields is located here. The main objects of the social framework of the city of Langepas are: architectural ensembles, monuments of architecture, sculptural compositions, social and cultural facilities: museums, cultural centers, sports facilities. In the course of studying the official sites of the city, regulatory and legal framework in the field of tourism development, statistical information on the subject of the study, the key problems, features, “points of growth” and prospects for the development of the tourist complex of the city were identified. Based on the analysis, the author concludes that in the course of creating an effective system for promoting the city’s tourism product, it is necessary to focus on three components: brand strategy, management of tourism product promotion, and provision of financial resources for its implementation. According to the results of the proposed measures, the number of tourists accommodated in collective accommodation facilities of the city should reach 5.6 thousand people by the end of 2030.

Effects of vitamin D on the incidence and severity of COVID-19

In the fall of 2023, infection of a number of European countries population with coronavirus intensified, with the most noticeable increase in incidence observed in the Russian Federation. Patients infected with SARS-CoV-2 usually have a low level and high prevalence of vitamin D deficiency. Data from measurements of vitamin D levels in the municipalities of the Khanty-Mansiysk autonomous Okrug — Ugra, compared with information from the department of health of the autonomous okrug based on the results of 2021, suggest that in the Khanty-Mansi autonomous Okrug — Ugra, the average duration of one case of disability due to illness with a diagnosis of COVID-19 is directly proportional to the prevalence of severe vitamin D deficiency. Our data characterizing the positive effect of a high level of vitamin D in the blood serum of a patient infected SARS-CoV-2, on the body’s ability to recover, is confirmed in foreign clinical practice, as evidenced by the results of our statistical calculations. In the Russian Federation, the dependence of the overall incidence of COVID-19 is directly proportional to the geographical latitude of the territory, and the relationship b etween the parameters is extremely high (p = 0.0008 in 2021 and p < 0.000001 in 2022), which, along with other reasons, suggests the effect of ultraviolet radiation level decrease. Vitamin D levels are one of the key factors in the incidence of COVID-19, as it has a major impact on its duration, more severe lung damage, and higher mortality in patients infected with SARS-CoV-2. Clinical studies by domestic and foreign scientists have shown that severe vitamin D deficiency [25(OH)D < 10 ng/ml] in patients infected with SARS-CoV-2 can be considered a predictor of death. During the COVID-19 pandemic, enormous positive experience has been gained in the use of vitamin D as a therapeutic agent to reduce the severity of the disease and the level of hospital mortality, however, in order to prepare informed recommendations for taking medications and identify severe vitamin D deficiency, mandatory measurement of 25(OH)D levels in patients is required in patients diagnosed with SARS-CoV-2 infection.

Biotesting for adsorptive bioremediation of oil-contaminated podzolic soil in Western Siberia

The majority of Russia’s oil and gas-producing regions are situated in the northern part of Western Siberia, where sandy podzolic soils are prevalent. Due to the low buffering capacity of these soils and the severe Arctic climate, the conventional method of bioremediation for removing oil contamination is not effective. This study, for the first time, explores the potential of adsorptive bioremediation for purifying oil-polluted gley-podzolic soil. This approach involves introducing natural sorbents of various classes before soil treatment through bioremediation. The optimal conditions for soil treatment can be determined using the express phytotests based on white clover ( Trifolium repens ) seed germination. The results indicate that under the best conditions, which involve adding 2 % mixed sorbent based on granulated activated carbon (GAC) and diatomite (4:1) or Spilsorb, it is possible to minimize soil phytotoxicity after 2-3 warm seasons and reduce the content of total petroleum hydrocarbons to the permissible residual oil content (≤5 g/kg) established in the territory of the Khanty-Mansiysk Autonomous Okrug for recultivated agricultural soils. Moreover, other sorbents, such as peat, GAC, vermiculite, zeolite, and diatomite, can be used to reduce phytotoxicity to <33 %, allowing for additional soil decontamination through phytoremediation.

On the issue of assessing the importance of associated petroleum gas as a valuable raw material in the fields of the Khanty-Mansiysk Autonomous Okrug

the purpose of this article is to consider the problem of flaring associated petroleum gas (APG), as one of the most relevant and acute for our country, because Russia occupies a leading position in the world in terms of APG flaring volumes. Burning APG leads to environmental damage, contributes to the greenhouse effect, harms public health, as well as the country's economy - valuable chemical raw materials and energy resources are simply thrown away. According to the Ministry of Natural Resources of the Russian Federation, out of 55 billion m3 of APG produced annually in Russia, only 26% (14 billion m3) is sent for processing, 47% (26 billion m3) goes to the needs of the fields, or is written off as technological losses and 27 % (15 billion m3) is flared.

Construction of water objects for comprehensive filtration gabion treatment

The processes of oil production and its further transportation are accompanied by the discharge of large amounts of waste contaminated water into reservoirs, which pollutes the environment, increases the acidity of water resources, kills the ecosystem of reservoirs, and the process of waterlogging occurs. The purpose of the study is to study methods for purifying water bodies from pollution using gabion filtration purification of water bodies. The authors hypothesize that gabion treatment filtration structures can be used to successfully clean water bodies of contaminants and impurities. The research methods were the study of scientific literature and scientific research in the field of sanitary treatment of the aquatic natural environment, based on the experience learned, the creation of an experimental model of gabion structures. Based on the results of tests of gabion structures in the Khanty-Mansiysk Autonomous Okrug of Yugra, it was experimentally proven that wastewater is effectively purified from impurities of artificial and natural origin through gabion treatment filtration structures.

Association of <i>CSK, MTHFR, ACE, ADRA2B, TCF7L2</i> gene polymorphisms with dyslipidemia among indigenous and non-indigenous people of Khanty-Mansy Autonomous Okrug – Yugra

The increase in cardiovascular diseases and their complications, diabetes mellitus and metabolic syndrome determines the relevance of early diagnosis and prevention of lipid metabolism disorders by identifying and studying genetic markers of predisposition to dyslipidemia in various populations depending on gender, age and ethnicity.Aim of the study was to investigate the associations of candidate genes CSK, MTHFR, ACE, ADRA2B and TCF7L2 with dyslipidemia in the young indigenous and non-indigenous population living in the Khanty-Mansy autonomous Okrug – Ugra.Material and methods. 863 young people aged 18–44 years were examined, clinical population included nonindigenous and indigenous men and women with metabolic syndrome (n = 344), the comparison group included non-indigenous and indigenous men and women without metabolic syndrome (n = 519). A study of the lipid profile and molecular genetic study was carried out using the polymerase chain reaction method for single nucleotide polymorphisms (SNPs): rs1378942 of the gene CSK, rs1801133 (C677T) of the gene MTHFR, gene ADRA2B, rs7903146 of the gene TCF7L2, rs1799752 of the gene ACE.Results. A high frequency of hypercholesterolemia (79.0 %) and hypertriglyceridemia (65.8 %) was found in the examined men and women. Statistically significant differences were established in the frequency of dyslipidemia in patients with metabolic syndrome by ethnicity and gender (p < 0.001). In the general cohort of men with metabolic syndrome hypercholesterolemia is associated with the TT genotype of SNP rs1801133 (C677T) of the gene MTHFR (p = 0.039), in the women – with the DD genotype of the gene ADRA2B (p = 0.010). In indigenous men of the clinical group an association of hypercholesterolemia with the minor T allele of the gene MTHFR (p = 0.005), of hypertriglyceridemia – with the minor T allele of the gene MTHFR (p = 0.031) and the T allele of the gene TCF7L2 (p = 0.031) was revealed. Among indigenous women of the clinical group hypercholesterolemia is associated with carriage of the minor T allele of the gene CSK (p < 0.001) and hypertriglyceridemia – with the D allele of the gene ADRA2B (p = 0.046).Conclusions. Carriage of minor alleles T of the MTHFR gene and D of the ADRA2B gene is associated with hypercholesterolemia among the examined young people and is statistically significantly higher in the group of patients with metabolic syndrome, as well as among indigenous residents of the KhantyMansiysk Autonomous Okrug – Ugra.

Качество жизни населения в условиях цифровизации: институциональные и инфраструктурные аспекты

The authors of the article note that digitalization is a global trend of technological transformation, which affects not only the production sector, but also society as a whole and each individual. Currently, the scientific base of digital processes is being formed both in the industrial sphere (Industry 4.0) and in almost all spheres of society (Society 5.0). Strengthening the digitalization of the economy and society is aimed at achieving a new, higher quality of life for the population. The purpose of the study is to analyze the institutional and infrastructural conditions for the digitalization of social space in the Russian Federation and regions, and to highlight the best regional practices. To carry out the work, official statistical data from the state statistics website Rosstat were used. Main research methods: review and content analysis of scientific works in this area, collection and processing of statistical information, interregional comparisons according to selected criteria. The study analyzed the conditions for the development of digitalization of the social space of the regions. From the ranking of regions by level of digitalization, a research site was selected: among the leaders are cities of federal status - Moscow and St. Petersburg, as well as regions of the Russian Federation - Khanty-Mansiysk Autonomous Okrug and Yamalo-Nenets Autonomous Okrug; Among the outsiders are the Republic of Ingushetia and the Jewish Autonomous Region. An analysis was carried out of the availability and frequency of use of information and communication technologies by the population of the regions. The issues of institutional and infrastructural digital provision of the quality of life of the regional population are considered. In conclusion, an analysis of best practices was carried out, which made it possible to systematize promising areas of digitalization of the social sphere in the regions of the Russian Federation.

CORPORATE SOCIAL RESPONSIBILITY OF BUSINESS AS A TOOL FOR THE FORMATION OF THE BRAND OF THE NORTHERN TERRITORY FOR THE INTERNAL TARGET AUDIENCE

The article considers the communicative potential of corporate social responsibility of subsoil user companies in the northern territories of Russia as a tool for the formation of a territorial brand for the internal target audience living in northern settlements with an unfavorable climate. The purpose of the study is to determine the formation of the KhMAO brand for residents of this territory and the role of corporate social responsibility of subsoil user companies in this process. From the authors’ point of view, the presence of a strong brand of the northern territory, in addition to the population’s knowledge of its heraldic symbols and emotional attachment to the place of residence, is expressed in a high degree of involvement of residents in public life and the desire to continue living in this territory.The study was conducted in October-December 2022 by an online survey, which was attended by residents of the Khanty-Mansiysk Autonomous Okrug - Yugra: large cities and small settlements (n=287).The results of the study show that the KhMAO can be considered as a brand: its residents highlight the unique qualities of the place of residence, about half give it a positive assessment, most know heraldic symbols, about a third plan to continue living in this territory. The study also revealed that knowledge of CSR programs implemented by subsoil user companies and their assessment as eff ective is higher among those residents of the territory who plan to continue living in this territory. This is especially noticeable on the example of the rural settlement of Salym, the data for which were analyzed separately. This approach to the analysis was chosen because a number of large projects are being implemented in the territory of this settlement within the framework of corporate social responsibility by the oil company Salym Petroleum Development.The results of the study allowed us to conclude about the eff ectiveness of corporate social responsibility as a tool for building and strengthening the brand of the northern territory for the internal target audience, to identify the most promising areas of this activity and to show the importance of its information support

Intersystem interactions of physiological system indicators in students with different types of autonomic regulation

Studying not only individual students indicators of students, but complex intersystem interactions that reflect the specifics of adaptive capabilities is of scientific interest. The aim of the study. To reveal the features of intersystem interactions of indicators of the blood vessels functional state, morphological and neurodynamic characteristics of students with different types of autonomic regulation, living in the KhantyMansiysk Autonomous Okrug – Yugra. Methods. 429 first–fourth-year students (348 girls, 80 boys) of the Surgut State Pedagogical University were examined. The initial type of autonomic regulation was determined by the average duration of electrocardiogram RR intervals. Anthropometry parameters (body length and weight) and body composition were assessed using Tanita BC-601 device (Tanita, Japan), vascular wall elasticity – using AngioScan-01 (AngioScan-Electronics Ltd, Russia), neurodynamic indicators – using NS-PsychoTest device (Neurosoft, Russia). Statistical analysis was carried out using Statistica 7.0 software (StatSoft Inc., USA). We used the nonparametric Mann – Whitney U-test to evaluate differences and the nonparametric Pearson R-test to analyze correlations. Results. An increase in the stiffness of the vascular wall of large and small arteries in girls is accompanied by an increase in parasympathetic activity. In young men, an increase in the stiffness of large arteries raises with an increase in sympathoadrenal activity, while a compensatory increase in the stiffness of small muscular arteries is noted with an increase in parasympathetic activity. In persons with the sympathicotonic type of autonomic regulation, an excess content of fat mass, an increased frequency of visceral obesity, and a deficiency in water content were registered. With the predominance of the parasympathetic component contribution to the regulation of cardiac rhythm, an increase in the processes of inhibition in the central nervous system was noted. In young men, reduced sensorimotor reactions are consistent with sympathetic activation in the regulation of heart rate. Correlation analysis made it possible to establish some features in the interaction of the vascular, morphological and central nervous systems. Conclusion. Differences in indicators of functional systems (physical development, blood flow, neurodynamic characteristics) in the examined groups of students are shown, taking into account gender and autonomic regulation type. Features of intersystem interactions of indicators of physiological systems of students’ bodies with different types of autonomic regulation were revealed.

Effect of dihydroquercetin on oxidative metabolism in young athletes engaged in winter sports in a northern region

AIM: To study the effect of dihydroquercetin on the indicators of oxidative metabolism in young athletes engaged in the winter sports in the Khanty-Mansiysk Autonomous Okrug (KhMAO).
 MATERIAL AND METHODS: The indicators of oxidative metabolism were studied in a group of 56 male students (mean age 19.300.51 years) from the Khanty-Mansiysk boarding school of the Olympic reserve. These students were actively involved in winter sports such as cross-country skiing and biathlon. To assess the impact of the plant-derived antioxidant bioflavonoid Baikal dihydroquercetin (DHQ), the participants were administered a daily dose of 120 mg of DHQ for a period of 60 days. Measurements were taken before and after the exposure. Blood lipid peroxidation (LPO) products were studied, namely, lipid hydroperoxides (LHP) and products that react with 2-thiobarbituric acid products (PR-TBA). Additionally, we examined the indicators of the body's antioxidant defense system (ADS) through the assessment of total antioxidant activity (TAA) and thiol status (TS). To quantify the overall oxidative stress experienced by the participants, we calculated the oxidative stress coefficient (OSC) using the formula: OSC = LHP PR-TBA / TAA TS.
 RESULTS: The average levels of LPO values (HPL and PR-TBA) among KhMAO athletes have surpassed the upper limit of optimal values. On the other hand, the ADS parameters (TAA and TS) fall within the range of physiologically optimal values, albeit closer to the lower limit. Notably, athletes have exhibited an OSC increase that is nearly 3.5 times higher than the maximum allowable value. A quarter of the individuals examined displayed elevated HPL values, while more than 30% showed increased PR-TBA levels. A third of male athletes exhibited reduced ADS values compared to the physiologically optimal range. In total, 70.4% of skiers and biathletes in KhMAO have exceeded the OSC parameters. After two months of daily intake of 120 mg DHQ, the normalization of indicators of oxidative metabolism was observed. All parameters aligned with physiologically optimal values, except for OSC. We found a decrease in primary (LHP, 1.15 times) and secondary (PR-TBA, p=0.046) LPO indicators parallel to a significant increase in ADS indicators, specifically TAA (p=0.022) and TS (p=0.049). Conversely, there was a significant increase in ADS indicators, specifically TAA (p=0.022) and TS (p=0.049).
 Despite these positive changes, the OSC value, although significantly reduced (p 0.001) by 2.3 times compared to the initial value, remained above the upper limit of the physiological norm.
 CONCLUSION: The study demonstrated that young athletes engaged in winter sports experienced improved indicators of oxidative metabolism after a consistent two-month intake of the potent antioxidant DHQ. This led to the restoration of a balanced prooxidant-antioxidant state, enhanced overall well-being, and expedited recovery following intense physical exertion. Furthermore, our results may suggest that DHQ may contribute to prevention of non-communicable diseases in the future.

Common Glow-Worm <i>Lampyris noctiluca</i> (Coleoptera, Lampyridae) in the Khanty-Mansiysk Autonomous Okrug – Ugra

The distribution of common glow-worm Lampyris noctiluca (Linnaeus, 1767) in Western Siberia is not thoroughly studied. The report presents the data on findings of this species in the Khanty-Mansiysk Autonomous Okrug Ugra. All registrations of beetles known to us were made in the western part of the okrug (Sovetskiy and Kondinskiy districts) in Malaya Sosva Nature Reserve in the area of the city of Sovetskiy, the villages of Yagodnyy, Listvenichnyy, Mezhdurechenskiy (survey data) and Staryy Katysh. Most likely, the outermost part of the area of common glow-worm with the northern border near Malaya Sosva Nature Reserve is located in the denoted region. The explored species absent on the significant area to the east probably due to the severe bogging of the region in this part. To the north, in addition to the biotopic component, other unfavorable environmental factors may have a limiting effect: weather elements and illumination. Limitative influence of human economic activity is not excluded in the habitats of insects. As a rare, not thoroughly explored and sporadically distributed species, common glow-worm can be included in the regional Red Data Book.

Features of the etiological structure of non-polio enterovirus infection in children in the pre-pandemic and post-pandemic periods

BACKGROUND: Regional features of the etiological structure of nonpolio enterovirus infection (NPEVI) in children in the pre- and post-pandemic periods must be registered.
 AIM: To determine the features of the etiological structure of NPEVI in children in the pre- and post-pandemic periods in the KhantyMansiysk Autonomous Okrug.
 MATERIALS AND METHODS: Statistical observation data for 20132022 and results of molecular genetic studies of the structure of NPEVI in children in the pre- and post-pandemic periods were analyzed.
 RESULTS: The tendency of the incidence of NPEVI in the KhantyMansiysk Autonomous Okrug to increase in the pre-COVID-19 pandemic and a predominance of children aged 6 years has been established. In the study period up to 2019 (pre-pandemic), enteroviruses Coxsackie A6 in combination with E A71 were dominant, for which the calculated trends of the short-term forecast were confirmed in 2022. In the same year, these enteroviruses were the most common causes of focal diseases with exanthemic forms of NPEVI. In 2022, the circulation of eight more enteroviruses genovariants was recorded, among which Coxsackie A10 EV prevailed (20.5% of cases), which caused the majority of enterovirus vesicular pharyngitis cases. Enterovirus meningitis was registered in 5 (11.4%) children with the release of ECHO 6, ECHO 9, and Coxsackie A9, which were not noted in other clinical forms and circulated irregularly and in smaller numbers during the pre-pandemic period than in post-pandemic period (2022).
 CONCLUSIONS: The analysis of the monitoring data of the NPEVI in KhantyMansiysk Autonomous Okrug revealed a trend of a gradual increase in incidence in children, which must be considered when organizing epidemiological surveillance of NPEVI. The completeness of the registration of NPEVI cases with mandatory genotyping of the detected enterovirus strains will allow to more accurately determine the spectrum of strains endemic to this territory, assess the probability of their spread, forecast about the true level of morbidity, and conduct appropriate scientifically based antiepidemic and preventive measures among children with NPEVI in KhantyMansiysk Autonomous Okrug.

Сезонная динамика содержания компонентов антиокислительной системы хвои сосны обыкновенной (Pinus sylvestris L.) в зоне локального теплового воздействия

The seasonal changes in a period of low temperatures and characteristic correlations of some antioxidant system (AOS) components in pine needles influenced by a gas flare are investigated in this study. The parameters taken are total water content (TWC) in needles, peroxidase activity (AP) and selected elements of the antioxidant system of needles, such as content of carotenoids (Car), ascorbic acid (AA), catechins (Cat) and flavanols (Fl). The needles come from Scots pine trees (Pinus sylvestris L.), which grow in a gradient of environmental conditions formed in the zone of thermal field of the gas flare impact (at various distances). The gas flare is situated on the territory of the Khanty-Mansiysk Autonomous Okrug (UGRA) of Russia. Three hypotheses were subject to verification: 1) the thermal field of the gas flare during the low temperature period affects the water exchange and the AOS state of needles; 2) increase in temperature of the environment in the flare impact zone during the autumn-winter period causes the decrease in amount of moisture in needles, which is a trait of oxidative stress in cells; 3) in the functioning of а needle’s AOS, there are correlations between its components, which values depend on distance from the gas flare and environment created by it. It was found that in the thermal field gradient of the flare, there is neither an additional reduction in TWC in needles compared to the background nor signs of change in the state of AOS corresponding to the oxidative stress in the cells. The greatest impact of the gas flare on characteristics of the physiological state of pine needles is observed in the section closest to the flare. It reveals in the higher values of AP, TWC, Car and decrease in concentration of Fl and AA. The seasonal dynamics of the studied traits values do not correlate with the temperature of the environment. It indicates the indirect effect on the regulation of needle’s AOS activity. The factor and correlation analysis of the data indicate a difference in physiological state of pine needles at different distances from the flare. There is no domination of any processes in the functioning of AOS components. The observed correlations between the studied properties change according to distance to the flare. The most stable is a negative AP relationship with ofter parameters, which rise with the increased distance from the flare. The consistency degree of separate AOS components functioning is maximal in background conditions and decreases when approaching the flare. This fact is explained by the modifying effect of the flare on physiological and biochemical processes of the needle’s adaptation to specific climatic conditions of the environment.

Using the ordinalist approach in assessing the functioning of the regional system for cleaning up polluting atmospheric emissions

Subject of research: is the functioning of the regional system of the Khanty-Mansiysk Autonomous Okrug Yugra (KhMAOYugra) for the treatment of emissions from stationary sources of harmful substances into the atmosphere (RSOV) for the period from 20122020.
 Purpose of research: to develop, based on the ordinalist approach, a complex indicator a non-linear dynamic standard for assessing the effectiveness of the functioning of the RSOW based on a systematic analysis of its functioning.
 Methods of research: an ordinal approach in the formation of a non-linear dynamic standard from indicators that characterize the functioning of the system under consideration. The latter is presented as a generalized enterprise (GE), aggregating all subdivisions of enterprises in the region associated with the purification of emissions from harmful substances into the atmosphere.
 Main results of research: it was found that the greatest impact on the effectiveness of the GE is the lack of production capacities in the region for the purification of emissions from harmful substances into the atmosphere. This is confirmed by the statistical data for the specified period on the lack of commissioning of the corresponding new facilities and facilities. The obtained assessments of the effectiveness of the functioning of the RSOV were compared with the assessment of the environmental situation in the region for this type of pollution, obtained on the basis of the decoupling method, which operates with variables similar in structure.
