Labor activity in the Arctic, especially mining, is associated with an increased risk of developing occupational pathology. The aim of the study was to investigate working conditions, structure and prevalence of occupational pathology among workers of the Vorkuta industrial region (IR) in 2007–2018. The results of social and hygienic monitoring «Working conditions and occupational morbidity» of the population of the municipal urban district of Vorkuta and the Arctic zone of Russia in 2007–2018 were studied. It was found that in 2007–2018, 99 % of occupational diseases in Vorkuta IR were detected in coal mine workers. Only 1 % of diseases were diagnosed in workers engaged in health care, transport, construction, household services, electricity production and distribution, and industrial production. Over 12 years, the share of increased labor severity in the development of occupational diseases rose from 20.3 % to 74.0 % (p < 0.001), and the share of fibrogenic aerosols decreased from 33.0 % to 13.2 % (p < 0.001). During the same period of time, in the structure of occupational pathology the share of musculoskeletal diseases increased from 20.7 % to 56.9 % (p < 0.001), and the share of respiratory diseases decreased from 31.8 % to 13.4 % (p < 0.001). In 2007–2018, the number of occupational pathology cases tended to grow, and the risk of their development in 2016–2018 was higher than in 2007–2009 (RR = 1.90; CI 1.69–2.12; p < 0.001). The results of the study indicate the need to update programs to improve working conditions and prevent occupational pathology at the Vorkuta coal mines, taking into account the new data obtained.

Introduction. Due to the impact of adverse working conditions and climate, workers in coal-mining enterprises in the Arctic are at increased risk of occupational diseases (OD).The aim of the study was to study the working conditions, causes, structure and prevalence of occupational diseases in miners of coal mines in the Arctic.Materials and methods. Th e data of social and hygienic monitoring “Working conditions and occupational morbidity” of the population of Vorkuta and Chukotka Autonomous District in 2007–2017 are studied.Results. It was established that in 2007–2017 years, 2,296 ODs were diagnosed for the first time in 1851 coal mines, mainly in the drifters, clearing face miners, repairmen and machinists of mining excavating machines. Most often, the ODs occurred when exposed to the severity of labor, fibrogenic aerosols and hand-arm vibration. The development of professional pathology in 98% of cases was due to design flaws of machines and mechanisms, as well as imperfections of workplaces and technological processes. Diseases of the musculoskeletal system (36.2%), respiratory organs (28.9%) and nervous system (22.5%) prevailed in the structure of professional pathology of miners of coal mines. Among the three most common nosological forms of OD were radiculopathy (32.1%), chronic bronchitis (27.7%) and mono-polyneuropathy (15.4%). In 2017, coal miners in the Arctic had a professional morbidity rate of 2.82 times higher than the national rates for coal mining.Conclusions. To preserve the health of miners of coal mining enterprises, technical measures to improve working conditions and medical interventions aimed at increasing the body’s resistance to the effects of harmful production and climatic factors are necessary.

Construction is one of the most important sectors of the economy. The purpose of the study was to investigate the working conditions and occupational pathology of workers in the construction industry in the Arctic zone of Russia in 2008–2018. Materials and methods. The analysis included results of the monitoring study «Working conditions and occupational morbidity» of the population of the Arctic zone of Russia in 2008–2018. Results. It was found that in 2008–2018, 145 occupational diseases were first identified among builders. Most often occupational pathology developed in women (n = 86) who worked as painters (n = 48) and plasterers (n = 26). The increased severity of work was the cause of the development of 55.9 % of occupational pathology cases. In its structure, diseases of the musculoskeletal system (43.4 %), respiratory organs (18.6 %) and the nervous system (15.9 %) were most prevalent. The most prevalent nosological units were monopolyneuropathy, arthrosis of the joints of the extremities and sensorineural hearing loss (13.8 % each). Mainly occupational diseases (80 cases or 55.2 %) were first diagnosed as a result of workers’ self-appeal for medical help. The annual number of diagnosed diseases ranged from 5 to 27 cases. In general, over 10 years there was a trend towards an increase in the number of occupational diseases. In 2018, the risk of formation of occupational pathology among construction workers significantly exceeded the level of 2008: RR = 3.51; CI 1.65–7.46; χ2 = 12.4; p = 0.0005. Conclusion. Prevention of occupational pathology among builders in the Arctic should, first of all, include technical measures to reduce the severity of labor processes in the «female» construction professions (painter and plasterer) and medical measures to prevent the musculoskeletal diseases.

Introduction. The mining and metallurgical industries form the basis of the economy of the Murmansk Region. Working conditions at industrial enterprises, combined with extreme climatic conditions of the Arctic, pose an increased risk of occupational diseases. The purpose of the study was to investigate working conditions and occupational disease rates among industrial workers of the Murmansk Region in 2007–2017. Materials and methods. We studies socio-hygienic monitoring data on working conditions and occupational diseases in the population of the Murmansk Region in 2007-2017 provided by the Federal Center for Hygiene and Epidemiology of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare, Moscow. Results. In 2008-2017, the most common occupational risk factors in the Murmansk Region included noise (25.8%), job strain (17.8%), and chemical factor (12.6%) while 39.2% of workers were exposed to a combination of occupational hazards. Over 10 years, the absolute number of workers exposed to dangerous and hazardous industrial factors decreased by 1.8 times. In the Murmansk Region, 84.3% of occupational disease cases were registered among workers of mining and metallurgical enterprises. In 2007-2017, the region experienced a significant decrease in occupational disease incidence mainly related to job cuts. The role of other factors (improvement of working conditions, health promotion) needs to be clarified; yet, it is possible to predict their positive influence on occupational morbidity in the next few years. Conclusion. To achieve a substantial decrease in occupational disease incidence rates, it is essential to keep improving comprehensive measures aimed at preserving workers’ health in the Murmansk Region.

Musculoskeletal Pathology

Mining in the Arctic is associated with an increased risk of developing occupational diseases. The aim of the study was to assess risks of developing occupational pathology over 10-year period of mining apatite ore in the Kola Arctic open-pit mines. We studied data on working conditions (certification of workplaces), health status (periodic medical examinations) and primary occupational pathology (monitoring "Working conditions and occupational morbidity of the population of the Murmansk region" in 2009-2018) of open-pit apatite miners. It was found that, according to an overall assessment, the working conditions of all 436 surveyed open-pit apatite miners corresponded to 3.2-3.3 hazard classes. During 10 years of employment (2009-2018), 88 (20.2%) miners were first diagnosed with 134 occupational diseases, which are 3.07 cases per 100 people per year. The main cause for their occurrence was the severity of work above the permissible level (39.6%), whole-body vibration (37.3%) and noise (17.9%), and their structure is dominated by vibration disease (35.8%) and musculoskeletal pathology (30.0%). The main factor in the occurrence of occupational diseases was recognized as imperfection of technological processes (58.2%). The risk of occupational pathology formation in the excavator drivers (RR=1.95; CI 1.33-2.86; p<0.001) and in the drilling rig drivers (RR=1.60; CI 1.04-2.47; p=0.031) was higher than that of bulldozer drivers. In 2009-2018, unlike the bulldozer and drilling rig drivers, the excavator drivers showed an increased risk of developing occupational diseases (RR=3.50; CI 1.90-6.43; p<0.001). In 2009-2018, the open-pit apatite miners of the Kola Peninsula retained a high level of occupational morbidity, and it tended to increase among excavator drivers.

Introduction. It is known that in industrial workers, working conditions and climatic features of the Arctic create an increased risk of occupational diseases. Th e purpose of the study was to investigate the impact of working conditions on the structure and prevalence of occupational pathology among the working population of the gas and oil producing region in the Arctic.The aim of the study is to explore working conditions, the structure and prevalence of PP in the working population of the gas-oil-producing region in the Arctic.Materials and methods. The data of social and hygienic monitoring in the section “Working conditions and occupational morbidity” of the population of the Nenets and Yamalo-Nenets Autonomous Districts from 2007 to 2017 were studied.Results. It was found that employees in the Arctic gas and oil producing region were most frequently exposed to noise (24.0%), poor microclimate parameters (10.1%), non-ionizing electromagnetic fields and radiation (9.7%). Th e combined effect of several factors was found in 24.8% of workers. Th ere were 285 patients with newly diagnosed OD, 67.0% of whom were air transport workers, and 14.4% were employed in the gas and oil industry. Th e structure of the occupational pathology was dominated by sensorineural hearing loss (77.9%). In 2017, the regional level of occupational morbidity exceeded the national level by 1.7 times, among air transport workers — by 1.9 times, while among employees of gas and oil producing enterprises it was 5.3 times less than the national industry indicator. Th e risk of OD development among air transport workers was higher than in the region as a whole (RR = 45,88; CI 38,3–54,9), in oil and gas companies workers (RR=141,0; CI 100,8–197,2) and in workers of all types of transport, except air transport (RR =68,3; CI 39,8–117,4).Conclusion. In the Arctic gas and oil producing region, most often occupational pathology is recorded among air transport workers, which necessitates the use of a comprehensive program for its prevention. It is necessary to explain the low levels of occupational morbidity in the gas and oil production and other economic activities in the region.

Introduction. Labor in the Arctic is associated with an increased risk of developing occupational diseases.The purpose of the study was to identify changes in risk factors, structure, and prevalence of occupational pathology among employees of enterprises in the Arctic during 2007-2018.Material and methods. The analysis of the data of socio-hygienic monitoring “Working conditions and occupational morbidity” of the Russian Arctic zone population was carried out.Results. 72.6% of workers at enterprises in the Arctic were found to have contact with harmful occupational factors. Within 12 years, the proportion of individuals exposed to noise and chemical factors decreased (p &lt;0.001), while the proportion of those exposed to whole-body vibration, fibrogenic aerosols, and having increased severity of labor increased (p&lt;0.001). In 2007-2018, the number of occupational pathology cases among employees of mining enterprises increased significantly (from 38.8% to 62.8%, p &lt;0.001), while in metallurgical plants-it decreased (from 33.2% to 7.3% (p &lt;0.001). In the structure of occupational pathology, the shares of radiculopathy (p &lt;0.001) and vibration disease (p &lt;0.001) increased due to a decrease in the shares of chronic bronchitis (p &lt;0.001) and mono-polyneuropathy (p &lt;0.001). Also, characteristic features of occupational pathology were an increase in the number of diseases associated with the severity of labor (from 20.7% to 46.9%, p &lt;0.001), diseases diagnosed in one employee (from 1.006 ± 0.004 to 1.396 ± 0.030 cases, p &lt; 0.001) and the number of men among occupational patients (from 87.3% to 94.7%, p &lt;0.001).Conclusion. It is necessary to continue both improve working conditions at enterprises in the Arctic, and study the reasons for the low efficiency of prevention of occupational diseases, caused primarily by increased severity of labor in the mining industry.

Introduction: Mining in the Arctic is associated with an increased risk of developing occupational diseases. The objective of the study was to investigate the risks, structure and prevalence of occupational diseases in workers engaged in extraction of oil and gas, coal, and ore raw materials in the Russian Arctic. Materials and methods: I analyzed the results of socio-hygienic monitoring “Working Conditions and Occupational Health” conducted in the Arctic zone of the Russian Federation in 2007–2018. Results: Significant differences in working conditions in the extraction of various types of minerals were established, the most favorable being in the oil and gas industry as opposed to the coal mining. The risk of occupational diseases in coal mining was higher than that in oil and gas production (OR = 366.7; CI 275.8–487.6) and ore mining (OR = 1.66; CI 1.58–1.73). Among oil and gas industry workers, the structure of occupational diseases was dominated by sensorineural hearing loss (50.0 %), radiculopathy (20.8 %) and vibration disease (18.9 %). In coal miners, the most prevalent diseases included radiculopathy (32.8 %), chronic bronchitis (26.9 %) and mono-and polyneuropathy (15.5 %), and in ore miners – vibration disease (44.8 %) and radiculopathy (16.3 %). In 2018, compared to 2007, the number of occupational diseases in ore and coal miners increased by 2.16 and 1.42 times, respectively. In 2007–2018, the proportion of occupational diseases diagnosed in miners of the Russian Arctic rose from 57.9 % to 75.6 %. Conclusions: In the mining industry of the Russian Arctic, the maximum health risk is observed in coal mining, and the minimum – in gas and oil industry. The number of occupational diseases in miners tends to increase, which requires improvement of preventive measures adapted to Arctic conditions.

Summary. Introduction: Non-ferrous metallurgy is one of the basic economic sectors of the Murmansk Region, which workers are at increased risk of occupational diseases. The purpose of the study was to investigate causes, structure and prevalence of occupational diseases in the Kola Arctic copper and nickel industry workers in 1989–2018. Materials and methods: We analyzed data on working conditions and occupational diseases in the Murmansk Region in 1989–2018. Results: We observed the following changes in workers of the Kola copper and nickel industry during the 30-year study period: 1) the length of service until manifestation of an occupational disease increased from 46.3 ± 1.3 to 55.0 ± 0.6 years (p < 0.001); 2) the proportion of women among occupational disease cases increased from 3.6% to 33.0% (p < 0.001); 3) the number of newly diagnosed occupational diseases in an employee increased from 1.04 ± 0.04 to 2.19 ± 0.12 (p < 0.001); 4) the proportion of cases of chronic intoxication with nickel compounds in the general structure of occupational diseases rose from 6.9 % to 34.7 % while the percentage of respiratory diseases dropped from 89.7 % to 34.2 % (p < 0.001). In 1989–2008, we noted an increase in occupational disease rates with peak values (336 cases) achieved in 2004–2008. In the following decade, their number decreased by 2.7 times from 104 to 38 cases, and their share among all regional occupational disease cases dropped from 40.2 % to 16.6 % (p < 0.001). Conclusions: Respiratory diseases and chronic intoxication from exposure to nickel compounds prevailed in the structure of occupational diseases in metallurgists in the Kola Arctic. An increase in the number of occupational diseases per worker, a rise in the proportion of women among sick workers, and a sharp decline in occupational disease rates in 2009–2018 require a proper explanation.
