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. 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.

Background: Improvement of working conditions at enterprises of various sectors of economy can be achieved by solving comprehensive organizational, social, legal and other tasks. The purpose of the research was to study working conditions and occupational morbidity of workers of various industries in the Republic of Bashkortostan in 2000–2019. Materials and methods: We analyzed working conditions of the population employed at the enterprises of the republic and occupational disease rates. Results: Most occupational risk factors were attributed to imperfection of technological processes, equipment and design flaws of machines, mechanisms, equipment, devices and tools. More than a third of cases of occupational disorders were diseases of the musculoskeletal system while every fifth case was that of a respiratory disease; radiculopathy and vibration disease prevailed among nosological forms. Men exposed to general vibration were most at risk of developing occupational diseases, including those induced by other occupational risk factors. At enterprises of mining, construction, and manufacturing industry, working conditions usually failed to meet sanitary and hygienic requirements for physical work heaviness, noise and chemical exposures, in agriculture – for physical work heaviness, and in transport and communications – for work heaviness and intensity. Conclusion: We observed a steady increase in the proportion of employees exposed to occupational risk factors and/or hazards and a simultaneous decrease in registered occupational disease incidence rates.

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.

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.

Introduction. Working conditions at mining enterprises, including iron ore mining, combined with the climatic conditions of the Arctic, create an increased risk of occupational diseases (OD) among miners. The aim of the study was to investigate the risks, circumstances of the development, structure, and prevalence of OD in miners engaged in the extraction of iron ore in the Kola Polar Region. Material and methods. The data of social and hygienic monitoring in the section “Working conditions and occupational morbidity” of the population of the Murmansk region in 2007-2017 were studied. Results. The development of the OD in this category of miners was established to be mainly associated with the whole-body vibration (42.5%) and the severity of labor (33.2%) due to the imperfection of workplaces (66.4%). In the structure of the OD, the largest share belongs to injuries, poisoning and some other consequences of external causes (46.9%), while diseases of the musculoskeletal system occupy the second place (27.0%). The most common nosological form of OD was vibration disease (38.5%). The annual number of workers diagnosed with OD varied over a wide range from 3 to 29 people. In 2007-2015, there was a tendency towards an increase in occupational morbidity rates, and in 2016-2017, there was a sharp decrease to 7.39 cases per 10,000 workers, which cannot be explained by improved working conditions and health promoting activities. Conclusion. To preserve the health of miners engaged in the extraction of iron ore in the Kola Arctic, it is necessary, first of all, to reduce the levels of whole-body vibration and severity of labor processes in combination with the introduction of medical methods to increase the body’s resistance to harmful industrial and climatic factors.

Introduction.High levels of occupational incidence in coal miners of the Kemerovo Region determine the need to optimize the State Committ ee for Sanitary and Epidemiological Oversight for in-depth study of risk factors and planning of medical and preventive measures.The aim of the studyis to optimize the activities of the State Committ ee for Sanitary and Epidemiological Oversight in the planning of supervisory and sanitary measures aimed at reducing the level of OD in the coal industry.Materials and methods.On the basis of a sample of materials from the database of the Department of State Committ ee for Sanitary and Epidemiological Oversight in the Kemerovo Region on the occupational morbidity of miners for 2008–2016, the analysis of data on working conditions, age, experience, dynamics of occupational morbidity. Th e information on 7515 cases of occupational diseases in workers of coal mining enterprises is analyzed.Results.Indicators of occupational disease in the miners of the Kemerovo Region are higher than the national level, amounting to 13.23 per 10 thousand of the employed population. Employees of the main professions of the coal industry are particularly susceptible to occupational diseases: sinkers, miners of treatment faces, machinists of mining excavation machines, underground electric locksmiths, drivers of heavy vehicles, drivers of excavators and bulldozers. The reasons for the formation of occupational diseases in miners are unfavorable working conditions: physical overload, dust and gas contamination, noise and vibration, high humidity of the working area at low temperatures. Occupational diseases are more commonly diagnosed in workers aged 41 to 50 years (28.01%) and 51 to 60 years (69.23%). Th e most at risk of occupational disease are those working in contact with the harmful production factor for 21–30 years (60.5%) and from 31 to 40 years (26.1%).Conclusions. The results of the study are necessary for the rational planning of control measures and reasoned conclusions in the preparation of sanitary and hygienic characteristics of working conditions with suspicion of occupational diseases.

Hazard Characterization

The paper dwells on examining mortality among men due to malignant neoplasms (MNs) in Russia and in Norilsk and Monchegorsk, two monotowns located in the Arctic zone with the only industry there being nickel production. Nickel is a well-known carcinogen. Given rather small population numbers in these two towns, the authors calculated mortality due to MNs that was aver- aged over 8 years (2010–2017) for 5-year age groups and standardized mortality ratios (SMR) for employable and post- employable ages as per this nosology in general and specific MNs localizations as well. Mortality was comparatively analyzed in two male populations in the following pairs: Monchegorsk and Russia, Norilsk and Russia; the analysis was based on data on climatic peculiarities in the towns, working conditions at industrial enterprises, ecological situation, and socioeconomic features including an existing situation in public healthcare. Socioeconomic welfare and public healthcare quality were close to average Russian ones in Monchegorsk, but SMR for employable population was higher than on average in the country: due to MNs in general, by 34.7 %; nickel-specific MNs such as MNs of the lip, mouth, and throat, by 2.2 times; MNs in the stomach, by 1.5 times. In Norilsk working conditions were similar to those in Monchegorsk but the environmental conditions were worse; still, mortality among employable population was lower: due to MNs in general, by 15.4 %; MNs of the lip, mouth, and throat, by 14.0 %; due to MNs in the stomach, by 39.3 %. In comparison with Russia as a whole, mortality due to MNs was also lower at employable age but higher by 21.6 % at post-employable one. A decrease in MNs-related mortality and carcinogenic effects becoming apparent at older ages were achieved due to organizing up-to-date oncologic aid in Norilsk including high-tech diagnostic, treatment, and rehabilitation procedures as well as due to higher living standards in the town.
