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.

Wide Range

Levels of whole body ride vibration were measured on tractors and other agricultural vehicles during a wide range of normal field operations. Most of the drivers were found to be exposed to vibration levels exceeding that considered safe for 8 hours exposure per day. The highest vibration levels were on tractors doing transport tasks. Regular exposure to such vibration is considered a health risk if it exceeds 2½ hours per day. Daily vibration dose received by drivers was estimated from a sample of 60 tractor driving days. During half of these days, the drivers were exposed to a vibration dose considered by BS 6841 to cause severe discomfort and increased risk of injury. Whole body vibration on agricultural vehicles is therefore likely to be a significant long term health risk for tractor drivers.

Drivers of mining dump trucks are a group of highly qualified specialists whose training requires considerable time and financial costs. We investigate the working conditions, general and occupational pathology of the dump truck drivers of the open apatite mines in the Arctic. We carried out the analysis of working conditions and health status of 475 dump truck drivers and 534 miners of other occupations of open apatite mines, as well as the information on the occupational pathology of that workers group in 2007–2017. It has been established that the typical feature of health disorders in the dump truck drivers is the frequent development of obesity (22.9 % of workers), and occupational pathology which is in most cases due to imperfect technological processes (67.3 %), leading to an increased severity of labor and exposure to whole-body vibration. The most prevalent occupational diseases of drivers are vibration disease (36.5 %), radiculopathy (25.8 %) and mono-polyneuropathy (20.1 %). The risk of occupational pathology among truckers is higher than that one for miners of other specialties: RR = 1.35; DI 1.04-1.74. Measures aimed at health preservation of dump truck drivers should include the correction of food and work regimes, the improvement of technological processes during the transportation of ore raw materials targeted at reducing the severity of labor and harmful effects of whole-body vibration.

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.

Increased Risk

Occupational noise, hand-arm and whole-body vibration are the main human health risk factors in various economic activity sectors including agriculture. Workers of agricultural sector are usually under increased risk as their exposure to these risk factors is usually longer than reference 8 hours. Moreover, most agricultural activities are related with the processes which include multiple equipment and machinery therefore noise and vibration exposure analysis is a complex issue which is usually undeservedly simplified. This problem can be emphasized by statistical data provided by State Labour Inspectorate of the Republic of Lithuania. Occupational diseases registered for farmers, agricultural and forestry workers consist 16 % of all those registered in Lithuania. Four of five occupational diseases registered in Lithuania are related to vibration and noise (musculoskeletal (66 %) and hearing loss (13 %) and has the increasing tendency over the last years. These tendencies demand a deeper analysis of noise and vibration exposure of farmers and farm workers as obtained results could help to specify the strategy or procedure to reduce negative exposure effects. The results reveal that noise exposure level usually exceed exposure action value of 80 dBA while hand-arm and whole-body vibration exposure limit value of 1.15 and 5 m/s2 respectively.

Abstract It has been suggested that long-term exposure by heavy vehicle operators to whole-body vibration (WBV) may be related to an increased risk of pathological changes in the anatomical parameters of the hip. The aim of this study was to explore the difference in anatomical parameters of acetabulum in drivers of heavy vehicles (experimental group; n=60) and subjects who have not been exposed to WBV (control group; n=60). The anteroposterior radiographic view of the hips was used to measure the following parameters: the vertical centre edge (VCE), the ‘horizontal toit externe’ angle (HTE), the neck shaft angle (NSA) and the acetabular depth (AD). Compared with the control group, the mean VCE angle values and AD were signifi cantly lower, while the average HTE and NSA values were signifi cantly higher in the experimental group. This study supports the hypothesis that exposure to whole-body vibration during operation of a vehicle causes an increased risk of acetabular dysplasia.

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.

Three groups of 24 subjects were exposed to alternated periods of noise, vibration and combined exposures of both stimuli, recorded during working conditions in a dumper, a helicopter and a railway engine, respectively. Each condition included 30 minutes' exposure during which wakefulness and performance were measured by means of EEG and a computerized test respectively. The subjects also rated their drowsiness and annoyance. Results of the EEG measurements indicated the lowest level of wakefulness during the combined exposure in all three environments. The differences in ratings of drowsiness between exposures also tended to be higher during the period of combined exposures. The rated annoyance levels were always at the highest level during the combined exposure. Almost equal performance levels were found during the periods of exposure.

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.
