Ecological and hygienic problems in the Arctic territories of intensive industrial activity (review)

The Goal. To analyze the literature on the impact of high latitude climate on human health, as well as consider some aspects of adaptation to Arctic conditions and nutritional issues for the population and shift workers.Methods. Review of the articles placed in the bibliographic and abstract databases of VINITI, CyberLeninka, RSCI, Scopus, WoS, on the study of environmental and hygienic problems in the Arctic territories, where intense industrial activity is carried out. The following keywords were used: Arctic territories, adaptation, watch, food.Results. Long-term fundamental research has established that a complex of unfavorable and extreme natural and climatic factors in the Arctic causes two main syndromes in humans – “polar tension” and “northern tissue hypoxia”. Adaptation of new settlers in the Arctic territories proceeds in three stages. The duration of the shift period must have a physiological and hygienic justification and correspond to the duration of the period of stable working capacity. In high latitudes, it is especially important to develop diets and food products for various groups of the population and shift workers in relation to the specifics of their work in the Arctic regionsConclusions. Among the main environmental and hygienic problems of the Arctic territories, where intense industrial activity is carried out, it is necessary to highlight the tasks of scientific substantiation of rational modes of work and rest of workers in rotational forms of work. Also it’s necessary to define the quantitative and qualitative composition of food rations recommended for nutrition of various groups of the population, in relation to the specifics of production factors.

RISK FACTORS IN THE PROCESS OF EMPLOYMENT OF MEDICAL WORKERS OF THE DENTAL PROFILE

One of the most socially important types of work is the work of medical workers. Due to the presence of a significant number of harmful and dangerous factors, the medical profession is divided into a separate group, which in turn is characterized by unique aspects of work. The work of doctors and nurses of different specialties of the dental profile differs significantly in the density of the working day, the volume and nature of professional activities; responsibility for the life of the patient, which affects many physiological processes. The purpose. Assessment and comparative characterization of the presence of occupational risks in the dental field, which are daily exposed to factors of aggressive and dangerous nature, as well as the development of a set of preventive measures aimed at reducing occupational morbidity. Materials and methods. Hygienic research of working conditions of medical staff of the University Dental Clinic in the form of a questionnaire. Statistical analysis of data of special assessment of working conditions; sanitary and hygienic characteristics, acts, maps of cases of nosocomial diseases; laboratory and instrumental research conducted as part of production control; dosimetric control, air sampling with subsequent sowing on the nutrient medium of IPA. Results. It was found that in the studied premises, the total microbial count varied from 756 ± 0.8 CFU / 1m3 to 6497 ± 3.4 CFU / 1m3. In most medical institutions, the level of artificial lighting in the workplaces of medical workers was insufficient. The largest negative contribution was provided by such production factors as: labor intensity and intensity - 26.41%; physical: noise, vibration, non-ionizing and ionizing radiation - 25.32%; chemical - 12.77%. The total contribution of the main factors was 91.78%. Assessment of working conditions is based on hygienic criteria to assess the degree of deviations of the parameters of the production environment and labor process from the current hygienic standards, as well as after analysis and processing of data submitted by employees in the format of their questionnaires. In this regard, the distribution of harmful production factors and their degree of impact on the health of medical personnel was established with the help of multifactor analysis. Conclusions. Thus, the research interprets the results, which clearly in the format of a specific percentage, identify those factors that have a strong driving impact on the health of dental professionals. The most substantiated are such production factors as: chemical (exposure to drugs and chemicals), physical (noise and vibration, non-ionizing and ionizing radiation), the severity and intensity of the labor process, lighting (non-compliance with regulations for artificial lighting in the workplace) and microclimate and biological (work with biological, potentially contaminated material, samples, patients), non-ionizing and ionizing radiation, labor intensity (tension of the visual organs).

The Competitiveness of Agriculture in EU Member States According to the Competitiveness Pyramid Model

Agriculture in the European Union is highly differentiated, and one of the objectives of the Common Agricultural Policy is to improve agricultural competitiveness. Therefore, surveys regarding the competitiveness of agriculture and grouping countries of the European Union (EU) according to similar characteristics of agriculture are very valuable. They help make strategic decisions concerning the agricultural sector. This paper aims to evaluate the agricultural competitiveness of EU member states in 2010–2019. Data used is derived from the Eurostat and FADN (Farm Accountancy Data Network). The study employed a competitiveness pyramid model based on two groups of factors–competitiveness sources (bottom of the pyramid) and competitiveness effects. Partial components allocated to the groups mentioned above of factors were used to calculate a synthetic measure to determine the level of agricultural competitiveness in respective countries. The studies revealed that EU agriculture varies both in terms of resources and relationships between production factors, as well as the efficiency of their utilization. A clear difference in the level of competitiveness occurred between old and new member states, although some new countries ranked relatively high in terms of competitiveness sources (Czechia and Poland). Belgium scored highest for the synthetic measure of agricultural competitiveness in 2010–2019, and Cyprus had the lowest. It was demonstrated that human resources were of utmost importance in the structure of competitiveness sources. In turn, the average holding area determined the management conditions to the highest extent.

Adapting the Form of the sanitary and hygienic characteristics of working conditions to the new Sanitary Law

Introduction. The current Form No. 362-1/y-2001 "The sanitary and hygienic characteristics for the working conditions of an employee having suspicion of an occupational disease (poisoning)" does not meet the requirements of Sanitary Law developed within the framework of the "regulatory guillotine". It complicates the investigation of occupational diseases and carrying out an objective examination of the connection between the disease and the profession. The study aims to analyze the Form for the sanitary and hygienic characteristics (SHC) of working conditions and substantiate proposals for its adaptation to the current regulatory legal acts to objectify the investigation of occupational diseases cases and the examination of the connection between the disease and the profession. Materials and methods. We carried out the expert-analytical study. We analyzed and compared data from Rospotrebnadzor (2001-2020) on occupational morbidity and Rosstat (2014-2020) on employment in harmful and (or) hazardous working conditions. We also studied the SHC (503) submitted for examination of the connection between disease and profession (including forensic medical examination). The structure of the Form for the completeness of the presentation of issues on various aspects of working conditions, the quality of the compilation and content of the SHS was determined in accordance with the current Sanitary Law. The authors evaluated the structure of the Form for the presentation of questions on various aspects of working conditions, determined the quality of the compilation and content of the SHC in accordance with the current Sanitary Law. Results. With a decrease in the number of newly registered cases of occupational diseases over 20 years by more than 3.7 times, the share of workers in harmful and(or) hazardous working conditions in the main types of economic activity decreased in 2020 relative to 2014 in 1,1 time (37.3%). A comparative assessment of the standardized indicators of harmful production factors specified in the SHC and the ones approved in SanPiN 1.2.3685-21 revealed their complete inconsistency. The results of in-depth analysis of 503 SGH allowed us to determine the most typical errors in assessing production factors at workplaces: incorrect assessment of standardized single-digit noise indicators (equivalent sound level A for an 8-hour working day), vibration (equivalent level corrected along the Z-, Y-, X-axes ); lack of data on dust load and the average value of air temperature - THC-index; assessment of the labour severity without considering the technological operations performed, etc. We noted the predominant assessment of working conditions by the main factor developing an occupational disease, without considering the accompanying risk factors that aggravate its effect. We also noted a significant underestimation of the levels when assessing the general transport, technological and technological vibration due to the differences between hygienic standards and the norms adopted in the Methodology for conducting a special assessment of working conditions. SCH contains no information on lighting, biological factor, labour intensity in 67.0-75.0% of cases. Conclusion. We substantiated proposals for improving Form No. 362-1/y-2001 of the SHC of working conditions, considering an electronic form of the document, revising the instructions for filling out the SHC.
