This trend is almost equally characteristic of most countries over the world: from Great Britain, Germany, and Scandinavia in Europe to China, Japan in Asia and Nigeria in Africa, and, over the last decade, in Russia. In other words, the problem under consideration is global in nature and depends little on the level of economic development of the country and its ethno-geographical characteristics. \u0000Purpose of work. Study foreign and domestic scientific literature directly related to the problems of creating working conditions and their impact on the health in education workers. \u0000The presented review is based on the publications of a number of domestic and foreign studies. The literature search was carried out using the databases Pubmed, Scopus, Web of Science, MedLine, RSCI. A total of forty two publications were analyzed for the period from 2001 to 2022. \u0000A systematic analysis of the world scientific literature was conducted on the management of events aimed at assessing the working conditions and health in teachers. The study examined various aspects related to the provision of medical care to education workers. \u0000After evaluating the results of the study, it became clear that there is some discrepancy between reports in the field of psychology and hygiene. In the first group of works devoted to the psychological aspect, insufficient attention is paid to the study of working conditions and their impact on the health of teachers, despite the widespread prevalence of professional burnout syndrome among the teaching community. At the same time, in the second group of studies devoted to hygienic aspects, the role of psychosocial factors influencing the health of teachers is not sufficiently addressed. \u0000Conclusion. In general, the analysis of the characteristics of working conditions and health of pedagogical workers allows concluding this topic to be relevant and in demand in the scientific world. It also highlights the need for further research and development in this area to improve diagnosis, treatment, and prevention of related diseases.","PeriodicalId":13009,"journal":{"name":"Hygiene and sanitation","volume":"26 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140239975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cadmium chloride is an inorganic compound containing cadmium, a heavy metal that is one of the active environmental pollutants today. Damage to organs in experimental animals due to cadmium poisoning is similar to that in humans. In this work, the activity of metallothionein and zinc transporters genes was studied in a chronic model of cadmium-induced poisoning in experimental animals. \u0000Materials and methods. The experiment was carried out using seventy two individuals of white inbred rats of both sexes, the average weight of which was 215 g. Animals from four groups were injected with a solution of cadmium chloride in four different doses, respectively, individuals of the fifth group, the control group, received an equimolar volume of pure water. The objects of the study were the kidneys and livers of rats, removed after the animals were withdrawn from the experiment. Next, the activity of the Mt1A, Mt2A, Mt3A, Zip1 and Znt1 genes was analyzed in organ samples using real-time PCR. \u0000Results. Significant increases in the expression multiplicity of Mt1A, Mt2A and Mt3A metallothionein genes in the kidneys at different doses of the toxicant were revealed. In liver samples, a decrease in the expression of the Mt2A gene was found in the experimental group exposed to cadmium chloride at a dose \u0000of 0.1 mg/kg (p<0.05). For the Znt1 gene in rat liver tissue, there was a statistically significant decrease in expression at a dose of 0.001 mg/kg (p<0.05) \u0000and, conversely, an increase at doses of 0.1 and 1 mg/kg (p<0.05) compared to the control group. Analysis of the level of transcripts of the Zip1 gene in the kidneys and liver after 6 months of inoculation with the toxicant in the presented doses did not reveal statistically significant differences between the groups. \u0000Limitations. Laboratory animals of the only biological species were used for the experiment. Four doses of the cadmium salt alone were evaluated. \u0000Conclusion. The results obtained allow concluding that the level of expression of the Mt1A, Mt2A and Mt3A genes in the kidneys can play the role of a diagnostic marker in chronic poisoning with the toxicant under study.","PeriodicalId":13009,"journal":{"name":"Hygiene and sanitation","volume":"124 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140237846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chemical compounds possessing of a neurotropic effect are extremely widespread in industry, which makes the problem of neurotoxicity relevant for occupational medicine. Since industrial workers are often exposed to a combination of both physical and chemical work-related risk factors, a complex adverse health effect of the latter should be considered. \u0000Our objective was to study neurotoxic effects of exposure to cadmium chloride combined with physical activity in a subchronic experiment on rats and assess the efficacy of a biological prophylactic complex. \u0000Material and methods. For six weeks, 0.77 mg/kg b.w. of cadmium chloride was intraperineally instilled to outbred male albino rats thrice a week. Five times a week, the rodents were forced to run for 10 minutes at a speed of 25 m/min. During the entire exposure period, half of the animals received a specially developed bioprophylactic complex consisting of pectin, monosodium glutamate, and a multivitamin/multimineral supplement with feed and drink. \u0000Results. In combination with physical activity, cadmium exposure caused depression, anxiety, low exploratory behaviour, and spatial memory disturbances. The developed bioprophylactic complex helped mitigate toxic effects of cadmium aggravated with intense physical activity and improve the general condition of the rodents. \u0000Limitations. The experiment was limited to examining the behaviour of male rats following subchronic exposure to a single dose of cadmium. \u0000Conclusions. Subchronic exposure to cadmium combined with physical activity can induce certain neurotoxic effects. Administration of the specially developed complex of biological protectors has shown to attenuate or minimize these effects. Similar measures can be taken to diminish risks of adverse health consequences of the factors studied.","PeriodicalId":13009,"journal":{"name":"Hygiene and sanitation","volume":"6 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140239845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is relevant due to the necessity to adequately assess the effectiveness of activities performed within the “Clean Air” Federal Project using ambient air quality and public health risks as key performance indicators. The purpose of the work was to comparatively assess ambient air quality and airborne health risks for Bratsk population over 2020 –2022 when activities planned within the “Clean Air” Federal Project were being implemented in the city. Materials and methods. The analysis was based on data obtained by instrumental measurements of ambient air quality performed within social-hygienic monitoring programs. More than thirty thousand measuring results were considered; they covered 20 chemicals and were taken at two monitoring posts. Carcinogenic and acute and chronic non-carcinogenic health risks were assessed in conformity with the existing regulatory documents. Results. Between 2020 and 2022, a decrease in ground levels of particulate matter, sulfur dioxide, nitrogen oxides, hydrogen chloride, and some other technogenic chemicals was registered at social-hygienic monitoring posts in Bratsk. These chemicals were subject to specific activities stipulated by the “Clean Air” Federal Project and performed by economic entities. However, public health risks remained impermissible. Thus, an acute risk of respiratory diseases equaled 3.24 during 2022 and a chronic risk of respiratory diseases reached 5.43 in the same year whereas their permissible level should not exceed 3.0. Limitations. Analysis is possible only if there is a sufficient number of instrumental studies at points located in residential buildings to assess the risk (least 300 one-time or 75 daily samples for each impurity).
