The relevance of study arises from the great number of objects of accumulated environmental damage (OAED) in the Russian Federation and the necessity to identify those that are subject to immediate elimination. \u0000The aim of this study was to test methodical approaches to estimating actual OAED, assign them into categories, and rank them as per health risk indicators; also, we generalized the results obtained by estimating 192 objects in 2022. \u0000Materials and methods. Fuzzy set theory was used as a methodical base for analyzing the results. Method makes it possible to analyze a great number of both quantitative and qualitative heterogeneous variables, as one complex. Matrices with each indicator estimated in terms of influence on human health were filled in for each type of objects. \u0000Results. Health risk assessment did not identify any objects that could be assigned into an ‘extremely high risk’ category. 17 OAED (8.9 %) were ranked as ‘high risk’ objects (R=0.76÷0.60). 101 OAED (52.6 %) – as ‘average risk’ objects (R=0.39÷0.58). 72 objects (37.5 %) created ‘moderate risks’ (R=0.45÷0.21). Two objects were considered ‘low risk’ ones (R=0.33÷0.20). \u0000Limitations. Quantitative data describe only 192 examined objects located in specific geological and climatic-geographical conditions. \u0000Conclusion. The study results give evidence that applied methods are relevant, flexible, and provide correct comparative estimations of OAED of various origin, types of accumulated wastes, existence, and locations. The regulatory and legal base for estimation of ОАЕD further development considering health risk indicators for determining priority of its elimination. Targeted studies with elements of human biomonitoring would become an additional factor providing more solid evidence of OAED negative effect on health, which allows determining the relevance of the elimination of the object assessment of the effectiveness and efficiency of measures to eliminate objects.","PeriodicalId":12550,"journal":{"name":"Gigiena i sanitariia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43795960","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}

Development of a sensitive and selective method for the determination of phenol and catechol in the whole blood by HPLC. \u0000Materials and methods. The studies were carried out on a Shimadzu liquid chromatograph with an RF-20A fluorimetric detector. The efficiency of extraction of analytes from the matrix was checked by methods of liquid and solid phase extraction, QuEChERS. The metrological parameters of the measurement technique were experimentally established.

The developed method makes it possible to determine phenol and catechol in whole blood at the level of 0.005–0.5 mg/dm3 with an error of ≤33%. The degree of extraction of phenol from whole blood by the QuEChERS method is 100%, pyrocatechol – 75%. A significantly higher (p ≤ 0.05) average group content of phenol and pyrocatechol was established in the whole blood of children living in an ecologically loaded area compared to a conditionally clean area by 2.1 times. \u0000Limitations. The study of the content of phenol and pyrocatechol in the whole blood in the child population is limited by the number of territories and examined children. To establish the background content of phenol and catechol in the whole blood of the child population at the population level under conditions of environmental stress and outside the zone of anthropogenic influence, it is necessary to conduct more extensive studies in various territories covering a larger number of examined children. \u0000Conclusion.

Most of hygienic evaluation methods of water objects are based on physicochemical analysis of water samples. These methods can’t be considered as consistent in determination of full range of pollutants. Sanitary chemical analysis of water environment, coupled with biological testing seems to be more informative. One of the most prospective research trends nowadays is using human cell lines as test objects. During the preparation of this review, there were used following database sources: Scopus, Web of Science, PubMed, RISC. As a conclusion of performed sources analysis, we can point at high sensitivity of cell lines, extracted from human digestive (Caco-2, HepG2) and excretory systems (HEK-203) to the influence of pollutants taken from different water sources. The data obtained by the authors indicate both a cytopathic effect and a change in the cytochemical and cytomorphological characteristics of cell cultures under the influence of pollutants in water. The use of human cell cultures as test objects in water biotesting is an urgent direction in the study of water supply sources for drinking and household needs of the population without preliminary purification. The use of human cell cultures in the biotesting of water makes it possible to give not only a toxicological characteristic of water samples, but also to assess the possibility of developing an undesirable effect associated with the ingress of pollutants into the internal environment of the body.","PeriodicalId":12550,"journal":{"name":"Gigiena i sanitariia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47958366","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}

One of the important directions of medical and psychological research is the scientific search for approaches and research methods in the field of adaptive resources of the individual necessity to maintain optimal performance and successful functioning of a specialist in occupational activity. At the present stage, the indicators of the functional state of the employee are taken into account and analyzed according to average values, without taking into account personalized data. This approach may lead to inaccuracies in the interpretation of the results obtained. \u0000The purpose of the study is to determine the most significant criteria for assessing the functional state of railway transport workers based on the analysis of the database of the automated system of pre‒trip medical examinations (KAPD-01-ST complex, ASF), taking into account the previously established individual threshold values of their current functional state indicators. \u0000Materials and methods. As part of the work, the database of the system of pre-trip medical examination of four hundred employees of locomotive crews was analyzed. Among them, 200 people (according to the assessment of their psychophysiological state) were classified as a “risk group”. The average age (not included in the “risk group”) is 51.4 ± 2.8 years; those included in the “risk group” ‒ 51.6 ± 3.5 years. \u0000Results. According to the results of factor analysis (CMO = 0.737, Barlett sphericity criterion p<0.05), 5 factors were identified. The cumulative percentage \u0000on the last component is 94.723. Based on the study of the results of the automated system of pre-trip medical examination (ASP), the most significant indicators \u0000of assessing the functional state of employees of locomotive crews of railway transport in the formation of a “risk group” were identified. \u0000Limitations. The representativeness of the sample size was ensured by the participation of 400 employees of locomotive crews in the study. The limitations of the study are related to the distribution of respondents by gender: there are no female respondents in the sample. \u0000Conclusion. The previously applied approaches of the system, the assessment of the functional state of the employee according to group criteria, taking into account the average values, do not allow today to obtain a forecast of occupational reliability that meets modern requirements.

The working conditions and chronic non-infectious morbidity (primary, accumulated) of workers in the production of polyacrylonitrile (PAN) fibers were studied according to the data of in-depth medical examinations (2017–2021). \u0000Results. Workers of modern production of PAN fibers in the course of their work were shown to be exposed to the combined effects of a complex of chemicals of 1–4 hazard classes, industrial noise, severity and labour intensity, which form an occupational health risk, assessed by hygienic criteria in categories from small (class 3.1) to high (class 3.3). The first ranking places in the nosological structure of accumulated chronic non-infectious morbidity of workers were occupied by dorsalgia (24.23%), essential (primary) arterial hypertension (14.67%), obesity (9.9%) and presbyopia (8.87%). Positive associations of weak age strength with arterial hypertension, obesity, and presbyopia were revealed (Rxy=0.280, Rxy=0.121, Rxy=0.133, respectively).

To achieve that, we accomplished a systematic review of relevant information sources using PRISMA recommendations on how to perform a systemic review of research articles. Overall, we analyzed more than two thousand sources to identify their relevance to the aim of this study; ultimately 64 sources were selected for analysis. \u0000Results. Within this review, three groups of novel foods of animal origin were identified and considered. They were the most frequently mentioned in studies investigating potential health hazards for humans. We analyzed these potential hazards caused by consuming novel foods; it was established that attention should be paid to probable changes in biological values of protein in a novel food, undeclared or unintended chemicals in it, and hyper-reactivity of the human immune system. Besides, when insect or GM-animal proteins are used as food raw materials, a probability of pathogenic microorganisms in them should not be neglected.

In modern medical practice, fluoxetine hydrochloride (prozac), referred to the group of highly effective antidepressants, is widely used for the treatment of mental disorders. In Russia, the domestic production of the drug with an economically feasible production technology has been managed. \u0000In the synthesis of fluoxetine, the most important stage is the preparation of the main intermediate – 3-methylaminopropiophenone hydrochloride. Data on the toxic effect of this substance on the body in the open press, including in the international database PubChem, are not available. \u0000The research aim was the study on the toxic effect of 3-methylaminopropiophenone hydrochloride on the body of laboratory animals. \u0000Materials and methods. When studying the toxic effect of 3-methylaminopropiophenone hydrochloride in experiments on rats, the modes of single inhalation and subacute intragastric methods of exposure were reproduced. The effect of the substance on the condition of animals was assessed by the results of peripheral blood studies, biochemical blood serum parameters, morphological changes in internal organs including liver, kidneys, heart, stomach, pancreas and thyroid glands. Integral parameters were also used. \u0000Results. The results of the examination of animals subjected to acute inhalation intoxication and subacute intragastric exposure showed the same type of the changes in the peripheral blood and biochemical profile. The intake of 3-methylaminopropiophenone hydrochloride did not cause significant changes in the peripheral blood. The biochemical profile of the animals showed an increased activity of AST, ALT and alkaline phosphatase. In the blood serum of the primed rats, an increased content of total cholesterol, triglycerides and urea with a reduced content of protein and bilirubin was found. The impact of 3-methylaminopropiophenone hydrochloride at the morphological level revealed vascular disorders in all internal organs and moderately severe fatty degeneration of the liver and kidneys. In some parts of the liver, there was small-focus multi-lacular necrosis which covered groups of hepatocytes. \u0000Limitations.
