Mercury exposure, epigenetic modifications, and genetic susceptibility
Introduction: Mercury (Hg) is a major environmental contaminant and public health concern, particularly in industrial regions where metallurgical activities contribute to elevated Hg emissions. Genetic factors influencing susceptibility to mercury toxicity remain underexplored in Central Asia. This study investigated genetic predisposition to Hg accumulation and toxicity among residents of Temirtau, Kazakhstan. Methods: A total of 180 residents f…
Assessment of psychophysiological functions of the central nervous system in Buryat children with excessive smartphone use
BACKGROUND: Mobile devices have become an integral part of the environment of modern children. However, digital content is evolving more rapidly than scientific research on its impact on children’s health.AIM: To assess changes in the psychophysiological responses of the central nervous system in Buryat children associated with increased use of mobile electronic devices.METHODS: A two-stage examination was conducted in 262 schoolchildren of Burya…
Gender differences in sensitization to formaldehyde among urban adolescents in relation to parental chemical exposure
BACKGROUND: The burden of sensitization and allergies increases every year. The development of allergopathology can be influenced by various external factors, including the exposure of parents to chemical compounds with the subsequent impact on the child's health.AIM: to identify gender differences in sensitization to formaldehyde among adolescents of industrial cities in relation to parental chemical exposure.METHODS: A cross-sectional survey wa…
Carbon dioxide concentration in the air of school gyms during classes
BACKGROUND: Elevated levels of carbon dioxide in gym air can diminish the benefits of physical activity and pose health risks for children..AIM: to access carbon dioxide concentration in the air of school gyms during physical education classes.MATERIAL AND METHODS: A total of 612 measurements were taken to estimate the concentration of carbon dioxide in the air. These measurements were conducted in two separate gymnasiums: in Gym 1, designated fo…
Fluorine excretion in children at various levels of exposure to emissions from aluminum production
BACKGROUND: To assess the risk of development of disorders caused by excess or lack of fluorine, information regarding the levels of exposure and excretion of fluorine by various routes of intake is important.AIM: To determine the features of fluoride ion excretion in children exposed to different levels of fluorine compounds contained in emissions from aluminum production.MATERIAL AND METHODS: Observation groups were formed from 245 and 148 peop…
Health risk assessment of the population of the Republic of Buryatia associated with increased nitrate and nitrite intake
AIM: To conduct a hygienic assessment of the health risk levels associated with drinking water with high nitrate and nitrite contents in the rural territories of the Republic of Buryatia.MATERIAL AND METHODS: The content of nitrates and nitrites in drinking water in comparison with the maximum permissible concentrations (MPC) was assessed in the period of 20102019. With the use of the risk assessment methodology, non-carcinogenic risk (HQ) for ad…
The Use of Unpopulated Technologies in Open-Pit Mining
On the example of JSC SUEK, the expediency of using robotic technologies at open-pit mining enterprises in Russia is considered. The analysis of industrial safety, socio-economic factors and economic feasibility suggests the need for the use of robotic technologies in mining enterprises. The ideology and practical steps of digital transformation in mining were formed in stages. Positively influencing the efficiency of work and the level of indust…
Hygienic Conditions of Supplementary Educational Organizations and Health of Children
The aim: hygienic assessment of the conditions of stay and the study of the health status of children attending supplementary educational organizations (SEO). Methods: We performed comprehensive sanitary and hygienic examination of SEO and analysed children's health using the data from the "Children's Medical Records for Educational Institutions" (registration form 026 / у-2000). Incidence, prevalence and structure of chronic pathology as well as…
Psychophysiological Characteristics of the Central Nervous System of Rural Children of Various Ethnic Groups of Siberia
Aim: a comparative assessment of the psychophysiological parameters of the central nervous system in rural children of different ethnic groups. Methods. Rural children aged 11-17 participated in a one-stage observational survey (124 - Buryat and 132 - Slavic ethnic groups). A simple visual-motor reaction and a teping test were used to study the psychophysiological characteristics of the central nervous system. Results. The Buryat children had a h…
Influence of Air Environment Chemical Imputities on Expression of Toll-Like Receptors and Cytokine Levels of Adolescents
Emissions from oil refining, chemical industry, heat power industry, which are located in the Irkutsk region, cause a high level of air pollution in these areas. Personalized approach to assessing the risk of health disorders allows to set taxis to external influence. The aim of this study was to assess the level of expression of toll-like receptors (TLR) and cytokine content in adolescents with different risk of formation of the immune system di…
Biological Monitoring of Content of Heavy Metals in Hair of Children in the Arctic Zone of Russia
Aim of investigation. To study the content of heavy metals: zinc, iron, copper, lead, arsenic, manganese, chromium, cadmium and mercury in hair samples of children permanently residing on the territory of the Arctic zone of Russia. Methods. In the process of research, a method of atomic absorption spectrometry with flame and electrothermal atomization, the cold vapor method was used. In the transverse study, 48 children aged 7 to 17 years were in…
Characteristics of Childrens’ Physical Development in Yamalo-Nenets Autonomous Okrug
Physical development is one of the indicators characterizing the health of children and reflects the risk factors of the impact of its infringement. The article presents the results of a comprehensive assessment of physical development of Nenets-children (7-17 years old) born and residing on the territory of the Yamalo-Nenets Autonomous Okrug. It was found that in all age groups among boys and girls there is prevalence of persons with a harmoniou…
Individual Exposure Load of Formaldehyde and Adolescents’ Organism Sensibilization
All environmental factors influence on the human directly or indirectly. The biggest influence has the outdoor air, which is one of the major health risk factors associated with the environment. The proportion of 9-18 % of the total hazard index of inhalation exposure belongs to formaldehyde, which has a general toxic, sensibilizing and allergic effect. The frequency of allergic rhinitis and asthma in children living in the industrial cities of E…
Cardiohemodynamic Assessment of Indicators in Children of the Far North and Siberia
A study of the functional state of the cardiovascular system (CVS) on the basic parameters of cardiac hemodynamic in children of the Far North and Siberia has been carried out. The received data reflect the variety of ways of CVS development in children of different ethnic groups: Nenets, Buryats and Slavs. Bradycardia; reduced resistance of small vessels; implementation of the heart pump function at a high level were typical for children of indi…
Combination of Hereditary and Exogenous Risk Factors in Adolescents With Syndrome of Elevated Blood Pressure
We have comparatively analyzed the role of genetic and exogenous factors as well as clinical, laboratory and psychological data of 100 adolescents aged 15-17 years with the syndrome of elevated blood pressure. The period of the disease ranged from 1 to 84 months. It has been found that family history and excess weight were the main factors of arterial hypertension in the adolescents. This was indicated by an earlier onset of the disease (in the g…
Hygienic Assessment of Schoolchildren’s Learning Labour Intensity
It development of social life determines labor predominance in the sphere of information production, storage, processing and realization. With an increase in information flows, teaching information that should be studied by schoolchildren increases. In connection with this, research of intensification factors in education from the point of view of hygiene is very urgent. Our goal was to study learning labor intensity and assess junior schoolchild…
