The most hygienically safe process of recycling polymers is mechanical recycling, which does not cause the destruction of polymers, products of which dangerously affect all components of the environment and man. The purpose of the study is to predict the non-carcinogenic risk to public health from the production of mechanical processing of secondary polymers, depending on the presence or absence of the stage of mechanical activation in the processing process. Materials and methods: sanitary-epidemiological examination; risk assessment of dangerous factors for public health; instrumental assessment methods; statistical processing of results – determination of arithmetic mean values, standard error, quadratic deviation. Results and discussion. It is established that the total indicators of air pollution by polymer dust, nitrogen dioxide and carbon monoxide do not exceed the permissible level of pollution, and the degree of danger of this category of production is assessed as safe. Analysis of the obtained values of hazard coefficients of chemicals for the production of mechanical processing of secondary polymer raw materials without the stage of mechanical activation showed that the risk level for the maximum concentration of polymer dust and nitrogen dioxin at a distance of 25 m is assessed as alarming. The hazard factor for the maximum concentration of carbon monoxide at all distances studied did not exceed the permissible limits. For the production of mechanical processing of secondary polymer raw materials with the stage of mechanical activation, the level of risk for any of the test substances and at all distances studied did not exceed the allowable. Conclusion. Indices of danger of impact on individual organs and systems of the body (respiratory system, central nervous system, cardiovascular system, blood, eyes) of the investigated substances (polymer dust, nitrogen dioxide, carbon monoxide) at a distance of 50 m from the processing of secondary polymer raw materials without stages of mechanical activation are admissible, and for production with a stage of mechanical activation – minimum. It is established that according to the indicators of non-carcinogenic risk, sanitary-protection zone of production facilities for mechanical processing of secondary polymer raw materials without the stage of mechanical activation cannot be less than 50 m, and with the stage of mechanical activation can be reduced to 25 m

Introduction. Th e study of the infl uence of air pollution on the health of the population of industrial cities is an urgent task of preventive medicine.The purpose of the study— assessment of risk for population health of the city of Novokuznetsk, associated with the receipt in atmospheric air of polluting substances from SC «Kuznetsk TPP».Materials and methods.The paper presents the results of risk assessment for the health of the population of Novokuznetsk from the impact of atmospheric emissions of coal thermal power plant. Risks were calculated in accordance with the «Guidelines for the assessment of public health risks from exposure to chemicals that pollute the environment».Results.It was found that sulfur dioxide, coal ash, nitrogen dioxide had the largest share in the index of non-carcinogenic hazard of emissions. Th e maximum hazard index of carcinogenic substances was detected in hexavalent chromium. Th e greatest risk of immediate action, manifested in the development of refl ex reactions, was detected at two points of exposure to concentrations; it was determined by the infl uence of coal ash. In the formation of the risk of chronic intoxication, coal ash, sulfur dioxide, nitrogen dioxide, nitrogen oxide had the greatest impact; the greatest risk was detected at three points. Th e hazard coeffi  cients of the concentrations ranged from 2.04×10–4 to 6.723. The maximum index of danger equal to 29.31, corresponded to the residential district of Lenin square. Th e highest levels of carcinogenic risk identifi ed at three points were determined by exposure to hexavalent chromium.Conclusion.Th e work identifi ed environmentally disadvantaged neighborhoods of the city. It is shown that the main contribution to the formation of non-carcinogenic risk of health disorders of the city’s population is made by nitric oxide and nitrogen dioxide, coal ash, sulfur dioxide. Th e main carcinogen is hexavalent chromium. Th e total values of risks expressed in the multiplicities of excess of acceptable risk, for most points exceed 1, indicating a signifi cant impact of emissions on the health of the population. A set of atmospheric protection measures aimed at reducing risks to public health is recommended.

Human economic activity leads to the accumulation of anthropogenic contaminants in food. The aim of the study was to analyze the public health risk associated with the oral intake of organochlorine pesticides (HCH, DDT), which are widely used in agriculture. The risk assessment was carried out taking into account data on the actual nutrition of 1798 people (823 men and 975 women) aged 18 to 65 years using the Nutri-prof software package. To assess the contamination of food with organochlorine pesticides, 16510 samples of various food groups were analyzed. The greatest non-carcinogenic risk due to the intake of HCH into the body with food is due to the consumption of bread and bread products, vegetables and melons, potatoes, milk and dairy products; meat and meat products, milk and dairy products. The highest level of total individual carcinogenic risk for DDT and HCH, taking into account the median concentration, corresponds to the third range and is acceptable for professional groups. The excess of the background risk values for the endocrine system in the consumption of bread and bakery products occurs at the age of 45, the transition from a negligible level of risk to a level of moderate risk occurs at the age of 65. The results obtained indicate the effectiveness of the system of sanitary and epidemiological surveillance over food safety, the methodological approach to risk assessment under consideration allows making timely management decisions, taking into account the nature of work and nutritional characteristics.

Introduction. Th e development of the metallurgical industry in Novokuznetsk, Kemerovo region, has led to a diffi  cult environmental situation. Determining the relationship between exposure to atmospheric emissions and the health of the population based on the risk assessment methodology is an urgent hygiene issue. The aim of the study is to assess the risk of health problems from emissions from rolling production of a metallurgical plant.Materials and methods. We used data from the volume of maximum permissible emissions of the enterprise. Calculations of maximum single and average annual concentrations of pollutants were carried out using the program “ECOcenter-Standard”. Public health risks were calculated and compared with acceptable values. Th e work also determined the values of risk levels taking into account background concentrations.Results. Priority pollutants were identifi ed: diiron trioxide, nitrogen dioxide, nitrogen oxide, sulfur dioxide, carbon monoxide, benz(a)pyrene. Th e maximum one-time and average annual concentrations of substances at the selected calculation points were determined, and the maximum permissible concentration of diiron trioxide was found to be exceeded. Immediate action risk levels are zero. The highest risk levels of chronic intoxication, expressed as a percentage of a unit, are observed from exposure to diiron trioxide (0.004-0.043) and nitrogen dioxide (0.001-0.012). The maximum total level of risks of chronic intoxication (0.012) is observed at the point of exposure to concentrations #3 from the infl uence of nitrogen dioxide, which is due to the close location of pollution sources. The carcinogenic risk from exposure to benz(a)pyrene ranges from 1×10-8 to 9×10-8 (as a fraction of a unit). The combined values of carcinogenic risk and immediate action risk are below the acceptable risk level. In seven points of exposure to concentrations, the total risk of chronic intoxication exceeds the acceptable level by 1.10-3.45 times.The greatest risk of immediate action, taking into account background concentrations, is observed from the action of carbon monoxide and benz(a)pyrene. Th e carcinogenic risk exceeds the acceptable level by 6-12 times. The risk of chronic intoxication, taking into account the background, exceeds an acceptable level. Th e highest total risk levels are typical for the Kuznetsky district of Novokuznetsk. Conclusions. Atmospheric emissions fr om rolling mill production contribute to air pollution in the city, increasing the risk of chronic intoxication.

Annotation. The most hygienically safe process of recycling polymers is mechanical recycling, which does not cause the destruction of polymers, which dangerously affect all components of the environment and man. The purpose of the study is to assess the level of risk of adverse effects on the health of the population living under the influence of mechanical processing of secondary polymers, depending on the presence or absence of the stage of mechanical activation in the processing process. Research methods: sanitary-epidemiological examination; risk assessment of dangerous factors for public health; instrumental assessment methods; statistical processing of results – determination of arithmetic mean values, standard error, quadratic deviation. It was found that the total indicators of air pollution, calculated on the maximum concentrations of specific pollutants at distances for the processing of polymers without the stage of mechanical activation of 15 m – the level of pollution was assessed as alarming, and at distances of 25 and 50 m as acceptable. For the process of processing polymers with a stage of mechanical activation, at all distances from the emission source (15, 25 and 50 m) the level of contamination was assessed as acceptable. To assess the impact of air pollution in the area of impact of polymer processing on the health of the population, the risk factors for the development of non-carcinogenic effects are more informative than the indicators of pollution. The critical human organs and systems most affected by polymer processing are: the respiratory system, the cardiovascular system, the liver, the kidneys, the central nervous system, and the blood. In order to reduce the man-caused load of enterprises for mechanical processing of secondary polymer raw materials, it is necessary to introduce in-depth purification units for air emitted into the atmosphere and switch to safer fuels.

Co Intoxication

Carbon monoxide (CO) is a toxic gas produced as a result of incomplete combustion of organic materials. The source of CO production is very common especially in nations that depend on power generating sets for electricity. Chronic disease is non-communicable and usually takes a longer time to manifest. Examples are kidney failure, diabetes mellitus, hypertension, cancer, and cardiac arrest. These diseases are now very common in society, not sparing the youthful population that was rare ab initio. The major difficulty in the containment of chronic diseases is the inability to establish a definitive causative agent. The definite causative agent is important in public health and management of chronic diseases. Preventive medicine is anchored on establishing the causative agent of a disease. Without knowing the causative agent of a disease, the path to prevention becomes very cumbersome. The knowledge of the causative agent of a disease is the bedrock of preventive medicine and public health. Several reasons such as lifestyle modification, hereditary, climate change, nutrition or aging have been adduced as the cause of chronic diseases. These reasons are quite weak and not definite. The exact causative agent(s) of chronic diseases is a conundrum that needs a deliberate study and review so as to enhance definite diagnosis, preventive measures and appropriate therapeutic intervention. Measurement of biochemical and haematological parameters are employed in disease diagnosis and management. Alterations of these parameters are used to identify chronic diseases and also form part of an alarm system of a potential breakdown of the normal functioning of the body. The effect of chronic CO intoxication on these parameters could be of importance in establishing causative agent(s) of diseases that are for long opaque and non-definite. This review was therefore designed to interrogate various narratives, meta-analysis, and researches on this subject. Explicit knowledge of the pattern or presentation of biochemical and haematological parameters arising from chronic CO intoxication could be of great importance in preventive medicine, disease diagnosis and appropriate therapeutic intervention.

The relevance of research is particularly high for the Central Black Earth Region due to the high population density and the presence of numerous dispersed sources of environmental risk with a chemical type of impact on natural waters. People are forced to use water that does not meet health standards for drinking purposes, which poses a serious threat to their health. The article presents the results of calculating the non-carcinogenic risk from exposure of the body to priority chemicals (iron, manganese, nitrates) contained in the drinking water supply sources of the region, based on average annual concentrations at 174 monitoring points of control (m.t.c.) of the distribution network in settlements Voronezh Oblast. Methods. As a methodological basis for assessing environmental risks, the regulatory document R.2.1.10.1920–04 “Guidelines for assessing the risk to public health when exposed to chemicals that pollute the environment” was used. Results. According to the results of the study, it was revealed that nitrates remain the dominant indicator of drinking water pollution in the region. Calculations showed that in 9 settlements of 7 districts of the Oblast and the city of Voronezh (19 m.t.s. out of 174), the quantitative value of the non-carcinogenic risk poses an objective threat to the health of both children and adults living in these territories. The practical significance of the work is determined by the possibility of using the results of the study to improve regional water policy and increase the environmental safety and comfort of water use in the region.

The current use of serum retinol concentrations as a measurement of subclinical vitamin A deficiency is unsatisfactory for many reasons. The best technique available for vitamin A status assessment in humans is the measurement of total body pool size. Pool size is measured by the administration of retinol labelled with stable isotopes of carbon or hydrogen that are safe for human subjects, with subsequent measurement of the dilution of the labelled retinol within the body pool. However, the isotope techniques are time-consuming, technically challenging, and relatively expensive. There is also a need to assess different types of tracers and doses, and to establish clear guidelines for the use and interpretation of this method in different populations. Field-friendly improvements are desirable to encourage the application of this technique in developing countries where the need is greatest for monitoring the risk of vitamin A deficiency, the effectiveness of public health interventions, and the potential of hypervitaminosis due to combined supplement and fortification programs. These techniques should be applied to validate other less technical methods of assessing vitamin A deficiency. Another area of public health relevance for this technique is to understand the bioconversion of β-carotene to vitamin A, and its relation to existing vitamin A status, for future dietary diversification programs.

Abstract The inclusion of polysaccharide thickeners in the recipes of sweet dishes increases the functional reserves of the body, contributes to the preservation of health and the prevention of diseases. The purpose of the research is to study the sensory characteristics of polysaccharides of various nature when combined with food acids, to develop a recipe for a basic mixture of low-calorie meals for public catering. The authors analyzed citric, lactic and succinic acids in combinations with polysaccharides of various nature. Organoleptic tests were evaluated by a touch panel. The organization of the tasting analysis corresponded to GOST ISO 6658-2016; the consistency was determined according to GOST 31986-2012, GOST ISO 11036-2017, GOST ISO 8588-2011. The optimal organoleptic combinations of the presented food acids and complex additives of sweeteners (CDP) were identified, which included aspartame, sodium saccharinate, Sucralose, sweetness coefficient – 340: the mixture with citric acid had a long pleasant aftertaste without foreign tastes and the best taste characteristics. Using the “A-not A” method, we found that the sample with the addition of CDP is identical to the sucrose solution. In the second part of the study, polysaccharides were added to model samples of acids with complex sweeteners; the best sensory characteristics were obtained by model samples consisting of a mixture of low-esterified Apple pectin with lactic acid and KDP. The technology of obtaining a stable elastic jelly using low-esterified Apple pectin has been developed, since the complex mixture of sweeteners and food acids does not have a dehydrating effect. Developed a dry mix recipe that can serve as a basic development, low-calorie sweet products for catering and has a variance of use of lactic and succinic acids, depending on the flavor characteristics of the raw materials used and its corrective ability.

«Man is what he eats,» these words belong to the great Pythagoras. He meant by these words the connection of the origin of consumed food with the spiritual development of man. In fact, a lot depends on the nature of nutrition, the quality of food and, of course, on the degree of its perception by the body. Digestion process begins not in the stomach, but directly in the oral cavity as a result of mechanical processing of products with teeth and under the influence of the secretion of the salivary glands. That is why healthy teeth are the key to the normal functioning of the whole organism — people should start taking care of their teeth from the early childhood and dentists, who are far from being beloved by everybody and are often carelessly evaded, are called upon to help keep the teeth healthy.

Introduction. High density of oil-producing and refining facilities in certain areas of Bashkortostan significantly affects the environment including ambient air quality in residential areas. Materials and methods. We analyzed concentrations of airborne toxicants (sulfur and nitrogen oxides, nitrogen and carbon oxides, hydrogen sulfide, ammonia, xylenes, toluene, phenol and total suspended particles) and population health status in the cities of Ufa, Sterlitamak, Salavat, Blagoveshchensk, and the Tuymazinsky District in 2007–2016. Pearson's correlation coefficients (r) were used to establish possible relationships between medico-demographic indicators and air pollution. Results. Republican fuel and energy enterprises contributed the most to local air pollution levels. Gross emissions from such enterprises as Bashneft-Ufaneftekhim and Bashneft-Navoil reached 43.69–49.77 thousand tons of pollutants per year. The levels of some air pollutants exceeded their maximum permissible concentrations. Elevated concentrations of ammonia, total suspended particles, nitrogen dioxide, and carbon monoxide were registered most frequently. High rates of congenital abnormalities, respiratory diseases in infants (aged 0-1), general mortality and morbidity of the population were observed in some oil-producing and refining areas. The correlation analysis proved the relationship between the concentration of carbon monoxide and general disease rates in adults based on hospital admissions (r = 0.898), general incidence rates in children (r = 0.957), and blood disease rates in infants (r = 0.821). Respiratory diseases in children correlated with nitrogen dioxide emission levels (r = 0.899). Conclusions. Further development of oil-producing, petrochemical and oil-refining industries should be carried out taking into account socio-economic living conditions of the population.
