Authors: Geregey Andrey M. , Shuporin Evgeny S. , Fateev Ivan V.
Published: December 2020

Today, there are personal protective equipment, which due to their weight and size characteristics and design features can aggravate professional activity. This is characterized by an increase in the load on several major systems of the employee's body, including the cardiorespiratory system, which can cause the development of occupational pathology. The study of the functions of the cardiorespiratory system of humans in the process of his work is an important task in biomedical tests such as PPE, aggravating their professional activities and future means of individual protection from heavy labor and industrial exoskeletons. The aim of the study is to determine the possibility of using ergospirometry for the physiological assessment of personal protective equipment and industrial exoskeletons. Main part. In medical practice and high-performance sports, ergospirometry is considered the "gold standard" for functional assessment of the cardiorespiratory system. There are very few studies showing the use of ergospirometry for the purpose of physiological assessment of personal protective equipment. Results of research works in which ergospirometry was used in medicine, sports, as well as on the physiological and hygienic assessment of combat equipment, various types of personal protective equipment, including new promising personal protective equipment of the musculoskeletal system-industrial exoskeletons. The use of ergospirometry made it possible to register the main indicators of the human cardiorespiratory system both in field and laboratory conditions and allowed forming an objective conclusion about the dynamics of the degree of stress of the human cardiorespiratory system when using personal protective equipment and industrial exoskeletons with various weight and size characteristics. Thus, the use of ergospirometry both in isolation and in combination with other methods allows us to solve problems related to biomedical testing of personal protective equipment and industrial exoskeletons.

Published: December 2020

Introduction. Issues of preserving the health and saving of the Russian population are important in the development of state programs. One of the main sources of population growth, as well as the preservation of the labor potential of our country, is the reduction of the death rate of the working - age population. The aim of the study was to analyze the mortality of the population in the age groups 15-59 years and 15-64 years for men and 15-54 years and 15-59 years for women in Russia in comparison with the countries of the European Union (EU-28). Materials and methods. Mortality was studied based on data from Rosstat and the WHO Mortality Database and the Human Mortality Database. Age-standardized mortality rates were calculated for Russia in 2018 and the EU-28 countries in 2017 (European standard, revised 2013). Results. Comparative analysis of the standardized mortality rates of the population 15 to 59 years and 15-64 years for men and 15-54 years of age and 15-59 years of age showed a significant gap between Russia and the EU-28. Differences in mortality among men in comparison with the EU-28 in the age group of 15-59 years was 3.1 times, and in the age group 15-64 years - by 2.8 times. In women aged 15-54 years, the excess was 2.5 times, and in those aged 15-59 years - 2.2 times. Conclusions. Thus, the analysis of modern data on the mortality of the male (aged 15-59 and 15-64 years) and female (aged 15-54 and 15-59 years) populations indicated that negative trends persist in Russia's lagging behind the European Union countries.
Modern aspects of professional cancer treatment: prospects for the use of medical ozone in the correction of free radical homeostasis
Authors: Zhukova Evgeniya S. , Kashina Anna Yu. , Irkaeva Anastasiya M.
Published: December 2020

Introduction. The well-known features of oncogenesis make it possible to assume the prospects of medical ozone as part of a comprehensive health-saving therapy for professional oncopathologies. Due to the risk of stimulating the proliferation of tumor cells, research on the search for optimal modes of ozone exposure is relevant. The aim of the study was to evaluate the possibility of using ozonated saline solution (OSS) as part of complex antitumor therapy in an experiment. Materials and methods. The effect of OSS with different concentrations of ozone in the ozone-oxygen mixture on the content of hemoglobin, active products of thiobarbituric acid (TBA) of lipid peroxidation (LP), the degree of oxidative modification of proteins, and the activity of superoxide dismutase and catalase in blood, liver, spleen, and tumor tissues was studied in Mature rats with normal and transplanted cholangiocellular carcinoma. Results. The course effect of the OSS did not have statistically significant changes in the studied biochemical parameters under the conditions of the physiological norm in the experiment. Exposure to OSS during oncogenesis led to a decrease in the content of TBA-active LP products in the liver by more than 30%. Conclusions. Course exposure to OSS with an ozone concentration in an ozone-oxygen mixture of 400 micrograms/l may be promising for the correction of free radical homeostasis as part of complex antitumor therapy, including in oncogenesis due to occupational factors.
Critical analysis of the results of sanitary and hygienic characteristics of working conditions for pilots of civil aviation aircraft
Authors: Immel O. V. , Fomina M. E.
Published: December 2020

Introduction. Discrepancies in the regulatory documents regulating the compilation of sanitary and hygienic characteristics (SGC) of pilots' working conditions, the lack of a complex of laboratory and instrumental studies conducted at the workplace and, as a result, incomplete and unreliable compilation of SGC, lead to difficulties in establishing the connection between the disease and the pilot's profession. The aim of study is to conduct a critical analysis of the quality of the preparation of the CGS, followed by identifying the main violations of the requirements of regulatory documents in the design of the CGS. Materials and methods. A retrospective analysis of the quality of registration of the SGC of pilots with an established diagnosis of occupational disease was performed. Results. Contradictions in the current legal acts are established and discrepancies in methods for assessing the normalized indicators of working conditions of pilots are revealed. The data obtained indicate that the main requirements for filling out the SGC, justified by the specifics of the working conditions of pilots, are not taken into account when they are issued; when evaluating the measurement results, non-current regulatory documents are used, or documents that do not regulate the working conditions of civil aviation pilots. Conclusions. To improve the quality of registration of the SGC, it is necessary to update the current regulations and develop guidelines with the establishment of the form of the SGC for working conditions of civil aviation flight personnel in case of suspected occupational disease.
Practical aspects of occupational risk assessment from industrial noise exposure
Authors: Martin Sergey V. , Kudryashov Ivan N. , Ivashchenko Maksim A.
Published: December 2020

Introduction. Today, there is an active application of the occupational risk assessment approach in hygiene practice. In particular, the employer is required to assess the risk of exceeding the production noise limit. The aim of study is to identify issues related to the performance of work on the assessment of occupational risk from noise exposure, based on practical experience. Materials and methods. The assessment of the probability of adverse effects on the health of specific individuals employed in more than a thousand jobs in various branches of Russian industry allows us to identify a number of practical problems. Results. The main problem is the lack of information about the levels of impacting noise that is suitable for constructing subsequent stages of research. One option is the absence of annual monitoring of noise with possible variability in the level of exposure in dynamics. Also, when performing control, there is the use of measuring instruments that do not meet the requirements for ensuring the uniformity of measurements. Often, we are faced with the lack of a fixed identification of workplaces that allows us to track the levels of impacting noise in dynamics. The priority was to support the risk assessment work by conducting control measurements of noise levels with the priority use of personal noise meters to minimize the contribution of uncertainties. Conclusions. The analysis of international experience shows the need to introduce new approaches to monitoring noise levels and the implemented effects of its impact on the part of the hearing organ, including monitoring the accumulated doses, the introduction of a" noise professional route", mandatory audiometry when hiring and annual monitoring of the dynamics of hearing changes; evaluating the effectiveness of the used personal hearing protection equipment (PHPE) in real production conditions.
Main approaches to prevention of health disorders in workers in contact with physical factors
Authors: Melentyev Andrey V.
Published: December 2020

Introduction. One of the leading causes of occupational health loss, especially in mining and machine-building enterprises, is the combined impact of industrial noise and vibration. The wide prevalence of cardiovascular diseases is one of the most important medical and social problems, due to persistent disability and high mortality, bringing prevention of health disorders to the first place as the basis for preserving labor longevity. The aim of study is to identify the main approaches aimed at preventing health problems in workers who come into contact with vibration and noise at mining and machine-building enterprises. Materials and methods. A survey and survey of 296 industrial workers was conducted. Group 1 (160 people) included men who were exposed to noise and vibration factors above the maximum permissible levels, group 2 consisted of 136 men who did not have direct contact with noise and vibration generating equipment. When conducting an in-depth laboratory and instrumental examination in a hospital setting, all workers additionally calculated the level of cardiovascular risk on the SCORE scale. Statistical analysis was performed using the software package "Statistica 6.0". Results. It is determined that the priority adverse factors of the working environment in production are noise and vibration. It has been shown that individuals who come into contact with these factors are more likely to detect violations of lipid metabolism and endothelial function, have a higher average heart rate and systolic blood pressure, and have an increased risk of developing cardiovascular diseases. Conclusions. Taking into account the obtained results of the proposed diagnostic approaches aimed at the prevention of health disorders among workers of industrial enterprises. If employees are found to have an increased cardiovascular risk, it is necessary to conduct a more in-depth examination and timely medical and preventive measures.

Published: December 2020

Our CSR (corporate social responsibility) activities and innovation initiatives complementary? From a resource-based perspective, managers would develop CSR and Innovation's business strategy to create heterogeneity and build sustainable competitive advantage. Based on instrumental theories, CSR is a means for firms to accomplish economic output; therefore, CSR may lead or utilize Innovation for this purpose. As CSR is getting more attention, and Innovation is important for a firm's growth, to find the interaction effect of CSR and Innovation is getting more important. However, to our limited knowledge, there are fewer studies and discussions about the topic. Thus, the research would develop a new analysis model to study the topic. Regarding the methodology, four questions are designed to be answered, and two categories of the dataset are collected. These questions are: (1) Does CSR have an impact on firms' performance? (2) Does long-term investment have an impact on the firm's performance? (3) Does R&D have an impact on a firm's performance? (4) How does the interaction of CSR and Innovation investment impact on firm's performance? The datasets include finical data and ESG (Environmental, Social, and Governance) ratings of firms. We would start the research from a typical industry in a country and look forward to a future extension to multiple industries across countries. We select Taiwan's electronics industry due to its important role in the global market, its leading position in Innovation, and its great efforts on CSR. So far, the research is still in progress. We would share the results, finding, and conclusion of the preliminary analysis. I look forward to your valuable comments for us to improve the analysis model and to find opportunities for further studies in other industries or other countries.

Authors: Lii Yuan-Shuh , Lin Chieh Lun
Published: December 2020

This study presents empirical evidence on the effect of product-line prices and competitors' prices on consumers' price judgments as well as on consumers' use of advertised reference price (A.R.P.) as reference across two product categories. Using a 2 x 2 x 2 factorial design experiment, the findings indicated that consumers did not consider product line prices as an important reference. Competitors' prices were found to be a significant reference in the case of frequently purchased product categories. The moderating roles of product line prices and competitors' prices in reference price advertisements were not found. A.R.P. still exerted the greatest influence on consumers' evaluations of a promotional offer across two product categories.

On the Emergence of Russian-South African Business Links. Allan Bowe, Faberge’s Business Partner
Authors: Gorelik Boris
Published: December 2020

Allan Bowe, a Cape-born entrepreneur in the Russian Empire, has not been mentioned in literature on the history of Russian-South African contacts. However, his long business partnership with Carl Fabergé should be considered in this context, primarily because it took place when Russia and the territories that are now part of South Africa, apparently, had no trade relations yet.

Henry Allan Talbot Bowe, known in Russia as “Allan Andreyevich Bo”, can be rightfully regarded as a South African. He spent his childhood and youth in the Cape Colony, mostly in Namaqualand, a region dominated by native speakers of languages that had originated in Africa.

Contrary to the established notion that “the exquisite artistic taste and amazing energy of Carl Fabergé” were the main reason for the international success of this business, it owed much to the work of his companion, A. Bowe. The latter contributed to the development of the largest jewellery company in the Russian Empire and its international reputation in the 1880s–1890s. As a founder and co-owner of the Fabergé Moscow branch, he organised and managed the largest jewellery factory in the country.

Bowe also expanded the company’s presence abroad by establishing the London branch (as a joint owner with Fabergé) and building up clientele securing orders for bespoke jewellery pieces in Europe, Southeast Asia and North America.

The first arrival of Bowe in Russia was almost accidental, but he became deeply involved in the business life of Moscow – so much so that he returned to that city after he had dissolved his partnership with Fabergé.

Being possibly the first successful South African-born entrepreneur in Russia, he deserves a prominent place in the history of relations between our countries. It implies that the emergence of Russian-South African business links can be traced to the 1880s, when Bowe started his business in Moscow.
Determinants and Consequences of Population Trends in Sub-Saharan Africa
Authors: Ivanov Sergey
Published: December 2020

During the universal demographic transition, the traditional type of population reproduction, characterized by high mortality and high fertility, is transformed into a type of reproduction in which both components are at a low level. The demographic transition is not taking place in a social vacuum, but under the influence of many social factors, including the growth of education and economic development. Reducing child mortality is a sine qua non for changing reproductive behavior. Declines in mortality and fertility are usually separated by long periods when population growth is accelerating. The population explosion is fading away in most countries of Asia and Latin America because they have passed the main part of the demographic transition. In Africa, the decline in child mortality began later and is still in the incipient phase. As a result, fertility, although declining in recent decades in most countries, is declining slowly and remains high. The region as a whole is in the early stage of the demographic transition: the population is growing rapidly and it is not expected to stabilize until the end of the century. Most of the economic and social consequences of rapid population growth are negative. Their conceptualization takes place within the framework of the neo-Malthusian paradigm, which made it possible to substantiate demographic policy based on family planning programs that have proven their effectiveness in different regions of the world. The negative, and sometimes disastrous, consequences of rapid population growth are particularly pronounced in Africa. Anti-Malthusianism is less inclined towards scientific argumentation, and its main goal is not pragmatic solutions to problems, but ideological proclamations, although some anti-Malthusian concepts have positive potential. The concept of the demographic dividend, developed in recent decades, makes it possible to remove the contradictions between two opposing paradigms, since it shifts the emphasis from the negative consequences of rapid population growth to the positive consequences of changes in the population age structure during the demographic transition. The demographic transition in Africa needs to be accelerated, and policies are able to do this without relying on the impractical assumptions of fast economic growth. Three interrelated factors are critical: development of education, radical reduction in child mortality and strengthening of family planning programs.
Factors Influencing Generation Z Intention in Using FinTech Digital Payment Services
Authors: Aseng Andrew Christian
Published: December 2020

Many studies related to financial technology (FinTech), especially digital payment services, have been carried out. However, there is still a lack of studies that focus on Generation Z, especially their intention to use the service, while this generation is very familiar and is easily adaptable to new technologies. In addition, it is projected that this generation will contribute greatly to online transactions in Indonesia and even the world. For this reason, this study focuses on factors that can influence Generation Z’s intention to use digital payment services. There are five independent factors that will be tested, namely: culture, perceived security, performance expectancy, effort expectancy, and social influence. The research instrument was a questionnaire adopted from related literature, which was distributed online using the snowball and convenient sampling method. A total of 266 Generation Z people participated in this study. A descriptive statistic and multiple regression analysis were performed and found that simultaneously these five factors had a significant positive effect (Sig <.05) on the intention of Generation Z in using the service. This study concludes that service providers have to pay attention to these factors in attracting Generation Z.Keywords—digital payment services, financial technology, Generation Z

Do serial killer films have a CSI effect?
Authors: jennings ebony
Published: December 2020

Objectives: The aim of this study is to investigate if inaccurate portrayals in serial killer films create a similar effect to that of the CSI effect in audiences. This is because there is a lot of research showing the CSI effect in TV dramatizations of crime but if there is the same effect in film is virtually unexplored. This is important as it could increase peoples fear of crime and effect how they behave as part of a jury. Method: This study used a qualitative approach as it was underutilised in the previous literature. A questionnaire, which was an adaptation of Saelens, Sallis, Black and Chen (2002), was distributed using social media. This study also had ethical approval. The results were then analysed using thematic analysis. Results: 4 themes were identified: victims, perpetrators, safety and social policy. Conclusion: Findings mostly fit with the hypothesis (film had affected their perceived knowledge, potentially creating a CSI effect), apart from some variation within the data. There was no evidence of the expected affect on fear of crime but the results do still suggest there may be an effect on their behaviour as part of a jury. It is suggested that future studies use a bigger
MMP13 is differentially expressed and down-regulated in brain metastatic breast cancer.
Authors: Mamoor Shahan
Published: December 2020

Brain metastases are a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to discover genes associated with brain metastasis in patients with brain metastatic breast cancer. We found that the gene encoding the matrix metalloproteinase 13, MMP13, was among the genes most differentially expressed in the brain metastases of patients with brain metastatic breast cancer. MMP13 may be of relevance to the biology underlying metastasis to the brain in humans with metastatic breast cancer. MMP13 now joins MMP14, MMP11 and MMP2 among matrix metalloproteinases we have found to be differentially expressed and down-regulated in the brain metastases of humans with metastatic breast cancer (6-8).

From member creativity to team creativity? Team information elaboration as moderator of the additive and disjunctive models
Authors: Yuan Yingjie , van Knippenberg Daan
Published: December 2020

One of the most fundamental questions in team creativity research is the relationship between individual member creativity and team creativity. The two answers that team creativity research has advanced–teams are more creative when their average member creativity is higher (the additive model) and teams are more creative when their most creative member is more creative (the disjunctive model) are straightforward. Surprising, however, is that neither the additive model nor the disjunctive model is consistently supported, begging the question of what moderates the predictive power of these models. We address this question by integrating individual-to-team creativity models with team process research. We propose that team information elaboration is a key moderating variable, such that average member creativity is more positively related to team creativity with higher information elaboration, and the highest member creativity is more positively related to team creativity with lower information elaboration. A multi-source study of 60 sales teams (483 employees) in a Chinese bakery chain supported these hypotheses. In addition, the study did not support the prediction that the most creative member’s outgoing advice ties (as a conduit for the dissemination of ideas) would further moderate the joint effect of the highest individual creativity and team information elaboration on team creativity.
Timing in conversation is dynamically adjusted turn by turn in dyadic telephone conversations
Authors: Pouw Wim , Holler Judith
Published: December 2020

Conversational turn taking in human interaction is incredibly rapid. The timing mechanisms underpinning this behaviour have been heavily debated, including questions such as who is doing the timing. Similar to findings on rhythmic tapping to a metronome, we show that floor transfer offsets in telephone conversations are serially dependent, such that FTOs are lag-1 negatively autocorrelated. Finding dependence on a turn-by-turn basis (lag-1) rather than on the basis of two or more turns, suggests a counter-adjustment mechanism operating at the level of the dyad in FTOs during telephone conversations, rather than a more individualistic self-adjustment within speakers. This finding, if replicated, has major implications for models describing turn taking, and confirms the joint, dyadic nature of human conversational dynamics. Future research is needed to see how pervasive serial dependencies in FTOs are, such as for example in richer communicative face-to-face contexts where visual signals affect conversational timing.
Indian costumes through the ages – Insights into sartorial choices using mathematical biology
Authors: Raghavan Mohan , K Raghavendra M
Published: December 2020

Costumes of a civilization are studied as a means of understanding the people, their thinking, tastes and culture. This field has mostly taken a descriptive approach where features are analyzed, compared in detail to glean information about the epoch and culture. In this interdisciplinary study, we propose a novel numerical encoding of costumes based on the interaction of costumes with human anatomy. Using methods from machine classification on a set of costumes from ancient to contemporary periods, we show that costumes of different epochs and cultures are separable in the two dimensional principal component space. We use the Eigen costumes to analyze the immutable similarity in Indic costumes through the ages and the contrasting features between Indic and non-Indic. We further dwell into primary sources to demonstrate that these characteristic features of Indic costumes were very likely considered and deliberate choices in order to induce beneficial effects on prāṇa in specific, and achieve harmony in Yoga in general. We hope that this work will be a small first step for an alternate way of deriving insights into personal choices, societal trends and cultures using methods from life sciences and computation.

Due to the increase in demand for electric power and increasing population density in different regions, the application of underground cables has become widely used in transmission and distribution networks. In this paper, the thermal behavior of underground cables was studied numerically. Four types of underground cables were selected copper conductor cables with (95 mm2) and (240 mm2) and aluminum conductor cables (95mm2) and (240mm2), which are used in the power networks in Iraq. The study was carried out based on the conditions surrounding such as the ambient temperature, the thermal properties of the soil and the current capacity, its effect on the thermal behavior of the cables. The results of the numerical simulation showed that the surrounding factors and loading capacities have a direct effect on determining the temperature of the cable. In addition, the type and size of the conductor cable material have an effect on determining the current-carrying capacity of the cable where the conductor cable with a nominal cross-sectional area 240mm2 has a temperature higher than the conductor cable with nominal cross-sectional 95mm2by (8.96%) for the copper conductor and (13.68%) for the aluminum conductor at current 500A.

In this work, two-dimension incompressible laminar viscoelastic fluid flow in an expansion-contraction duct has been investigated numerically. The effect of expansion-contraction shape, Deborah number, Reynolds number, expansion ratio and contraction length on the flow field variables has been investigated. Four cases for the expansion-contraction duct configurations are tested, the first case is the expansion duct, the second case is the contraction-expansion duct, the third case is the triangular expansion-contraction duct and the fourth case is the two-side triangular expansion-contraction duct. The study investigated the effect of the parameters: Reynolds number (Re), Deborah number (De), contraction length and expansion ratio (ER) on the flow field variables (pressure, stresses and velocity).
    The FENE-P (Finitely Extensible Nonlinear Elastic in the Peterlin approximation) viscoelastic fluid model is chosen for the modeling of viscoelastic fluid flow. The code is written in Simply Fortran 2 computer language. Numerically the momentum equations and the FENE-P model equation are solved by using the finite volume method passed on the collocated grid arrangement by using the Rhie-Chow interpolation. The power low scheme is used for the convective terms in the momentum equations, the up-wind scheme is used in the convective terms in the FENE-P model equation and the TDMA algorithm is used to solve the algebraic equations.
   The results show that the expansion ratio when decreasing causes an increase in the stresses and the pressure for all the studied cases. Further, the contraction length increment playing a major effect on the increasing of the pressure. It is discovered that increasing contraction length by 50% causes an increase in the pressure by 50%. For Deborah number, the results show that Deborah number effects all variables in the flow field, where the stresses show increasing with the increasing of Deborah number at the expansion side of all the cases. Moreover, the pressure is also increased as Deborah number increase for all the cases.  The expansion duct it shows that increasing Deborah number from 0 to 1 causes an increase of 1.2% of the pressure, while for the contraction-expansion duct this percentage is increased. It is shown that increasing Deborah from 0 to 0.5 causes an increasing by 5% of the pressure. Furthermore, the effect of Deborah number on the recirculation zones is to shrink their size for all the cases.
   A comparison between the studied cases are presented and shows that the contraction-expansion duct has the maximum stresses and maximum required pressure, while the triangle contraction-expansion has the smallest required pressure. The limit of Deborah number gets to 1.2 in the expansion duct, while it is limited to 0.5 for the other cases.

Purpose: analysis of predicted water losses for evaporation from the water surface of the Sokolovskiy reservoir and ponds located on the river Kundryuch’ya, within the boundaries of the investigated site on the territory of the Russian Federation from Rebrikovka to the Sokolovskiy reservoir site and the annual distribution of evaporation depending on the percentage availability. An assessment of the possible impact of quantitative indicators of evaporation on the water supply of the river Kundryuch’ya and Sokolovskiy reservoir was made. Materials and methods: for calculating the amount of precipitation, evaporation and irretrievable losses from the water surface of reservoirs located in the basin of the river Kundryuch’ya upstream the Sokolovskiy reservoir section, the formulas for average long-term conditions, formulas for calculating the volumes of evaporation and nonrecoverable losses at P = 10, 25, 50 and 75 % of supply, as well as a contour map were used. The formulas used and the contour map were taken from the textbook by G. V. Zheleznyakov “Hydrology, Hydrometry and Flow Regulation”. Results: the values of monthly evaporation as a percentage of the annual amount, as well as layers and volumes of evaporation for the Sokolovskiy reservoir are given. It has been determined that the share of nonrecoverable losses from the Sokolovskiy reservoir is 0.87, from the rest of the water bodies is 0.13. The amount of nonrecoverable losses at different levels of availability range from 2.64 million m³ (10 %) to 1.85 million m³ (75 %). Conclusions. The research results served as a basis for making a decision on the liquidation or further operation of the existing water retaining structures. In view of the low values of nonrecoverable losses from water bodies, which have an insignificant effect on the quantitative indicators of runoff, the decision was made in favor of further operation.

Purpose: to determine the ecological and toxicological state of various types of chernozems in Rostov region by the content of mobile forms of heavy metals. Materials and methods. The studies were carried out on irrigated areas of Semikarakorsky, Matveevo-Kurgansky, Neklinovsky, Salsky, Veselovsky districts of Rostov region. The soils were sampled in layers of 0–20, 20–40 cm and analyzed using the method of measuring the mass fraction of mobile forms of metals by atomic absorption. Results. The content of mobile forms of the determined metals (zinc, lead, cadmium, nickel, copper) was not found to be higher than the maximum permissible concentration (MPC). The rows of the determined metals were constructed according to their share of the MPC in the 0–20 cm layer, which showed that cadmium (from 0.2 to 0.4 MPC), lead (from 0.05 to 0.12 MPC) and nickel (from 0.04 to 0.17 MPC) are closer to MPC in all chernozems of the studied regions of Rostov region. Pollutants were found in the chernozems of Salsk region in the smallest amount, except for copper (0.09 MPC). The content of copper in soils 0.04–0.35 mg/kg indicates its low and stable distribution in the studied soils, except for Veselovsky district, where the analysis showed values below the detection limit, which may indicate a lack of copper as a trace element. According to the soil grouping for ecological and toxicological assessment by the content of mobile forms of heavy metals, they belong to the 1st group, i.e. the soils contain pollutants below the MPC and are suitable for the cultivation of all agricultural crops. Conclusions. The ecological and toxicological state of soils of the surveyed areas by the content of mobile forms of zinc, lead, nickel, cadmium and copper is assessed as satisfactory.
