Znaczenie logowizualności dla odbiorcy. Logowizualność w transmisjach wydarzeń sportowych
Authors: Krzeczewski Kacper
Published: February 2025

Celem artykułu jest określenie funkcji, jakie pełni logowizualność w transmisjach wydarzeń sportowych oraz rozważenie jej znaczenia dla odbiorców tych przekazów. Zjawisko logowizualności należy rozumieć jako występowanie słowa pisanego w dyskursie telewizyjnym lub prościej – napisy i infografiki wzbogacające przekaz telewizyjny oraz w niektórych przypadkach również internetowy, mające na celu ułatwienie widzowi odbioru danego programu. Skupię się przede wszystkim na oddziaływaniu na odbiorców napisów i ikon (tzw. przekazów ikoniczno-werbalnych) wzbogacających obraz i dźwięk. Rozpocznę od omówienia sytuacji komunikacyjnych, w ramach których logowizualność jest wykorzystywana w telewizji na co dzień, co połączę z przedstawieniem dotychczasowego, niestety wciąż skromnego, stanu badań tego zjawiska. Następnie przejdę do głównego tematu i skoncentruję się na znaczeniu logowizualności dla odbiorców w transmisjach wydarzeń sportowych na przykładach wybranych dyscyplin (m.in. skoki narciarskie, piłka nożna czy żużel). Określę, jakie funkcje pełni ona w transmisjach wydarzeń sportowych (poszukam funkcji wspólnych dla wszystkich dyscyplin, jak i charakterystycznych dla wybranych sportów). Wykażę, że oglądanie zawodów sportowych w telewizji bez logowizualności byłoby bardzo utrudnione lub nawet niemożliwe i że jest ona pomocna w niwelowaniu nierówności społecznych osób głuchych i niedosłyszących. Odpowiem też na pytanie badawcze – dlaczego logowizualność jest niezbędnym elementem w transmisjach wydarzeń sportowych.
Hipertekst jako rzeczywistość. Komunikacja i język w polskich i niemieckich mikronacjach – zarys pracy doktorskiej
Authors: Bierzyński Zbigniew
Published: February 2025

Niniejszy artykuł prezentuje koncepcję pracy doktorskiej, której przedmiotem są polsko- i niemieckojęzyczne mikronacje – wirtualne państwa symulujące społeczeństwo i politykę w Internecie. Fenomen mikronacji pozostawał dotychczas w sferze zainteresowań socjologii, antropologii i nauk o komunikacji, choć stwarza również ciekawe możliwości dla badań tekstologicznych i lingwistycznych. Główna teza stawiana w proponowanej pracy brzmi, że hipertekst stanowi rzeczywistość mikronacji, ponieważ jednoczy w sobie zarówno znak, jak i jego materię w przeciwieństwie do świata realnego. Ponadto autor proponuje bliższe przyjrzenie się komunikacji, strukturze i multimodalnym środkom budującym wirtualną społeczność z perspektywy porównawczej, stawiając pytanie o typologię polskich i niemieckich mikronacji oraz ich komponenty kulturowe. Dodatkowo artykuł zwraca uwagę na powstającą w niemieckiej lingwistyce tekstu nową subdyscyplinę – lingwistykę obrazu (niem. Bildlinguistik) oraz nikłe zainteresowanie polskich tekstologów fenomenem hipertekstu, multimodalności i relacji między obrazem, a tekstem.

Benefiting from the basic characteristics, such as complex composition, high configurational entropy and local distortion, multi-principal element alloys offer a fruitful playground for creating diverse heterostructures. Laser-based techniques such as laser surface treatment and laser additive manufacturing provide facile solutions with advantages such as high-energy density, rapid solidification rate, and precise control over processed zones and shapes, making them promising for the advancement of heterostructured multi-principal-element alloys. This review primarily highlights the nanoscale microstructural characteristics of various heterostructured multi-principal element alloys fabricated by laser-based techniques, along with their enhanced mechanical properties and other relevant service attributes. Moreover, it sheds light on the challenges and opportunities in harmonizing microstructural features to optimize the mechanical behavior of heterostructured multi-principal element alloys for industrial applications.
Short-Term Costs and Long-Term Benefits of Environmental, Social, and Governance Performance on Corporate Credit Ratings
Authors: Ererdi Ertunç , Güneren Genç Elif
Published: February 2025

ESG (Environmental, Social and Corporate Governance) criteria are becoming increasingly important for companies to activate risk management and create long-term value within the framework of issues such as environmental concerns, expectations, reporting obligations, circular economy, regulatory compliance and investment demands. This study aims to explain how ESG scores and a company's financial performance affect credit risk. A company's ESG performance plays an important role in determining its credit score, which is directly reflected in its financial success and risk profile, and in strategic decision-making processes for investors and policy makers. The study determined that the balance between ESG performance and credit scores should be well understood, especially that high ESG scores may not always mean low financial risk, and that the long-term benefits of ESG investments should be well understood, as they will increase short-term costs.

Published: February 2025

This study investigates the catalytic performance of synthesized Pd/NiO nanoparticles (NPs) and the influence of oxidant-assisted advanced oxidation processes (AOPs) on the degradation of Congo red (CR), a model azo dye and a hazardous organic contaminant in water. Pd/NiO NPs are successfully synthesized via chemical coprecipitation and characterized using X-ray diffraction, transmission electron microscopy, scanning electron microscopy with energy-dispersive X-ray analysis, ultraviolet–visible (UV–Vis) spectroscopy, and the Brunauer–Emmett–Teller technique. These characterization techniques confirm the successful synthesis of Pd/NiO NPs. The photocatalytic degradation of CR dye under visible light irradiation is assessed using Pd/NiO NPs. The influence of various reaction conditions, including pH, irradiation time, catalyst dosage, and initial dye concentration, on the degradation process is studied. Pd/NiO NPs demonstrate exceptional performance in degrading CR dye, with degradation kinetics following a pseudo-first-order model. Additionally, the combined effects of hydrogen peroxide (H2O2) and persulfate (S2O82−) on photocatalytic efficiency are explored. The addition of these oxidants significantly enhances degradation, achieving 89.7% and 94.1% removal, respectively.

Authors: Ogbodo Stephen Chukwuma , Damba Joseph Junior , Olaoye Omotayo , Ofili Divine-Favour Chichenim , Ngwu Adaeze Augustina
Published: February 2025

Background: During the coronavirus disease 2019 (COVID-19) pandemic, the emergence of the Omicron SARS-CoV2 variant raised concerns about reduction in vaccine effectiveness due to its higher transmissibility. Thus, using ecologic data, we assessed the population-level impact of COVID-19 vaccination coverage on COVID-19 transmission and mortality, during the period of Omicron dominance globally. Subject and methods: We used a longitudinal dataset of 110 countries over 16 months (January 2022 to April 2023). Applying random-effects regression models, we assessed the effect of monthly full vaccination coverage on the rates of newly confirmed COVID-19 cases and deaths, adjusting for country characteristics. We obtained the data from open-access databases, including the World Health Organization (WHO) COVID-19 Dashboard and the Oxford COVID-19 Government Response Tracker. Results: On average, each 1% point increase in full vaccination coverage was associated with a 1.4% reduction (95% confidence interval (CI): 0.1%–2.8%, p = 0.035) in the rate of new cases and a 5% reduction (95% CI: 3.6%–6.4%, p < 0.001) in the rate of deaths. This protective effect of vaccination was graded across the levels of vaccination coverage: compared to countries with <50% vaccination coverage, those with coverages of 50%–59%, 60%–69%, 70%–79%, and ≥80% had 20.5% (95% CI: –16.4%–45.7%), 53.8% (22.6%–72.5%), 54.3% (15.5%–75.3%), and 69.6% (38.7%–84.9%) lower rates of new cases, respectively, on average. Conclusions: Our findings suggest an important role of vaccination in mitigating the impact of pandemics, particularly despite the emergence of highly transmissible variants like Omicron.

Authors: Mudarra-García Natalia , Roque-Rojas Fernando , Izquierdo-Izquierdo Visitación , García-Sánchez Francisco Javier
Published: February 2025

Background: Prehabilitation programs improve patients' functional capacity before surgery by enhancing physical activity, nutrition, and psychological well-being, thereby reducing postoperative complications, hospital stays, and readmissions. We propose a centralized model led by an advanced practice nurse and internist to minimize consultations and reduce costs.
Methods: We studied 211 patients in a tertiary hospital in Madrid, with 135 enrolled in the centralized prehabilitation program and 76 in standard care (control). We compared complications, hospital stays, blood transfusions, and consultations, estimating costs using public pricing from Madrid's healthcare authorities.
Results: The centralized model significantly reduced blood transfusions (p=0.014), postoperative complications (p<0.001), and hospital stays (p=0.004), leading to annual savings of €593,453.00.
Conclusions: A centralized surgical prehabilitation model decreases complications, hospital stays, readmissions, and consultations compared to standard care, significantly reducing healthcare costs.

Published: February 2025

This study proposes an innovative methodology that combines experimental microCT imaging with Monte Carlo irradiation simulations using the PENELOPE code aimed at enabling detailed analyses of different features involved in the irradiation processes along with elemental mapping, as required for X-ray fluorescence imaging of in vivo samples. By examining the relationship between signal-to-noise ratio (SNR) and absorbed dose (D), a mathematical approach was proposed to determine critical points where their rates of change are equal. Thus, allowing to identify optimal concentrations of gold dispersions to the specific simulated system of interest, where the signal quality efficiently improves as weighted in relation to the absorbed dose. The proposed methodology has been applied to a typical small animal (rat) microCT that was further used by the computationally implemented model to infuse the animal kidneys by different amounts of gold. For the K_(α_1 ), K_(α_2 ), and K_(β_1 ) lines, these critical concentrations were found to be 0.78 %, 1.32 %, and 0.32 % w/w, respectively, while no such behavior was identified for the K_(β_2 ) line under the given configuration considered as a representative/typical small animal infused with Au-based agents. The obtained results highlight the methodology's ability to optimize the balance between the absorbed dose and corresponding SNR, obtaining high-quality images without compromising in vivo samples due to excessive radiation exposure. Moreover, the proposed methodology provides high-resolution structural imaging and detailed elemental mapping, facilitating the analysis of detection limits along with the overall system performance. These findings confirm the robustness and reliability of the approach, offering a valuable tool for refining X-ray spectroscopy imaging processes and advancing X-ray fluorescence-based tomography techniques.

Published: February 2025

End-stage chronic kidney disease (CKD) and its treatment by hemodialysis represent a public health issue especially in Morocco. This study aimed to assess the impact of chronic renal failure on oral health in patients undergoing renal dialysis. A cross-sectional study was conducted among patients undergoing dialysis. The variables recorded were DMFT index and pH salivary. The correlation between oral health and the duration of dialysis was assessed. A total of 46 adult hemodialysis was evaluated, among them 52.2% were males, the mean age was 58.72 ± 12.4 years. All the patients in the sample underwent three dialysis sessions per week. Half of the patients brushed their teeth once a day. The average DMF-T index was 15.41 ± 6.04. Xerostomia was noted in 84.8% of the sample. This health situation analysis showed that dental care of the dialysis patients was not favorable, highlighting a great need for dental treatment. CKD cases should be made aware of the oral problems and their potential effect on overall health. A multidisciplinary approach with the involvement of different specialties is recommended.

Authors: Vrinceanu Bogdan Petru , Serban Florentin
Published: February 2025

This study explores the use of Shannon entropy as a filtering mechanism to enhance the trading signals produced by the LVQ (Learning Vector Quantization) machine learning algorithm in algorithmic trading. The integration of Shannon entropy aims to improve trade entry accuracy by reducing market noise and identifying stronger trends. A trading bot was developed and tested on Bitcoin using a three-minute timeframe on the TradingView platform, with backtesting conducted from February 1 to February 18, 2025. The fully automated strategy used 100% of available capital per trade, reinvesting profits for compounding. Positions were closed when an opposite signal was generated. A comparative analysis revealed that incorporating Shannon entropy outperformed a baseline strategy. These findings demonstrate that entropy-based filtering improves trade selection and profitability by reducing market noise and focusing on reliable trends, suggesting its potential for broader application in algorithmic trading.

Our results revealed seven polymorphisms in the RalGDS gene, including insertions, deletions, and frameshift mutations. These variations may significantly alter the protein structure and function of RalGDS, potentially influencing its role in Ral GTPase-mediated signaling pathways. This work provides foundational insights into the genetic diversity of porcine RalGDS and its implications for pig physiology and economically important traits.
Porcupine O-Acyltransferase (PORCN): Time Behavioural Study of 3rd Order Combinations in WNT3A Stimulated HEK 293 Cells
Authors: Sinha Shriprakash
Published: February 2025

PORCN belongs to the family of membrane bound O-acyl transferase (MBOAT). MBOAT members contain multiple transmembrane domains and carry two conserved residues, a conserved histidine (His) embedded in a hydrophobic stretch of residues and an asparagine (Asn) or histidine within a more hydrophilic region some 30-50 residues upstream. It can add palmitoleate groups to WNT proteins that is necessary for WNT ligand secretion. Gujral and MacBeath [1] provides a quantitative, and dynamic study of WNT3A-mediated stimulation of HEK 293 cells, where they record time based expression profiles of several response genes which correlated significantly with proliferation and migration. By monitoring the dynamics of gene expression using self-organizing maps, they identified clusters of genes that exhibit similar expression dynamics and uncovered previously unrecognized positive and negative feedback loops. However, their study depicts/uses singular measurements of individual gene expression at different time snapshots/points to infer the system wide analysis of the pathway. At any particular time point, it is often the case that genes are working synergistically in combinations, even though their expression measurements are singular in nature. Here, I • enumerate and rank all 2415 PORCN related 3rd order combinations in a forest of 71C3 combinations using four different sensitivity methods; • show the conserved rank- ings for PORCN-X-X combinations, which point to existence of biological synergy of some of these combinations across the different sensitivity methods; and • study the behaviour of some of these combinations related to WNT3A response genes that are ranked by the machine learning search engine (Sinha [2]) in time. Patterns of combinations emerge, some of which have been tested in wet lab, while others require further wet lab analysis.
A Comprehensive review on the Role of PM2.5 in Modulating Transplant Immunity and Graft Survival
Authors: Malik Muhammad Adil
Published: February 2025

Organ transplantation is an indispensable therapeutic approach for patients experiencing end-stage organ failure. Despite ongoing advancements and refinements in immunosuppressive therapies aimed at mitigating graft rejection and enhancing graft longevity, environmental influences including particulate matter 2.5 (PM2.5) have emerged as significant determinants of post-transplant health. PM2.5, a prevalent environmental contaminant, is particularly concerning due to its widespread presence and detrimental biological effects. Notably, the living environment of transplant recipients further exacerbates the complexity of post-transplant outcomes. Evaluating findings from recent investigations, this review delves into the influence of PM2.5 exposure on the immune system. The findings identify its capacity to provoke systemic inflammation, disrupt cytokine profiles, and compromise immune tolerance mechanisms. Such immune dysfunction poses direct risks to graft integrity, with potential implications for both graft health and the prospects of achieving long-term graft survival in affected patients.

This work presents the Transfer-Matrix Method as a mathematical approach for the calculus of different structures that can be discretized into elements, using an iterative calculation for future applications in vehicle industry. Plate calculus is important in construction, in medicine, in orthodontics and in many other fields too. This work is original and new. The plate is discretized along its length in unitary beams, which have the width of the rectangular plate. The unitary beam can also be discretized into parts. As applications, they are studied long rectangular plates, embedded on the two long borders and charged with a vertical uniform load that acts on a line parallel to the long borders. It is associated with each side a state vector. For each of the four cases studied, a matrix relationship was written for some side, based on a transfer matrix, the state vector corresponding to origin side and the vector due to the action of external forces acting to the considered side. After, it is possible to calculate all the state vectors for all sides of the unity beam. Now, the efforts, deformations and stress can be calculated in any section of the beam, respectively for the long rectangular plate. This calculus will serve as calculus of resistance for different pieces of components of vehicles.

Objective. To evaluate the clinical course of Wilson’s disease (WD) and the effectiveness of a scoring algorithm for diagnosis in children with early onset of the disease.
Patients and methods. Data from 85 case histories of children with WD observed at the National Medical Research Center for Children’s Health between 2012 and 2023 were retrospectively analyzed.
Results. Clinical and laboratory manifestations of WD at the age of 5 years and under were observed in 36 children. The mean ransaminase level was 128 U/L for alanine aminotransferase and 82 U/L for aspartate aminotransferase. Ceruloplasmin concentrations of <20 mg/dL were found in 32 (89%) patients, of which 47% had <10 mg/dL. Daily urinary copper excretion was determined in 33 of 36 children, and only 9 of them had levels of >100 mcg/day. In the group of children with normal urinary copper levels, the D-penicillamine challenge test was positive in 5 of 12 patients, with all 8 having copper concentrations of 50–100 mcg/dL. Liver copper levels were >250 mcg/g in 4 of 5 children. The most common pathogenic variant in the ATP7B gene was p. (His1069Gln), detected in 55% of children on 25 (34.7%) alleles. Using the Leipzig algorithm, the diagnosis of WD was made in 13 children without genetic testing, with the identification of Kayser-Fleischer rings, liver copper determination, and D-penicillamine challenge test being the decisive criteria.
Conclusion. The onset of WD at a young age is characterized by the absence of specific clinical and laboratory manifestations. Since some tests have low sensitivity in children and genetic testing is not available in certain cases, it is necessary to use a comprehensive approach to diagnosis.
Key words: Wilson’s disease, genetics, children, diagnosis, molecular genetic diagnosis, ATP7B

Multimodal Transformer for Heart Disease Classification Using Multiple Heart Sound Spectral Analyses and Clinical Metadata
Authors: Fujisawa Shintaro , Fukazawa Yusuke
Published: February 2025

This study proposes a multimodal fusion framework for heart disease classification that combines multiple spectral analyses of heart sounds with clinical metadata. Our framework integrates four complementary spectral analysis methods (Stockwell transform, bispectrum, mel-spectrogram, and power spectrum) using Vision Transformers. This spectral fusion is further enhanced by incorporating clinical metadata processed through Bio\_ClinicalBERT, enabling the capture of diagnostic insights from specialist physicians. Our framework achieved superior performance, with the model that fused both spectral features and clinical data reaching an accuracy of 0.881. This fusion model outperformed the individual spectral models, which had an accuracy of 0.831, by 6\%. Additionally, incorporating clinical metadata resulted in a 2.6\% improvement in accuracy compared to the model that fused only the four spectral features, which had an accuracy of 0.855. Through SHAP analysis, we discovered that our model excels at detecting right-heart abnormalities, which are often difficult to identify through traditional auscultation. Furthermore, we identified the Stockwell transform and mel-spectrogram as particularly influential features. The Stockwell transform's ability to localize both time and frequency information allowed our model to capture transient patterns crucial for detecting subtle heart sound abnormalities. Similarly, the mel-spectrogram, designed to mimic human auditory perception, excelled in highlighting frequency-related features commonly recognized by clinicians.

Beratung als Instrument der Kommunalaufsicht - eine Untersuchung unter besondererer Berücksichtigung des Einsatzes digitaler Anwendungen
Authors:   , Lunze Simone
Published: February 2025

Die vorliegende Dissertation befasst sich mit kommunalaufsichtlicher Beratung gegenüber den Gemeinden. Sie untersucht dabei insbesondere das Spannungsverhältnis, das Beratung als kooperativ ausgerichteter Wissensaustausch zu rechtsverbindlich wirkenden Maßnahmen erzeugt.
Ausgehend von den Gemeindeordnungen sowie verfassungsrechtlichen Vorgaben klärt die Arbeit zunächst den gesetzlichen Rahmen kommunalaufsichtlicher Beratung und befasst sich insbesondere mit der Frage, welche rechtlichen Implikationen sich bei der Nutzung digitaler Instrumente im Rahmen der Beratung ergeben.
Die Arbeit kommt zu dem Schluss, dass die Erteilung eines Hinweises oder Ratschlags – isoliert betrachtet – keine rechtsgültige Bindungswirkung erzeugt. Verfügt der Beratende zugleich über echte Eingriffsbefugnisse, kann allerdings eine Art Drohkulisse entstehen: Wenn die Aufsicht beispielsweise der Gemeinde signalisiert, dass die Genehmigung einer bestimmten Maßnahme abhängig sei von der Umsetzung der aufsichtlichen Ratschläge. Im dabei entstehenden „Schatten der Hierarchie“ gerät die durch Art. 28 Abs. 2 GG garantierte gemeindliche Eigenverantwortlichkeit schnell in Gefahr.
Vor diesem Hintergrund steckt die Untersuchung die rechtlichen Grenzen des informell-informatorischen Instruments der Beratung ab.

The article aims to develop a model of the parametric reliability of woodworking machine tools based on the criterion of technological accuracy. For this purpose, a mathematical model of the operating time of a woodworking machine to parametric failure was created using a scheme for changing the size of the workpiece. A linear differential equation characterizing the change in the dimensions for the machined workpiece was obtained based on the assumption of a linear relationship between the wear rate of the machine tool components and its technological accuracy. The differential equation was solved analytically using a Bernoulli approach. As a result, an analytical dependence was obtained for changing the workpiece dimensions. This dependence characterizes the technological accuracy of the machine tool during the overhaul period. The operating time intervals for woodworking machines between parametric failures were also evaluated. The probabilities of failure-free operation were calculated by considering the alpha probability density function for operating time intervals to failure of woodworking machine tools. Finally, it was found that the probability of failure-free operation of machine tools significantly depends on the time-depending parameter, which characterizes the relative durability of the machine tool.

Climate change and ocean acidification pose significant global challenges due to rising atmospheric CO2 levels, now nearing 424 ppm. Addressing this issue requires urgent solutions for CO2 mitigation. Electrochemical reduction of CO2 presents a promising pathway for CO2 conversion. Microfluidic electrolytic cells (MECs) offer advantages in mitigating reactor fouling and flooding. However, scaling up CO2 electroreduction to formic acid using MECs, particularly with 1-ethyl-3-methylimidazolium tetrafluoroborate [emim][BF4] as an ionic liquid electrolyte and Bi-Sn as a catalyst, remains underexplored. This study develops a scaled-up, steady-state numerical model for CO2 reduction to formic acid in MECs, employing a 70 % v/v [emim][BF4] electrolyte and a Bi-Sn catalyst at a 0.9:0.1 ratio. Key findings include achieving a current density of 275.8 mA/cm², a Faradaic efficiency of 89 %, and a CO2 conversion rate of 39.6 % at –16 V. These results underline the ionic liquid’s high CO2 solubility and conductivity. The model was also scaled to an n-cell stack using COMSOL Multiphysics, revealing a 2.2 % relative error between unit cell and stack configurations. This study demonstrates the feasibility of scaling MECs for efficient CO2 reduction.

Growing current demand for new water supply sources determines the need to search for new sources of groundwater. Since well drilling is expensive and environmentally risky, it is becoming relevant to use geophysical methods, in particular electrical exploration. Electrical resistivity tomography allows a detailed study of geological structure and properties of aquifers, but there are no clear recommendations for conducting electrical resistivity tomography studies when searching for groundwater in various geological conditions. To improve the accuracy and efficiency of geophysical works, it is proposed to perform mathematical modeling of electrical resistivity tomography data, which allows to assess the method sensitivity and possible measurement errors as well as to ensure the most accurate results. The purpose of the conducted study is to develop an optimal technique for groundwater exploration using electrical resistivity tomography in the conditions of permafrost distribution in the Bodaibo district. The technique takes into consideration possible groundwater occurrence conditions and includes mathematical modeling to assess the impact of permafrost on the data obtained. Numerical modeling has proved the efficiency of the method in permafrost areas. Water-flooded fractured areas characterized by low values of specific electrical resistance have been reliably identified in all obtained modeling data. The results of solving direct and inverse problems of electrical exploration compared with the data of production works performed in 2020 in the Republic of Buryatia and in 2022 in the Irkutsk region have shown that electrical tomographic studies, which were successfully confirmed by drilling, make it possible to identify a productive water-flooded horizon with a very high degree of confidence.

The purpose of the research is to study the geoecological situation in the urban-type settlement of Vershino-Darasunsky (Transbaikal region, Russia), where a plant producing white arsenic for chemical warfare agents operated from the 1930s until 1973. Reclamation did not follow the shutdown of the plant, which causes a serious environmental threat not eliminated with past decades due to the low priority of this territory in the register of objects of accumulated environ mental damage. The authors consider the current facility assessment, which is based on data on the insignificant area in the boundaries of the former industrial site of the plant, to be critically underestimated. The latter is the main reason for the failure of a number of attempts made by executive authorities for years to launch the development of this site reclamation project. The conducted research is an illustrative case study from real Russian environmental practice and may be of interest to academic and professional communities. The study includes the analysis of the relevant regulatory framework for the assessment and elimination of the objects of accumulated environmental damage as well as the adopted method ology to carry out the assessment. A complex of field and laboratory studies was conducted on the area of 16.5 km2, more than 150 soil samples were taken. The article presents the first results of geochemical soil studies, according to which it is not only contaminated industrial site, but also the entire studied territory, which has changed its physico-chemical parameters over many decades are the sources of negative impact on environmental objects. Anomalies of arsenic and heavy metals exceeding the maximum permissible and approximate permissible concentrations by hundreds and thousands of times have been detected, and they are localized not only in the area of the known facility of accumulated environmental damage, but also in several other places without currently visible sources of man-made impacts. The results obtained made it possible to declare the need to expand the reclamation area beyond the immediate territory of the former plant. In accordance with the accepted criteria, the environmental hazard indicator has been recalculated and the need to change the reclamation prioritization of this facility has been justified. Moreover, based on the existing regulatory framework, recommendations are given for further assessment of the impact of objects of accumulated environmental damage on the lives and health of citizens.
