Opis:
Lubricated mechanical mechanisms operate under service conditions influenced by several environmental parameters, and their life times may be threatened due to inappropriate use or by the presence of solid contaminants. The objective of this work is to study the effect of three operating parameters, namely: rotational speed , load and kinematic viscosity in the presence of three sizes of solid contaminants , on the degradation of an EHL contact, to predict the ranges of effects that may lead to the damage of the contacting surfaces. In our investigation, anexperimental design of nine trials is used to combine four factors with three levels each to accomplish the experimental investigation. Artificial neural network regression and the desirability function were used for the interpretation and modelling of the responses, whichare: wear , arithmetic mean height , total profile height and maximum profile height . From these methods we observed that the sand grain sizes have a significant impact on the wear and the roughness , but that viscosity has the primary influence on the variation of the roughnesses and . We also found that the quality of the predicted models is very good, with overall determination coefficients of 2 learning = 0.9985 and 2 validation = 0.9996. Several levels of degradation depending on the operating conditions are predicted using the desirability function.

Opis:
W reakcji na katastrofę ekologiczną, do której doszło na Odrze latem 2022 r. kluczowe organy administracji publicznej odpowiedzialne za bezpieczeństwo obywateli długo pozostawały bierne i nie podejmowały koniecznych działań. Nie zapewniły skutecznego obiegu informacji oraz nie uruchomiły odpowiednich struktur zarządzania kryzysowego. W konsekwencji alerty ostrzegawcze i zakazy korzystania z rzeki skierowano do ludności z co najmniej kilkunastodniowym opóźnieniem. Kryzys na Odrze obnażył brak należytej troski państwa o dobry stan wód. Był to efekt wieloletnich zaniechań jego organów, błędnych działań, a także niewystarczających rozwiązań prawnych.
In summer 2022, the catchment area of the Odra River was affected by an ecological catastrophe the scope of which had been unprecedented. In the river, where water was contaminated along hundreds of kilometres, fish and other organisms, such as clams and freshwater snails, died in large numbers. At least 350 tonnes of poisoned fish were recovered from the Odra River and its tributaries. The results of the analyses conducted by researchers from the Institute of Marine and Environmental Sciences of the University of Szczecin and experts from non-governmental organisations, which were published at the end of 2023, showed beyond doubt that over 3 million fish died (1,650 tonnes, i.e. 60 percent of their biomass), as well as almost 90 percent of organisms involved in the river’s self-purification processes. Taking into account the scale of the catastrophe and its consequences, it was justified to evaluate the activities of the government administration bodies and state legal persons responsible for reacting on the situation, especially in the light of publicly voiced accusations of their idleness, especially during the first phase of the crisis. It was also important to present the conditions stemming from the actions taken, or negligence that led to idleness. The NIK’s audit focused on two areas: preparedness of the state structures and the circumstances that led to the ecological crisis in the Odra River, as well as the way state bodies reacted on the situation. The article presents the findings of this audit.

Opis:
The expansion of the electrical network necessitates the construction of new power plants and the extension of overhead and underground power transmission and distribution systems. However, underground power cables, such as XPLE 220 kV, can cause significant electromagnetic pollution, particularly in urban areas. This paper focuses on the evaluation and prediction of such magnetic emissions using analytical, numerical simulation (the finite element analysis), and experimental measurement. The paper aim is to minimize the magnetic emissions through the adjustment of the horizontal and vertical distances (x, y) of cables, serving as a technical solution. Additionally, the study investigated the impact of faults with varying magnitude and frequency, considering different loads and conditions. The simulation results indicate that several factors contribute to the escalation of magnetic pollution. These factors include a close proximity between cables, faults, and high current intensities.... However, as the distance between cables increases both horizontally and vertically, the strength of the magnetic field decreases, leading to a reduction in magnetic pollution. A comparison was carried out to assess the magnetic emissions of the underground cable, revealing a notable resemblance between the measured and calculated values. Ultimately, the validated simulation model serves as a valuable tool for evaluating, predicting, and mitigating electromagnetic pollution under different fault conditions and positions.

Celem badań była ocena jakości mikrobiologicznej powietrza trzech klatek schodowych w blokach mieszkalnych wielorodzinnych. Badano wpływ pory roku i temperatury na liczebność oraz bioróżnorodność mikroorganizmów w bioareozolu klatek schodowych. Wszystkie badania zostały wykonane za pomocą aeroskopu MAS-100 (Merck), metodą uderzeniową. Stwierdzono przekraczające normy stężenia promieniowców oraz gronkowców w powietrzu atmosferycznym oraz powietrzu wybranych klatek schodowych. Pora roku oraz temperatura powietrza mają wpływ na stężenie mikroorganizmów w powietrzu. Wiek budynku, dostępność światła oraz system wentylacji mogą mieć również wpływ na stężenie wskaźników czystości mikrobiologicznej powietrza.
The aim of the study was to assess the microbiological air quality in three staircases of multifamily residential buildings. The study examined influence of season and air temperature on the abundance and biodiversity of microorganisms in the bioaerosol of stairwells. All studies were conducted using an impact method with the MAS-100 aerosol sampler (Merck). Concentrations of actinomycetes and staphylococci in both atmospheric air and selected stairwells exceeded norms. Season and air temperature have an impact on microbial concentrations in the air. The age of the building, light availability and ventilation conditions were also identified as potential factors influencing the concentration of specific microbial groups in the bioaerosol.

Opis:
Olive mill wastewaters represent a severe environmental problem, especially in Mediterranean countries. Indeed, the treatment and recovery processes developed so far remain very limited and their cost is very high. However, treatment by shallow evaporation ponds in the open air remains, until now, the most used technique despite the efforts made. The volume and characteristics of this liquid effluent depend, among other things, on the nature of the extraction process used. In this context, this work aims to evaluate the effect of the mode of trituration and storage in the evaporation ponds on the quality of olive oil mill wastewaters. These effluents were collected from three olive mills located in two different provinces in Northern Morocco during the 2021–2022 olive growing season. The sampling has considered different points according to different steps of the process. The analytical work corresponded to the measurement of in-situ parameters (Temperature (T°), Dissolved Oxygen (DO), Electrical Conductivity (EC) and pH degree (pH)) and other laboratory analysis (Suspension Matter (SM), Dry Matter (DM), Fatty Matter (FM), biochemical (BOD5) and chemical (COD)demands in oxygen). Results showed a high degree of environmental degradation. Indeed, these effluents are characterized, on average, by elevated concentrations of biological and chemical oxygen demands and suspended solids reaching up to 0.43 g/L ± 0.87, 1.69 g/L ±0.71 and 30.78 g/L ±25.1, respectively. This study also showed, except for two-phase olive mill BNANDA, a slightly alkaline nature of the vegetable waters (7.81<pH<8.52), as opposed to what was reported in the literature, and high levels in fat content (4.73 g/L ±3.85). Moreover, the estimated volume of vegetable water released in the study area during the 2019/2020 olive growing season (350×103 m3) is very high considering its equivalence to domestic water. Normalized Principal Component Analysis (ACPN) and Hierarchical Principal Component Classification (HCPC) indicate that differences in the composition of this wastewater were more pronounced between the extraction processes than by the origins of the vegetable waters (fresh or stored in the natural evaporation pond).

Opis:
In recent years, the world has been witnessing serious ecological imbalances due to the catastrophic situation and the damage caused to the environment. Human activities as waste disposal, cement units, smelting, chemical industries etc., are the main causes of pollution. Air pollution directly affects the human living standards, pollutants requires regular control in view of their direct impact on health, such as nitrogen oxide, sulfur dioxide, ozone, and particulate matter. Algeria adopts international standards to monitor the levels of pollution recorded in Algerian cities and compare them with global levels. In this context, quantitative estimates of polluted waste resulting from some industrial activities have been conducted in order to determine the degree of its danger and the extent of its contribution to the deterioration of the air quality. The monitoring of pollutants allowed us to identify the benefits of comprehensive environmental assessment. We determined the air quality index in Annaba using various pollutants parameters (dust, ozone, nitrogen dioxide and sulfur dioxide). A ten-point scale ranking of the overall air quality index of pollution accepted in Algeria allows making the differentiated assessment of negative impacts of existing industrial agglomerations on the environment. However, the analysis performed on samples DC1 and DC2 with SEM (TESCAN model VEGA II) and BSE detector (Backscattered Electrons) shows that the particles sizes are estimated to range from hundreds of microns to a few microns, a different morphology and irregular shape. Our results will enable policy makers to appropriate measures to be taken, and which are based mainly on sensitizing economic operators to environmental issues in order to adopt an environmentally friendly industrial system.
W ostatnich latach świat był świadkiem poważnych zaburzeń równowagi ekologicznej z powodu katastrofalnej sytuacji i szkód wyrządzonych środowisku. Działalność człowieka, taka jak usuwanie odpadów, cementownie, hutnictwo, przemysł chemiczny itp. są głównymi przyczynami zanieczyszczenia. Zanieczyszczenie powietrza bezpośrednio wpływa na standardy życia ludzi, zanieczyszczenia wymagają regularnej kontroli ze względu na ich bezpośredni wpływ na zdrowie, takie jak tlenek azotu, dwutlenek siarki, ozon i pył zawieszony. Algieria przyjmuje międzynarodowe standardy w celu monitorowania poziomów zanieczyszczeń rejestrowanych w algierskich miastach i porównywania ich z poziomami globalnymi. W tym kontekście przeprowadzono ilościowe szacunki zanieczyszczonych odpadów powstających w wyniku niektórych działań przemysłowych w celu określenia stopnia ich zagrożenia i zakresu ich wkładu w pogorszenie jakości powietrza. Monitorowanie zanieczyszczeń pozwoliło nam zidentyfikować korzyści płynące z kompleksowej oceny środowiska. Określiliśmy indeks jakości powietrza w Annabie, wykorzystując różne parametry zanieczyszczeń (pył, ozon, dwutlenek azotu i dwutlenek siarki). Dziesięciopunktowa skala rankingu ogólnego wskaźnika jakości powietrza zanieczyszczeń przyjętych w Algierii pozwala na zróżnicowaną ocenę negatywnego wpływu istniejących aglomeracji przemysłowych na środowisko. Jednak analiza przeprowadzona na próbkach DC1 i DC2 za pomocą SEM (TESCAN model VEGA II) i detektora BSE (Backscattered Electrons) pokazuje, że rozmiary cząstek szacuje się na od setek mikronów do kilku mikronów, o różnej morfologii i nieregularnym kształcie. Nasze wyniki umożliwią decydentom podjęcie odpowiednich środków, które opierają się głównie na uwrażliwieniu podmiotów gospodarczych na kwestie środowiskowe w celu przyjęcia przyjaznego dla środowiska systemu przemysłowego.

Opis:
This study focuses on mapping the groundwater’s vulnerability to pollution in the region of Ouargla, located in the North-East of the northern Sahara, exposed to potential risks of alteration. By applying the methods (GOD, DRASTIC, and SINTACS), coupled with a Geographic Information System (GIS), we were able to identify a medium to high vulnerability trend. In light of the results recorded, the DRASTIC and SINTACS methods prove to be more suitable for our study region. This makes it possible to highlight the recharge zones and land use as being the most vulnerable in the territory studied. The GOD method presents a strong vulnerability trend over 77.02% of the study area. Such a result is directly related to the depth of the water table. It can therefore be argued that this method is far from being representative of the reality on the ground because of these very heterogeneous characteristics.

The purpose of this study is to evaluate the level of heavy metal contamination in the spoil heaps of the former Ain Aouda mine (Taza). In this regard, solid samples of the study area were sampled. The set of analyses carried out have detected the presence of zinc (Zn), lead (Pb), copper (Cu), arsenic (As) and nickel (Ni) that remain in these metal discharges. The calculation of contamination/pollution indices: the Geo Accumulation Index (Igeo), the Enrichment Factor (EF) and the Pollution Index (IP) were used to predict the extent of heavy metal contamination. The results of this study suggest that the spoil heaps reveal polymetallic contaminations allowing the trace metal elements to be classified in the following order Zn ˃ Pb ˃ As ˃ Cu > Ni. Knowing well that the alteration and erosion of this stock of mine waste could contribute to the degradation of the natural environment by these elements that are present.

This study investigates the current trace elements concentrations of snow and de-icing using ICP-MS, and phytotoxicity using three vascular plants in snow. The study assesses the contamination, classification and phytotoxicity of snow quality removed from roads of residential areas and piled on children’s playgrounds in residential territories. The research found that according to Russian environmental quality standard for water has been identified the exceeding trace elements in snow by W, Se, Mn, Cu, V, Mo, Ni and Zn. The pollution indices (PLI, CF and Zc) were identified pollution level of snow piles from moderate contamination to very high contamination. Based on average germination index values for Sinapis alba L., Lepidium sativum L., and Triticum aestivum L., the degree of inhibition in snow piles varied from no inhibition to strong inhibition. The trace elements content in de-icing “Galit А” and salt sand mix are defined in the following descending order: Zn > Mn > Ba > V > Rb > Sr and Mn > Ba > Cr > V > Sr > Ni, respectively. High concentrations of trace elements in snow piles are a source of environmental pollution. To prevent snow storage and disposal in residential areas should be involved in future studies of environmental pollution and circular economy, so that environmental managers can reduce threats to the environment and public health, as well as initiate circular economy projects in urban areas.

Opis:
Liquid chromatography-mass spectrometry was used to detect and analyze phenolic compounds in the surface waters of four urban lakes in Xi’an – Hancheng Lake, Xingqing Lake, Nanhu Lake, and Taohuatan Lake. A total of 5 phenolic compounds were detected from the water samples, with a concentration range of ND-100.32 ng/L, of which bisphenol A (BPA) and nonyl phenol (NP) were the main types of phenolic compounds pollution in the four lakes. Pearson correlation analysis was used to analyze the concentration of phenolic compounds in the lake waters of Xi’an City and the water quality indicators COD, TP, NH3 -N, DO, and pH during the same period. It was found that there was a significant positive relationship between the concentration of BPA and COD, the concentration of estradiol (17-beta-E2), estrone (E1) and TP and TN, the concentration of octylphenol (4-t-OP) and pH. The ecological risk assessment (ERA) shows that the concentration of BPA, 4-t-OP and NP in the lakes is at a medium risk level( is between 0.1–1), and that of E1 is at a high risk level (is greater than 1). Female cells (breast cancer cells) and male germ cells (testis cells) of mice were used as research objects to explore BPA and NP Toxic effect on mouse germ cells. BPA and NP at a concentration of 10-8 mol/L were found to have the most value-inducing effect on MCF-7 breast cancer cells positive for estrogen receptor. Obviously, both BPA and NP can induce the proliferation of testicular Sertoli cells.

Opis:
The major goal of this research was to employ honey as a bio-indicator to identify the heavy metal levels in bee honey in the Istog, Drenas, and Kastriot regions. As a result, honey was purposely tested in these locations, and two industrial specific areas were chosen for examination and analysis: Kastriot (Graboc) and Drenas (Vrboc), as these are considered to be among the most industrial polluted areas. A honey sample was also taken in the Istog (Vrell, as a clean area) region in order to compare not just honey, but also the area where the bee obtains nectar, as well as the sources of pollution discharge into the environment. Concentrations of heavy metals in honey, (min. and max.) amounted to: Zn (8.705–9.804 mg/kg), Mn (5.620–5.718 mg/kg), Fe (3.635–3.745 mg/kg) and Cu (2.295–2.299 mg/kg). In contrast, lower concentrations of metals, have been observed for: Ni (0.640–1.126 mg/kg), Pb (0.235–0.268 mg/kg), As (0.107–0.199 mg/kg), Cd (0.040–0.058 mg/kg) and Cr (0.025–0.036 mg/kg) while elements such as; Hg, and Co, are almost undetected. The study of hierarchical clusters revealed several groupings of elements with geogenic and anthropogenic origins. The concentrations of heavy metals selected for honey were compared to standards of other countries, such as Poland and other European Union countries. Samples were taken in October 2020 and September 2021. The concentration of heavy metals was determined using inductively coupled plasma optical emission spectrometry, ICP OES.

Opis:
Reduction of ecological risks of shipping is a challenging task that requires methods of legislative and regulatory control, organizational measures, and technical and technological support. Furthermore, the matter concerns not only the reduction of possible risks but also the level of existing impact on the marine environment because of exhaust gas emissions by ships, discharge of waste and ballast water, as well as control of ecological consequences of accidents. The purpose of this study is to analyse possible sources of environmental impact during ship operation cycles, identify significant risks, review existing potentials to reduce the risk of ship accidents and their environmental consequences, and develop solutions to existing problems. This study offers results, which can serve as the initial basis for the formation of comprehensive measures on the reduction of environmental risks, and consequences of possible accidents for the environment caused by ships and international shipping.

Opis:
The article presents the results of monitoring the aftereffect of the use of excessive zonal doses of mineral fertilisers on soil contamination with heavy metals (HM). With traditional soybean cultivation technology, the level of soil contamination when applying excessive doses (N60 P180 K90) of fertilisers is quite high and indicates violations of the ecological balance of the agroecosystem. By the nature of the accumulation of heavy metals in meadow-chestnut soil, depending on the application of the studied doses (P60 K30, N30 P60 K30, N60 P180K90) of fertiliser, the content of HM (Pb, Zn, Cd) increases. The greatest contamination of the soil with Cu was revealed, the content of which increases to 3.2 mg∙kg-1 of soil, which is higher than the threshold of the maximum permissible concentration (MPC) - 3.0 mg∙kg-1. According to the level of contamination of the soil with copper, it belongs to the highly dangerous classes. In a comparative assessment of the level of soil contamination with HM, optimal norms of mineral fertilisers have been established, namely, against the background of effective resource-saving technology for growing soybeans. The application of fertilisers at a dose of P60 K30 and N30 P60 K30 does not significantly affect the level of soil contamination with HM, optimises the ecological state and nutrient regime of the soil, preserves and restores soil fertility indicators, and increases soybean productivity. This resource-saving technology provides a safe environment for soybean cultivation and a significant increase of 34.5-38.6% in crop productivity (0.53-0.76 Mg∙ha-1) and yield (2.57 Mg∙ha-1).

Opis:
The article reveals the aspects of environmental and economic assessment of the land use regulation effectiveness. It is emphasized that in order to useland resources rationally and successfully implement scientifically sound farming methods, it is necessary to have holistic and reliable information about land, its productive properties, natural and economic condition. It is noted that the efficiency of land use should have quantitative parameters characterizing each of the aspects directly involved in the process of land use regulation.
W artykule przedstawiono aspekty środowiskowej i ekonomicznej oceny skuteczności regulacji dotyczących użytkowania gruntów. Podkreśla się, że aby racjonalnie wykorzystywać zasoby ziemi i skutecznie wdrażać naukowo uzasadnione metody gospodarowania, konieczne jest posiadanie całościowej i rzetelnej informacji o ziemi, jej właściwościach produkcyjnych, warunkach przyrodniczych i ekonomicznych. Należy zauważyć, że efektywność użytkowania gruntów powinna mieć parametry ilościowe charakteryzujące każdy z aspektów bezpośrednio zaangażowanych w proces regulacji użytkowania gruntów.
