    By diminishing the activities of superoxide dismutase (SOD), glutathione (GSH), and catalase (CAT) and concurrently increasing malondialdehyde (MDA) levels, TMX exposure significantly induced oxidative stress in the affected groups. Following hematoxylin and eosin staining, a microscopic assessment in TMX-exposed animals revealed vacuolated, deteriorated luteal cells in the corpus luteum. Within a follicle, a degenerated oocyte was found, and the circular muscle layer displayed degeneration/necrosis with a high apoptotic rate. TMX resulted in transcriptional modifications of apoptosis-related genes, subsequently triggering activation of the intrinsic apoptotic pathway. The findings from the study unequivocally demonstrate the detrimental effect of TMX on the reproductive well-being of female Wistar rats.

    Our lives are dramatically transformed by the considerable advancement in nanotechnology. Despite its benefits, the process continues to inflict environmental harm. This research endeavors to leverage Helix aspersa, the land snail, as a bioindicator. Over two weeks, titanium dioxide nanoparticles (TiO2NPs) at 70 and 140 g/L were applied using the spraying method. Studies were conducted to ascertain oxidative biomarkers, condition index (CI), DNA damage, hemocyte count, and phagocytic activity. The toxicity of TiO2 nanoparticles (TiO2NPs) was ascertained, with an LC50 of 544 g/L. duvelisib inhibitor Exposure to TiO2NPs significantly diminished the activity of both superoxide dismutase (SOD) and catalase (CAT) in the digestive gland of Helix aspersa. The catalase (CAT) activity measured at 3401 (P=0.0001), and SOD at 111 (P=0.00002), at a 140 g/L concentration after the two-week exposure. The activity of glutathione peroxidase (GPX) at 140 grams per liter was 113001 units per milligram of protein, substantially lower compared to the controls, which displayed an activity of 547001 units per milligram of protein. The treatment administered led to DNA damage in hemocytes, quantified by a tail DNA percentage of 866002 and a tail moment of 52990 at a concentration of 140 g/L (P=0002). The digestive gland displayed an elevation in both tail DNA percentage and tail moment, with the tail moment reaching 7838008 compared to the control’s 229009 (P = 0.00001). There was a pronounced decline in the total hemocyte count after fourteen days, decreasing from 7911 in control samples to 7115 at a concentration of 140 g/L. The digestive gland of Helix aspersa exhibited histological changes following exposure to TiO2NPs. The results definitively suggest that the Helix aspersa can be utilized as a bioindicator for environmental contamination. Thorough investigation of the toxic effects induced by TiO2 nanoparticles in in vivo studies is crucial.

    The serious environmental problem of acid mine drainage (AMD) frequently occurs in mining areas. For the successful management of AMD pollution, understanding the key processes and pathways involved in hydrogeochemical evolution is vital. By employing hydrogeochemical analysis and environmental isotope tracing techniques, the hydrogeochemical processes leading to groundwater pollution in the multi-aquifer system of the abandoned Dashu pyrite mine in Southwest China were determined. Employing the deuterium excess parameter ‘d’ from groundwater samples, and incorporating findings from 2H, 18O, and T analyses, the intensity of water-rock interaction was ascertained. Groundwater d-T distribution characteristics indicated a primary origin from the Quaternary reservoir platform aquifers and close hydraulic interconnections among the various aquifers. The investigation of sulfur isotopes and ion content in water samples indicated that groundwater sulfur was largely derived from the dissolution of gypsum, in contrast to mine water sulfur, which stemmed primarily from pyrite oxidation. In consequence of mining operations, as indicated by hydrogeochemical inversion results, water table fluctuations, water-rock interaction intensification, alterations in hydrogeochemical processes, and aquifer-mine water contamination resulted. The study’s findings illuminate the theoretical aspects of identifying pollution sources and pivotal hydrogeochemical processes that affect groundwater in mining areas with multiple aquifers, contributing to the development of technical support for water source control and prevention strategies.

    The comprehensive utilization of iron ore tailings (IOTs) resulted in not only the resolution of environmental problems, but also significant economic gains. Employing a novel synthetic approach, this study demonstrates the creation of ZSM-5 microspheres from IOTs. A study of zeolite formation, employing various analytical procedures, examined the influence of the Si/Al molar ratio and the pH of the precursor solution. Using the methanol-to-propylene (MTP) reaction, the catalytic activity of the catalyst prepared via solid-phase conversion (MP-ZSM-5) was assessed. The MP-ZSM-5 catalyst, prepared through an alternative method, outperforms the HM-ZSM-5 catalyst (prepared via the hydrothermal method) by not only increasing the catalytic lifetime from 187 hours to 360 hours but also displaying a higher propylene selectivity (437%) in comparison with the latter (386%). The Kissinger-Akahira-Sunose (KAS) model is utilized to investigate the kinetics of template removal in the TG outcome. Removal of CTAB entails an average activation energy of 201,111,342 kJ/mol, whereas TPABr removal requires an average activation energy of 326,881,691 kJ/mol. In addition, this outcome is strongly associated with model-free kinetic algorithms, allowing the determination of conversion and isoconversion rates for TPABr and CTAB degradation within ZSM-5, providing important direction for industrial production strategies.

    The methodological approach detailed in this article involves the use of manganese (Mn3+Mn7+)-modified black titanium dioxide (Mn/BTiO2) as a photocatalyst to achieve optimized visible-light-driven photodegradation of treated agro-industrial effluent, TPOME. Employing a modified wet chemical technique, BTiO2 was prepared. The BTiO2 material was subjected to a wet impregnation process with manganese, followed by calcination at 300 degrees Celsius for one hour, ultimately producing Mn/BTiO2. Mn/BTiO2’s photo-assisted role in mitigating chemical oxygen demand (COD), phenolic compounds (PCs), color, and total organic carbon (TOC) was investigated. Employing a design of experiments (DOE) methodology, the photocatalytic process conditions, encompassing photocatalyst loading, manganese concentration, hydrogen peroxide (H2O2) dosage, and irradiation time, were systematically optimized. At the optimal conditions—a photocatalyst load of 0.085 g/L, a hydrogen peroxide dose of 0.0048 mol/L, a manganese concentration of 0.301 wt.%, and an irradiation time of 204 minutes—the removal efficiencies for COD, PCs, color, and TOC were 88.87%, 86.04%, 6.28%, and 84.66%, respectively. Statistical analysis underscored the significant impact of removing the response variable from TPOME estimation, exhibiting a high R-squared and exceptionally low Root Mean Squared Error, Mean Squared Error, Mean Absolute Deviation, Mean Absolute Error, and Mean Absolute Percentage Error, highlighting substantial reliability. This investigation highlighted the substantial potential of the developed photocatalytic system in remediating waste effluent stemming from palm oil and other agricultural sectors, showcasing its ability to simultaneously decrease numerous organic pollution indicators.

    In comparison to the dispensable use of LPG, a solar cooker is crucial for preparing food brimming with essential nutrients. The present situation has allowed the solar cooker, featuring a nanoparticle coating, to exhibit improved thermal performance and quicker cooking. The attempt to forecast thermal performance using the Fourier series was undertaken, and the study of cooking liquid temperatures was corroborated utilizing the Fourier series. Moreover, the cooking process, encompassing climate, has been logically modeled and fuzzified for the creation of fuzzy rules. The experimental procedure incorporated a thermal measurement of the cooking process to support the efficacy of the fuzzy inference. The study suggests that fuzzy logic modeling and Fourier series analysis can both be employed to simulate the proposed system, mirroring Chennai’s local climate conditions across a range of comparable settings. To assess the total percentage reduction in carbon dioxide emissions during the deployment of a solar box cooker, a study of environmental and economic factors is implemented, contrasting it with the comparatively more dependent Pt values. Minimizing CO2 emissions is directly correlated with Pt values. 526% efficiency was determined for boiling water; a marked difference of 3899% efficiency was measured in the oil when it reached its steady-state temperature.

    Environmental concerns and the challenge of securing resources are driving industrial manufacturing companies to develop symbiotic partnerships. The elucidation of symbiotic partnerships promotes more sustainable industrial growth. However, the sectors represented by businesses located in industrial parks are varied and diverse. To create a lasting symbiosis network in industrial parks, a comprehensive evaluation of the interdependent relationships of each sector is imperative. Accordingly, the process of installing the symbiosis network will be less complex and more sustainable in its approach. The objective of this study, in the context provided, is to pinpoint the sector most suitable for a symbiotic network’s formation through the deployment of a groundbreaking approach for the assessment of symbiotic possibilities. This required the specification of criteria that impacted the symbiosis network’s development and its implementation process. Employing a method of multi-criteria decision-making, the problem was successfully resolved. Recognizing the ambiguities embedded in the process, fuzzy multi-criteria decision-making techniques were implemented. Therefore, a model for prioritizing sectors has been put forward, with the aim of creating a symbiotic network structure within industrial parks. The multi-criteria decision-making process established the number of enterprises evaluating waste, in other words, the quantity of customers producing waste, as the top priority criterion.
