The goal of this work is to recycle waste goat bones in an environmentally acceptable way and then recover them for vital applications as an adsorbent of hazardous pollutants from water, an antimicrobial agent, and a catalyst. Recycled goat bone crystals (RGB) were characterized via thermal gravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscope (SEM), transmittance electron microscope (TEM), and Fourier transform infrared spectroscopy (FTIR). TGA data revealed that the goat bones sample consists of approximately 29.30 % organic residue and 70.70 % hydroxyapatite. The crystalline size was 3.65 nm and the particle size was 5–10 nm as resulted from XRD analysis and TEM images, respectively. The FT-IR spectrum showed the presence of functional groups of hydroxyapatite and organic molecules. RGB is used as a heterogenous catalyst in multicomponent reactions for synthesizing several tetrahydrobenzo [b]pyrans by employing a one-pot, three-component reaction comprising aromatic aldehydes, cyclohexane-1,3‑dione, and malononitrile in water at room temperature with an excellent yield ≈ 90–98 %. Compared to earlier studies on the synthesis of 4H-pyrans, our technique offers a number of benefits, such as increased yields, eco-friendly conditions quicker reactions, and recyclable. The antimicrobial capacity of RGB has been evaluated and compared with that of organic residue and hydroxyapatite extracted from RGB using colony counting technique. The petri dish containing hydroxyapatite showed minimal growth of microbes with inhibitions of 82.1 % and 98.7 % for both bacteria and fungi growth, respectively. Additionally, RGB has been studied as an adsorbent for wastewater purification and showed high removal efficiency of crystal violet dye ≈ 99.15 % after 30 min under the optimum conditions. As a result of this work, the RGB can be used on a large scale as a cheap and a promising commercial catalyst, biosorbent, and antimicrobial agent.

Higher activity liquid wastes pose a significant management challenge at nuclear sites, and there is a strong drive to develop cost-effective (and more sustainable) waste treatment solutions that can remove radioactive and other contaminants from these liquid radioactive wastes (LRW) prior to their discharge or final storage/disposal. Here, results are presented from an on-site trial of a coupled non-thermal plasma / sorption-based LRW treatment system at the “Dibrova” Object in the Chornobyl Exclusion Zone. Over 2m³ of Cs-137 and Sr-90 contaminated LRW from settling tanks used for the holding of tailings and drain water from Chornobyl Building № 5 and deactivation solutions (used in the liquidation efforts following the 1986 Chornobyl disaster) were treated. The coupled treatment process removed greater than 90 % of Cs-137 and Sr-90 from the most contaminated liquids (containing 75 Bq/kg (Cs-137) and 195 Bq/kg (Sr-90)), generating a low mass (<100g ) iron-rich solid residue suitable for onward storage/disposal. Treatment efficiencies for other waste components (e.g. nitrites, phosphates and COD) were equivalent to or exceeded those previously reported for treatment of environmental liquid wastes by similar Advanced Oxidation Processes. The power requirements of the system (due to the pulsed nature of the plasma generated) were relatively low, at 10 kWh, for a LRW treatment rate of 15 - 20 L/h. The system can be operated remotely in autonomous mode, and its modular, easily transportable nature means that the process can be readily adapted for various on-site treatment scenarios.

Surveillance of antimicrobial resistance (AMR) is necessary and urgent. This study emphasizes the critical role of One Health surveillance in monitoring AMR, integrating metagenomics to assess microbiota and antibiotic resistance genes (ARGs) across human, pig, and soil ecosystems in swine farms. The human and pig gut microbiota are predominantly composed of the phyla Firmicutes, Bacteroidota, Proteobacteria, and Actinobacteria, whereas the soil microbiota exhibits a distinct profile, with Proteobacteria, Acidobacteria, Actinobacteria, and Planctomycetes being the most prevalent. A diverse array of ARGs is identified, including multidrug resistance, with Acidobacteria and Proteobacteria as potential ARG hosts. The study reveals shared ARGs and mobile genetic elements (MGEs) among human, pig, and soil, indicating microbial interdependence and potential for horizontal gene transfer. A positive correlation between biocide and metal resistance genes (BMRGs) and MGEs suggests the role of disinfectants and metals in ARG selection and dissemination. Network analysis of BMRGs, MGEs, and ARGs finds positive associations between copper resistance genes (corR), zinc and lead resistance genes (zraR/hydH, zraS/hydG), and ARGs such as macB, tetA(58), mlaF, and mtrA. This correlation is also evident with insertion sequences like ISAcba1 and ISArsp9. The findings reveal the potential for horizontal gene transfer and the influence of disinfectants and metals on ARG selection and dissemination, advancing the application of metagenomic monitoring within the One Health framework. This research underscores the need for integrated strategies to mitigate antibiotic resistance and informs sustainable agricultural practices.

Indoor environment is considered to be a sanctuary from external pollutants. But nowadays, this idea has been changed. Heavy metals (HMs) contamination in indoor dust poses a significant threat to ecological and human health. This study had been conducted in four types of indoor environments: residential, institutional, industrial, and commercial. Dust sample was collected from the AC filter. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used to analyze those samples and identified 11 types of HMs (As, Cd, Co, Cu, Cr, Fe, Hg, Mn, Ni, Pb, Se, and Zn) in AC dust. Among the HMs, Fe (717.41 ± 19.04 mg/kg) was the most abundant, and Cd (2.53 ± 0.35 mg/kg) was the least abundant. Principal component analysis was carried out to understand the pattern of metals by area. It was found that As, Se, and Cr was the most abundant group among the study area. Carcenogenic and Non carcinogenic risk was also assessed for this HMs. While ingestion was the main exposure route for non-carcinogenic risk and inhalation was for carcinogenic risk. As, Cr, Cd, and Cu pose carcinogenic threats higher than safe values except Pb. Both non-carcinogenic risk and carcinogenic risk for Cr were in the unacceptable range for adults. Additionally, some indices that this study evaluated indicate a variation in risk due to the presence of HMs. This study first time identified the Hg in every sample of dust and introduced us about that hidden threat. These results also shed the light on the critical interplay between indoor contaminants and public health, urging stronger laws and increased public awareness to protect vulnerable groups.

Catalysts are a crucial component of fuel cells, and graphene-based catalysts have been extensively studied as cost-effective alternatives to Pt catalysts. This study aims to investigate the issues of functionalized and doped graphene as a catalyst for proton-exchange membrane fuel cells (PEMFCs) and analyze the trends through bibliometric analysis. Data were retrieved from the Scopus database, including 1175 scientific articles published between 2008 and 2023 and excluding review papers. VOSviewer and Publish or Perish software were used to analyze the data and obtain information regarding publication and citation metrics, author countries, most cited papers, subject areas, co-authorship, and keyword co-occurrence for mapping research trends. The results revealed fluctuations in the annual publication and citation metrics of articles on functionalized and doped graphene-based catalysts during the research period. Wang et al. published the highest number of articles. The authors demonstrated global cooperation on many interrelated research topics. The 2011 study by Liang et al. on catalyzing CO₃O₄ nanocrystals in graphene was the most cited. Finally, keyword co-occurrence analysis identified research trends in PEMFA development, such as 1) developing carbon sources for PEMFC catalysts and 2) optimizing Pt group metal-free PEMFC catalysts. Thus, this study provides an overview of research hotspots on functionalized and doped graphene-based catalysts for PEMFCs and highlights their potential to drive innovation. Future work should address the stability and cost-effectiveness of functionalized and doped graphene compared to commercial Pt/C catalysts in improving PEMFV performance.

To improve trace element (TE) phytoextraction techniques, the use of soil amendments and the co-cropping of accumulator species have been often studied. This study aimed to evaluate the possibility of combining the application of elemental sulfur (S₈) with the co-cropping of two TE accumulating species, Alliaria petiolata and Salix aquatica grandis. A pot experiment was conducted with two soils, lightly (LC) and heavily contaminated (HC) by TE, originated from an industrial wasteland. The application of S₈ significantly reduced pH by 1.17 and 1.23 unit after 64 days in LC and HC soils, respectively, and increased Cd, Cr, Mn, Ni, Pb and Zn contents in soil extractable fraction and plants. An increase in the TE-extraction potential was observed and was greater in LC soil, as the S₈ application led to a reduction of biomass produced by both plants in HC soil. However, co-cropping treatment on HC soil maximized the extraction of TE, especially for Cr and Ni when S₈ treatment was applied, since the plants showed no competition but rather differences in the elements accumulated. Consequently, the combination of S₈ and the co-cropping of A. petiolata and S. aquatica grandis was shown to be relevant for the phytoextraction of TE in HC soils.

Uranium (U) contamination in soil, derived from industrial activities and nuclear facility operations, poses significant environmental and health risks. This study explores an innovative remediation approach combining physical separation and chemical washing to treat U-contaminated fine soil. Fine soil samples (< 0.2 mm) were subjected to a series of experiments focusing on the selective separation of silt and clay particles using PEI-coated γ-Fe₂O₃ magnetic nanoparticles followed by a two-step acid washing treatment. The magnetic separation effectively targeted negatively charged clay particles, utilizing strong electrostatic attraction to form flocs, which were then easily separated under a magnetic field. Two-step chemical washings were performed at room temperature to decontaminate the fine soil, employing H₂SO₄, HNO₃, Na₂CO₃, and NaHCO₃. The highest U removal efficiency was achieved using 1.0 M H₂SO₄, reducing the residual radioactivity to below the clearance level recommended by IAEA (< 1.0 Bq/g). This combined method proved highly effective, showing over 99% U removal efficiency for fine soils larger than 0.5 mm without significant soil loss. The research highlights the potential for integrating advanced material sciences into environmental remediation practices to mitigate the risks associated with U-contaminated soils.

Chlorinated hydrocarbons (CHCs), toxic and persistent pollutants from pesticides/solvents, threaten groundwater and human health. At this stage, research on soil adsorption of CHCs has many limitations in terms of soil media, pollutant types and the influence of soil properties, which restricts the in-depth development of pollution prevention and control and risk assessment. This study investigated the adsorption behavior of three CHCs in different soil types through batch static adsorption experiments, combined with adsorption kinetics and isotherm models. Grey correlation analysis was used to determine the relative importance of various influencing factors. Results indicated that clay soil exhibited the highest adsorption capacity for CHCs, with the highest adsorption level of 1,2,4-trichlorobenzene. Specifically, clay soil showed the highest adsorption of 58.86 μg/g of the three CHCs, which was greater than loam soil (52.4 μg/g) and sand soil (46.5 μg/g). The maximum adsorbing capacity of 1,2,4-trichlorobenzene was reaching 58.86 μg/g, which was greater than that of chlorobenzene (50.1 μg/g) and carbon tetrachloride (40.5 μg/g) in the same soil medium. Furthermore, the study revealed that soil pH influenced the adsorption capacity of CHCs, with neutral pH resulting in the weakest adsorption. The analysis also identified the order of importance of influencing factors for different CHCs. For 1,2,4-trichlorobenzene and chlorobenzene, pollutant concentration was the most influential factor, followed by particle size, zeta potential, pH, and organic matter content. On the other hand, for carbon tetrachloride, pollutant concentration was the most significant factor, followed by particle size, organic matter content, zeta potential, and pH. This study effectively remedied the limitations of the research on soil adsorption of CHCs at the present stage, and provided an important scientific basis for environmental risk assessment and soil pollution prevention and control.

This research focused on the development of 9 advanced Dopamine/β-Cyclodextrin modified polyethersulfone (PES) membranes, incorporating a polymer-coated magnetic activated biochar-zeolite composite (PMACZ) and NH₂-MIL-101(Al) metal organic framework (MOF) in varying proportions. Membranes were designed for extraction of microplastics (MPs) and Decachlorobiphenyl (PCB 209) from synthetic landfill leachate (SLL). Characterization of the synthesized membranes was conducted using scanning electron microscopy and energy dispersive spectroscopy (SEM/EDS), Brunauer–Emmett–Teller (BET) analysis, X-ray diffraction (XRD), and raman spectroscopy. The membranes were evaluated for permeate flux, rejection efficiency, and fouling behavior. The membrane exhibiting optimal performance was selected for further examination, including cyclic stability, rejection and release performance, and pH tolerance. The rejection tests revealed complete removal of MPs and PCB 209 in water, while in SLL, removal rates were 100% for MPs and 99.67% for PCB 209. A decline in removal efficiency was observed with increased cycles. However, this decline was not significant. Release performance tests indicated negligible release (0% for MPs and 0.32% for PCB 209 in RO water; 0% for MPs and 0.8% for PCB 209 in SLL). Release of MPs under reversed flow conditions simulating backwash demonstrated rates of 95% and 93%. Notably, removal efficiencies exceeded 96% across all tested pH ranges, with optimal performance observed at pH levels of 5–8 for MPs and pH 8 for PCB 209, achieving complete removal. The membranes exhibited high permeability, 20 % enhanced fouling resistance, and exceptional rejection of both contaminants, affirming their potential for application in landfill leachate filtration.

这项研究的重点是开发 9 种先进的多巴胺/β-环糊精改性聚醚砜（PES）膜，其中包含不同比例的聚合物包覆磁性活化生物炭-沸石复合材料（PMACZ）和 NH2-MIL-101(Al)金属有机框架（MOF）。设计的膜用于从合成垃圾填埋场渗滤液（SLL）中提取微塑料（MPs）和十氯联苯（PCB 209）。使用扫描电子显微镜和能量色散光谱仪（SEM/EDS）、Brunauer-Emmett-Teller（BET）分析、X 射线衍射（XRD）和拉曼光谱仪对合成膜进行了表征。对膜的渗透通量、排斥效率和堵塞行为进行了评估。选择了表现出最佳性能的膜进行进一步检查，包括循环稳定性、排斥和释放性能以及 pH 值耐受性。排斥测试表明，在水中可完全去除 MPs 和 PCB 209，而在 SLL 中，MPs 的去除率为 100%，PCB 209 的去除率为 99.67%。随着循环次数的增加，去除效率有所下降。但下降幅度不大。释放性能测试表明，释放量微乎其微（在反渗透水中，多氯联苯的释放量为 0%，多氯联苯 209 的释放量为 0.32%；在 SLL 中，多氯联苯的释放量为 0%，多氯联苯 209 的释放量为 0.8%）。在模拟反冲洗的反向流动条件下，多氯联苯的释放率分别为 95% 和 93%。值得注意的是，在所有测试的 pH 值范围内，去除率都超过了 96%，其中 MPs 在 pH 值为 5-8 时和 PCB 209 在 pH 值为 8 时性能最佳，实现了完全去除。这种膜具有高渗透性，抗污垢能力提高了 20%，对这两种污染物的去除率都非常高，这充分证明了它们在垃圾填埋场渗滤液过滤中的应用潜力。

Coal mining is one of the most significant mining operations in India. Post-mining activities, often result in abandoned sites known as coal voids. Water accumulated in coal void reservoirs undergoes substantial changes in physico-chemical and biological characteristics due to heavy metal contamination. Tilapia (Oreochromis niloticus) with an average weight of 254.50 ± 17.65g was randomly collected from established cage cultures in two reservoirs: Ramgarh coal void reservoir (test) and Getalsud reservoir (control) in Jharkhand, India. The objectives of the study were to delineate the effects of heavy metal exposure on hemato-immunological, biochemical, molecular, and histopathological responses in fish. The heavy metal assessment of the tilapia tissues revealed that the test group had significantly higher levels of Cr, Ni, As, Se, Pb, Zn, and Fe than the control group collected from Getalsud reservoir. Similarly, higher level of Cr, As, Pb and Fe was observed in the water sample of the test group. A significant increase in serum indices, enzymes related to oxidative stress and metabolic enzymes was observed in fish from the metal-contaminated coal void reservoir. An increasing trend in pro-inflammatory cytokine genes (TNF-α, IL-1β, and HSP-70) and downregulation of the anti-inflammatory cytokine gene (TGF-β) were observed in fish collected from coal void reservoirs. Histopathological examination of the liver and gill tissues demonstrated several deleterious alterations in coal void raised fish. The study concluded that metal contamination in coal voids profoundly affects key biomarkers of cellular, metabolic, and molecular responses in fish, indicating serious ecological and aquacultural implications.
