This paper introduces a novel non-invasive approach for detecting leukemia cancer using a complementary split-ring resonator (CSRR) biosensor at the 2.45 GHz Industrial, Scientific and Medical (ISM) band. A CSRR biosensor is designed and optimized using the Ansys HFSS simulation software, which utilizes a copper split-ring resonator on a dielectric FR-4 epoxy substrate. The sensor geometry was fine-tuned iteratively to achieve a maximum sensitivity of 46.96 %, which is crucial for biomedical applications. Standard photolithography techniques were adopted to create the sensor, whose performance is validated by making scattering parameter measurements with the help of a vector network analyzer (VNA) yielding excellent agreement with the results of simulations. This biomarker-sensitive CSRR-based sensor uses a fingertip placed non-invasively on an active sensor area. The non-invasive Real-time testing was done on healthy individuals aged 18 to 46 across various blood groups (A1+, B+, O+), with comparative tests involving simulated data for HL-60 leukemia cancer cells. The results showed a downward frequency shift in the presence of cancer cells compared to healthy samples. Sensitivity and permittivity analysis, with permittivity specifically analyzed using MATLAB, confirmed the sensor's ability to differentiate between healthy and cancerous conditions effectively. Furthermore, real-time testing demonstrated consistent S₂₁ parameter behavior, highlighting the sensor's reliability. The main results obtained were a considerable shift downward in the resonant frequency in the case of HL-60 cancer cells in simulation and real-time measurements. This behavior demonstrates the potential of the sensor to identify biomarkers of early-stage cancers by interacting with cells and tissues under the skin. The integration of VNA with the CSRR biosensor allowed for monitoring and analysis with high accuracy, establishing a reliable framework for non-invasive cancer screening.

Microplastics (MPs) are ubiquitous in aquatic habitats and have the potential to seriously harm the ecosystem, creatures, and public health. Microplastic pollution in water has garnered attention, but regional microplastic distribution, shape, and risk are unknown. We collected 42 samples from 14 sampling sites in Kaptai Lake to study the spatial variations, causes, transfer, composition profile, and environmental impact of MPs in water. The sampling was done in January 2024 by using a manta trawl having a mesh size of 300 μm. The MPs in water samples were digested, vacuum filtered and quantified using an optical microscope. The number of MPs ranged from 13.33 ± 6.67 to 683 ± 70.55 items/m³. Plastic particles were most often transparent (38.07 %) and red (11.01 %). MPs types in water were ordered as follows: Fibers > foams > fragments > lines > films > pellets. According to the analysis in Fourier-transform infrared spectroscopy (FTIR), Polyethylene terephthalate (PET) (38.57 %) and polyethylene (PE) (36 %), with filamentous (33.33 %) and irregular (32.37 %) morphologies, were the most common polymers. Most MPs (83.98 %) were between 0.3 and 1.5 mm, followed by 3–5 mm (8.75 %) and 1.5–3 mm (7.27 %). Scanning electron microscopy (SEM) was employed to examine the surface deformation of different polymer types due to environmental exposure where the PE showed the highest degree of deformity. The polymer hazard index (PHI), the potential ecological risk index (RI), and, the ecological risk factor (E_r) values for Lake water indicate serious MPs risk. The pollution load index (PLI) had very low MP contamination. Household wastewater and fishing may be related to local MPs. This study may provide a MPs contamination baseline in Bangladesh's extensive freshwater ecosystem. The results will enhance knowledge of MPs pollution risk and contamination levels, which could facilitate the development of remediation strategies.

The number of landfills for municipal solid waste is growing every year. The aim of our study is to assess the health of soil polluted by municipal solid waste landfill. 13 points were examined: municipal solid waste landfill (No. 1–8), abandoned field (No. 9–11) and cropland (No. 12–13). To assess soil pollution, the following indicators were calculated: the total pollution index (Zc), pollution load index (PLE), potential ecological risk (PERI). Geobotanical description of the sites was investigated, physical, chemical (pH, the content of easily soluble salts, humus content, the gross content of heavy metals), and biological (the total number of bacteria, the activity of catalase, invertase, and dehydrogenases, the length of roots and shoots of radish) indicators were studied. The integral indicator of the biological state of the soil (IIBS) was used to combine different biological indicators. To confirm the reliability and analysis of the obtained results, statistical methods of univariate analysis of the Tukey's post-hoc criterion, correlation analysis using the Spearman's criterion and multivariate factor analysis using the principal components method were used. According to the MPC/APC ratio, soil pollution with Cr exceeded the control by 18 times, Ni — by 4 times, Cu — by 45 times, Zn — by 51 times, As — by 5 times, and Pb — by 6 times. The data of the Z_c and PLE shows a high degree of pollution by heavy metals and an extremely high level of PERI the landfill area. There was a significant decrease in the activity of catalase and invertase and the total number of bacteria by 10–82%. The most informative and sensitive biological indicator was catalase activity. The data obtained by the study shows that the indicators of catalase activity, root length, and the total number of microorganisms can be used in monitoring and diagnosing the health of soils under solid waste landfills and the surrounding area.

Epidemiological studies have suggested that exposure to particulate matter (PM) may increase the risk of developing metabolic syndrome (MetS). However, evidence on the long-term effects of PM exposure on the incidence of individual MetS's components remain limited and inconsistent. This knowledge gap highlights the need for further research to clarify the potential role of PM in the development and progression of MetS over extended periods. Follow-up data collected from a cohort in Eastern China, encompassing 44,720 individuals between 2014 and 2021, were utilized. Residential exposures to fine particles (PM_2.5) and inhalable particles (PM₁₀) for each participant were estimated using a random forest model with a spatial resolution of 1 × 1 km. The generalized estimating equations (GEE) model was employed to assess the associations of long-term PM exposures with incident MetS and its components, as well as with continuous metabolic indicators related to MetS. For each 10 μg/m³ increase in annual average concentration of PM_2.5, there were significant increases in the incidence of MetS (Relative risk: 1.17, 1.10–1.26), elevated triglycerides (TG) (1.17, 1.10–1.24), decreased high–density lipoprotein cholesterol (HDL-C) (1.18, 1.11–1.27), elevated fasting blood glucose (FBG) (2.05, 1.94–2.16), and elevated blood pressure (BP) (1.30, 1.17–1.44). The RR associated with PM₁₀ were smaller compared to PM_2.5 but still statistically significant. The analyses of continuous metabolic indicators indicated that long-term exposure to PM was positively associated with FBG and systolic BP, and inversely associated with HDL-C. This cohort study provides valuable evidence of the increased risk of MetS and its components associated with long-term PM exposure in areas with high pollution levels.

Current research focuses on the potential application of amorphous iron oxyhydroxides, specifically ferrihydrite (FHY) coprecipitated with and without ethylenediaminetetraacetic acid and ethylenediamine-N, N′-disuccinic acid as complexing agents, for the removal of chromium from aqous solutions. The Electron Probe Microanalysis, X-ray diffraction, SEM and TEM Microscopy, N₂ sorption/desorption, and FT-IR Spectroscopy allowed the assessment of the composition, mineralogy, crystallinity, morphology, size, and surface properties of the nanoparticulated samples. The incorporation of chelating agents resulted in differences in nanoparticle morphology, amorphous characteristics, and surface properties, but did not affect the Cr uptake by adsorption. Kinetic results showed fast (1 hour) Cr uptake capacity that increased with pH decrease and rising Cr concentration, approaching saturation at initial Cr concentrations exceeding 100 mg/L. Isothermal studies showed maximum uptake capacities of FHY of 37.79 mg Cr/g _FHY and the best fit to SIPS model indicates that Cr is chemically bound as mono and multiple layers at plain ferrites surface and under light acidic pH. Reuse tests revealed FHY capability of sustaining up to five cycles of adsorption and desorption, and possibly more. This underscores the potential of FHY as a promising adsorbent for the removal of Cr /at contaminated sites. Geochemical modelling was conducted to (i) assess the speciation of Cr (VI) in the solution and (ii) allow comparison of the theoretically simulated adsorption process with the experimentally obtained results. They indicate Cr species available to bind at varying pH and concentrations values, and that no Cr self-precipitation occurred within tested conditions. Interestingly, the adsorption models that were used to best simulate Cr uptake by FHY, did overestimate the experimental results. Hence, there is still a need to improve geochemical modelling software to simulate processes that occur in real settings.

Industries are seriously facing the challenge of air pollution, which can be detrimental to the environment and living beings. Therefore, it is crucial to control this pollution with an eco-friendly approach such as biofiltration. The purpose of the manuscript is to conduct a statistical analysis to analyze the “biofiltration of air” theme and to explore the current state of research development and advancement during 1991–2023. Using relevant keywords, 1475 bibliographic records were identified from the Web of Science database. Based on the findings, research progress was mapped to determine the scientific status, prolific author, and county collaboration, with current scientific and technological developments and knowledge gaps. The USA and China are the world leaders in the use of biofilters for polluted air treatment. The findings of this review identified that the research on biofiltration of air has increased significantly over 33 years. The research trends and potential advancement in biofiltration systems, catalytic oxidation processes, bioaugmentation strategy, and integration technology were addressed. Further, the recent progress of biofiltration modeling using theoretical modeling and ANN was highlighted. Further, the significance of biofilters and their specific progress on biological aspects, biofilter design and operation, pollutant-specific research, and new materials and technologies were emphasized. This is the first study to provide an in-depth discussion and understanding of scientific progress via scientometric review to realize the panorama of global research of polluted air research. The results of this bibliometric review can be constructive inputs to researchers and practitioners of air biofiltration.

Background

Lithium is a crucial commodity; however, the mining and processing of lithium is associated with exposure to Naturally Occurring Radioactive Material (NORM) from the uranium-238 and thorium-232 decay chains. The sources and pathways of exposure include the inhalation of dust containing alpha-emitting radioactive elements, radon, thoron and their decay products, the ingestion of drinking water containing alpha and beta emitting radioactive elements, and exposure to gamma.

Methods

This study used industry radiation emission and occupational exposure to NORM data from three surface lithium mines in Western Australia (WA) for the period between 2018 and 2024. Samples were collected from the lithium ore, spodumene concentrate, tantalum concentrate, wet tailings and dry tailings to determine radioactivity. Exposure to radiation was compared between the departments including Administration and Support Services, Mining, Crushing & Processing, and Maintenance.

Results

The study found a high mean radiation emission in the tantalum concentrate of 2.169 Bq/g. The radiation exposures for all the departments ranged from 0.262 mSv per year to 0.544 mSv year, which were significantly below the occupational dose limit of 20 mSv per year. The study found that the reverse osmosis plants significantly reduced the radiation levels in the bore water after treatment.

Conclusion

The study demonstrated low levels of radiation exposure with the treatment of bore water using reverse osmosis plants. Based on the study results, proactive control measures to protect workers from exposure to tantalum concentrate and the treatment of bore water should be considered.

To address the challenges associated with the recovery difficulties and potential secondary pollution of powdered photocatalysts, this study synthesized a Z-scheme heterojunction g-C₃N₄/TiO₂ (denoted as GT) with a core-shell structure via a hydrothermal method. Subsequently, an efficient and recyclable hydrogel bead was fabricated using sodium alginate and GT as raw materials. The results demonstrated that the hydrogel bead exhibited a remarkable adsorption capacity of 48.79 mg/g for Rhodamine B (RhB) when the GT loading was 0.6 g, significantly surpassing the 26.17 mg/g capacity of GT alone, while also displaying exceptional photocatalytic degradation efficiency. Adsorption kinetic analysis revealed that the adsorption process conformed to the pseudo-second-order kinetic model (R² = 0.976), and isotherm fitting to the Langmuir model indicated monolayer adsorption. Furthermore, the adsorption of RhB by the hydrogel bead was identified as an endothermic process. Under visible light irradiation, the GT(0.6)/CA hydrogel bead achieved a photocatalytic degradation rate of 85.4 % within 100 min for a 100 mL RhB solution with an initial concentration of 40 mg/L, with a degradation rate constant of 0.0205 min⁻¹. The hydrogel bead exhibited outstanding catalytic performance under varying GT loadings, pH conditions, light sources, and synergistic effects, and maintained over 80 % degradation efficiency after five consecutive cycles, demonstrating excellent stability and recyclability. Quenching experiments and electron spin resonance (ESR) analysis further elucidated that the primary active species involved in the degradation process were h⁺ and •O₂⁻. This study provides a novel direction for the development of reusable green photocatalysts.

Hospital wastewater, laden with pharmaceuticals, pathogens, and hazardous substances, poses a significant challenge to conventional treatment methods. Supercritical water gasification (SCWG) emerges as a promising alternative, offering complete sterilization and near-complete degradation of organic pollutants in a single, energy-efficient step, with the added benefit of generating valuable syngas. This compact technology harnesses the unique properties of water above its critical point, enabling rapid oxidation of contaminants and transforming them into syngas and benign products like carbon dioxide and water. Its minimal footprint and streamlined process make SCWG particularly well-suited for on-site integration in hospitals, potentially reducing logistical complexities and environmental impact. This comprehensive review explores the potential of SCWG for hospital wastewater management, examining its feasibility, advantages, limitations, and economic viability. Ultimately, this technology paves the way towards a future where healthcare facilities can achieve both ecological responsibility and unparalleled sanitation, safeguarding both public health and our planet.

Plastic undergoes rapid colonisation in the environment, resulting in the formation of a biofilm necessary for further biodegradation. This study investigates the enrichment opportunities of biofilms formed on polyethylene terephthalate (PET) plastic surfaces incubated in landfill leachate for three months (PL-3), followed by three-month incubation in complex media (PLE1–6 and PLE2–6). The metagenomic analysis of biofilms revealed distinct differences in the microbial community structure. Incubation in leachate (PL-3) resulted in Nitrosomonas prevailing (31.66 %), while biofilms enriched in PLE1–6 and PLE2–6 contained Pseudomonas spp. at 41.89 % and 33.22 %, respectively. Fluorescence in situ hybridisation (FISH) microscopy analysis, using a probe design specific for Pseudomonas spp., was in line with metagenomic data and explored the distribution of this genus in the biofilms. PET bottles weathered under real landfill conditions also contained Pseudomonas spp., but to a lesser extent (10.67 % – 14.52 %) compared to laboratory enrichment. Two weathered PET specimens, sampled at different landfill sites, differed markedly in an abundance of Archaea. The overall enzymatic activity of the biofilm was measured by the fluorescein diacetate hydrolysis assay. By elucidating the impacts of nutrient additives on biofilm formation on PET plastic surfaces, one can gain a deeper comprehension of the mechanisms underlying biofilm development on plastic surfaces. That, in turn, is closely related to plastic biodegradation processes in landfill environments.
