Contamination of aquatic and terrestrial organisms by Perfluoroalkyl substances (PFAS), emerging contaminants, is widespread, as these compounds are present in water, soil, air, and food, owing to their environmental persistence. PFAS exposure induces biochemical process alterations associated with the disruption of the antioxidant defense system in several species. This review aims to discuss how PFAS-induced antioxidant system alterations lead to changes in biochemical processes in different organisms exposed to these pollutants. This disruption, then leads to an imbalance in antioxidant defense systems, contributing to the formation of reactive oxidative species (ROS), which, in turn, can be exacerbate oxidative stress, induce cellular damage, enhance lipid peroxidation, destabilize lysosomal membranes, and cause genotoxic effects, ultimately compromising DNA integrity. In acute tests, PFAS have led to mortality, growth inhibition, diminished behavioral and locomotor abilities, and reproductive impairment. PFAS-induced effects differ with varying species or types of substances, and further bioaccumulation through food chains exacerbates environmental contamination, carrying considerable risks. These findings demonstrate the complex and enduring impact of PFAS on environmental health, emphasizing the importance of this review in corroborating studies on sub-lethal toxicity in exposed organisms and how these effects reflect on the environment. © 2025 Elsevier B.V.

The COVID-19 pandemic, caused by SARS-CoV-2, has emphasized the necessity for scalable diagnostic workflows using locally produced reagents and basic laboratory equipment with minimal dependence on global supply chains. We introduce an open-source automated platform for high-throughput RNA extraction and pathogen diagnosis, which uses reagents almost entirely produced in-house. This platform integrates our methods for self-manufacturing magnetic nanoparticles and qRT-PCR reagents-both of which have received regulatory approval for clinical use–with an in-house, open-source robotic extraction protocol. It also incorporates our "Nanopore Sequencing of Isothermal Rapid Viral Amplification for Near Real-time Analysis" (NIRVANA) technology, designed for tracking SARS-CoV-2 mutations and variants. The platform exhibits high reproducibility and consistency without cross-contamination, and its limit of detection, sensitivity, and specificity are comparable to commercial assays. Automated NIRVANA effectively identifies circulating SARS-CoV-2 variants. Our in-house, cost-effective reagents, automated diagnostic workflows, and portable genomic surveillance strategies provide a scalable and rapid solution for COVID-19 diagnosis and variant tracking, essential for current and future pandemic responses. © 2023, The Author(s).

Peroxymonosulfate (PMS)-based advanced oxidation processes have become promising water treatment technologies in recent years due to the generation ability of powerful oxidative radicals. The redox cycle between transitional metals in heterogeneous catalysis is essential for the continuous activation of PMS, which determines the removal efficiency of organic pollutants. In this work, we first prepared Fe3O4 using precipitation method under alkaline anoxic conditions and subsequently added Ni2+ aqueous solution to synthesize Ni-Fe (hydr)oxide catalysts. Ni-Fe (hydr)oxide catalysts show efficient PMS activation ability, causing the degradation of organic pollutants including trichloroethylene, perchloroethylene, bisphenol A, phenol, and tribromophenol. In Ni-Fe (hydr)oxides/PMS system, nonradical pathway is dominant at the initial stage of the reaction which generates SO5•− and indirectly produces 1O2. In this system, 1O2 and dissolved O2 together participate in the O2 cycling, •OH generation, and electron transfer involving the reduction of Ni(III). The formed Ni(II) reacted with PMS to generate strong oxidative •OH and SO4•− through radical pathway for pollutant degradation. The optimum Ni/Fe ratio of Ni-Fe (hydr)oxide catalysts under the studied conditions was 0.50. Ni-Fe (hydr)oxides show high reactivity and stability in real water matrices, demonstrating Ni-Fe (hydr)oxides are promising catalysts for PMS activation to degrade organic pollutants in contaminated water. © 2022, The Authors.

作者： Bressane, Adriano Pinto, Joao Pedro da Cunha Medeiros, Líliam César de Castro São Paulo State University (UNESP) Institute of Science and Technology São José dos Campos city Brazil Graduate Program in Civil and Environmental Engineering São Paulo State University (UNESP) Brazil

Statement of problem: Green gentrification is an emerging issue, where Urban green space (UGS) upgrades lead to higher living costs, displacing lower-income residents, raising concerns about accessibility, sustainability, and equity. This phenomena challenges the inclusive and equitable development of urban environments. Purpose: Through an integrative analysis of existing literature, this study aims to address a significant gap in current research by exploring how Nature-Based Solutions (NbS) can more effectively counteract the adverse effects of UGS gentrification. Method: Utilizing a scoping literature review, the research analyzes articles from 2015 to 2024 to synthesize insights for a more equitable urban development. Results: Findings reveal diverse lessons learned and strategies for countering green gentrification across different urban settings worldwide. However, a significant number of studies predominantly focus on the Global North, primarily in Europe and North America, which may lead to a regional bias. Practical implications: The results provide insights for policymakers, urban planners, and communities, guiding the creation of more inclusive and sustainable urban green spaces. Future directions: Further research should focus on developing quantitative metrics to evaluate the effectiveness of NbS in mitigating urban gentrification and expanding the geographic focus to include more underrepresented regions. © 2024 The Author(s)

This study investigates the effectiveness of the Cu-doped Bi2O3 method for removing antibiotics. Cu at varying concentrations of 0%, 2%, 4%, 6%, and 8% was used to synthesize Bi2O3 material successfully. The optimal results were obtained by adding 4% Cu to the Bi2O3 matrix. Cu-doped Bi2O3 was characterized by an energy band gap of 2.32 eV, a crystal size of 37.04 nm, and α-Bi2O3 and Rouaite phases. Material containing Cu-doped Bi2O3 was used to degrade antibiotics such as amoxicillin (AMX), ciprofloxacin (CIP), and tetracycline (TC). The various removal techniques investigated include adsorption, photolysis, and photocatalysis. The photocatalytic procedure yielded the highest results in terms of degradation efficiency. The removal efficiency of each antibiotic using the photocatalytic method varies, with AMX at 52.06%, CIP at 61.72%, and TC at 69.44%. Cu-doped Bi2O3 degraded TC-type antibiotics more rapidly, with a reaction rate constant of 0.0065 minutes-1, according to the results of the reaction rate constants. The high removal efficiency and rapid reaction rate indicate that Cu-doped Bi2O3 is an effective antibiotic removal agent, especially for tetracycline-type antibiotics. © 2023, The Authors.

Damage and loss of land resources due to improper land management tend to increase erosion. It will affect the production, ecological, and hydrological functions in the upstream watershed area. However, sedimentation that occurs due to erosion often affects the practical life of the dams. The purpose of this research is to estimate erosion and the distribution of Total Suspended Sediments (TSS) geospatially from Landsat-8 imagery data in 2015 and 2019 for Krueng Pase Watershed. The considerable erosion that occurred in 2014 was 117,987.71 tons. While the erosion that occurred in January 2015 was 18,624.45 tons, and the erosion in August 2019 was 6,672.06 tons. The results of the TSS distribution using algorithms in 2015 obtained the largest total suspended sediment with a value >17.15 mg/l found on the coastal, riverbanks and the smallest TSS with a value of ≤12.73 mg/l found on the upstream area. The TSS were found on the coastal with a value of >16.05 mg/l, and the smallest TSS >12.92 mg/l found on the upstream area in 2019. Information on the distribution of total sediment is a consideration in the application of the eco-hydrology concept as a short-term solution in water management. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Fresh water is needed in industrial activities. For these needs sea water is usually used as raw material if the plant is near the sea and far from the river. SWD (sea water desalination) is used to process sea water to fresh water, that is by reducing levels of salinity or reducing levels of total dissolved solid (TDS). There are two technologies in SWD, namely thermal distillation and reverse osmosis (RO) membrane technology. Residual SWD process or also called blowdown water has high salinity levels can be converted into electrical energy through SGP (salinity gradient power). There are two technologies to capture energy from salinity differences, namely PRO (Pressure Retarded Osmosis) and RED (Reverse Electrodialysis). PRO and RED are renewable energy technology, there are no emision, no moving part, abundant availability in nature and can be recycled. In this article, an analysis for SWD of oil refinery is carried out. From the analysis results it is known that the plant uses thermal distillation technology, requires power as 64.25 MW and 3,403 m3/h seawater to produce 242 m3/h freshwater. With SGP, the potential recovery of power gained is 0.786 MW. This recovery potential is still too small when compared to energy requirements of SWD with thermal distillation technology, but if it use RO technology that only requires 3.6-5.7 kWh/m3 or 0.87 - 1.40 MW to produce 242 m3/h, a significant impack to saving energy will be obtained. © Published under licence by IOP Publishing Ltd.

Performance Evaluation of Sulfidated Nanoscale Iron for Hexavalent Chromium Removal from Groundwater in Sequential Batch Study

SSRN

SSRN 2023年

作者： Bhattacharya, Mainak Barbhuiya, Najmul Haque Singh, Swatantra Pratap Environmental Science and Engineering Department Indian Institute of Technology Bombay Mumbai India Interdisciplinary Program in Climate Studies Indian Institute of Technology Bombay Mumbai400076 India Centre for Research in Nanotechnology & Science Indian Institute of Technology Bombay Mumbai400076 India

Chromium [Cr] contamination in groundwater is one of the serious environmental concerns due to the carcinogenicity of its water-soluble and mobile hexavalent [Cr(VI)] form. In spite of the existence of multiple precipitation and adsorption-based Cr(VI) remediation technologies, the usage of sulfidated nano zerovalent iron (S-nZVI) has recently attracted researchers due to its high selectivity. Although S-nZVI effectively immobilized Cr(VI), its long-term performance in multiple shifted equilibrium has not been explored. In this contribution, a comparative study between conventional nano zerovalent iron (nZVI) and S-nZVI was conducted to investigate their respective efficiencies during repeated usage. First, influences of S-nZVI dosage, initial concentration of Cr(VI), pH, ionic strength, total hardness, sulfate, carbonate, and silicate were probed in ultrapure water. Further experiments were performed in synthetic groundwater to investigate the effects of the initial concentration of Cr(VI) in the pH range of 4 – 8 for 1 g L-1 S-nZVI dosage. The removal rate of Cr(VI) was quantified in groundwater without pH fixation. Finally, a set of sequential batch studies was performed to compare the performance of nZVI and S-nZVI due to repeated usage in Cr(VI)-spiked ultrapure water and groundwater matrices. Mechanistic interpretation of the processes governing the immobilization of Cr(VI) was done by integrating the results of these experiments with the metadata. While aggregation due to magnetic properties and rapid oxidation of Fe decreased the efficiency of nZVI with repeated usage, sulfidation minimized the passivation and favored an extended reducing environment because of continuous electron transfer from iron and sulfur components. © 2023, The Authors.

作者： Tapas, Mahesh Ramesh Etheridge, James Tran, Thanh-Nhan-Duc Le, Manh-Hung Hinckley, Brian Van Nguyen, Tam Lakshmi, Venkataraman Integrated Coastal Sciences Program East Carolina University GreenvilleNC27858 United States Department of Food Agricultural and Biological Engineering Ohio State University ColumbusOH43210 United States Department of Engineering Center for Sustainable Energy and Environmental Engineering East Carolina University GreenvilleNC27858 United States Department of Civil and Environmental Engineering University of Virginia CharlottesvilleVA22904 United States NASA Goddard Space Flight Center Hydrological Sciences Laboratory MD20771 United States Science Applications International Corporation GreenbeltMD20771 United States Helmholtz Centre for Environmental Research – UFZ Saxony 04138 Germany

Accurate flow prediction is crucial in hydrological modeling, influenced by various rainfall datasets, autocalibration methods, and performance indices. This study examines the combined effect of three satellite precipitation products (SPPs) — ERA-5, gridMET, and GPM IMERG — and three autocalibration techniques — DDS, GLUE, and LHS — on SWAT+ river flow prediction using three evaluation metrics — NSE, KGE, and R² — for the Cape Fear and Tar-Pamlico watersheds in North Carolina. Key findings include: (1) Five SWAT+ parameters (cn2, revap_co, flo_min, revap_min, awc) were sensitive across all SPPs and watersheds. (2) Rainfall products significantly impacted simulated river flow more than optimization techniques. (3) GPM IMERG outperformed other SPPs, followed by ERA-5 and gridMET. (4) NSE was more sensitive to SPPs and calibration techniques compared to KGE and R². (5) SWAT+ underperformed in predicting base flow for groundwater-driven watersheds. (6) Optimization techniques can improve flow simulations even for SPPs that are poorly correlated with gauge rainfall data. Overall, our findings suggest that the GPM IMERG rainfall dataset, combined with the GLUE optimization technique, provides the most effective approach for optimal flow simulations. The results from this study will help hydrological modelers choose an optimal combination of rainfall dataset, autocalibration technique, and performance index depending on watershed characteristics. © 2024, The Authors.
