Herein, we reported an electrocatalytic ceramic microfiltration membrane functionalized with CuFe2O4 nanoparticles supported by nitrogen-doped carbon nanotubes (NCNTs). The synergistic catalysis between Fe and Cu induced a continuous ·OH generation. The active Fe(II) and Cu(I) sites decomposed the in-situ generated H2O2 into ·OH. The electron transfer from the external circuit and Cu(I) to Fe(III) drove the regeneration of Fe(II). The interfacial electron transfer from CuFe2O4 to NCNTs decreased the electron density of Fe and Cu, thus facilitating the redox cycles of Fe(III)/Fe(II) and Cu(II)/Cu(I). Furthermore, the Fe and Cu sites at the interface of CuFe2O4 and NCNTs displayed a superior ability to non-interface sites in producing ·OH. At near-neutral pH, the electrocatalytic membrane delivered excellent tetracycline removal kinetics (0.0134 min-1) and significantly alleviated the organic fouling occurring on the membrane. These findings shed new light on the development of new-generation membranes with catalytic oxidation capabilities for water treatment. © 2024, The Authors. All rights reserved.

WetSpass model was applied in this study to simulate and visualize the distribution of groundwater recharge and amount of yearly and seasonal averages groundwater recharge during 2000-2017. The study area covers the Phanom Thuan-Song Phi Nong-Bang Len Operation and Maintenance Projects in western region of Thailand where groundwater has been used as an alternative source of water for irrigation and industrial sectors. The recharge rates performed by WetSpass model were consequently compared with those achieved by empirical relations namely;Chaturvedi Formula (CF), Sehgal Formula (SF), Krishna Rao Formula (KRF), and Bhattacharya Formula (BF). It was exhibited that average rate of yearly groundwater recharge for calibration periods during 2000-2010 was 178.05 mm/yr with RMSE, r2, and d of 48.72 mm, 0.78 and 0.66, respectively. However, average rate of groundwater recharge for validation periods during 2011-2017 was slightly increased which was 186.35 mm/yr with RMSE, r2, and d of 55.09 mm, 0.24 and 0.53, respectively. The simulation result obtained from WetSpass shows that the average annual recharges in the Phanom Thuan, Song Phi Nong, and Bang Len Operation and Maintenance Projects are 22.5%, 22.4%, and 14.8% of average annual rainfall, respectively according to the different soil types. The average groundwater recharges in clay, loam soil, and sandy loam soils are approximately 14.8%, 24.6%, and 25.7% of average annual rainfall, respectively. Moreover, groundwater recharges in dry and wet seasons are quantified as 12.0%, and 88.0% of average annual recharge due to seasonal variation of rainfall magnitudes. © 2020 22nd Congress of the International Association for Hydro-Environment engineering and Research-Asia Pacific Division, IAHR-APD 2020: "Creating Resilience to Water-Related Challenges".

The transformation of mercury(Hg) in the environment plays a vital role in the cycling of Hg and its risk to the ecosystem and human health. Of particular importance are Hg oxidation/reduction and methylation/demethylation processes driven or mediated by the dynamics of light, microorganisms, and organic carbon, among others. Advances in understanding those Hg transformation processes determine our capacity of projecting and mitigating Hg risk. Here, we provide a critical analysis of major knowledge gaps in our understanding of Hg transformation in nature, with perspectives on approaches moving forward. Our analysis focuses on Hg transformation processes in the environment, as well as emerging methodology in exploring these processes. Future avenues for improving the understanding of Hg transformation processes to protect ecosystem and human health are also explored.

Tropospheric ozone (O3) pollution can significantly affect crop yield. O3 concentrations are continuously rising in China. However, the long-term impacts of O3 pollution on crop yield over a long-term period have not yet well quantified due to the limitation of accurate spatiotemporal data and extrapolation methods. Based on a high resolution O3 dataset (HrSOD), here we analyzed the spatiotemporal O3 pollution patterns and their impacts on yield and resultant economic losses for wheat, rice, and maize in China during 2005-2020. Our results showed that daytime O3 concentrations (M7) increased by 2%, and AOT40 increased by 10% during 2005-2019. O3 trends diverged before and after China's 2013 Clean Air Action Plan between the southern and northern regions. Based on the observational data collected from literature and O3 gradient experiments in Asia, we fitted the O3 exposure-yield response curves, and then the relative yield loss (RYL) was assessed. Rising O3 pollution reduced national level wheat, rice and maize yields by 12.94-15.52%, 8.91-14.67%, and 4.13-4.9%, respectively, during 2005-2020. The O3-induced yield losses showed large spatiotemporal variations with higher losses in the northern China. Mean annual crop production losses reached 16.48 million tonnes (Mt) for wheat, 22.84 Mt for rice and 9.42 Mt for maize. The corresponding economic losses were USD 5.53 billion for wheat, 10.52 billion for rice and 1.70 billion for maize. While O3 declined across the southern China and the Tibetan Plateau, the northern China has witnessed an increased pollution and crop damage, highlighting the need for targeted mitigation policies in the northern China. Reduced O3 during 2020 COVID-19 lockdown period alleviated crop yield losses, demonstrating that curbing emissions could lessen damage. This long-term and high-resolution analysis provides robust evidence that rising O3 pollution has substantially affected China's staple cereal yields, causing considerable production an

作者： Yang, Chat How Joewin Koh Liu, Guicai Chan, Wei Ping Zhao, Ya Liu, Wen Lim, Teik Thye Lisak, Grzegorz Residues and Resource Reclamation Centre Nanyang Environment and Water Research Institute Nanyang Technological University Singapore637141 Singapore Interdisciplinary Graduate Program Nanyang Technological University 1 Cleantech Loop Cleantech One Singapore637141 Singapore School of Chemistry Chemical Engineering and Biotechnology Nanyang Technological University Singapore637459 Singapore School of Civil and Environmental Engineering Nanyang Technological University Singapore639798 Singapore

The utilization of water treatment sludge (i.e., ferric sludge) was explored as the oxygen carrier (OC) for chemical looping combustion (CLC) of municipal solid waste (MSW) syngas. The performance of ferric sludge (FS) in CLC and simultaneous HCl removal was evaluated in a bench-scale fluidized bed, and was compared with iron ore (IO) as a benchmarked OC. The results show that FS (92%) performed better than IO (82%) in terms of syngas combustion efficiency and FS was able to remove HCl (77% removal efficiency) while IO was unable to remove any HCl. Comparison of reaction temperature reveals that FS performed better at lower CLC temperature between 800 °C and 850 °C. Agglomeration was observed when FS was used in extended CLC cycles. Thus, investigation of using inert a-Al2O3 support together with FS for extended CLC cycles was investigated. Agglomeration and sintering were drastically reduced and good combustion efficiency of 88% for H2 and 74% for CO was attained. Carbon footprint assessment illustrated that FS was superior as a greener material based on global warming potential of 20 and 100 years. Conversion of FS as an OC were characterized with 104.23 and 108.0 kgCO2/t lower than IO for GWP-20 and GWP-100, exhibiting the competitiveness in the usage of waste-derived material in CLC. Hence, FS can be considered as a novel, cost-effective, and greener OC for CLC. The co-utilization of waste-derived material and waste-derived syngas through CLC would be an integrated solution for improved circularity and sustainability. © 2023, The Authors.

Detecting Bacterial Leaf Blight (BLB) in paddy fields is one of the essential issues in Indonesia to prevent losses in rice production. This study reports the effectiveness of textural analysis using drone-acquired data over paddy fields in West Java, evaluating the potential of integrating textural and thermal characteristics. We used drone data combined with machine learning techniques to distinguish different levels of BLB impact. The normalized difference texture index derived from Haralick textural features was used as a predictor. The findings revealed that incorporating textural features enhanced the disease detection accuracy significantly compared with the traditional approach based on spectral indices. The random forest algorithm, which merges texture and vegetation indices, achieved a classification accuracy of 0.984. The proposed method offers a robust, noninvasive solution for BLB disease detection, contributing substantially to safeguarding crop yields and mitigating global food security issues. © 2024, The Authors.

Interactions between groundwater and surface water sustain groundwater-dependent ecosystems, provide baseflow to rivers, and regulate river temperature and biogeochemical cycles, amongst many other processes. These interactions occur in freshwater environments including rivers, springs, lakes, and wetlands, and in coastal environments via tidal pumping, submarine groundwater discharge, and seawater intrusion. Here, we use a data-driven approach to explore groundwater-surface water interactions research using 20,275 journal papers published between 1970 and 2023. Analyses show that research into groundwater-surface water interactions is highly multi-disciplinary, with growing contributions from the social and biological sciences. As in the case with many research areas, the number of groundwater-surface water interactions papers is rapidly increasing with over 1200 papers published per year since 2020. Drawing on our data-driven approach and expert knowledge, we synthesise current research trends and identify critical future research directions. Despite the thousands of papers on groundwater-surface water interactions, there are still important processes that are difficult to quantify or predict at meaningful spatial scales to inform management. We see benefits in future groundwater-surface water interactions research focusing on: (1) embracing new technologies including the use of internet-of-things-based sensors and further use of uncrewed vehicles in data capture and remote sensing approaches to inform groundwater-surface water interactions at large scales, (2) capitalising on the increased computational power, availability of physically based models, and machine learning to inform hydrological and biogeochemical processes, and (3) continuing the movement towards multi-disciplinary investigations to better inform the quantification of groundwater-surface water interactions that will enable better management outcomes. © 2024, The Authors.
