A recent UN Sustainable Development Goals(SDGs) analysis indicated a significant regression in the global SDG goal scores, particularly in SDG 2—Zero Hunger. The emissions of environmental pollution caused by meeting food demands have prompted some countries to intensify their climate change mitigation efforts. These circumstances have introduced significant uncertainty to the future global sustainable food development. Additionally, a notable global challenge is the persistence of hidden hunger, primarily characterized by the insufficient consumption of high-quality animal protein. Addressing this issue would necessitate increased environmental costs to attain high-quality food security. The future food system presents a significant challenge in coordinating food security, food quality and environmental quality. This article presents a comprehensive review and proposes a three-step strategy for future agricultural development based on food security, quality, and environmental aspects. This is a novel food system transfer strategy, as it concurrently addresses both global food security and environmental thresholds. It involves the construction of an efficient food system that operates within the constraints of environmental limits. The objective is to align with global SDG indicators and to maintain natural resource consumption and pollutant emissions within planetary boundaries.

The Hanjiang River occupies a very important position in China's water resource allocation and is a typical dam-influenced river in China. To monitor the water quality and heavy metal content of the river, and to investigate the influence of water hubs on the changes of both, sampling sites were set up in October 2020 upstream, before, and below the dams of three typical water hubs in the middle reaches of the Hanjiang River for analysis and investigation. The results showed that the concentrations of TP, TN, NH4-N, and Fe exceeded the standard;the concentrations of conventional water quality indicators changed significantly (P 0.05). © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Trade-Off between Sulfidated Zero-Valent Iron Activity and Stability: Regulation of Iron Sulfides by Ammonium Dihydrogen Phosphate

作者： Zhang, Yanshi Li, Fengmin Wang, Xiao Zhao, Chengxuan Zhang, Yiqiao Wang, Chunguang Li, Yanlu Xu, Chunhua Shandong Key Laboratory of Water Pollution Control and Resource Reuse School of Environmental Science and Engineering Shandong University Qingdao266237 China State Key Lab of Crystal Materials Shandong University Jinan250100 China

The reactivity and stability of zero-valent iron (ZVI) and sulfidated zero-valent iron (S-ZVI) are inherently contradictory. Iron sulfides (FeSX) on the S-ZVI surface play multiple roles including electrostatic adsorption, catalyzing reduction, and acted as protective layer and reaction platform. We proposed to balance the reactivity and stability of S-ZVI by modulating iron sulfides. Benefiting from the superior coordination and accelerate electron transport capabilities of phosphate, environmentally friendly ammonium dihydrogen phosphate (ADP) was employed to regulate the FeSX in this study. Therefore, the N, P, and S-incorporated ZVI (NPS-ZVI) was prepared by liquid-phase precipitation using ADP as the nitrogen and phosphorus source. Raman spectra, FTIR, XPS, and density functional theory (DFT) calculations were combined to reveal that NH3 and HPO42- act as the main N and P species on the Fe surface, respectively. The superior reactivity of NPS-ZVI was quantified by different parameters (kobs, kSA, kM), which were 210.77, 27.44, and 211.17-fold than ZVI, respectively. Compared to S-ZVI, NPS-ZVI demonstrated excellent pH tolerance and reusability, and there was no risk of secondary pollution. Critically, NPS-ZVI could effectively maintain FeSX stability under the combination of diffusion limitation and surface protection mechanisms of ADP which demonstrated excellent long-term stability. The superior reactivity of NPS-ZVI was attributed to that ADP maintains FeSX stability and accelerates electron *** study provides a novel strategy in balancing the reactivity and stability of S-ZVI and offers theoretical support for material modification. © 2024, The Authors.

Deciphering Heterojunction Layered Double Hydroxide-Polyaniline-Carbon Nanotubes for Phosphorus Capture in Capacitive Deionization

The capacitive deionization (CDI) has emerged as a robust technology due to its effective performance in removing and recovering phosphate in wastewater. However, there are still challenges in achieving fast charge transfer and high capacity phosphorus storage simultaneously. In this study, a novel layered double hydroxide-polyaniline-carbon nanotubes composite material (ZnFe-PANI/CNT) with heterojunction and pseudocapacitive characteristics was fabricated via a simple and effective precipitation strategy. The existence of heterojunction and pseudocapacitance of ZnFe-PANI/CNT was confirmed through material performance testing Moreover, with its fast charge transfer and high ion storage performance, it was achieved high phosphate adsorption efficiency (94%) and sustainable electrode regeneration in low concentration phosphate wastewater. Ultraviolet photoelectron spectroscopy (UPS) and density functional theory revealed the ability to accelerate charge transfer, which was contributed by the heterojunction ZnFe-PANI/CNT. In addition, it was found that the synergies of electrostatic attraction, ligand exchange and surface complexation contributed to the high phosphate capture ability in the acidic environments. The binuclear bidentate or mononuclear bidentate structures dominated the surface configuration of phosphate adsorption at pH 4–9. © 2024, The Authors. All rights reserved.
