Peralta-Videa, Lijuan Zhao","doi":"10.1039/d4en00685b","DOIUrl":"https://doi.org/10.1039/d4en00685b","url":null,"abstract":"Rice is highly susceptible to salt stress. Increasing the salt tolerance of rice is critical to reduce yield loss. Herein, we investigated the possibility of using an AgNP-based priming method (seed soaking (SP) and leaf spraying (LP)) to enhance rice salt tolerance. Under saline conditions, both SP (40 mg L<small>⁻¹</small>) and LP (∼0.15 mg per plant) significantly increased the biomass (10.4–13.4%) and height (6.6–6.9%) of 6-week-old rice seedlings. In addition, SP significantly increased chlorophyll a (7.3%) and carotenoid (7.9%) content as well as total antioxidant capacity (10.5%), whereas it decreased malondialdehyde (MDA) content (16.9%) in rice leaves. These findings indicate that AgNP priming, especially SP, improved the salt tolerance of rice seedlings. A life cycle field study conducted in a real saline land revealed that SP significantly increased the rice grain yield by 25.8% compared to hydropriming. Multi-omics analyses demonstrated that AgNP priming induced metabolic and transcriptional reprogramming in both seeds and leaves. Notably, both SP and LP upregulated osmoprotectants in seeds and leaves. Furthermore, several transcriptional factors (TFs), such as WRKY and NAC, and salt-tolerance related genes, including the high-affinity K<small>⁺</small> channel gene (OsHKT2;4, OsHAK5), the Ca<small>²⁺</small>/proton exchanger (CAX4), and the cation/Ca<small>²⁺</small> exchanger (CCX4), were upregulated in leaves. Omics data provide a deep insight into the molecular mechanisms for enhanced salinity tolerance. Together, the results of this study suggest that seed priming with AgNPs can enhance the salt tolerance of rice and increase rice yield in saline soil, which provides an efficient and simple way to engineering salt-tolerant rice.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142489509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their potential, research has largely been limited to laboratory-scale experiments, with few studies exploring pilot-scale applications. This study investigates <i>pine cones</i>, a novel and underutilized waste material, as a bio-coagulant for wastewater treatment plants (WTPs). The active coagulating agent was extracted from <i>pine cones</i> treated with a 0.5 M sodium chloride (NaCl) solution. Characterization was performed using Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), and chemical analysis, revealing significant quantities of coagulating agents responsible for effective coagulation. A jar test was initially conducted to determine the optimal coagulant dosage, initial pH, and settling time for the coagulation-flocculation process. The process was modeled and optimized for turbidity, chemical oxygen demand (COD), and phosphate removal using response surface methodology (RSM) with a Box Behnken design (BBD). The optimal conditions identified were a 10 ml/L coagulant dosage at pH 10 and a settling time of 115 min. Experimental data and model predictions showed good agreement, with R² values of 99.12%, 93.52%, and 98.11% for turbidity, COD, and phosphate removal, respectively. Jar tests under these conditions achieved removal efficiencies of 98.81%, 72.02%, and 86.44% for turbidity, COD, and phosphate. The optimized conditions were then applied on a pilot scale, showing removal efficiencies of 97.77%, 71.35%, and 88.6% for turbidity, COD, and phosphate.

In this investigation, we present an innovative and streamlined methodology to address the constraints encountered in the fabrication of biomass-derived Graphene Foams (bGFs). Our primary focus is on customizing their extensive surface area and structural attributes to align with the specific requirements of environmental applications, particularly for the adsorption of chlorophenols. We developed a distinctive BGF with a highly porous, spongy structure and an impressive specific surface area of up to 805 m²/g through a two-step synthetic process. Our method not only enhances the environmental applicability of BGFs but also demonstrates their superior adsorptive capabilities. The adsorption performance of the BGFs was rigorously evaluated, with a focus on capacity, kinetics, and the influence of pH. Comprehensive studies on the effects of pH, contact time, adsorbent dosage, and phenolic content were conducted. The adsorption isotherms for DCP and TCP adhered to the Langmuir model, revealing an outstanding adsorption capacity of 245 mg of pollutant per gram of BGF at an optimal pH of 3–4. Remarkably, BGFs reduced the concentration of phenolic derivatives in water to levels below the World Health Organization’s acceptable limit for human use (0.050 mg/dm³). This research highlights the significant potential of Bio-Graphene Foams as highly effective adsorbents for environmental remediation.

This research extends existing studies that seek to understand the SIDS-specific challenges to accessing international public climate finance by developing a new explanation based on data collected via a multi-methods research design which draws on interviews with SIDS negotiators and officials, surveys, and roundtables, as well as content analysis of GCF and UNFCCC documents. Drawing on ideas about the social construction of scale and the emerging literature on the financialization of international development funding, we argue that SIDS’ limited access to climate funding from the GCF is the consequence of assumptions in development models of the benefits of largeness, with largeness equated with value for money. The perceived advantages of large-scale programs compound the injustice of climate change for SIDS, whose communities have contributed little to the problem yet struggle to gain access to meaningful levels of assistance.

Nevertheless, scarcely any studies have been conducted on the effect of soil pH changes on the environmental behavior of sulfamethoxazole. To investigate the impact of different pH levels on the migratory mechanisms and degradation pathways of SMX within soil systems, indoor soil column leaching experiments were conducted. Ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF–MS) were used to analyse the dynamic changes in the content of SMX as well as to identify its degradation products. The results showed that acidic conditions constrained the vertical migration of antibiotics in the soil. These transformations ensued through a sequence of reaction processes, encompassing ring opening, hydroxylation, S-C bond breaking, and the oxidation of aniline groups. The study of the migration and transformation of sulfamethoxazole under different pH conditions can lay a solid theoretical foundation for the assessment of the pollution risk of sulfamethazine degradation products under acid rain and salt and alkali conditions, so as to better prevent and protect underground water resources.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
