However, farming faces challenges from environmental stress and diseases that reduce crop quality and quantity. Traditional methods, such as pesticides and fertilizers, though effective in boosting crop yields, can harm the environment and leave residues. Nanotechnology is presently being investigated in agriculture to overcome these challenges, as nano-fertilizers can release nutrients gradually over a longer period of time, minimizing nutrient loss and enhancing crop uptake efficiency. The purpose of this paper is to provide a comprehensive synthesis and analysis of the impact of nanofertilizers on crop yield and nutritional quality, as well as to elucidate the mechanisms underlying their effects on crops. This analysis aims to provide insights into the revolutionary potential of nanofertilizers in improving crop yields by examining the subtle interplay between nanotechnology and agricultural practices while ensuring the safety and nutritional integrity of agricultural output.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"14 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660535","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}

To better assess ecological risks associated with water reuse, a profound knowledge on the sorption of OMP to soils and how it is affected by varying matrix properties is essential. This study evaluates the sorption characteristics of ten OMP — including pharmaceuticals (carbamazepine, diclofenac, primidone, sulfamethoxazole, valsartan acid), artificial sweeteners (acesulfame, saccharin), and the corrosion inhibitor benzotriazole — in an agricultural soil under variable ionic strength (0, 0.03, and 0.3 mol L⁻¹), cation valence (Na⁺ vs. Ca²⁺), and pH conditions (equilibrium pH vs. pH 7.5). In batch experiments, sorption of most OMP showed a bell-shaped response to increasing ionic strength (IS) with CaCl₂, with peak sorption observed at moderate IS (0.03 mol L⁻1) and reductions at higher IS, suggesting cation bridging effects and competition dynamics. Additionally, anionic OMP exhibited significantly reduced sorption at higher pH (7.5) due to increased electrostatic repulsion. Linear sorption coefficients (K_d) varied by up to a factor of six across treatments, with stronger effects observed in the topsoil layer, caused by higher organic carbon content. Altogether, the findings of this study highlight the need to consider solution chemistry and specific matrix effects to improve the prediction quality of OMP transport and retention in agricultural soils. The results underline that grouping OMP solely by charge may not suffice for risk assessment, as sorption behaviors are highly substance and soil-specific.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 4","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-025-07885-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, this work aims to through light on the mineralogical and geochemical composition of Geziret El Nabatat soil, for the first time. Mineralogically, the soils of Geziret El Nabatat consist of quartz, montmorillonite, kaolinite and calcian-albite, which nearly follow up the composition of the Nile Valley soil. The prevailing oxides in this soil are SiO₂, Al₂O₃, Fe₂O₃ and CaO with mean concentration 49.04%, 13.62%, 13.02% and 5.57%, respectively. The mean concentration of potentially toxic elements (PTEs); Pb, Co, Cr, Cu, Ni and Zn was 13.64, 17.33, 42.89, 33.68, 49.65 and 63.48 mg/kg, respectively.

But little is known about their contamination and bioaccumulation in plants. In this study, bioaccumulation of 11 PHCZs, carbazole (CZ) and benzocarbazole (BZCZ) from soil to plant was investigated by paired soil-earthworm samples from Hangzhou, China and a laboratory bioaccumulation test. ∑₁₁PHCZs, CZ, and BZCZ in herbs were 1.9–247.1 ng/g dry weight (dw), &lt; LOQ–6.1 ng/g dw, and not detectable–265.2 ng/g dw, respectively. The cos θ parameters (above 0.8) support the similarity of PHCZ patterns between soil and plant, which suggests the importance of soil-related uptake into plants. The Kruskal–Wallis H test (<i>p</i> &gt; 0.05) and cos θ (0.706–0.998) indicated a lack of species-specific distribution. The bioconcentration factors (BCFs) for CZ, BZCZ, and PHCZs were 0.21, 3.62, and 0.08–10.52, respectively. 2,3,6,7-tetrachlorocarbazole, 2,7-dibromocarbazole, and 1,3,6,8-tetrabromocarbazole (1368-BCZ) are bioavailable in herbs, whereas CZ and 3-bromocarbazole are not. The negative correlations between BCFs and soil concentrations provide evidence of a kinetic limitation of accumulation at higher exposure levels. The correlation analysis indicated the potential influences of K_OA and K_OW on the transfer of PHCZs from soil to plants. The laboratory test indicates the bioaccumulation of 3,6-dicholorcarbazole and 1368-BCZ from soil to plant and the contribution of soil-root pathway based on the soil-tissue bioconcentration factors. The mass balance model suggests a predominance of the soil-root-leaf pathway compared to the soil-air-leaf pathway.

Unfortunately, if not operated properly, MAR can cause undesirable arsenic mobilization in groundwater. To avoid unexpected arsenic mobilization, we need a better understanding of the evolving water chemistry and nanoscale mineral–water interfaces in MAR systems. Bicarbonate is a ubiquitous groundwater component, but its effect on arsenic mobilization in MAR is not fully understood. Hence, we examined the effects of bicarbonate concentrations (0.01 mM, 0.1 mM, 1.0 mM, and 10 mM) on the dissolution of arsenopyrite and the nanoscale secondary mineral formation in both open systems (mimicking shallow unconfined aquifers) and closed systems (mimicking deep confined aquifers) over 7 days. In the open system, owing to pH evolution and the subsequent formation and growth of iron (III) (hydr)oxide nanoparticles, the arsenic mobilization decreased with increasing bicarbonate concentrations. However, the increase from 1.0 to 10 mM formed surface complexation and aqueous arseno-carbonate complexes and did not further reduce the arsenic mobilization. In the closed system, arsenic mobilization and iron (III) hydr(oxide) nanoparticle formation were similar for all conditions. This study highlights bicarbonate-controlled nanoparticle formation and arsenic mobilization in MAR systems, providing valuable insights for enabling safer and more sustainable MAR operations.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"55 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640252","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}

Among various heavy metals, Arsenic (As3+) or arsenite is one of the most toxic ions present in ground water. Long-term exposure to arsenic-contaminated water triggers a number of health hazards including lung cancer, and harm the liver and kidneys. Therefore, detection of this heavy metal in water samples is of paramount importance. Herein, we have synthesized citrate-stabilised GdVO4:Eu3+ downconverting nanophosphors (DCNP) with a facile hydrothermal process and studied them as an efficient photoluminescence probe for highly selective and sensitive detection of As3+ ions in water. The energy transfer from the vanadate group (VO43-) to the lanthanide-dopant (Eu3+) causes these nanophosphors to exhibit sharp, strong and steady luminescence emission upon excitation in the Uv-Visible range. Since As³⁺ is predominantly detected in the form of HAsO₃²⁻ in aqueous environment under neutral to slightly basic conditions in this work, during the detection process it selectively binds covalently to the Eu-OH present on the DCNP surface, resulting in the quenching of sharp DCNP emission. Other metal ions were found to have much lesser quenching effect due to their non-selectivity. The detection limit (LOD) was found out to be as low as 0.039 µM (39 nM), which is much lower than the WHO allowed contamination levels of As3+ in drinking water (0.13 µM). This nanosesnor can efficiently detect As3+ in a wide range of pH. Further, as interfering ions do not influence the detection process, this is a promising approach for the selective and sensitive detection of As3+ ions in complex aqueous specimen.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"69 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640253","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}

Water samples were collected from the Arroio Dilúvio in Porto Alegre, RS. A factorial design using central composite design (CCD) was conducted to determine the influence of variables such as pH, time, and gas dosage on the mineralization of the matrix, considering two gas flow rates (0.5 and 1.0 L/min). It was observed that integrating ozonation resulted in an average 25% reduction in coagulant concentration through pre-ozonation, highlighting the benefits of this approach for treating contaminated matrices. Furthermore, it led to increased mineralization at both flow rates (0.5 and 1.0 L/min), achieving final values of 33.2% and 39.0%, respectively (pH 8, 30 min, and coagulant concentration 60 mg/L). Regarding intermediate ozonation, mineralization reached values of 59.0% (pH 8, 30 min; 0.5 L/min) and 83.0% (pH 10, 15 min; 1.0 L/min). The latter not only highlights the effectiveness of the integrated process but also its potential to optimize the operation of more sustainable treatment.
