Bismuth sulfide (Bi 2 S 3 ) aerogel, synthesized via a one-step hydrothermal method, demonstrates exceptional iodine adsorption performance. Characterization by scanning electron microscopy (SEM) and BET confirmed the material’s porous structure, which facilitated iodine uptake. Batch experiments revealed a high adsorption capacity of 1,204 mg/g, with kinetics and isotherms well described by the pseudo-second-order model and Freundlich isotherm, respectively, indicating that the adsorption process is dominated by chemisorption. The adsorption mechanism involves iodine phase transfer and subsequent formation of stable BiI 3 phases, ensuring long-term immobilization. The Bi 2 S 3 aerogel demonstrates superior chemical and thermal stability, high capture efficiency, and cost-effectiveness, further highlighting its practical potential for nuclear waste management. This work advances the design of bismuth-based adsorbents by combining high capacity, stability, and scalable synthesis, thereby offering a sustainable solution for radioactive iodine capture.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://public-pages-files-2025.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2025.1709936/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

This study investigates the impact of aging on the retention and remobilization dynamics of polystyrene (PS) microplastics in unsaturated porous media. We employed light-aged PS MPs and conducted column experiments using sea sand under multiple wetting-drying cycles. Key physicochemical properties of the MPs were characterized, and their retention and remobilization were quantified by monitoring effluent concentrations.Aging significantly altered MP properties, increasing their surface negative charge and hydrophilicity. Consequently, aging suppressed the remobilization of retained MPs during drying phases. After five cycles, the total retained fraction of aged MPs (76.88%) was consistently higher than that of pristine MPs (72.83%). Remobilization was primarily driven by mobile air-water interfaces (AWI) once water saturation fell below a critical threshold of approximately 0.6. Although aging increased electrostatic repulsion (which hinders retention), it also increased hydrophilicity, which significantly weakened AWI-driven remobilization during drying. This retention-promoting mechanism (reduced AWI remobilization) outweighed the opposing effect of electrostatic repulsion, leading to greater overall retention of aged MPs. This study highlights the complex regulatory role of aging on MP fate and provides critical insights for assessing the environmental risks of aged microplastics in dynamic unsaturated systems.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2025.1639535/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147890993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

This study investigated the individual and combined toxic effects of triphenyltin (TPT, 1 μg/L) and microplastics (MP, 0.5 mg/L) on oxidative stress, energy metabolism, and digestive function in Cyprinus carpio over a 42-day exposure period. The results demonstrated that TPT and MP combined exposure significantly reduced glutathione (GSH) activity, enhanced the activity of inflammatory factors (IL-1β) and upregulated the expression of antioxidant and inflammatory genes ( gpx and il-1β ) comparing with the control group in the liver, indicating severe oxidative stress. Combined exposure exhibited complex interactive effects, potentially involving adaptive or antagonistic mechanisms. Regarding energy metabolism, TPT and MP inhibited Na + /K + -ATPase activity, disrupting ion balance in the gills, whereas combined exposure promoted the expression of genes related to fatty acid metabolism ( cpt1 and lpl ). The combined exposure led to a partial restoration of ion pump activity, which implies the existence of a compensatory mechanism. TPT and MP exerted an inhibitory effect on the activity of digestive enzymes in the intestines, while they triggered a compensatory reaction by upregulating the expression of digestive enzyme genes. The combined exposure vividly unveiled the complex and intertwined interactions between the inhibitory and adaptive responses, highlighting the multifaceted nature of the biological impacts under such combined stressors. This study provides essential insights into the combined toxicity of TPT and MP, highlighting their ecological risks and underscoring the need for improved environmental monitoring and management strategies.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2025.1614013/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147334200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Several heavy metals (HMs), such as Pb, Cd, Cr, Cu, and Ni, are major anthropogenic pollutants that cause severe environmental pollution. The accumulation of these toxic HMs in soils has raised several concerns for crop growth, food safety, and marketing. Physiological and biochemical processes in plants are severely impacted by HMs, disrupting normal metabolic activities and reducing biomass production. Phytoremediation plays a pivotal role in addressing HM contamination by offering an eco-friendly, economical, and holistic solution. Similarly, arbuscular mycorrhizal fungi (AMF) play a significant role by forming a symbiotic relationship with plant roots. In this association, plants provide root exudates, while AMF enhance plant growth under heavy metal stress by supplying essential nutrients, minerals, and water. These fungi also improve nutrient status, soil quality, and ecosystem stability. The present review and meta-analysis encompass an examination of the global distribution of toxic HMs in mining-affected areas. Furthermore, the study highlights the role of various plant species and microbes, particularly AMF, in mitigating HM stress and its impact on plant growth and nutrition. The meta-analysis also evaluates the efficacy of AMF as a remediation strategy for HM-impacted mine soils.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2024.1532169/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Recently, the excessive discharge of goat manure has resulted in groundwater environmental challenges and negative impacts. It is of practical significance that such wastes can be converted into functional materials to promote the resource utilization of waste and reduce the risk of antibiotic contamination. In this study, Fe (Ⅱ)-loaded goat manure biochar (Fe-GMC) was prepared by pyrolyzing goat manure and iron salts and used to activate peroxymonosulfate (PMS) for tetracycline (TC) degradation in groundwater. The as-prepared Fe-GMC exhibited good catalytic performance for PMS activation due to its porous surface and rich oxygen-containing groups. Under the conditions of catalyst dosage of 0.2 g/L, PMS dosage of 1.0 mM, and pH of 3.0, TC was removed 81.3% within 60 min. In addition, the TC degradation efficiency was inhibited to different extents by inorganic anions (HCO 3 − &amp;gt;Cl − &amp;gt;NO 3 − ) in water. Furthermore, the quenching experiments, electron paramagnetic resonance (EPR) experiments, and X-ray photoelectron spectroscopy (XPS) spectra analysis indicated that the generation of hydroxyl radicals ( • OH) was responsible for TC degradation. Particularly, Fe-GMC produces a strong oxidizing agent. This study provides an efficient and environmentally friendly tetracycline degradation catalyst, which offers a new theoretical basis for water environmental remediation.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2024.1467797/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147901902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

This is the most severe episode ever recorded in the country. Seventy people were injured, resulting in one fatality; several buildings were severely damaged, which resulted in substantial financial losses (more than €6M). Methods In the present study, we analyze the stones collected during fieldwork to gather information on their growth processes. This analysis was conducted considering two lines of investigation. In this paper we focus on the innovative and never-before-used technique of the Computed Tomography Scan, which was utilized to analyze hailstones and their interiors, the outcomes were groundbreaking. It makes it possible to obtain a complete 3D view of the interior of the stone, without producing any alteration in the structure. Through this technology, the different layer densities have been quantified. This is the main novelty of the study and opens a promising door to more analyses in this field. Results The analysis has revealed some interesting results that help to verify previous theories. For instance, the nuclei can be placed far from the stone center, even if the hailstone is externally spherical. Discussion Besides, a thicker hailstone layer in one direction indicates the falling direction. Finally, the different layer densities show growth process variations.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2024.1479824/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Recently, microbial-derived organic matter have been recognized as essential components of stabilized soil carbon pools. However, the contribution of microbial-derived organic matter to sorption of organic contaminants remains unclear. Methods Here, we obtained microbial-derived organic matter-mineral composites by inoculating model soil (a mixture of hematite and quartz sand (FQ) or montmorillonite and quartz sand (MQ)) with natural soil microorganisms and different substrate-carbon (glycine (G), glucose (P), or 2, 6-Dimethoxyphenol (B)), which were named GF, PF, BF, GM, BM, and PM, respectively. Batch sorption/desorption experiments were conducted for phenanthrene (PHE) and ofloxacin (OFL) on the composites. Results and Discussion The composites cultured with 2,6-dimethoxyphenol had the highest carbon content (0.98% on FQ and 2.11% on MQ) of the three carbon substrates. The carbon content of the composites incubated with MQ (0.64%–2.11%) was higher than that with FQ (0.24%–0.98%), indicating that montmorillonite facilitated the accumulation of microbial-derived organic matter owing to its large specific surface area. The sorption of PHE by microbial-derived organic matter was mainly dominated by hydrophobic partitioning and π-π conjugation, whereas the sorption of OFL was mainly dominated by hydrophobic hydrogen bonding and π-π conjugation. The sorption of OFL onto the composites was more stable than that of PHE. Microbial-derived organic matter -mineral composites can reduce the risk of organic contaminant migration in soil, particularly ionic organic contaminants.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2024.1485328/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147919943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Nutrients in this runoff are dominated by fresh animal deposits, but recent dairy and beef farm studies showed that available phosphorus (P) accumulates in roadway surface material and can be lost in runoff. A current knowledge gap is to examine available P concentrations in unsealed roadway and trackway (non-maintained) network of a lowland sheep farm. The present study focused on a 45 ha farm stocked with 544 sheep in south-east Ireland. Ten locations were sampled along with the adjacent fields for available P (i.e., Morgan’s P) and ancillary parameters (e.g., pH, total P and heavy metals) in December 2022. The first sampling location was on an aggregate roadway and the other nine were on trackways representing an older aggregate roadway network used by the flock but now covered with soil and grass. Results showed a distinct difference in surface material pH between roadway and trackway locations. Trackways had a pH that mimicked adjacent fields around the agronomic optimum for grassland of ∼6.2. All sampling locations had elevated available P concentrations, ranging from 26.3 to 111.0 mg L<jats:sup>−1</jats:sup> (mean 62.8 mg L<jats:sup>−1</jats:sup>), similar to the spatial distribution for dairy farms but above those found at beef farms previously studied. The highest available P concentrations were found in roadway and trackway sections adjacent to the farmyard. Other elevated sampling areas were on trackways (87.3 or 97.7 mg P L<jats:sup>−1</jats:sup>) away from the farmyard where sheep are funnelled to pasture, stop to seek shade, urinate and defecate but do not graze. By contrast the average available P concentration for the surrounding fields was 8.4 mg L<jats:sup>−1</jats:sup> with a range of 2.7–15.9 mg L<jats:sup>−1</jats:sup>. Two sampling areas combine to create a critical source area where a high available P source becomes visibly mobilised as runoff during rainfall, discharges into an open drainage ditch, which is then connected to a local stream. Breaking the pathway before runoff enters the open ditch could be a cheap and effective way of mitigating nutrient losses at these two locations.","PeriodicalId":12460,"journal":{"name":"Frontiers in Environmental Science","volume":"3 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
