Recent advancements have focused on developing nanocomposite and organic-inorganic hybrid membranes, integrating materials like graphene oxide, silica, and carbon nanotubes to enhance mechanical strength, thermal stability, and chemical resistance. These innovations have yielded remarkable results, such as achieving 77.9 % energy conversion efficiency and current densities of 1000 mA/cm² in seawater electrolysis systems. Additionally, advanced IEMs demonstrate significant improvements in selective ion removal, with lithium recovery efficiencies reaching 93 % and fluoride reduction below WHO guidelines. Despite these successes, challenges like fouling, chemical degradation, high costs, and scalability barriers remain. Future research directions emphasize sustainability, with a focus on biopolymer-based membranes, renewable energy integration, and computational modeling. By addressing these challenges, IEMs can significantly contribute to global environmental sustainability and resource efficiency. IEMs are vital in energy generation, enabling ion transport in fuel cells (PEMFCs, AEMFCs) for clean energy, redox flow batteries (VRFBs) for efficient energy storage, and electrolyzers (PEMELs, AEMELs) for hydrogen production. They also support salinity gradient power in reverse electrodialysis (RED) and pressure-retarded osmosis (PRO) and facilitate CO₂ electroreduction (CO₂RR) for carbon-neutral fuel production. This review (covering 2020–2024 publication years) explores recent developments in IEM technology, highlighting their applications, challenges, and future prospects in addressing global environmental and industrial challenges.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"377 ","pages":"Article 144327"},"PeriodicalIF":8.1,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683895","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}

Due to the bioactivity by which they kill and prevent bacterial growth, ERY and other antibiotics may have significant unwanted impacts on the gut microbiome of fishes. The overall objective of this project was to assess effects on the gut microbiome in response to exposure to ERY alone or in a mixture with other common antibiotics, which was accomplished in two experiments. The objectives of experiment 1 as a pilot study were to understand uptake and depuration of ERY in juvenile rainbow trout (RBT) over a 7-d exposure to three concentrations of ERY followed by a 7-d depuration period. Furthermore, throughout the study changes in gut microbiome were assessed. In experiment 2, an identical experimental design was used to assess the effects of a mixture of antibiotics containing, in addition to ERY, 100 μg/g each of ampicillin, metronidazole, and ciprofloxacin. In that study, three matrices were analyzed, with gut collected for 16S rRNA metabarcoding, blood plasma for non-targeted metabolomics, and brain tissue for mRNA-seq analysis. ERY was relatively quickly depurated from fish and gut microbiome dysbiosis was observed at 7 d after exposure, with a slight recovery after the 7-d depuration period. A greater number of plasma metabolites was dysregulated at 14 d compared to 7 d revealing distinct temporal dynamics compared to gut microbiome dysbiosis. Furthermore, several transformation products of antibiotics and biomarker metabolites were observed in plasma due to antibiotic exposure. The transcriptome of the brain was only slightly altered due to antibiotic exposure. Results of these studies will help inform aquaculture practitioners and risk assessors when assessing the potential impacts of antibiotics present in fish feed and the environment, with implications for host health.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"377 ","pages":"Article 144263"},"PeriodicalIF":8.1,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 aims to determine natural TEs concentrations and establish QRVs for selected elements.

The clams showed an important level of essential elements, including Fe and Zn. The concentration of potentially toxic elements, being very low (Hg, Pd and Cd below the legal limits), does not cause health problems, according to risk assessment. The main potentially toxic element found in all samples is Al.

However, the redox “niche” of both dissolved trivalent and monovalent Tl(III/I) remain under-studied in typical oxic-anoxic interfaces. Here, we hypothesize that the behavior of dissolved Tl is constrained by manganese (Mn), iron (Fe), and sulfur (S) species. Dissolved Tl(III/I) profiles and associated redox species Fe(III/II), Mn(II), and S(VI/II) were quantified spatially (a resolution of 1.8 mm) and temporally (diurnal and seasonal) at the rice rhizosphere and the soil-water interface (SWI). The results showed that hotspots of both dissolved Tl(III) and Tl(I) were identified at the rhizosphere and SWI, with redox niche closely following Mn-reducing conditions and also supporting an oxidation mechanism from Tl(I) to Tl(III). Supporting evidence were that newly formed ferromanganese plaque strongly retained the dissolved Tl, while dissolved Tl(III/I) hotspots coincided with moderate Mn-reducing conditions in both SWI and rhizosphere. Dissolved Tl(III) prevailed at higher ratios of dissolved Fe(III)-to-Fe(II). Additionally, porewater Tl(III/I) and copper (Cu(II)) showed similar behaviors at different temporospatial scales, likely due to shared redox constraints. Collectively, the evidence suggests that Mn oxides serve as both sources and sinks of dissolved Tl(III/I) at redox fluctuated areas. Tl mobility was greatly constrained in both more reduced (Fe and S) and more oxidized conditions, highlighting implications for developing effective remediation strategies.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"377 ","pages":"Article 144331"},"PeriodicalIF":8.1,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143674981","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}

The results of the present investigation revealed that MP abundance was higher during the monsoon (45 %), suggesting seasonal runoff and increased plastic pollution during heavy rains as key contributors. We observed microplastics in <em>Liza tade</em> (mullet), with 13.33 MPs/individuals in the summer, 0.77 MPs/individuals in the pre-monsoon, 6.3 MPs/individuals in the monsoon, and 2.67 MPs/individuals in the post-monsoon.
