The conventional sulfate removal process using chemical precipitation consumes much energy and results in the production of additional pollutants that decrease its scalability and treatment performance. Microbial electrolysis cells (MECs) using sulfate-reducing bacteria (SRB) is a promising sustainable technology for treating wastewater and recovering resources because the metabolic process of SRB in MECs can convert sulfate to sulfide while the cells also produce bioenergy through electrochemical processes. This review focuses on the processes of sulfate reduction in MECs that have demonstrated potential for sulfate removal and hydrogen production and heavy metal elimination and organic pollutant degradation. This review also systematically discussed machine learning systems that optimize MECs performance and result prediction and efficiency enhancement. The SRB-MECs systems have two advantages by producing clean energy while treating wastewater that makes them suitable for application in industrial processes. The two main challenges for the implementation of these systems are the scalability of the system and its long-term operational reliability. This review highlights the need for more research to enhance system performance and microbial efficiency and accelerate the practical implementation of SRB-MECs technology as a sustainable and energy-efficient solution for treating industrial effluents.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"121857"},"PeriodicalIF":7.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144085534","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}

Hollow mesoporous carbon spheres (HMCS) possess tunable hollow mesoporous structures, serving as both an excellent adsorbent and catalyst. However, its adsorptive function in catalytic degradation processes has been easily ignored. This work highlights the remarkable adsorption capacity of CoFe₂O₄@HMCS (q_e = 404.32 mg g⁻¹). During the synergistic process of adsorption and degradation, LFX can be rapidly and efficiently enriched by CoFe₂O₄@HMCS, achieving 93.42 % removal within 60 min through subsequent synergistic degradation. The HMCS can stabilize CoFe₂O₄ under complex reaction conditions, reducing Co/Fe leaching. Simultaneously, the combination of HMCS and CoFe₂O₄ also endows HMCS with magnetic properties, which further enhances the catalytic performance of the composite material. Furthermore, a dual-pathway mechanism for PMS activation was proposed, demonstrating that both radical (SO₄^−• and •OH) and nonradical (direct electron transfer) pathways cooperatively contributed to LFX degradation through PMS activation, with the direct electron transfer mechanism playing a dominant role. Meanwhile, the potential transformation pathways of LFX were elucidated. This research aims to develop a magnetically recoverable catalyst with strong adsorption and catalytic capabilities for more practical water treatment applications.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"279 ","pages":"Article 121858"},"PeriodicalIF":7.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144072195","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}

Surface water, groundwater, and sediment samples were collected from selected micro-watersheds, primarily used for forest plantation, and PFOS and its precursors were assessed by ultra-performance liquid chromatography coupled to a triple quadrupole tandem mass spectrometer. PFOS was the most frequently detected compound, present in 76% of surface water samples, with concentrations up to 50.6 ng L^-1. EtFOSA and perfluorooctane sulfonamide (FOSA) were also detected but at lower frequencies and concentrations. The highest PFOS concentrations were found in the watershed with mixed urban/industrial and agricultural activities, indicating multiple contamination sources. However, groundwater samples from monitoring wells inside planted forests of Pine and Eucalyptus also showed detectable PFOS contamination, likely due to the biodegradation of EtFOSA from ant bait applications. Sediment samples revealed seasonal variations, with higher detection rates during the dry season, suggesting a high-mobility of the studied compounds. Risk assessment using the risk quotient (RQ) approach indicated that all measured PFOS concentrations exceeded the European Union's annual average environmental quality standard (AA-EQS) for inland surface waters, posing potential risks to aquatic biota.

This review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, and the methodological quality of the studies was evaluated using the Risk of Bias Rating Tool for Human and Animal Studies developed by the National Toxicology Program's Office of Health Assessment and Translation (OHAT). Publication bias was assessed using the caliper test. Fifty-four eligible studies were identified. Despite poor ratings in certain aspects of the risk of bias evaluation, the quality of the studies was generally relatively good, with only four studies receiving the weakest rating. Overall, there was very little evidence that ELF MFs alone are carcinogenic. Evidence of co-carcinogenicity, from studies that have used ELF MFs in combination with other agents, remains inconclusive. A clear indication of publication bias was observed, though it is unlikely that this bias alone explains all reported MF-modified effects.

However, MOFs particles in powder form are prone to agglomeration and adhesion effects in water, which leads to problems such as difficult separation and secondary pollution. As an ideal carrier for MOFs, aerogels exhibit a unique three-dimensional interconnected pore structure, which endows aerogels with high porosity properties and excellent adsorption capacity. Researchers have skillfully combined MOFs with aerogels to create a new type of MOF aerogel composites (MOFACs). These composites are converted into highly porous and high-strength carbon aerogels through a high-temperature pyrolysis process in an inert environment. These carbon aerogels not only retain the high catalytic efficiency of MOFs, but also inherit the advantages of aerogels in terms of light weight, low density and easy handling.

In this study, the life-history parameters, transcriptomic regulation, multi-generational offspring size, and population dynamics of rotifers were determined in response to BTBPE (0, 0.01, 1, and 100 μg/L). The results showed that BTBPE (&gt;1 μg/L) significantly increased the pre-reproductive time, shortened both reproduction periods and the lifespan, and decreased the total number of rotifer offspring. Transcriptomic analysis revealed that the expression of key genes involved in the pathways of citrate cycle, 2-oxocarboxylic acid metabolism, carbon metabolism, and propanoate metabolism was affected. Moreover, BTBPE has transgenerational effects on rotifers, the size of the F1 to F5 generations decreased significantly in response to BTBPE. Finally, the population density in the 100 μg/L BTBPE treatment group was significantly reduced by 30 % compared to the control group, suggesting that the population growth of rotifers was inhibited by BTBPE exposure. The findings of this study indicate that BTBPE has effects on the individual reproduction, population growth, offspring quality, and energy metabolism of rotifers.
