Increasing evidence suggests that early-life environmental exposures can induce persistent alterations in adipose tissue, contributing to long-term metabolic dysfunction. Manganese (Mn) is an essential trace element involved in mitochondrial function, redox homeostasis, and energy metabolism; however, both Mn deficiency and overexposure have been associated with adverse metabolic outcomes. Despite epidemiological studies linking Mn exposure to obesity-related disorders, the cellular mechanisms underlying Mn-mediated metabolic disruption remain poorly understood. Here, we investigated whether transient Mn exposure during the early adipogenesis induces persistent molecular and metabolic alterations in mature adipocytes. Using the 3T3-L1 cell line, pre-adipocytes were exposed to increasing Mn concentrations (0, 5, 10, 50, 100, or 500 μM) during the first 48h of differentiation (confluence phase). Mn was subsequently removed, and cells were either maintained as non-differentiated controls or differentiated using a defined 3T3-L1 protocol designed to generate adipocytes with white morphology and beige-like features. Upon maturation, adipogenic markers, lipid accumulation, β-adrenergic-induced lipolysis, glucose transporter gene expression, and antioxidant defense-related protein and gene expression were assessed. Early Mn exposure elicited persistent concentration-dependent alterations in adipogenic programming, characterized by reduced lipid accumulation and sustained suppression of the adipogenic regulators PPARγ and C/EBPα. Fully differentiated adipocytes also exhibited persistently impaired expression of glucose transporter genes and reduced hormone-sensitive lipase activation, leading to diminished lipid mobilization under β-adrenergic stimulation. Combined, these findings demonstrate that transient Mn exposure during the initial stages of adipocyte differentiation is sufficient to cause long-term alteration of adipogenic programming and provides evidence for a mechanism of persistent metabolic disruption. Importantly, lower Mn concentrations were associated with selected persistent alterations in adipocyte maturation, whereas the strongest effects observed at 500 μM Mn likely included cellular stress or toxicity-associated responses.</p>","PeriodicalId":73763,"journal":{"name":"Journal of hazardous materials advances","volume":"23 ","pages":"101506"},"PeriodicalIF":9.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13593052/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149019046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review comprehensively examines the recent advances in MOF-based materials for the removal of BPA through adsorption and photocatalytic degradation.

The effects of key operational parameters—such as pH, temperature, adsorbent/photocatalyst dosage, and coexisting ions—on removal performance are critically analyzed. Furthermore, adsorption isotherms, kinetics, thermodynamics, and photocatalytic mechanisms are discussed in detail, with emphasis on the roles of π–π interactions, hydrogen bonding, hydrophobic effects, and reactive oxygen species generation.

This review critically synthesizes advances in BC–HG research by linking substrate choice, synthesis techniques, and physicochemical characterization with performance outcomes across environmental and agricultural applications. This review further highlights how synthesis-driven composite architecture governs dominant adsorption pathways, enabling design-oriented optimization beyond model-based interpretation. Mechanistic insights from adsorption kinetics, isotherm modeling, and thermodynamics are integrated to explain the composites’ ability to remove heavy metals, dyes, pharmaceuticals, and emerging contaminants, while simultaneously supporting nutrient recovery, soil fertility, drought resilience, and greenhouse gas reduction. Compared to standalone biochar or hydrogels, BC–HGs exhibit enhanced mechanical stability, swelling behavior, and pollutant affinity, positioning them as multifunctional platforms for remediation and sustainable resource use. However, challenges remain in scaling up synthesis, improving regeneration efficiency, ensuring stability under real-matrix conditions with competing ions and natural organic matter, and addressing risks from waste-derived feedstocks.

We systematically summarized the methods, effects and mechanisms of CMs and modified clay minerals (MCMs) on the immobilization of typical HMs in soil. Studies have shown that raw clay minerals can effectively immobilize heavy metal cations, while modification treatments that increase their specific surface area, number of functional groups, and heavy metal precipitant content can significantly improve the immobilization efficiency.

{"title":"Towards a fingerprint of aqueous film-forming foam (AFFF) as source of PFAS across environmental compartments","authors":"Nikola Krlovic,&nbsp;Heidemarie Paula Schaar,&nbsp;Jörg Krampe,&nbsp;Matthias Zessner,&nbsp;Ottavia Zoboli","doi":"10.1016/j.hazadv.2026.101196","DOIUrl":"10.1016/j.hazadv.2026.101196","url":null,"abstract":"<div><div>The use of Aqueous film-forming foams (AFFF) is a major emission source of per- and polyfluoroalkyl substances (PFAS). This review explores whether fingerprints of AFFF contamination can be identified. We examine the composition of AFFF formulations and whether the physicochemical properties of AFFF-related PFAS differ from those of other PFAS. We then compare the distribution patterns of PFAS in various environmental compartments at AFFF-impacted sites. Either PFOS or 6:2 FTS congeners usually dominate formulations, depending on the production method. PFHxSAm, a potential precursor to FHxSA and PFHxS, was also found to be relevant in AFFFs produced via electrochemical fluorination. The analysis of the chemical descriptors suggests that AFFF-related PFAS are constitutionally similar, regardless of the manufacturing process. On average, PFOS accounts for 75% of the total content of the most detected PFAS in soils, while 6:2 FTS and its congeners were dominant where exclusively telomerisation-based AFFF were applied. PFHxS, PFHxA and PFOA were the next most detected compounds. Groundwater shows a lower median share of PFOS (50%), a higher occurrence of short chain PFCA and PFSA and a larger range of concentrations. These findings rely on surveys primarily targeting a limited number of compounds. In a few cases, FHxSA, its related compounds, and 6:2-FTAB accounted for a large fraction of total analyzed PFAS in affected sites. This review marks a significant step forward in identifying fingerprints of AFFF-PFAS contamination, and it highlights the need to expand the analytical panel in environmental monitoring at AFFF-impacted sites.</div></div>","PeriodicalId":73763,"journal":{"name":"Journal of hazardous materials advances","volume":"22 ","pages":"Article 101196"},"PeriodicalIF":7.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147849875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
