In this study, we designed and synthesized a novel fluorescent Zr-based MOFs, denoted as MOF-808-NH₂, through the post-synthetic modification of 2-amino terephthalic acid (BDC-NH₂) on coordinatively unsaturated Zr sites, thereby preserving the structural stability of the parent framework. The MOFs exhibited exceptional turn-on fluorescence in aqueous solutions containing fluoride ions (F⁻). The interaction between the-NH₂ groups on MOF-808-NH₂ and F⁻ facilitated the formation of hydrogen bonds, significantly enhancing the fluorescence emission intensity of BDC-NH₂ at 450 nm and inducing a blue shift in the fluorescence emission peak, enabling the specific recognition of F⁻ even in the presence of various anionic interferences. Notably, MOF-808-NH₂ demonstrates an ultrafast response time (within 30 s), a high detection sensitivity with a limit of detection of 1.56 μM, and remarkable selectivity and anti-interference properties with pronounced fluorescence emission against a dark background. Furthermore, MOF-808-NH₂ retained outstanding thermal, mechanical, and chemical stabilities, underscoring its potential for practical applications in selective F⁻ detection.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"276 ","pages":"Article 121469"},"PeriodicalIF":7.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143727174","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}

Here, we employed the environmental DNA (eDNA) records of the sediment core profiles to explore the effects of the dam construction on algal and fish community structure and biodiversity in the Three Gorges Reservoir in China for the past few decades. We detected 242 genera of algae and 62 species of fish in the sediment cores of the Xiangxi River estuary, the main tributary of the reservoir. The structure of algal and fish communities was changed significantly before and after damming. The dominant species in the algal community shifted from <em>Cyanophyta</em> to <em>Bacillariophyta</em>, while the dominant species in the fish community remained <em>Cypriniformes</em>, and the species diversity fluctuated greatly after damming. In addition, the Non-metric Multidimensional Scaling (NMDS) analysis showed that the composition of algal communities differed significantly among different sequences, while the differences among fish community groups were relatively small. The total nitrogen (TN) and total phosphorus (TP) in sediments were expected to be the main factors, affecting the abundance of eDNA in algae and fish in sediments.

In this work, the role of iron minerals in visible light-activated persulfate for BDE-47 degradation was systematically investigated. Under visible light irradiation, low-dose persulfate (PS) (10 μM) is capable of achieving the rapid elimination of BDE-47 in the presence of iron minerals, and goethite exhibited the best performance among selected iron minerals. In Goe/PS/vis system, the reactive species involved in the degradation of BDE-47 included ·OH, SO₄·^-, O₂·^-, h⁺ (photo-generated hole), and e⁻. The existence of O₂ and S₂O₈²⁻ led to the synergy of ROS generation derived from h⁺/e⁻. Four oxidized intermediates of BDE-47 with lower estimated toxicity were identified by high-resolution mass spectrometry (HRMS), suggesting that PS-based in-situ remediation driven by goethite and visible light can achieve deep mineralization and detoxification of BDE-47. In addition, the Goe/PS/vis system adapts to various co-existing anions and NOMs. Co-existing heavy metals facilitated BDE-47 removal. Heavy metal ions adsorbed on goethite are reduced to zero valent metal by photoelectron during irradiation, which further promotes electron transfer. While heavy metals entering the goethite lattice in the form of isomorphous substitution introduce oxygen vacancy, further promoting BDE-47 degradation. These findings reveal the critical role of natural iron minerals in PS-based in-situ remediation for polluted water and soils under solar irradiation and provide new ideas for developing efficient strategies for the combined contamination of PBDEs and heavy metals.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"276 ","pages":"Article 121477"},"PeriodicalIF":7.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705101","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}

Microalgae biodiesel with boron oxide (B₂O₃) NPs has not been evaluated for diesel engine performance. The study introduced B₂O₃ NPs to biodiesel produced from transesterification of 3rd-generation spirulina microalgae oil (SMO) under 500, 1000, 1500, 2000, 2500, and 3000 W engine loads.

The nature of the early (primary) oxidation species depends on whether the deactivation took place under humid or dry, aerobic or anaerobic conditions. The current theoretical investigation provides new insights into the reaction mechanisms for such degradation products, specifically imine, aldehyde and CO₂, depending on the radical species involved, and the deactivation conditions. A common radical to all reactions referred to as αC^•, corresponds to the abstraction of a hydrogen atom from the α-position with respect to an amine group. In dry anaerobic environment, imine formation involving organic radicals R^• generated thermally, has an activation barrier of 13.54 kcal mol⁻¹. In humid anaerobic environment, the imine formation in the presence of hydroxyl radicals (HO^•) corresponded to much lower activation barriers than organic radicals. However, the generation of HO^• radicals would be difficult in the absence of oxygen. Hydroperoxyl radicals (HOO^•) occur only in the presence of oxygen, but their formation is facilitated in the presence of humidity. Oxidation of amine to aldehyde occurs in two stages, involving oxygen atom implantation on α-carbon, then the formation of aldehyde and ammonia. In dry aerobic conditions, oxygen implantation involving HOO^• has a high activation energy of 19.60 kcal mol⁻¹, while the subsequent reaction into aldehyde has a very low barrier of 2.38 kcal mol⁻¹. In contrast, in humid anaerobic environment, both steps occur in the presence of HO^• radicals, with a much lower activation barrier for the first step than the latter (1.52 vs. 22.34 kcal mol⁻¹).
