The sludge lysis was conducted by ultravio-sonication (UVS). The effects of wavelength and power of ultraviolet (UV), and sludge concentration and alkali treatment were investigated. The results found that the power of the UV impacted the sludge lysis degree (DD_COD) more strongly than the wavelength, which could increase the amount of TP, PO₄³⁻-P, TN, NH₄⁺-N, protein and polysaccharides in the supernatant but reduce the percentage of carbon, nitrogen and phosphorus. During the lysis by UV-ultrasound, DD_COD increased slightly as the sludge concentration increased, and alkali treatment was more conducive to the dissolution of substances. Under the conditions of ultrasonic power 400 W and frequency 40 kHz, UV power 16 W and wavelength 185 nm, sludge concentration 12,000 mg·L⁻¹, pH = 11 (alkali treatment), the contents of TP, PO₄³⁻-P, TN, NH₄⁺-N were 297.1 mg·L⁻¹, 183.9 mg·L⁻¹, 522.3 mg·L⁻¹, and 58.9 mg·L⁻¹, respectively, with DD_COD reaching up to 63.02%.

The autocatalytic interaction between hematite and Fe(II)-oxalate has long been of interest for its environmental and industrial relevance. In this study we take advantage of iron isotopic labelling and mass-sensitive imaging at the single particle scale to determine how changes in solution composition correlate with the morphologic evolution of faceted, micrometer-sized hematite platelets. Net dissolution is confirmed through analyses of aqueous iron chemistry, as well as by quantitative atomic force microscopy. Isotopic mapping techniques show that Fe(II) readily adsorbs to (001) and (012) surfaces in the absence of oxalate, but when oxalate is present selective dissolution of the (001) surface prevails and 57Fe deposition via recrystallization is not observed. Comparison between particle microtopographies following reaction with Fe(II), oxalate, and Fe(II)-oxalate show substantially different behavior, consistent with distinct mechanisms of interaction with hematite surfaces. The extensive characterization conducted on the coupled solution/solid dynamics in this system provides new insight for distinguishing crystal growth, dissolution, and recrystallization processes.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"18 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026770","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}

Increasing of biodegradation because of higher biochar is mainly related to improvement of circumstance for higher microbial activity, while inhibition effects of iron nanoparticles on decreasing microbial activities in 10 g kg⁻¹ is related to toxicity of nanoparticles on microbes.

The goal of this multifaceted analysis is to provide an up-to-date picture of MPs in the aquatic system with an emphasis on the marine environment. As of now, the growing concern of MP is due to high level fragmentation. The high surface area to volume ratio, crystallinity, and functional groups of MPs allows them to interact with a broad assortment of pollutants, including heavy metals, antibiotics, and persistent organic compounds. Understanding the origin, source, and fate of MPs in the marine environment is challenging, however, crucial for better management and regulation of MPs. Various spectroscopic and microscopic techniques can be applied to analyze MPs. This review article demonstrates the concept of MP lifecycle and footprint covering transport mechanism and pathways, possible characterization, degradation, and remediation processes.

This study investigated the field performance of a downpipe treatment system (DPTS) using waste seashells to remove aluminium, zinc, and copper from roof runoff. First-flush runoff samples were collected before and after treatment during 30 events over 18 months. Results showed that Zn (85–97%) and Cu (59%) in runoff were predominantly dissolved, while Al (71–90%) was mainly particulate. Metal concentrations were largely influenced by the roof material, and weak correlations were observed with climate characteristics. The DPTS effectively removed particulate metals from copper (76 ± 48% Cu, 80 ± 41% Al) and galvanised (75 ± 49% Zn, 74 ± 27% Al) roof runoff. It also removed dissolved metals from Zincalume® (53 ± 32% Zn, 60 ± 30% Al) and Aluminium (96 ± 5% Zn) roof runoff, sustaining performance over 542 days of operation. Metal removal was linked to initial concentrations, partitioning, and metal affinity for the filter media, with precipitation, where metals formed insoluble compounds, and adsorption, where metals bound to the surface of the shells, as potential mechanisms. This study demonstrates that repurposing waste seashells in roof runoff treatment offers a low-cost, scalable and easily retrofittable solution for treating heavy metal pollution at its source, directly supporting Sustainable Development Goals (SDG), particularly Clean Water and Sanitation (SDG 6), Responsible Consumption and Production (SDG 12), and Sustainable Cities and Communities (SDG 11).</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 2","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-025-07766-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

We ask: if they knew, why were they not prepared? Through a review of strategic planning documents and a qualitative analysis of semi-structured, key actor interviews, we analyze the impact of adaptive capacity on adaptation implementation. Our findings demonstrate that institutional barriers limited adaptive capacity, stagnated adaptation implementation and, in consequence, existing infrastructure and emergency management were insufficient to prevent acute impacts during the event. Further discussion identified formal and informal institutions preventing adaptation implementation: Formally, hierarchical governance decreased community adaptive capacity and led to infrastructure deficit, while informally, development-driven decision-making overshadowed infrastructure mitigation and preparedness priorities. Historical anthropocentric decisions persisted through path dependencies, preventing resilient decision-making during a time of rapid change. Recommendations are made to address these barriers and empower communities to prepare for climate change.

In this context, road traffic is a significant factor in the contamination of the urban environment in general, and runoff in particular.

The present study focuses on characterizing the number concentration and mass distribution of nanoparticles (NPs) containing Ti, Fe, Zn, and Cu in runoff from a heavily trafficked urban motorway (≈ 100,000 vehicles/day) in Nantes, western France. Seven runoff samples were taken between July 2023 and March 2024. A rainfall sample was also taken in the same proximity for comparative purposes, providing knowledge of atmospheric wet deposition levels. Using two sample preparation methods, filtration, and ultra-filtration, single particle ICP-MS (sp-ICP-MS) analysis confirmed the existence of the targeted elements in nanoparticulate fraction. Ti was found to be the most abundant element, followed by Fe, while Zn and Cu were less prevalent, with average number concentrations of 4.83 x 10^8, 1.68 x 10^8, 7.78 x 10^7 and 9.04 x 10^7 particles/L, respectively. Except for Fe, runoff samples exhibited higher concentrations of Ti, Zn, and Cu nanoparticles compared to the rainfall sample, with a larger average equivalent diameter indicating a likely anthropogenic origin.
