Zebrafish (<em>Danio rerio</em>), a key vertebrate model, have demonstrated a range of neurobehavioral effects following MP/NP exposure, including altered locomotion, anxiety-like responses, disrupted circadian activity, and impaired social interaction. Neurotoxicity appears to be strongly size-dependent: NPs, capable of crossing the blood–brain barrier, induce direct neuronal damage primarily <em>via</em> oxidative stress and neurotransmitter imbalance, whereas larger particles exert indirect effects through systemic inflammation and gut–brain axis perturbation. Key neurochemical alterations, such as changes in acetylcholinesterase, dopamine, gamma-aminobutyric acid, and serotonin, are consistently associated with behavioral phenotypes. These outcomes are further modulated by exposure concentration, particle chemistry, and interactions with environmental co-contaminants. While mechanistic insights are expanding, most studies rely on simplified laboratory conditions that lack environmental realism and cross-species relevance. To advance ecological risk assessment, future research must adopt integrated, multi-level approaches that reflect real-world exposure scenarios and link mechanistic pathways to functional neurobehavioral outcomes.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"82 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144906213","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}

Those within industrial clusters seeking better treatment of workers, vulnerable and marginalized groups, and the environment demand that action to combat the climate crisis contribute to “just transitions.” Yet what constitutes a just transition is subjective, involving competing claims and tensions between key advocates about what has been (un)just and what is required to advance more fair and equitable outcomes. This study brings into view the perspectives of those not typically at the decision-making table. We build from previous projects collecting the “lived experiences” that aim to lift-up diverse voices from local communities. Our approach uses original semi-structured interviews (N = 24), focus groups (six with N = 45 total participants), participant observation in England, Scotland and Wales coupled with local surveys in three clusters (n = 600) and nationally representative survey data (N = 1,178 respondents), all of which were conducted from June 2022 – November 2024. We identify five themes arising from these data: place-based perceptions and local identities, potent lived experiences of injustice, technology-specific concerns, issues of trust and awareness, and issues concerning policy and governance. We then discuss these five themes considering recent literature on recognition justice and sense of place, procedural justice and community engagement, and distributive justice and localising benefits. The resulting evidence provides insight as to how net-zero industrial transitions are perceived by local communities, and data from the national survey allows us to show how local perspectives align and resonate with UK publics on a national scale.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103051"},"PeriodicalIF":9.1,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 synthesized PbFe12O19-NPs were characterized by spectroscopic techniques and employed to develop an electrochemical sensor (PbFe12O19-NPs/GCE). The PbFe12O19-NPs/GCE-based electrochemical characterization was accomplished by cyclic voltammetry (CV).

This study integrated random forest techniques and 264,302 daily bank transaction data from 271 Chinese cities (2017–2019) to simulate household medical expenditure responses to climate change. To observe the heterogeneity among different cities, cities are categorized into 14 city groups based on their historical temperature and economic conditions to build simulation models. We further projected the future household medical expenditures in different cities under four Shared Socio-economic Pathways (SSPs), considering the pure effects of climate change and sensitivity changes under SSP-informed socioeconomic and physiological scenarios. We find that households in higher-income cities and cities with historically low temperatures have enhanced resilience to heat and cold, respectively. Climate change is projected to slightly decrease household medical expenses in China by 5.2% (SSP126) to 5.6% (SSP585) in 2060, attributed to fewer cold-related medical expenditures. Under the physiological scenarios, enhanced body system functions are projected to reduce medical expenditures by 19.5% (SSP245) to 27.6% (SSP585) by 2060. Rising incomes under socioeconomic scenarios may stimulate healthcare demand and drive expenditures up by 4.9% (SSP370) to 22.5% (SSP585).

Samples from natural populations were collected from diverse ecological zones of the Cholistan Desert exhibiting varying levels of drought intensity and resource availability. In the present study, structural and functional modifications in three <i>Tribulus</i> species under desert stress conditions were evaluated. It was hypothesized that each species would exhibit species-specific morphological, physiological, and anatomical adjustments to optimize survival under desert stress. All three species responded distinctly under different environmental conditions. The most notable feature in <i>T. longipetalus</i> under drier habitats was enhanced accumulation of total soluble proteins, sugars, amino acids, and thicker dermal and vascular tissues supporting stress endurance. <i>T. terrestris</i> exhibited better performance in highly stressful zones, showing increased shoot biomass, soluble osmolytes, and maximum chlorophyll content. <i>T. pentandrus</i> showed vigorous growth in less stressful habitats with highest pigment content and shoot biomass, whereas populations from dry sites displayed increased metaxylem and vascular bundle size. Structural and functional traits such as well-developed vascular bundles, Kranz-type leaf anatomy with thickened mesophyll and bundle sheath cells, and increased epidermal and sclerenchymatous tissues contributed to water retention, transport efficiency, and mechanical support. Significant variability in stomatal traits among species reflected adaptive strategies for gas exchange and water conservation.
