As a result, to achieve sustainable development goals, management of MPs/NPs contamination is crucial. Although various studies have evaluated the harmful effects of MPs/NPs, there has been insufficient attention on managing MPs/NPs by nanotechnological interventions. This review first covers the key aspects of advanced strategies, including adsorption, membrane filtration, photocatalytic degradation, magnetic separation, and electrochemistry-driven ways for efficiently sequestering/degrading MPs/NPs from the aquatic environment. An in-depth discussion on the aforementioned strategies along with various nanomaterials/nanocomposites (e.g. micromotors, microswimmers, MOFs, GO, CNTs, etc.), for the mitigation of MPs/NPs is studied. The outlook section offers insights into the conversion of MPs/NPs into valuable products by using nano interventions. Additionally, a brief overview of the economic aspects/ cost analysis of MPs/NPs management, future directions, and prospects is comprehensively documented as futuristic approach.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142541325","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}

Groundwater samples were collected from various locations within Quaid-e-Awam University of Engineering, Science and Technology (QUEST) and Nawabshah city. The objective of this research is to optimize the use of neem seed powder for removal of TDS, hardness, calcium, and magnesium concentration and physicochemical parameters from groundwater samples. Different dosages (0.5, 1.0 1.5, 2.0, 2.5, 5.0, and 10.0 g) and retention speed (0, 50, 100, 125, 150, 175, 200) were tested to optimize the treatment process. At a neem seed powder dosage of 2.0 g, a notable reduction in TDS was observed, with values of 48% for S1, 45% for S2, 52% for S3, and 58% for S4, respectively. Additionally, under a retention speed of 150 rpm, a significant decrease in TDS concentrations was recorded, with reductions of 72%, 65%, 79%, and 62% for S1, S2, S3, and S4, respectively. These results underscore the adsorbent's efficiency. Characterization techniques such as FESEM and FTIR were employed to understand the adsorption mechanism. The neem seed powder exhibited a considerable surface area of 55.30 m²/g according to BET analysis. Kinetic adsorption analysis showed a good fit with the pseudo-second-order (PSO) model with R² values 0.9978, 0.9946, 0.9967, and 0.9954 for TDS, Hardness, Calcium, and Magnesium. A higher R-squared value indicates that the PSO model aligns more closely with the data compared to the pseudo-first-order (PFO) model. The adsorbent molecules undergo a chemical reaction between surface molecules and adsorbate. This indicates chemisorption of adsorbs molecule. The study concludes that neem seed powder is a viable option for TDS removal due to its cost-effectiveness and availability compared to other materials like sodium zeolite and kaolin. Future research could explore the applicability of neem seed powder for removing other contaminants in groundwater or provides valuable insights into utilizing agricultural waste for groundwater treatment, offering a sustainable solution to water quality challenges.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Trees comprise a complex set of microhabitats due to their large biomass and heterogeneity of the architectural components of their trunk surface and branches. Spider species that live on trunks have diversified physiological or morphological adaptations that confer advantages in this environment. In this study, we experimentally examined the habitat choice by the tree-dwelling spiders <i>Selenops cocheleti</i> (Selenopidae), <i>Corinna rubripes</i> (Corinnidae), and <i>Loxosceles gaucho</i> (Sicariidae). We found that microhabitat specialization was restricted to trunk architectural characteristics rather than plant taxonomy. <i>Selenops cocheleti</i> and <i>C. rubripes</i> significantly preferred loose barks and holes in the trunks, respectively, showing that both spider species can evaluate the physical structure of the microhabitat on a fine scale. On the other hand, <i>L. gaucho</i> selected crevices and holes near the base of the trunk without giving much importance to the physical characteristics of the microhabitat per se (e.g., depth, height, length).

Most of these materials will be sourced from the Global South, where the negative ecological and social impacts will be felt. Empirically we explore how this tension is reflected in the European Green Deal, the most comprehensive of the green deal initiatives to date. Analyzing 195 policy documents from the European Union, we find that the role played by the European Green Deal in driving negative impacts beyond its borders is effectively silenced in official discourse. This enables the propagation of a narrative that justifies the dominant paradigm of green growth by portraying the European Green Deal as undertaking a globally ‘just transition’ that ‘do no harm’ and ‘leaves no one behind’. However, it also results in discursive contradictions and inconsistencies that undermine the logic and legitimacy of the European Green Deal. These contradictions and inconsistencies, we argue, provide a possible entry point for efforts to improve the just and inclusive outcomes from the European Green Deal.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":null,"pages":null},"PeriodicalIF":8.6,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

A comprehensive array of characterization methods was employed to probe the photophysical properties of the optimized composite (TO/15-MAB).

The BP neural network model showed that As, Cu, Zn, and Cd concentrations exceeded the risk screening values set by the Soil Environmental Quality Risk Control Standard for Agricultural Land (GB15618-2018), with significant enrichment of As and Cd. Pb showed slight contamination. Spatial analysis indicated that contamination was most severe near the mine and decreased with distance and depth. Grey prediction results suggested that As and Cu levels in the mine restoration area would decline over the next three years, with Cu potentially falling below risk levels by 2024.
