This study analyzes the impact of extreme weather events on rural insurance contracting in Brazil, using daily precipitation and temperature data to calculate extreme weather indices and perform panel regressions. The analysis of Minimum Comparable Areas (MCAs) between 2006 and 2016 showed that events such as “Frost” and “Hot Days” significantly increased insurance contracting, especially in the South and Central-West regions. The results highlight the importance of extreme variables and the need to consider regional differences and insurance alternatives. Despite the importance of insurance, increasing financial unviability suggests the need for additional strategies, such as crop diversification, community solidarity, and conservation of agricultural practices.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":null,"pages":null},"PeriodicalIF":8.6,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422848","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}

Despite its importance, the end products formed and its mineral transformation pathways, including intermediate steps and underlying mechanisms under Fe(<small>II</small>)<small>_(aq)</small> catalysis still need to be clarified due to decades of dispersed research. In this work, we investigated LP's catalytic transformation with 10 mM and 0.2 mM Fe(<small>II</small>)<small>_(aq)</small> at their natural solution pH's <em>via</em> bulk (X-ray Diffraction/XRD, Raman and Attenuated Total Reflectance Fourier Transform Infrared/ATR-FTIR) and micro/nano-scale (semi <em>in situ</em> Transmission Electron Microscopy/TEM) analysis. In general, we observed that goethite (GT) and LP were the main end products. However, a series of two major distinct intermediate events that were initiated by a dissolution type of reaction along with an “induction period” (lack of dissolution) on LP occurred. Fascinatingly, two of the intermediate steps along its mineral transformation presented novel types of non-classical mechanisms of crystallization <em>via</em> some type of guided oriented particle attachment. Furthermore, one of these intermediate steps is biomimetic in appearance, similar to what is observed during bacterial particle attachment. However, it uses inorganic nano-wire antennas that have a sensory-like function as observed with bacterial fimbriae and/or flagellum through an electron transparent film (similar to a bio-film matrix). Finally, this work leads us to comprehend the evolution of some well documented crystal morphologies for GT commonly observed in natural and anthropogenic settings.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405012","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}

With the expansion of urban population, the urban landscape broadens, and agriculture becomes more commercialized, the connection between the city and agriculture is gradually strengthened. Consequently, there is an urgent need to explore efficient, environmentally friendly, and sustainable modes of urban agricultural production. Carbon dots (CDs), emerging as a novel fluorescent nanomaterial, exhibit remarkable biocompatibility, nanoscale dimensions, low toxicity, and photoluminescence properties. These characteristics render CDs capable of safely and effectively enhancing photosynthesis efficiency, thus revealing immense application potential in the realm of urban agriculture. This paper delves into the characteristics and functionalities of CDs in various agricultural contexts, including plant photosynthesis, plant transport and storage systems, as well as biosecurity considerations. Furthermore, it explores the applications prospects of CDs in urban agriculture, aiming to provide robust support for the advancement of this vital sector.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405078","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}

However, concerns about their environmental impact necessitate a comprehensive assessment of their safety. This study investigated the potential toxic effects of iron-based nanoparticles (NPs) on freshwater planarian and the influence of abiotic factors such as humic acid (HA) and UV exposure on their toxicity. Three different types of iron-based NPs were tested, including commercially available Sigma iron oxide magnetic NPs (Sig_IOMNPs), biologically synthesized BS_IOMNPs and Zn-Fe and bulk FeSO4. Sigma and biogenic nanoparticles had predominantly magnetite (Fe3O4) structure whereas Zn-Fe possessed a bimetallic conformation. Interaction of these NPs with abiotic factors (HA and UV light) led to an increase in their hydrodynamic diameter. In contrast to the commercial sources (Sig_IOMNPs and bulk FeSO4), the biologically synthesized NPs did not cause any acute or sublethal toxicity to the planarian when alone or in combination with HA and UV. These results suggest that biologically synthesized iron-based NPs (Zn-Fe and BS_IOMNPs) may be a safe alternative to conventional bulk iron-based fertilizers. This study highlights the importance of investigating the physicochemical changes of NPs in environmentally realistic conditions and assessing their potential toxicity to aquatic organisms. These findings can contribute to the development of safe and sustainable agricultural practices, promoting the use of iron-based NPs as a new generation of fertilizers.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405015","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}

Despite the extensive research on the cytotoxicities of microplastics, gaps remain in understanding cellular responses to the interplay between environmental weathering and physiological processes. This study aims to fill this knowledge gap by evaluating and comparing the in vitro cellular responses to pristine polystyrene particles, particles weathered under UV light in DI water and seawater, and particles with subsequent incubation in simulated gastric fluid (SGF). In this study, Fourier transform infrared spectroscopy in attenuated total reflection mode (ATR-FTIR), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) were implemented to conduct surface chemistry and morphology characterizations of the particles. The combination of these techniques allowed a comprehensive understanding of surface morphology and chemistry alterations due to the weathering degradation and SGF incubation. Results showed nitrogen and carbonyl groups formed on weathered particles, and seawater-weathered particles showed a more pronounced weathering degree. After SGF incubation, stronger nitrogen and amide groups were detected on the surface of weathered particles, and more organic matter was attached. Two cell lines that are widely used for the evaluation of microplastic cytotoxicity were used, RAW264.7 macrophage and Caco-2 intestine epithelial cells. Results showed weathered and SGF-treated particles enhanced macrophage viability and pro-inflammatory effects compared to pristine particles. Elevated reactive oxygen species (ROS) generation was detected for all particle groups. Weathered particles caused higher cytotoxicity effects on Caco-2 cells and damaged tight junction integrity. The organic matter formation from the SGF incubation protected tight junction integrity and reduced cytotoxicity. These findings highlight the importance of taking both environmental and physiological factors into account for a more comprehensive assessment of microplastic toxicity.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405076","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}

Their short-term and long-term effects on anammox consortia were investigated by batch assays and continuously-fed bioreactors. The addition of 5.0 - 7.4 g L-1 NaCl immediately shielded the acute inhibition of 2.0 - 4.6 mg L-1 CuNPs on anammox activity. However, the coexistence of 5.0 g L-1 NaCl significantly aggravated the inhibitory effect of 3.0 mg L-1 CuNPs on anammox activity after the exposure of about one month through reducing the content of extracellular polysaccharides. Even, the membrane permeability was significantly increased with the further increase of NaCl to 8.0 g L-1. Although the relative abundance of anammox bacteria at the DNA level was relatively higher, most of the anammox cells may not be able to perform metabolic functions normally due to membrane damage. Thus, appropriate salinity would attenuate the adverse impacts caused by the short-term shock of CuNPs, while pre-treatment is required to avoid the synergistic stress of high CuNPs when treating high salt wastewaters.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405016","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}
