Unraveling the water activation is essential in the catalytic hydrolysis of organic sulfur compounds, yet its intrinsic mechanism of the water-promoting effect is still unclear. In this work, we describe novel findings of oxygen vacancy (VO) engineering by facile regulating CeO2 nanocatalysts with different shapes (rod, octahedral, sphere and cube) for COS hydrolysis at lower temperature, aiming at understanding the structural origin of the excellent catalytic hydrolysis activity. Unexpectedly, among CeO2 catalysts with different morphologies, spherical CeO2 (CeO2-S) catalysts can achieve completely conversion of COS at 60 ℃ and maintain 30 hours of non-deactivation, which is a significant improvement in catalytic activity and reaction temperature compared to previously reported catalysts. Through various characterizations and results analysis, it is obvious to see that the more spontaneous formation VO on CeO2-S catalysts synergistically induced the water activation and dissociation thus result in the generation of more surface active hydroxyl groups (-OH), which contributes to the enhanced performance of COS catalytic hydrolysis at lower temperature. The promoting effect of catalyst morphology changes on COS hydrolysis were furthering analyzed using in situ DRIFTS and DFT calculations, and revealed that the exposed (111) crystal plane of CeO2 exhibits the strongest adsorption capacity for COS. Notably, CeO2-S also exhibited good catalytic performance and stability towards to other typical organic sulfur compounds (COS and CS2), which is beneficial for the wide application at complex operating conditions. This study provides new insights for designing OH-rich CeO2 catalysts to remove single as well as multi-component organic sulfur compounds for different applications at lower temperatures.

Direct Air Capture (DAC) technologies are anticipated to achieve megaton-scale by 2030 and gigaton-scale by 2050. However, current capture costs and pace of development cast doubt on DAC's readiness to contribute to the environmental goals in the 2030s. This study introduces an innovative framework to reduce capture costs and facilitate the widespread deployment of DAC technologies. First, an extensive review of the current state of DAC deployment is conducted, followed by an analysis of the DAC market outlook. Secondly, the methodology involves the techno-economic assessment of our case study, the integration of absorption-based DAC systems with the urea manufacturing process (DAC-to-urea). This leads to the formulation of two First-of-a-kind (FOAK) DAC-urea designs based on process intensification. The initial focus is to demonstrate the technical and economic feasibility of the proposed concepts. FOAK costs are projected into the future by outlining distinct deployment scenarios using the learning rates principle. Estimates from the optimistic deployment case indicate that low renewable electricity prices and ambitious learning rates lead to competitive DAC-based urea prices (611-726 $/t urea), while achieving promising capture costs (154-263 $/tCO₂). In that context, renewable ammonia generation acts as the primary bottleneck for sustainable urea production employing air-captured CO₂. This outcome strengthens DAC-CO₂ role as a chemical feedstock for high-demand commodities in future sustainable economies. However, results derived from the delayed deployment scenarios (280-560$/tCO2) align with innovative cost assessment approaches from the literature. Findings highlight the dependency of DAC cost predictions on elevated learning rates and immense increases in capacity.

Underlying surface in lake watersheds and mercury concentrations in lake inflows are key factors affecting the accumulation of mercury in lake sediments. Lake characteristics play a crucial role in the process of mercury methylation in sediments. Lakes in cold regions have unique environmental features, including a long ice-cover period, during which mercury undergoes complex physicochemical processes. However, the extent of mercury accumulation and methylation in cold region lake sediments remains unclear. We studied the concentrations, pollution levels, and ecological risks of mercury and methylmercury in surface sediments from six lakes in China's cold regions, and analyzed the mechanisms by which lake characteristics influence mercury methylation. The results indicate significant mercury enrichment in surface sediments of typical lakes in Inner Mongolia, with some regions exceeding the average mercury levels found in lakes across China. Mercury concentrations in surface sediments of lakes from different land use types within their watersheds show considerable spatial variability, with the following pattern: agricultural irrigation areas > agro-pastoral transition areas > grassland and sand areas. Agricultural activity intensity in lake watersheds has the most pronounced impact on the spatial heterogeneity of surface sediment mercury concentrations and their associated ecological risks. Lake water input and geographical location can indirectly control the spatial distribution of mercury concentrations and ecological risks in Inner Mongolia lakes by affecting external mercury inputs. The methylation process in lake surface sediments during the ice-cover period is significant. Based on a correlation analysis model, water depth was found to be a key factor controlling methylmercury content and mercury methylation rates in lake sediments during the ice-cover period. Deep water lakes promote the conversion of mercury into methylmercury in sediments. Water depth influences the redox conditions of sediments and the amount of light radiation received by the sediments, thereby affecting the methylation and demethylation processes of mercury, ultimately controlling the levels of methylmercury in sediments.

Benzotriazole UV-Stabilizers (BZT-UVs), compounds added to plastics to reduce ultraviolet degradation, are considered contaminants of emerging concern given their environmental persistence and documented toxicity in humans and animals. UV328 is a BZT-UV that has been recently listed to Annex A of the Stockholm Convention; therefore, understanding species exposure is critical information to fulfill international and domestic regulatory obligations. We evaluated hepatic accumulation of 12 plastic additives (including nine BZT-UVs) in Larus gulls in Atlantic Canada. BZT-UV accumulation was assessed in relation to ingested plastics, hepatic heavy metal accumulation, and body condition. Ninety-six percent of gulls had at least one BZT-UV at detectable hepatic concentrations. The most frequently detected BZT-UVs were UVP (91.4%) and UV328 (76%), suggesting ubiquitous exposure across individuals. We demonstrated interspecific differences in the relationship between ingested plastics and accumulated contaminants, with a positive relationship detected between ingested plastics and both UVP and UV328 in American herring gulls (Larus argentatus smithsonianus), and a positive relationship between hepatic UV328 and Pb concentrations detected in great black-backed gulls (Larus marinus). We provide evidence that Larus gulls feeding at a coastal landfill are highly exposed to BZT-UVs, and that the relationship between ingested plastics and plastic-associated contaminants varies across sympatric species.

The relative importance of abiotic and biotic factors in determining species distributions has long been of interest to ecologists but is often difficult to assess due to the lack of spatially and temporally robust occurrence records. Furthermore, locating places where potentially highly competitive species co-occur may be challenging but would provide critical knowledge into the effects of competition on species ranges. We built species distribution models for two closely related species of small mammals (Neotoma) that are largely parapatric along mountainsides throughout the Great Basin Desert, USA using extensive modern occurrence records. We hindcasted these models to the mid-Holocene to compare the response of each species to dramatic climatic change and used paleontological records to validate our models. Model results showed species co-occurrence at mid-elevations along select mountain ranges in this region. We confirmed our model results with fine-scale field surveys in a single mountain range containing one of the most extensive survey datasets across an elevational gradient in the Great Basin. We found close alignment of realized distributions to the respective abiotic species distribution model predictions, despite the presence of the congener, indicating that climate may be more influential than competition in shaping distribution at the scale of a single mountain range. Our models also predict differential species responses to historic climate change, leading to reduced probability of species interactions during warmer and dryer climatic conditions. Our results emphasize the utility of examining species distributions with regard to both abiotic variables and species interactions and at various spatial scales to make inferences about the mechanisms underlying distributional limits.

MotivationPollinators play a crucial role in maintaining Earth's terrestrial biodiversity. However, rapid human‐induced environmental changes are compromising the long‐term persistence of plant‐pollinator interactions. Unfortunately, we lack robust, generalisable data capturing how plant‐pollinator communities are structured across space and time. Here, we present the EuPPollNet (European Plant‐Pollinator Networks) database, a fully open European‐level database containing harmonised taxonomic data on plant‐pollinator interactions referenced in both space and time, along with other ecological variables of interest. In addition, we evaluate the taxonomic and sampling coverage of EuPPollNet, and summarise key structural properties in plant‐pollinator networks. We believe EuPPollNet will stimulate research to address data gaps in plant‐pollinator interactions and guide future efforts in conservation planning.Main Types of Variables IncludedEuPPollNet contains 1,162,109 interactions between plants and pollinators from 1864 distinct networks, which belong to 52 different studies distributed across 23 European countries. Information about sampling methodology, habitat type, biogeographic region and additional taxonomic rank information (i.e. order, family, genus and species) is also provided.Spatial Location and GrainThe database contains 1214 different sampling locations from 13 different natural and anthropogenic habitats that fall in 7 different biogeographic regions. All records are geo‐referenced and presented in the World Geodetic System 1984 (WGS84).Time Period and GrainSpecies interaction data was collected between 2004 and 2021.Major Taxa and Level of MeasurementThe database contains interaction data at the species level for 94% of the records, including a total of 1411 plant and 2223 pollinator species. The database includes data on 6% of the European species of flowering plants, 34% of bees, 26% of butterflies and 33% of syrphid species at the European level.Software FormatThe database was built with R and is stored in ‘.rds’ and ‘.csv’ formats.

Microplastics, as a prominent emerging pollutant in marine environments, pose a serious threat to the stability of marine ecosystems due to their resistance to biodegradation. MPs act as substrates for biofouling and potentially promote the spread of harmful microorganisms. Research indicates that human activities exacerbate MPs pollution in aquaculture environments, significantly increasing their abundance. This study focused on the aquaculture environment of the large yellow croaker (Larimichthys crocea), one of the most extensively farmed fish species in coastal regions. We conducted a comprehensive analysis of microbial diversity on the biofilms covering MPs and in the surrounding aquaculture water, with a focus on the distribution of pathogens on MPs. Furthermore, this study investigated the impact of seasonal variations on the microbial communities within these biofilms. Sequencing analysis revealed that the α-diversity of microbial communities on MPs was lower than that in aquaculture water during winter but higher in summer, indicating a seasonal shift in microbial community structure. PICRUSt predictions suggested that microbes on MPs possess unique metabolic pathways. Co-occurrence network analysis demonstrated that during summer, the microbial communities on MPs revealed increased connectivity and functional modularity, whereas microbial communities in aquaculture water showed stronger interactions in winter. Additionally, several potential pathogens, including Vibrio and Pseudomonas, were detected in the MPs biofilms.

MPs act as substrates for biofouling and potentially promote the spread of harmful microorganisms. Research indicates that human activities exacerbate MPs pollution in aquaculture environments, significantly increasing their abundance. This study focused on the aquaculture environment of the large yellow croaker (<em>Larimichthys crocea</em>), one of the most extensively farmed fish species in coastal regions. We conducted a comprehensive analysis of microbial diversity on the biofilms covering MPs and in the surrounding aquaculture water, with a focus on the distribution of pathogens on MPs. Furthermore, this study investigated the impact of seasonal variations on the microbial communities within these biofilms. Sequencing analysis revealed that the α-diversity of microbial communities on MPs was lower than that in aquaculture water during winter but higher in summer, indicating a seasonal shift in microbial community structure. PICRUSt predictions suggested that microbes on MPs possess unique metabolic pathways. Co-occurrence network analysis demonstrated that during summer, the microbial communities on MPs revealed increased connectivity and functional modularity, whereas microbial communities in aquaculture water showed stronger interactions in winter. Additionally, several potential pathogens, including <em>Vibrio</em> and <em>Pseudomonas</em>, were detected in the MPs biofilms. These findings underscore the ways in which MPs influence the microbial community structure in aquaculture environments, increasing health risks to the ecosystem.

Benzo[a]pyrene (BaP) is a highly carcinogenic persistent organic pollutant, and biostimulation is an effective strategy to enhance its degradation. This study utilized Bacillus subtilis MSC4 as a BaP-degrading bacterium to investigate the effects of two different fermentation waste liquids as stimulants on BaP degradation. The mechanisms were analyzed and compared at both the cellular and molecular levels. The results showed that the stimulation percentages of yeast Yarrowia lipolytica extracellular metabolites (YEMs) and Lactobacillus plantarum fermentation waste solution (LPS) on the biodegradation of BaP reached 52.8% and 63.4%, respectively, compared to B treatment without biostimulant. Physiological analyses showed that both stimulants repaired cell morphology, more than doubled bacterial biomass, increased EPS secretion, enhanced bacterial activity, and significantly reduced oxidative stress by lowering ROS levels to 75-78% of those in the BaP-stressed group, allowing for repair of oxidative damage. Transcriptomic analysis indicated that both stimulants upregulated pathways related to central carbon metabolism, enhancing cell proliferation and energy supply. Additionally, YEMs promoted electron transport and BaP transmembrane transport and upregulated the synthesis of various monooxygenases, while LPS induced the upregulation of genes encoding quercetin dioxygenase and played a more active role in biofilm formation and enhancing BaP bioavailability. This study reveals the shared and distinct mechanisms by which YEMs and LPS enhance BaP biodegradation, providing theoretical guidance for the application of YEMs and LPS in the bioremediation of BaP-contaminated environments.

The present study fabricated two types of surface-functionalized polydimethylsiloxane sponges (amine-functionalized and extractant-impregnated), and investigated their applicability as a novel separation-recovery method for molybdenum ion (Mo(VI)) in aqueous and HNO3 solutions. An amine-functionalized polydimethylsiloxane (PDMS) sponge was prepared using glycine hydrochloride as a functional ligand, called the Glycine-PDMS sponge, and bis(2-ethylhexyl) phosphate (HDEHP) and 2,2'-(Methylimino)bis(N,N-di-n-octylacetamide) (MIDOA) were used as extractants for the extractant-impregnated sponges, called the HDEHP-PDMS and MIDOA-PDMS sponges, respectively. The adsorption and desorption of Mo(VI) were demonstrated by facile soaking and squeezing of the sponges, which is unavailable in conventional adsorbents. Each PDMS sponge enabled selective Mo adsorption in aqueous and acidic solutions, and had different ligand and HNO3 concentration dependence of the Mo(VI) adsorption capacities. The pseudo-second-order kinetic model was found to be applicable for the Mo(VI) adsorption process on the sponge surfaces. A regression analysis of the isothermal adsorption curves for Mo ions clarified that the adsorption of Mo ions onto all PDMS sponges occurs spontaneously, and that Mo(VI) adsorption mechanism is different depending on sponges; chemisorption for extractant-impregnated sponges and physisorption for an amine-functionalized, respectively. Furthermore, the squeezing of the Mo ion adsorbed PDMS sponges allowed the rapid desorption and recovery of Mo ions into eluent solutions such as deferoxamine B (DFOB) and H2O2 within a few minutes. These results prove that the novel PDMS sponge approach, enabling facile chemical-mechanical adsorption and desorption control of target elements, has great potential in various fields involving the environment, medicine, energy, and so on.

The behavior of chemical warfare agents (CWAs) on urban materials, such as concrete, significantly impacts forensic and military responses to chemical incidents. This study examined the persistence and degradation mechanisms of sarin (GB), soman (GD), and sulfur mustard (HD) on three types of commonly used concrete with varying water-cement ratios. Over two months, we evaluated the effects of concrete composition, temperature, and fragment size on CWA behavior. Half-lives and activation energies for CWA dissipation were calculated under various conditions. Results showed that concrete properties and external temperature strongly influenced dissipation rates. G-series agents underwent rapid hydrolysis, forming methylphosphonates, while HD degradation involved elimination, nucleophilic substitution, and oxidation, producing several previously unreported byproducts. Smaller concrete fragments increased recovery values and accelerated degradation due to greater surface area exposure, and higher temperatures further enhanced dissipation rates, particularly for volatile agents. Differences in dissipation among concrete types were linked to their physical and chemical properties, notably water-cement ratios. This study highlights the challenges of detecting CWAs due to their rapid penetration and transformation in concrete and provides insights for improving sampling, identification, and decontamination strategies under realistic conditions.
