As antimicrobial resistance continues to pose a significant threat to global health, this study provided a focused examination of the prevalence and behavior of key antibiotic resistance genes in aquatic environments. We investigated the quantitative distribution of intI1, sul1, blaTEM, blaNDM, blaVIM, mcr-1, tetQ, and crAssphage within wastewater influents (n=12), effluents (n=12) and river water samples (n=12), from three municipal wastewater treatment plants and three river locations in an urbanized watershed in Central Thailand over dry and wet seasons. The qPCR method demonstrated that intI1, sul1, blaTEM, and tetQ were most abundant in all samples (6.12 – 7.89 mean log10copies/100 mL), with all genes consistently uniform levels across diverse locations, suggesting the potential for any site to act as a monitoring sentinel. Although there is a significant reduction of ARG concentrations by WWTPs, the persistence of these genes in effluents points to the limited effectiveness of existing treatment methodologies. Temporal data indicated stable ARG concentrations over time, but tetQ levels rose during the wet season, in alignment with the monsoonal climate in Thailand. Additionally, we identified crAssphage, a marker of human sewage contamination, exhibited strong correlations with the more abundant ARGs, implying that human waste contributes significantly to the environmental burden of ARGs. The results of this research highlight the widespread nature of ARGs in water systems and the need for improved treatment and sanitation strategies to mitigate the public health threat posed by antimicrobial resistance. © 2024, The Authors.

Research applications of neural sensing and muscle stimulation have been advanced by the development of bioelectrodes that are biocompatible, flexible and long lasting. The existing metallic made bioelectrodes exhibit extremely high electrochemical resistances that would interfere with the neural-electrode bridge and suffer from mechanical and immunological mismatch. Novel, flexible, implantable bioelectrodes based on MXenes (Ti 3 C 2 ) and Polydimethylsiloxane (PDMS) composite are proposed. Mxenes possess the advantage of having metallic ultra-conductive transition metals consisting of large groups of carbides, nitrides, or carbonitrides, while PDMS has inherent biostability, flexibility and biocompatibility. In the current research, PDMS has been used as the supporting matrix for conductive fillers such as PMMA, PEDOT, and Mxenes. A series of characterization techniques were performed such as Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetry (CV) and mechanical testing. The average results of triplicate samples exhibited samples' bulk impedance of 0.913 kΩ, an impedance of 1.612 MΩ, at 1 kHz frequency and a conductivity of 1.41x10 -4 S/cm, charge storage capacity of 0.056 mC/cm 2 and Young's modulus of 3.81 MPa.

Genji-firefly has been one of the key symbols of rural environmental conservation. The species lives underwater as larvae, in the soil when they pupate, and emerges on the ground as adults. Because the habitat conditions of larvae and adults differ greatly, the habitat requirement of Genji-firefly must be clarified over a wide range from instream to the surrounding riparian environment. In this study, we developed a habitat suitability model for Genji-firefly by relating the number of individuals to local landscape features surveyed in a small river in an agricultural watershed. For habitat modelling, Random Forests, a well-known highly predictive machine learning method, was used to model species distributions and to extract quantitative information on their ecological characteristics. As a result, a good agreement was found between observed and modelled number of individuals, although some issues still remain for the test data. We were able to extract local landscape features that characterize the habitat suitability of adult firefly. In future, we plan to deepen our habitat suitability assessment by taking into account uncertainties such as noise originated from absent data.

Drought is a climatic phenomenon that has increased in severity over time. This study analyzed drought spread in the Alto Patía basin (13,047 km2) in South America, applying the Standardized Precipitation Index (SPI), Vegetation Health Index (VHI), and Streamflow Drought Index (SDI) to assess meteorological, agricultural, and hydrological drought, respectively. Synchronous and asynchronous correlations were estimated, and Wavelet analysis was conducted to verify relationships among drought types. Results show that the lag between drought types varies based on the intensity, temporal continuity, and spatial extent of meteorological drought. A lag of zero months (1–2 months) was observed between meteorological and hydrological drought when moderate (severe) meteorological drought partially (fully) covers the basin. Agricultural drought, however, does not always correspond to meteorological drought during isolated rainfall events. As the first study in Colombia to systematically connect these drought types, this research addresses a gap in understanding how drought impacts progress across systems in regions with complex rainfall patterns. These findings offer critical insights into the interdependencies among drought types, supporting enhanced drought monitoring and early warning systems in similar climatic regions. By identifying specific lags between meteorological and hydrological droughts, this study provides practical guidance for land management, water conservation, and crop planning, offering a foundation for future research on drought resilience strategies.

Ecosystems such as wetlands have karst groundwater as their primary source of preserving their services and functions. Karst systems are complex hydrogeological systems that are difficult to study because of their complicated functioning mechanism, which requires an interdisciplinary effort based on hydrodynamic assessment and characterization of the hydrogeology of the system. The study area is the Ramsar wetland Ciénaga de Tamasopo (Mexico), which is dependent on the discharge of karst groundwater that is affected by water extraction of extensive sugarcane agriculture and is also the main water source for the rural towns. Hydrogeochemical and isotopic tools further suggest that at least two distinct sources contribute to the groundwater composition in the Ciénaga de Tamasopo basin. One corresponds to meteoric water recharging the aquifer through karst structures of the El Abra Fm. and Tamasopo Fm. inferring a local flow with an isotopic composition of δ18O (− 4.75 to − 4.20‰) and δ2H (− 29.12 to − 23.86‰). The second is associated with regional-intermediate flow, indicating that the water has an enrichment of heavy δ18O (− 6.90 to − 6.65‰) and δ2H (− 41.37 to − 40.41‰) isotopes circulating in the Guaxcamá Fm. EC and temperature variations were evaluated, determining that the EC tends to increase in the rainy season because of the mixing of local and intermediate flows and that there is evidence of temperature increase. The chemical analysis identified the dominant processes in this karst system as dissolution–precipitation of calcite, dolomite, and gypsum by water–rock interaction, mixing, and evaporation. This study facilitated the development of a conceptual model for understanding groundwater movement in warm and sub-humid climate karst systems. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

Studies have evaluated the impact of environmental exposure to neurotoxic metals on developmental delays (DDs). However, comprehensive understanding regarding the associations between parental and postnatal exposure to metal mixtures and the occurrence of DDs in offspring is limited. In this study, we assessed the relationships between parental and postnatal exposure to three metals (arsenic [As], cadmium [Cd], and lead [Pb], levels of which were measured in toenails) and suspected DDs (SDDs) in preschool children within a Taiwanese longitudinal birth cohort. In total between 2017 and 2021, 154 pairs of parents and their children under the age of 6 years were recruited, and 462 toenail samples and 154 completed questionnaires were collected. Metal concentrations in toenails were quantified using inductively coupled plasma-mass spectrometry after acid digestion of the toenails. We applied multivariable logistic regression and Bayesian kernel machine regression to evaluate the overall effect and to identify key components of the metal mixture that were associated with the SDD risk. Higher concentrations of As, Cd, and Pb were found in the toenails of the parents of children with SDDs compared with the toenails of the parents of children without SDDs. Our examination of the combined effects of exposure to the metal mixture revealed that As concentration in the father’s toenail and Cd concentration in the mother’s toenail were positively correlated with the risk of SDDs in their offspring. Notably, the effect of exposure to the metal mixture on the risk of SDDs was stronger in boys than in girls. Our findings suggest that parents taking measures to minimize their exposure to metals might enhance their children’s developmental outcomes. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

Nature-Based Solutions 2024年 5卷

作者： Bressane, Adriano Pinto, Joao Pedro da Cunha Medeiros, Líliam César de Castro São Paulo State University (UNESP) Institute of Science and Technology São José dos Campos city Brazil Graduate Program in Civil and Environmental Engineering São Paulo State University (UNESP) Brazil

Statement of problem: Green gentrification is an emerging issue, where Urban green space (UGS) upgrades lead to higher living costs, displacing lower-income residents, raising concerns about accessibility, sustainability, and equity. This phenomena challenges the inclusive and equitable development of urban environments. Purpose: Through an integrative analysis of existing literature, this study aims to address a significant gap in current research by exploring how Nature-Based Solutions (NbS) can more effectively counteract the adverse effects of UGS gentrification. Method: Utilizing a scoping literature review, the research analyzes articles from 2015 to 2024 to synthesize insights for a more equitable urban development. Results: Findings reveal diverse lessons learned and strategies for countering green gentrification across different urban settings worldwide. However, a significant number of studies predominantly focus on the Global North, primarily in Europe and North America, which may lead to a regional bias. Practical implications: The results provide insights for policymakers, urban planners, and communities, guiding the creation of more inclusive and sustainable urban green spaces. Future directions: Further research should focus on developing quantitative metrics to evaluate the effectiveness of NbS in mitigating urban gentrification and expanding the geographic focus to include more underrepresented regions. © 2024 The Author(s)
