Pharmaceutical active compound (PhAC) residues are considered an emerging micropollutant that enters the aquatic environment and causes harmful ecotoxicity. The significant sources of PhACs in the environment include the pharmaceutical industry, hospital streams, and agricultural wastes (animal husbandry). Recent investigations demonstrated that wastewater treatment plants (WWTPs) are an important source of PhACs discharging ecosystems. Several commonly reported that PhACs are detected in a range level from ng L−1 to μg L−1 concentration in WWTP effluents. These compounds can have acute and chronic adverse impacts on natural wildlife, including flora and fauna. The approaches for PhAC removals in WWTPs include bioremediation, adsorption (e.g., biochar, chitosan, and graphene), and advanced oxidation processes (AOPs). Overall, adsorption and AOPs can effectively remove PhACs from wastewater aided by oxidizing radicals. Heterogeneous photocatalysis has also proved to be a sustainable solution. Bioremediation approaches such as membrane bioreactors (MBRs), constructed wetlands (CWs), and microalgal-based systems were applied to minimize pharmaceutical pollution. Noteworthy, applying MBRs has illustrated high removal efficiencies of up to 99%, promising prospective future. However, WWTPs should be combined with advanced solutions, e.g., AOPs/photodegradation, microalgae–bacteria consortia, etc., to treat and minimize their accumulation. More effective and novel technologies (e.g., new generation bioremediation) for PhAC degradation must be investigated and specially designed for a low-cost and full-scale. Investigating green and eco-friendly PhACs with advantages, e.g., low persistence, no bioaccumulation, less or non-toxicity, and environmentally friendly, is also necessary. © 2024 Elsevier Ltd

Graph Neural Networks (GNNs) frequently face class imbalance issues, especially in heterogeneous graphs. Existing GNNs often assume balanced class sizes, which isn’t true in many cases. Applying them directly to imbalanced data can lead to sub-optimal performance. Traditional oversampling methods, while effective, risk overfitting and face difficulties in reintegrating synthetic samples into the original graph. In this study, we introduce Framework of Imbalanced Node Classification on heterogeneous graph neural network with GAN (FincGAN), a new framework that utilizes oversampling techniques to address class imbalance in heterogeneous graphs. Instead of duplicating existing samples, FincGAN employs a Generative Adversarial Network (GAN) to create synthetic samples and uses deep learning-based edge generators to connect them back to the original graph. Our evaluations on spam user detection in the Amazon and Yelp Review datasets show that FincGAN outperforms baseline models in all essential metrics, including F-score and AUC-PRC score, showing its effectiveness in addressing class imbalance.

A substantial number of people are presently making use of decentralised cryptocurrencies that are built on blockchain technology. These crypto currencies have garnered a lot of interest over the course of the last few years and are currently being used by their users. Being the first use of blockchain technology, Bitcoin has been a resounding success, which drives further research and improvement in the sector concerned with blockchain technology. Bitcoin was the first usage of blockchain technology. Bitcoin, on the other hand, is susceptible to significant performance issues due to the fact that it has a high transaction latency and a limited throughput. The operations of the cryptocurrency are considerably impacted as a result of these concerns. As a result of the fact that other cryptocurrencies that rely on proof-of-work also carry over its deficiencies, there has been an increase in the number of concerns about the scalability of blockchain technology. The fact that this is the case makes scaling blockchain technology more challenging. All during the course of this investigation, an effort is made to analyse and classify the various scaling mechanisms that are now being used for blockchains. In addition to this, we are going to look at a variety of various approaches and present a list of possible solutions to the issue of scalability that the blockchain technology is now dealing.

The Vietnamese Mekong Delta (VMD) has experienced significant morpho logical changes over decades, resulting in profound socioeconomic and environmental conse quences. This study investigated the VMD’s spatial and temporal morphological alterations from 1998 to 2020, utilizing four bathymetric datasets and remote sensing techniques. The ana lysis revealed that the average annual riverbed incision rate in the Tien and Hau Rivers dimin ished from-0.19 m/year (1998–2005) to-0.11 m/year (2005–2017) and further dropped to-0.10 m/year (2017–2020). The upper reaches of the Tien and Hau Rivers exhibited pronounce deepening over the three periods, whereas their lower reaches witnessed a converse trend. Add itionally, the study unveiled the average annual riverbank migration rate along the VMD, ran ging from 5 m/year to-5 m/year during the same examined periods. Notably, the dynamic processes of erosion and deposition intensified between 2017 and 2020. This research aims to provide crucial insights for refining sediment management strategies in the VMD. © 2025 The Author(s).

Fluoride (F) contamination in groundwater affects millions of people across the world. Although several sorbents have been identified for low-cost F removal, the choice of the optimal sorbent is dictated by the specific chemistry of contaminated groundwater. In this contribution, eight prevalent sorbents—activated alumina (AA), calcite, hydroxyapatite-coated calcite (HCC), natural chitosan, chalk, Mg–Al–CO3 layered double hydroxide (LDH), calcined Mg–Al–CO3 LDH (cLDH), and hydrous ferric oxide (HFO)—were categorized on their relative F removal mechanisms, extents, and kinetics from a typical synthetic groundwater, representative of contaminated aquifers of North India. Initially, batch experiments containing sorbents at 4 g·L−1 were conducted at a high F concentration (2.9 mM). The dominant F removal processes were identified by aqueous- and solid-phase characterization of reaction by-products. While chalk and calcite removed F by secondary precipitation of fluorite, HCC removed F by fluorapatite precipitation, and other sorbents removed F by sorption. Depending on the immobilization mechanism identified, the F uptake kinetics on each sorbent was modeled with either pseudo-second order or generalized rate equations. Among sorptive F uptake, cLDH exhibited the highest (10−2.15 mg·g−1·h−1) and HFO showed the lowest (10−4.15 mg·g−1·h−1) rates. Fluoride removal by precipitation was the fastest with chalk at 10−1.3 (h−1) (0.16). Subsequent experiments with AA and HCC at lower initial F concentration (0.42 mM) suggested increased uptake by ∼30x and ∼7x, respectively, relative to uptake in 2.9 mM initial F systems. For AA, apart from the widely-accepted mechanism of adsorption, an unidentified F-containing surface precipitate was formed. HCC was identified as the most promising sorbent with no sludge generation. © 2023 Elsevier Ltd

Transportation sector due to increased pavement lengths is one of main sources of greenhouse gas emissions and energy consumption. With increased environmental awareness and focus on recycling, many studies used recycled material in pavement systems to implement the sustainability. The recycling of waste glass in pavement systems has attracted much interest worldwide due to increased disposal costs. As a pavement material, waste glass could be used as an aggregate substitute in Portland cement concrete, asphalt mixtures and base/sub-base courses. When finely ground, glass can also be used as supplementary cementitious material for substituting partial cement. This paper reviews the different uses of waste glass in pavement systems and the effect of the glass properties on the performance of pavement materials. This review compared the test results reported by different researchers and discusses limitations of using recycled glass in pavement systems along with potential applications. Further, many aspects of the local markets were found to be supportive of diverting recycled glass to concrete products, however, the cost of glass milling and the limited use of concrete products containing glass locally make such diversion uneconomical at the present time. The findings from this review study are expected to advance knowledge in recycling waste glass in pavement systems and offer an effective technique for diverting a large amount of waste glass from landfills. © 2021 Widener University School of Civil engineering.

Plastic waste has become the most significant component of marine debris, while research on traces of marine plastic waste related to the condition of Indonesian waters is still limited. Therefore, this study examines the movement patterns of plastic marine debris in Indonesian waters. Simulations were carried out for one year (2013) using the HAMSOM hydrodynamic and Lagrange trajectory. The approach treated the simulated particles as conservative particles floating at sea. Even though the percentage is small (±16%), Indonesia contributes to transboundary marine debris in the Pacific Ocean, Indian Ocean, and the South China Sea due to the influence of the south equatorial currents moving from north and south of Indonesia. Most of the plastic marine debris remains in Indonesian waters (±80-84%) and moves back and forth due to the influence of the monsoon currents. Therefore, the Java Sea becomes a crossing point and accumulates plastic marine debris. © 2023, The Authors. All rights reserved.

Navigating crowds: Reconsidering visitor recreational experience and crowding preference for a forest park in Taiwan

引用

Forest Policy and Economics 2025年 178卷

作者： Liu, Wan-Yu Yen, Chin-Chun Lee, Rachel S.K. Lin, Chun-Cheng Department of Forestry National Chung Hsing University Taichung402 Taiwan Innovation and Development Center of Sustainable Agriculture National Chung Hsing University Taichung402 Taiwan Department of Industrial Engineering and Management National Yang Ming Chiao Tung University Hsinchu300 Taiwan International Master Program of Smart Manufacturing and Applied Information Science National Chin-Yi University of Technology Taichung411 Taiwan

As forest recreational activities gain popularity, the potential for crowding and activity-based conflicts to diminish sustainable recreational quality becomes a critical concern. Consequently, it is vital to understand the factors shaping recreational preferences and conflict perceptions in natural settings. This study selected Xitou Nature Education Area, Taiwan's most frequented forest park, as a case study to investigate complex relationships among visitor demographics, crowding perceptions, and recreational behaviors. Using a questionnaire and choice experiment, the study explored perceptions of crowding and recreational conflicts within Xitou, alongside visitors' willingness to travel further to avoid crowded conditions. The analysis showed that visitor preferences differed significantly across socioeconomic groups, with age playing a substantial role in shaping motivations and behaviors. While overall perceptions of crowding were moderate, visitors aged 65 and older demonstrated notable tolerance for crowds. Despite the park's high visitation, the incidence of recreational conflict was relatively low, with primary disturbances attributed to visitors resting in various locations, park staff, and group game participants. Contrary to expectations, visitors did not exhibit strong willingness to pay to avoid crowding. Instead, results surprisingly suggested a slight preference for increased social interaction within the park, challenging the general assumption that crowding is always viewed negatively. Drawing from visitor perceptions of overcrowding, we propose enhanced regulations and stricter monitoring for designated resting and picnicking areas to elevate the forest recreation experience. Crucially, this study highlights that effective park management must acknowledge and cater to diverse visitor motivations, whether they seek physical activity, social engagement, or solitude. © 2025
