We investigate how green energy supply chain vulnerabilities (GESCV) amplify climate-related risk exposure among major energy firms across 36 countries from 2010 to 2023. Our benchmark model substantiates that GESCV amplifies corporate exposure to climate-related risks, with risk quantified using the Fama-French Three-Factor model. The adverse effects remain pronounced in developing countries, fossil fuel-based firms, and high-climate policy uncertainty groups. Mechanism-wise, GESCV heightens climate-related risk exposure by diminishing total asset turnover and worsening investment inefficiency. Further analysis reveals that governance quality is the only significant factor mitigating the detrimental link between GESCV and climate risk exposure, whereas women's political empowerment and environmental technologies exhibit minimal influence. Additionally, a difference-in-differences (DID) model confirms that the Paris Agreement has played a role in easing the negative consequences of GESCV on climate-related risk exposure. These findings underscore the need for governance enhancements, diversified supply chain strategies, and policy-driven investments in green technologies as essential measures to curb climate risks during the global energy transition.

Halohydroxybenzonitriles (HHBNs) were reported to exist in drinking water as an emerging group of nitrogen-containing aromatic disinfection byproducts (DBPs). The involvement of binding energy with catalase (CAT) as one of molecular descriptors in the quantitative structure-activity relationship model for HHBN cytotoxicity supported that oxidative stress is highly possible to be an essential cytotoxicity mechanism for HHBNs, and the disruption of cellular redox homeostasis may be partly attributed to their interactions towards CAT. However, the relevant evidence is lacking as yet. Thus, in this study, typical biomarkers for oxidative stress and damage in HHBN-treated cells were examined, and the binding interactions between HHBN and CAT were explored. Results indicated that upon exposure to 3,5-dibromo-2-hydroxybenzonitrile, the antioxidant system (e.g., CAT, superoxide dismutase, and glutathione) was disrupted, and excessive reactive oxygen species gave rise to oxidative DNA damage, which further resulted in cell apoptosis. Moreover, the binding interaction between CAT and 3,5-dibromo-2-hydroxybenzonitrile could change the structure and activity of CAT, with the formation of complexes primarily dependent on van der Waals forces and hydrogen bonding. A positive correlation was observed between HHBN cytotoxicity and inhibitory potency on the biological function of CAT, and some unidentified iodinated HHBNs warrant special attention in future owing to their potential high cytotoxicity. The above results contribute to a better understanding of the toxic mechanisms of emerging HHBN DBPs.

Microplastics (MPs) pollution and metal contamination are two prominent environmental stressors with multifaceted implications for aquatic life and ecosystem health. However, the underlying toxicological mechanisms of MPs and metals co-exposure on fish reproduction processes are largely unknown. In this study, zebrafish (Danio rerio) were exposed to MPs (2 mg/L), copper (25 μg/L, Cu25), and their mixture (Cu25 + MPs), for 30 days. The oxidative stress response, along with the expression profile of the hypothalamic-pituitary-gonadal (HPG) axis-related genes in the brain and gonad of zebrafish, were evaluated.
The findings demonstrated that exposure to MPs and Cu affects the antioxidant system of zebrafish brain and gonads, inhibiting GPx in individuals exposed to MPs, Cu25, and their mixture. The gene expression analysis revealed dysregulation of the HPG axis-related genes. Specifically, the androgen receptor (ar), estrogen receptor 1 (esr1), follicle-stimulating hormone (fsh), and gonadotropin-releasing hormone 2 (gnrh2) were upregulated in the brain, whereas the genes esr2a, ar, cytochrome P450 family 11 subfamily A member 1 (cyp11a) and cyp19a were upregulated in the gonads. Both the biochemical and gene expression results showed that the brain and gonads were differently affected by MPs and Cu with the effects varying with fish gender. Furthermore, the mixture exposure affected the brain the most, and the individual pollutants affected the gonads the most.
Overall, this study highlights that MPs, alone or combined with Cu, adversely affect the HPG axis of zebrafish, posing a potential threat to the reproduction of fish populations.

In Thailand, the recurring environmental issue of high PM2.5 concentrations from December to April is partly due to pre-harvest sugarcane burning. This practice severely impacts the environment, economy, and public health. To combat this, the Thai government aims to eliminate pre-harvest sugarcane burning by 2024 through a voluntary monetary incentive scheme. This study employs a quasi-experimental approach in eight Thai regions to evaluate the policy's effectiveness. Using the strategy method, this paper aims to determine the Minimum Acceptable Price (MAP) and Willingness to Accept (WTA) for farmers to switch from selling burned to fresh sugarcane. Findings indicate that the positive incentive of THB 120 per ton for fresh sugarcane influences 88.77% of farmers to cooperate. To achieve over 90% compliance, the subsidy should increase to THB 150 per ton, requiring an additional budget of approximately THB 2,100 million per crop season. Conversely, the negative incentive measure, which follows the “polluter pays principle,” involves deducting THB 30 per ton from the sale price of burned sugarcane. This results in 82.17% of farmers switching to fresh sugarcane. To reach the 90% effectiveness target, the deduction should increase to THB 50 per ton, potentially leading to a fine collection of THB 378.85 million based on the previous season's production. This study's findings will inform future policy adjustments and contribute to academic knowledge on farmers' responsiveness to public policies.

The urgent need to tackle climate change and encourage responsible consumption patterns within the framework of environmental management and sustainable development has amplified the significance of understanding how sustainable consumption practices are passed down through generations. The purpose of this research is to expand the understanding of the intergenerational transmission of sustainable consumption. Drawing upon consumer socialization theory and taking a reverse socialization perspective, our research explores how sustainable consumer attitudes and behaviors are transmitted across generations, particularly within mother-daughter dyads in a collectivistic culture: China. Four factors—intra-family communication effectiveness, receptivity to green marketing communication, green subjective knowledge, and peer conformity—are examined as potential influencers of the intergenerational transmission process, using the co-orientational model and the nominal dyad method. After quantifying dyadic raw agreement scores and accounting for nominal effects, the current findings reveal the presence of intergenerational similarity in sustainable consumer attitudes and behaviors and demonstrate that higher green receptivity, subjective knowledge, and intra-family communication between mothers and daughters enhances intergenerational agreement, while stronger peer conformity on daughters diminishes intergenerational transmission. Further, a significant reverse environmental transmission effect from daughters to mothers was documented, underscoring the role of younger generations in promoting sustainable practices within families. Overall, this research sheds light on the relational dynamics of sustainability practices in families. It also highlights the importance of intergenerational impacts in promoting sustainable consumption within dyadic relationships, providing invaluable guidance for marketing and environmental managers seeking to leverage these dynamics.

Microorganisms are vital components of airborne particles and are closely linked to human health and industrial processes. As industrialization advances, factories are exacerbating their impact on environmental microbial communities, an area where our understanding remains limited. In this study, we investigated air microorganisms surrounding Chinese baijiu fermentation facilities, aiming to explore the dispersal mechanisms of fermentation-sourced microbiota and their potential impacts on local airborne microbial communities. The results revealed a significant overlap between microbial communities from fermentation processes and the surrounding air, with 14 genera commonly found in both habitats, suggesting widespread and substantial dispersal of factory microorganisms. Due to this dispersal, fermentation-sourced Saccharopolyspora and Streptomyces have become central nodes in the airborne microbial network. Environmental factors played a pivotal role in the microbiota dispersal process. Higher temperatures may facilitate microbial proliferation and increase the dispersal of fermentation microorganisms (r = 0.30, P < 0.01), while higher wind speeds may lead to a dilution effect and limit the uniform dispersal of microorganisms (r = −0.22, P < 0.05). Furthermore, air-resident microorganisms restricted the proliferation of fermentation microorganisms (r = −0.60, P < 0.001). These results confirm the modifying effect of fermentation facilities on environmental microbial communities and establish a theoretical foundation for optimizing factory site selection.

Macrophytes are a critical component of freshwater ecosystems, harboring significant biodiversity and providing essential resources and services. However, their habitat faces multifaceted challenges from climate change, local anthropogenic disturbance, and biological invasions. Here, we aim to provide local management suggestions under both current and future higher temperature regimes. Using joint species distribution modeling (JSDM), we integrate comprehensive presence-absence data with environmental variables and ecological traits to predict the distributions and diversity of 44 vascular aquatic plant and charophyte species in three shallow lakes (435 sites in total) in southwestern France. The environmental variables considered included physical properties (including current surface temperature and a 2 °C warming scenario), anthropogenic disturbance, shoreline curvature, underwater topography, and the occurrence rate (temporary or permanent) of water and wetness. Subsequently, we use percentile-threshold-based spatial prioritization to identify conservation management hotspots. Our results show that macrophyte habitat suitability is largely influenced by land-use and human accessibility. Moreover, macrophyte habitat suitability and native species diversity generally decrease across lakes under warming. However, the decrease in habitat suitability is greater for native isoetid species than for invasive species—suggesting a potential forthcoming cascade of changing community composition, higher lacustrine trophic states, and impaired provisioning of ecosystem services. Therefore, we suggest immediately adopting adaptive management principles at the identified conservation management hotspots, including the control of and targeted monitoring for invasives as well as conservation and restoration measures for native species, in particular isoetids.
大型营养体是淡水生态系统的重要组成部分，具有重要的生物多样性，并提供重要的资源和服务。然而，它们的栖息地面临着气候变化、当地人为干扰和生物入侵等多方面的挑战。在此，我们旨在为当前和未来较高温度条件下的本地管理提供建议。利用物种联合分布模型（JSDM），我们将综合存在-消失数据与环境变量和生态特征相结合，预测了法国西南部三个浅湖（共 435 个地点）中 44 种维管束水生植物和叶绿体物种的分布和多样性。所考虑的环境变量包括物理特性（包括当前的地表温度和 2 °C 的升温情景）、人为干扰、海岸线曲率、水下地形以及水和湿度的出现率（临时或永久）。随后，我们使用基于百分位阈值的空间优先排序法来确定保护管理热点。我们的研究结果表明，大型藻类生境适宜性在很大程度上受土地利用和人类可达性的影响。此外，在气候变暖的情况下，各湖泊的大型藻类生境适宜性和本地物种多样性普遍下降。然而，与入侵物种相比，本地等位基因物种的栖息地适宜性下降幅度更大--这表明可能即将发生一连串的群落组成变化、湖泊营养状态升高以及生态系统服务供应受损。因此，我们建议在已确定的保护管理热点地区立即采用适应性管理原则，包括控制和有针对性地监测入侵物种，以及保护和恢复本地物种（尤其是等长目物种）的措施。

Although multiphase catalysts with large sizes exhibit excellent recyclability and low toxicity in heterogeneous Fenton reactions, their reactivity, reusability and storage stability for degradation of organic contaminants still need improvement, which is essential for treating complex wastewater and ensuring environmental sustainability. In this study, the waste cotton textiles were firstly used as the carbon source to generate a novel millimeter-sized catalyst (Fe/Fe3C@HBC) with a honeycomb-like structure, which could effectively activate H2O2 to realize rapid removal of ofloxacin (OFL) (100% in 10 min). It achieved remarkable removal performance across a broad temperature range (4–40 °C) and high-concentration OFL. It even demonstrated excellent removal towards other typical contaminants (Tetracycline, Ciprofloxacin, Methylene Blue, Rhodamine B, Malachite Green), showing outstanding storage stability, physical structural stability, reusability and separation characteristics. Whereafter, its removal mechanism was also explored, showing that it was entirely dependent on the degradation by the reactive oxygen species (ROS), including •OH, O2•- and 1O2, as well as the persistent free radicals from the catalyst. Moreover, the honeycomb-like structure promoted the effective utilization of H2O2, facilitated the generation of •OH and expedited the accumulation of OFL on the catalyst surface. Fe/Fe3C (inside of the catalytic instead of in the reaction solution) was essential for the degradation. Finally, the OFL degradation pathways and toxicity predictions were also proposed. Overall, this innovation supports cleaner water resources and enhances public health, demonstrating a significant step forward in environmental remediation technologies.

It even demonstrated excellent removal towards other typical contaminants (Tetracycline, Ciprofloxacin, Methylene Blue, Rhodamine B, Malachite Green), showing outstanding storage stability, physical structural stability, reusability and separation characteristics. Whereafter, its removal mechanism was also explored, showing that it was entirely dependent on the degradation by the reactive oxygen species (ROS), including <sup>•</sup>OH, O<sub>2</sub><sup>•-</sup> and <sup>1</sup>O<sub>2</sub>, as well as the persistent free radicals from the catalyst. Moreover, the honeycomb-like structure promoted the effective utilization of H<sub>2</sub>O<sub>2</sub>, facilitated the generation of <sup>•</sup>OH and expedited the accumulation of OFL on the catalyst surface. Fe/Fe<sub>3</sub>C (inside of the catalytic instead of in the reaction solution) was essential for the degradation. Finally, the OFL degradation pathways and toxicity predictions were also proposed. Overall, this innovation supports cleaner water resources and enhances public health, demonstrating a significant step forward in environmental remediation technologies.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"378 ","pages":"Article 124778"},"PeriodicalIF":8.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534878","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}

The assembly mechanisms of riverine biofilm communities in river systems represent a central question in aquatic microbial ecology. However, the influence of turbulence on the assembly of generalists and specialists within biofilms remains poorly understood. This study aimed to address this gap by examining a river with multiple spur dikes, using high-throughput sequencing, ecological network analysis, and partial least squares path modeling to explore the assembly process and community structure of biofilms. The results revealed that turbulence intensity (0.029 m/s) and kinetic energy (0.0018 m2/s2) were significantly higher at the heads of spur dikes compared to the tails. Notably, hydrodynamic parameters explained 6.50% of biofilm community variance, highlighting their underappreciated role as deterministic drivers of microbial assembly. Habitat specialists exhibited heightened sensitivity to hydrodynamic fluctuations, occupying central positions in co-occurrence networks. Additionally, turbulence intensity and kinetic energy emerged as the primary drivers of community assembly, influencing critical ecological processes such as homogeneous selection, drift and dispersal limitation. At the head of spur dikes, a high turbulence region, the weakened impact of homogeneous selection, combined with an increase in dispersal limitation, created conditions that particularly favored habitat generalists. Conversely, low turbulence dike tails supported specialist proliferation via strengthened deterministic selection and nutrient-driven niche partitioning. Furthermore, the partial least squares path modeling confirmed that turbulence dominates the assembly process of microbial specialists and generalists. This study revealed the pivotal role of turbulence in shaping biofilm assembly and driving the spatial differentiation of generalists and specialists, offering fresh insights into the complex interplay between hydrodynamics and microbial ecology in rivers impacted by hydraulic structures. These findings significantly enhance the understanding of biofilm assembly mechanisms and their broader implications for effective river ecosystem management.

Chlorine-based disinfectants are often used to achieve the required microbiological effluent limits and to ensure appropriate public health protection against waterborne pathogens; however, they can produce potentially harmful disinfection by-products and negatively affect the ecosystem of effluent receiving bodies. Peracetic Acid (PAA) and Performic Acid (PFA) are emerging as promising disinfectants in water treatment due to their effectiveness against a wide spectrum of microbes and minimal environmental impact, addressing some of the limitations associated with traditional chlorine-based disinfectants. In present work, we present and analyze the secondary effluent wastewater bench test results for demand, decay, and microbial inactivation kinetics of PAA, PFA, and sodium hypochlorite (SH) from six North American water resource recovery facilities (WRRFs) using an advanced fitting method based on uncertainty ellipses. To evaluate the effectiveness and suitability of alternative disinfectants, the inactivation performance of the PAA and PFA against E. coli, fecal coliform and enterococci were investigated and compared to the inactivation performance of SH. When comparing the integral-CT or ICT (i.e., integral of disinfectant concentration over time) based exposure performance of PFA against SH and PAA, it exhibits the superior inactivation performance in the limited ICT values for all the fecal indicator bacteria. For instance, to achieve a 2-log10 reduction of E. coli inactivation, ICT required for PFA ranges from approximately 1 to 3.6 mg min/L, for PAA from 8.2 to 21 mg min/L and for SH from 0.6 to 22 mg min/L across six WRRFs. Additionally, the residual concentration of the disinfectant dosage was examined to understand the uncertainties in demand/decay model development. Developing a confidence region provides guidance for conducting future experiments to improve the accuracy and reliability of subsequent tests. Later, the results of demand/decay and inactivation kinetics are utilized in process modeling, considering four dosing control schemes. Our findings indicate that the advanced dosing scheme, which accounts for wastewater variability and the hydraulic characteristics of the contact chamber, reduces disinfectant usage by up to 36% compared to the conventional flow pacing strategy while ensuring compliance with regulatory standards. Additionally, the advanced control scheme demonstrated steady and reliable performance in achieving target microbial limits throughout its operation.
