Background

Understanding the release characteristics of soil colloids is a prerequisite for studying the co-transport of colloids and pollutants in subsurface environment. As a crucial agricultural management measure, fertilization not only alters the material composition of farmland soil, but also significantly regulates the properties and release patterns of soil colloids. This study systematically investigated the regulatory mechanism of short-term cattle manure fertilization on the macroscopic release and microscopic properties of soil colloids with different particle sizes, providing a theoretical foundation for subsequent research on the fate and transport of agricultural non-point source pollutants.

Results

The colloids in natural agricultural soil primarily consist of inorganic components. Graded extraction of the colloids has revealed that the combined proportion of colloids with particle sizes of 1–2 μm and 0.45–1 μm accounts for approximately 80.5%. Applying cattle manure inhibits the release of soil colloids, and the content of large particle size (1–2 μm) components increases. The content of organic colloids is increased due to the high total organic carbon (TOC) in cattle manure, particularly those with a particle size less than 1 μm. The characterization of organic colloid components revealed a significant increase in aromatic carbon and oxygen-containing functional groups, while the aliphatic content decreased. The response sequence regarding changes in functional groups within organic colloids induced by fertilization was as follows: –CH3, –CH2 > C–O > –OH > C=C. Fertilization promotes the release of 1:1-type inorganic mineral colloids, increasing the content of poorly crystalline minerals. The retention of aromatic carbon and oxygen-containing functional groups by poorly crystalline mineral colloids served as the primary mechanism leading to their increased content levels. Changes in environmental factors significantly impacted the release and properties of soil colloids. Conditions such as low cationic valence, high ionic strength, and high pH promoted the release of soil colloids.

Conclusions

The short-term fertilization resulted in a reduction in the release of soil colloids and brought about significant alterations in their particle size composition and properties. The findings of this study provide valuable insights into understanding the impact of fertilization-induced colloid release on the environmental behavior of agricultural non-point source pollutants.

背景了解土壤胶体的释放特性是研究地下环境中胶体与污染物共迁移的前提。施肥作为一项重要的农业管理措施,不仅改变了农田土壤的物质组成,而且对土壤胶体的性质和释放模式具有重要的调控作用。本研究系统研究了短期牛粪施肥对不同粒径土壤胶体的宏观释放和微观性质的调控机制,为后续农业非点源污染物的归宿与迁移研究提供了理论基础。对胶体进行分级萃取后发现,粒径为 1-2 μm 和 0.45-1 μm 的胶体所占比例之和约为 80.5%。施用牛粪抑制了土壤胶体的释放,大粒径(1-2 μm)成分的含量增加。牛粪中的总有机碳(TOC)含量高,特别是粒径小于 1 μm 的有机胶体含量增加。有机胶体成分的表征显示,芳香碳和含氧官能团的含量显著增加,而脂肪族含量则有所减少。施肥引起的有机胶体中官能团变化的反应顺序如下:-CH3, -CH2 > C-O > -OH > C=C。施肥促进了 1:1 型无机矿物胶体的释放,增加了弱结晶矿物的含量。贫晶矿物胶体保留芳香碳和含氧官能团是导致其含量增加的主要机制。环境因素的变化极大地影响了土壤胶体的释放和特性。低阳离子价、高离子强度和高 pH 值等条件促进了土壤胶体的释放。这项研究的结果为了解施肥引起的胶体释放对农业非点源污染物环境行为的影响提供了宝贵的见解。

Climate change, caused by both natural and human activities, poses significant threats to global health, including rising temperatures, extreme weather events, and environmental disruptions. The One Health concept, emphasizing the interconnectedness of human, animal, and environmental health, is crucial in addressing these challenges. Climate change is linked to the emergence and resurgence of infectious diseases, resulting in substantial economic losses worldwide due to outbreaks, floods, and disrupted trade, among other factors. Therefore, it is crucial to adapt to this changing climate to safeguard One Health. By implementing a One Health approach, we can effectively address the consequences of climate change and make substantial contributions to health and food safety. This approach also holds the potential to mitigate economic losses, particularly in low and middle-income countries. Additionally, in the future, research interventions based on the One Health framework may offer sustainable solutions to combat climate change.

由自然和人类活动引起的气候变化对全球健康构成重大威胁,包括气温上升、极端天气事件和环境破坏。强调人类、动物和环境健康相互关联的 "一个健康 "理念对于应对这些挑战至关重要。气候变化与传染病的出现和复发有关,传染病的爆发、洪水和贸易中断等因素在全球范围内造成了巨大的经济损失。因此,适应不断变化的气候以保障 "一个健康 "至关重要。通过实施 "一个健康 "方法,我们可以有效应对气候变化的后果,为健康和食品安全做出重大贡献。这种方法还有可能减轻经济损失,特别是在中低收入国家。此外,在未来,基于 "一体健康 "框架的研究干预措施可能会为应对气候变化提供可持续的解决方案。

This study evaluated the source apportionment and level of contamination with potential toxic elements (PTEs)—As, Cd, Cr, Cu, Ni, Pb and Zn—in a riparian zone of the Sava River by calculating the Enrichment Factor (EF) and the Geo-Accumulation Index (Igeo). The study analysed the non-carcinogenic and carcinogenic health risks to both adults and children in the local population. Soil and sediment samples collected during high and low water events from 12 sites along 945 km of the river were screened. Elevated soil contents of As, Cr, Cu, Ni, and Zn were observed along the middle and lower stretches from Županja (ZUP) to Belgrade (BEO), and an elevated Cu content was detected in the upper stretch Čatež (CAT), highlighting these elements as a potential risk for the human population. Elevated As, Cd Cr, Ni, and Zn levels in the sediment were also detected, with the Ni content three times higher than the Permissible Exposure Limit (PEL) values, indicating high contamination. The study established that As, Cr, and Ni primarily originate from geological sources; Cu, Pb, and Zn are predominantly from anthropogenic sources; and Cd originates from both geological and anthropogenic sources. Although the EF and Igeo varied along the entire river stretch, they were significantly higher for most elements in the lower stretch, indicating intensive anthropogenic contamination and potential health risks. The carcinogenic and non-carcinogenic risks associated with soils and sediments during high and low water events did not imply a potential risk for adults. However, As, Cd, Cr, and Pb potentially pose the greatest non-carcinogenic risk for children in both high and low water events, with ingestion as the main route of exposure. According to our findings, the elevated concentrations of As, Cd, Cr, and Pb in the Sava River basin (SRB) pose a significant potential health risk to the local population based on several factors: the high levels of these elements, their potential contamination risk as determined by the EF and Igeo, and their bioavailability and solubility. Although the cumulative Total Hazard Index (THI) and Total Carcinogenic Risk (TCR) values are low, particularly in the lower stretch of the Sava River, these elements still present a high potential health threat.

本研究通过计算富集因子 (EF) 和地质累积指数 (Igeo),评估了萨瓦河沿岸地区潜在有毒元素 (PTE) --砷、镉、铬、铜、镍、铅和锌的来源分布和污染程度。该研究分析了对当地成人和儿童的非致癌和致癌健康风险。研究人员对沿河 945 公里的 12 个地点在丰水期和枯水期采集的土壤和沉积物样本进行了筛选。从Županja(ZUP)到贝尔格莱德(BEO)的中下游河段的土壤中发现砷、铬、铜、镍和锌的含量升高,上游河段 Čatež (CAT) 的铜含量升高,凸显了这些元素对人类的潜在风险。此外,还检测到沉积物中的砷、镉、铬、镍和锌含量升高,其中镍含量比允许接触限值(PEL)高出三倍,表明污染严重。研究确定,砷、铬和镍主要来自地质来源;铜、铅和锌主要来自人为来源;镉既来自地质来源,也来自人为来源。虽然整个河段的 EF 值和 Igeo 值各不相同,但在下游河段,大多数元素的 EF 值和 Igeo 值都明显偏高,表明人为污染严重,对健康构成潜在风险。在高水位和低水位事件中,与土壤和沉积物相关的致癌和非致癌风险并不意味着对成人有潜在风险。然而,在高水位和低水位事件中,砷、镉、铬和铅可能对儿童造成最大的非致癌风险,而摄入是主要的接触途径。根据我们的研究结果,萨瓦河流域(SRB)中高浓度的砷、镉、铬和铅对当地居民的健康构成了巨大的潜在风险,这主要基于以下几个因素:这些元素的高浓度、EF 和 Igeo 确定的潜在污染风险以及它们的生物利用率和可溶性。尽管累积总危害指数 (THI) 和总致癌风险 (TCR) 值较低,尤其是在萨瓦河下游,但这些元素仍对健康构成了较高的潜在威胁。

Background

Irrigation with low-quality water without considering the acceptable levels negatively impacts not only humans, but also extends to the whole surrounding ecosystem. The current research is a comprehensive-integrated appraisal of the irrigation water quality gathered from El-Batts drain in Fayoum Governorate, from September 2021 to June 2022, together with the drain sediments and the soils adjacent to it. The characteristics (physical, chemical and biological), and the risk fate of some heavy metals (As, B, Cr, Cu, Zn, Cd, Pb, Ni, Fe and Mn) were measured. Moreover, the risks of the studied pollutants were assessed using many indices: irrigation water quality index (IWQI), contamination factor (Cf), degree of contamination (Cd), Salinity indices and Zn equivalent (ZE). Additionally, kinetic studies of the inorganic pollutants were evaluated to determine their availability and impact on the surrounding environment.

Results

Data from IQWI showed that water in all five sites was assumed to be very bad and unsuitable for usage with a general average (14.62 and 25.35) in all four seasons. ZE exceeds the critical level of 250, which means there is a risk of soil contamination.

Conclusions

The elevated levels of heavy metals, microbial enzymes, pathogenic fecal coliform and Salmonella reflect bad and direct risk of dealing with such water in irrigation and its effect on the soil ecosystem and the growing crops. Most of the tested parameters exceeded the acceptable levels of the Egyptian Governmental Law Guidelines, WHO and FAO, which may threaten aquatic life. Best managements practices and remediation techniques should be applied to minimize the hazards in such waters.

背景使用低质水灌溉而不考虑可接受水平不仅会对人类造成负面影响,还会影响到周围的整个生态系统。目前的研究是对 2021 年 9 月至 2022 年 6 月期间从法尤姆省 El-Batts 排水沟收集的灌溉水水质以及排水沟沉积物和邻近土壤的综合评估。测量了一些重金属(砷、硼、铬、铜、锌、镉、铅、镍、铁和锰)的特性(物理、化学和生物)和风险归宿。此外,还使用多种指数评估了所研究污染物的风险:灌溉水质量指数(IWQI)、污染因子(Cf)、污染程度(Cd)、盐度指数和锌当量(ZE)。此外,还对无机污染物的动力学研究进行了评估,以确定其可用性及其对周围环境的影响。结果 IQWI 的数据显示,所有五个地点的水质都很差,不适合使用,所有四个季节的平均值为(14.62 和 25.35)。结论重金属、微生物酶、致病性粪大肠菌群和沙门氏菌含量的升高反映了在灌溉中使用这些水的不良直接风险及其对土壤生态系统和作物生长的影响。大多数检测参数都超过了埃及政府法律准则、世界卫生组织和联合国粮农组织规定的可接受水平,可能会对水生生物造成威胁。应采用最佳管理方法和补救技术,将此类水体的危害降至最低。

Background

Discharge of large amounts of untreated industrial effluent into water bodies pose significant environmental challenges worldwide. This is due to the limitations of traditional wastewater treatment methods in the treatment of recalcitrant organic pollutants. Fenton processes involves the generation of hydroxyl radicals that are well suited to degrade organics in effluent water. This study focuses on reducing slag generation during Fenton processes and enhancing the reuse of nano-zero-valent iron (NZVI) through the immobilization of NZVI on activated carbon cloth (ACC) through a chitosan (CH) linker with phenol as a model pollutant.

Results

Microstructural and spectroscopic techniques were employed to study the materials prepared and 37.5 wt% iron loading was achieved. Phenol degradation of 96.3% at 40 °C at pH of 3.0 with 50 mM H2O2 was achieved using ACC-CH-NZVI. Adsorption and degradation studies carried out using ACC-CH-NZVI catalyst revealed that phenol adsorption onto ACC-CH-NZVI fits the Langmuir isotherm model, following the pseudo-second-order kinetic model and first-order reaction kinetics. Thermodynamic studies indicate the non-spontaneous, endothermic and irreversible nature of the removal process. Comparing ACC-CH-NZVI with ACC and ACC-CH, phenol removal using ACC drops from 87.8 to 39%, while using ACC-CH, the removal efficiency drops from 73 to 20.9% and using ACC-CH-NZVI, phenol removal drops from 96.3 to about 70% and total organic carbon removal drops from 79 to about 60% with minimal iron leaching, highlighting the superior performance of ACC-CH-ZVI and the role of NZVI in enhancing phenol removal.

Conclusions

Background

African countries are among the most vulnerable and affected by climate change. Comprehending climate change poses a major hurdle for the African population, politicians, and the African Union alike, presenting a substantial challenge for all involved. It is generally accepted that universities and other higher education institutions must play a leading role as drivers of change. Therefore, it is very important that African universities educate students about both mitigation and adaptation measures, develop the necessary initiatives to foster research in climate change-related topics and promote cooperation and alliances with key stakeholders.

Results

This research reports on a study aimed at identifying the extent to which higher education institutions in Africa are engaging in efforts to deal with the challenges posed by climate change. The objectives were accomplished through a mixed method approach, incorporating a review of literature, an international survey, and the inclusion of selected case studies from African universities that have developed successful initiatives. The research has brought to light significant disparities, such as varying perceptions regarding the potential outcomes of climate change and its associated extreme events in African countries. In addition, the study highlighted areas where there is a notable consensus on specific issues. It also offers a comprehensive view of the different strategies that universities are implementing to contribute to climate change mitigation and adaptation in several areas. Although there is a growing interest in the need to contribute to the joint task of mitigating the effects of climate change and adapting to its consequences, HEIs need to increase their efforts to enhance the work of their professors and researchers. To this end, the involvement of public authorities and other private sector actors is essential.

Conclusions

This article outlines some actions that need to be undertaken so that universities may play a more active role in global efforts to handle the problems associated with a changing climate. There is a notable focus from academic actors on addressing climate change challenges in Africa. In addition, there is a proactive emphasis on utilizing science and research to comprehend climate change issues and offer widely applicable tools for adaptation and mitigation to safeguard both people and the environment. Consequently, it is crucial and time-sensitive for African universities to enhance their expertise in the field of climate change, fostering the capacity to conduct innovative research that addresses the various challenges linked to the evolving climate. This study offers several useful lessons for African universities to replicate experiences that have generated results in different countries and contexts.

Non-native species monitoring faces global challenges due to resource disparities, hindering effective implementation. Current strategies are fragmented and resource-dependent, inadequately addressing non-native species dynamics and are subjected to reporting biases, being further ridiculed by political borders. To overcome these challenges, a paradigm shift towards targeted, large-scale monitoring is crucial, requiring standardized protocols and advanced technologies like environmental DNA analysis, orchestrated, applied—and enforced—following international collaboration. Despite existing efforts, networks, and laws, even larger political entities like the European Union suffer from the lack of information exchange as well as economic, political, and socio-cultural differences among member status, ultimately hampering united efforts against the threat posed by non-native species. The absence of a comprehensive central hub and authority, guided by scientific input and at the same time empowered by being a political institution, emerges as a compelling solution. Despite potential drawbacks, this institution, possibly bridging gaps in the large-scale approach, could coordinate efforts, standardize reporting, allocate resources, and advocate increased funding. Considering rising introduction rates and accelerating impacts from non-native species, creating a centralized institution becomes imperative for enhancing global non-native species monitoring and management to foster a collaborative response to non-native species threats.

由于资源差异,非本地物种监测面临全球性挑战,阻碍了有效实施。目前的战略支离破碎,依赖资源,不能充分应对非本地物种的动态变化,而且受到报告偏见的影响,更受到政治边界的嘲弄。要克服这些挑战,必须转变模式,进行有针对性的大规模监测,这需要标准化的协议和先进的技术(如环境 DNA 分析),并在国际合作下协调、应用和执行。尽管已有努力、网络和法律,但即使是像欧盟这样的大型政治实体,也因缺乏信息交流以及成员国之间的经济、政治和社会文化差异而受到影响,最终阻碍了应对非本地物种威胁的联合努力。缺乏一个以科学意见为指导,同时又因其政治体制而获得权力的综合性中央枢纽和权威机构,是一个令人信服的解决方案。尽管存在潜在的缺陷,但这一机构有可能弥补大规模方法中的不足,可以协调工作、规范报告、分配资源并倡导增加资金。考虑到非本地物种引进率的不断上升和影响的加速,建立一个中央机构对于加强全球非本地物种的监测和管理,促进对非本地物种威胁的合作应对,变得势在必行。

Adopting a multi-criteria approach in forest management is essential for preserving or improving specific benefits while minimizing negative environmental impacts. Determining the appropriate long-term management approach for a forest requires considering heterogeneous environmental and social factors, as well as changes in forest characteristics over time. Conducting a strategic assessment of forest use suitability (FUS), namely productive, protective, conservation-oriented, social and multifunctional, at the national level, taking into account the dynamics in the provision of forest ecosystem services and the trade-offs between FUS alternatives, can guide the development of customized management strategies and policies that align with the specific requirements and conditions of the forest. In this study, we evaluate the supply and simulation-based changes over time of diverse ecosystem services of Pinus sylvestris stands in Spain and utilize a decision model to determine the most suitable FUS alternative that enhances the provision of these services. The assignment of the most appropriate FUS alternative aims to help in decision-making processes and in the selection of the most adequate management strategies. To achieve this, we utilize the last version of ecosystem management decision support (EMDS) system, a spatially focused decision support tool capable of generating precise results for multi-criteria assessment. Participatory planning actions based on Delphi principles and Analytic Hierarchy Process (AHP) analysis were applied and combined with geospatial logic-based modelling. According to the results, the dominant FUS is protective, followed by productive alternative, exhibiting high levels of multifunctionality.

在森林管理中采用多重标准方法对于保持或提高特定效益,同时最大限度地减少对环境的负面影响至关重要。确定适当的森林长期管理方法需要考虑各种环境和社会因素,以及森林特征随时间的变化。在国家层面对森林利用适宜性(FUS),即生产性、保护性、养护性、社会性和多功能性进行战略评估,同时考虑森林生态系统服务的动态供应以及 FUS 备选方案之间的权衡,可以指导制定符合森林具体要求和条件的定制管理战略和政策。在本研究中,我们评估了西班牙西伯利亚红松林各种生态系统服务的供应情况和随时间推移的模拟变化,并利用决策模型来确定最合适的 FUS 替代方案,以提高这些服务的供应。确定最合适的 FUS 替代方案旨在帮助决策过程和选择最适当的管理策略。为此,我们利用了生态系统管理决策支持系统(EMDS)的最新版本,这是一种以空间为重点的决策支持工具,能够为多标准评估生成精确的结果。我们采用了基于德尔菲原则和层次分析法(AHP)分析的参与式规划行动,并将其与基于地理空间的逻辑建模相结合。结果表明,主要的 FUS 是保护性的,其次是生产性的,表现出较高的多功能性。

Background

This study aims to tackle the lack of freshwater ecotoxicological effect factors (EFs) crucial for determining freshwater ecotoxicity characterization factors (CFs) using the widely accepted scientific consensus USEtox model for ecotoxicity impact characterization. The objectives are: (1) to offer a collection of experimental EFs to support USEtox ecotoxicity characterization factor computations and (2) to contrast ecotoxicity data produced by various quantitative structure–activity relationship (QSAR) models against experimental data.

Results

Experimental ecotoxicity data were gathered from the REACH database and CompTox Version 2.1.1, which includes toxicity information from ToxValDB v9.4. QSAR-driven ecotoxicity data were extracted from ECOSAR v1.11 and T.E.S.T. v5.1.2. The experimental and estimated data underwent a harmonization process to ensure consistency. Subsequently, aquatic ecotoxicological EFs were determined. The merged REACH and CompTox databases list EFs for 11,295 substances, each identified by a unique CAS number. Among these, the USEtox database already catalogs 2426 substances with freshwater ecotoxicological EFs. This study expanded on that by calculating EFs for an additional 8869 substances. Using estimated data, EFs were determined for 6029 chemicals based on ECOSAR data and 6762 chemicals using TEST data.

Conclusions

This study calculated EFs for an additional 8869 substances, thereby broadening their inclusion in LCA evaluations. When integrated with the USEtox EFs database, this research encompasses 11,368 chemicals. The high correlation observed between experimental EFs and those in the USEtox database lends significant confidence to the calculations for chemicals not listed in USEtox. Conversely, the low correlation between estimated EFs and those in USEtox suggests limited confidence in calculations based on estimated data. Furthermore, the disparity in correlations between EFs calculated using ECOSAR and TEST indicates that different QSARs can yield varied results. This discrepancy underscores the need for caution when relying on estimated data. Given that EFs are contingent on data availability, it is imperative to periodically update EFs as new data emerges.

背景本研究旨在解决淡水生态毒理学效应因子(EFs)缺乏的问题,该效应因子对于利用广泛接受的科学共识 USEtox 生态毒性影响表征模型确定淡水生态毒性表征因子(CFs)至关重要。目标是(结果实验性生态毒性数据来自 REACH 数据库和 CompTox 2.1.1 版,其中包括来自 ToxValDB v9.4 的毒性信息。从 ECOSAR v1.11 和 T.E.S.T. v5.1.2 中提取了 QSAR 驱动的生态毒性数据。实验数据和估计数据经过统一处理,以确保一致性。随后,确定了水生生态毒理学 EFs。合并后的 REACH 和 CompTox 数据库列出了 11,295 种物质的 EFs,每种物质都有唯一的 CAS 编号。其中,USEtox 数据库已经为 2426 种物质编制了淡水生态毒理学 EFs 目录。本研究在此基础上进一步计算了另外 8869 种物质的 EF 值。通过估算数据,根据 ECOSAR 数据确定了 6029 种化学物质的 EF 值,根据 TEST 数据确定了 6762 种化学物质的 EF 值。与 USEtox EFs 数据库整合后,这项研究涵盖了 11,368 种化学品。实验得出的 EFs 与 USEtox 数据库中的 EFs 高度相关,这为 USEtox 数据库中未列出的化学物质的计算结果提供了极大的可信度。相反,估算的 EF 与 USEtox 数据库中的 EF 之间的相关性较低,这表明根据估算数据进行计算的可信度有限。此外,使用 ECOSAR 和 TEST 计算的 EFs 之间的相关性差异表明,不同的 QSAR 可能会产生不同的结果。这种差异突出表明,在依赖估计数据时需要谨慎。鉴于 EF 值取决于数据的可用性,因此必须随着新数据的出现定期更新 EF 值。
