Summary: This study investigated the adsorption capabilities of acid-modified fly ash for escaped ammonia (NH3) and its impact on specific resistance. The results showed that acid activation improved the specific surface area and porosity of fly ash, leading to enhanced NH3 adsorption performance. Sulfuric acid-modified fly ash exhibited the highest adsorption capacity and maintained good specific resistance characteristics, indicating its potential application in flue gas treatment processes.

Summary: Manganese oxides and organic acids are important factors affecting arsenic mobility. Low concentrations of arsenic are generally inhibited from oxidation by organic acids. However, high concentrations of arsenic can lead to manganese dissolution, thereby facilitating arsenic oxidation and adsorption.

Summary: Process-based water system models have evolved from single-functional to integrated multi-objective and multi-functional models since the worldwide digital upgrade of urban water system management. However, the increasing complexity of these models leads to more uncertainties and computational requirements. In this study, a novel machine learning system called MLPS is introduced to expedite parameter optimization with limited data and improve efficiency in parameter search. The results demonstrate that MLPS enhances the performance and efficiency of the integrated model and enables the efficient optimization of integrated process-based models, thereby facilitating the application of highly precise complex models in environmental management.

Summary: This paper analyzes the transitions in the aviation industry in Sweden and examines the role of narratives as coordinating mechanisms in sustainability transitions. The study finds that industry actors construct narratives about alternative fuels and technologies to maintain the societal function of aviation while mitigating its climate impact. Narratives not only initiate transitions but also play a vital role in coordinating actors' transition activities.

Summary: Climate change poses a critical challenge to human well-being, particularly in terms of vulnerability and livelihood impact on communities. This study reveals the high vulnerability of communities in the western highlands of Tanzania to climate change and non-climate stress factors, including seasonal changes in rainfall and temperature, as well as the decrease in crop production and income.

Summary: Energy efficiency measures are crucial for combating climate change, but rebound effects may undermine their effectiveness. This study finds that prior energy efficiency behavior does not hinder subsequent climate-friendly behavior, which is determined by individual demographics and environmental attitudes.

Summary: Global climate change is expected to accelerate biological invasions. In this study, the researchers assessed the invasion risks of a highly invasive ascidian along Chinese coasts under climate change. They identified distinct genetic clusters and used different models to predict invasion risks. The results showed that the south cluster had higher invasion risks in the future.

Summary: Contaminants primarily reach the Arctic through long-range atmospheric and oceanic transport, with local sources also contributing to the environmental levels. The City of Iqaluit in Frobisher Bay, Nunavut, Canada has seen rapid population growth and development, and the region involves both local sources and long-range transport for ocean protection and country food harvesting, with a long legacy of persistent organic pollutants from past human activities.

Summary: With ASEAN's rapid population and economic growth, its medium-term climate ambition becomes crucial to global mitigation efforts. Although all ASEAN Member States have communicated their ambitions through NDCs, the region still falls short of a 1.5 or 2-degree scenario. Assessing and comparing the NDCs is complex due to varying types of targets and actions. Through an assessment framework, AMS' strategies for raising mitigation ambition are examined, with the need for stronger economy-wide targets identified. Different groups with varying stages of progress in climate ambition among AMS are clarified, along with specific recommendations for each group.

Summary: This study investigates the significant impact of large-scale land-sea atmosphere interaction (LSAI) on ozone (O3) pollution in the Bohai-Yellow Seas and adjacent areas. The results demonstrate the role of LSAIs in O3 formation and pollution duration, providing valuable insights for understanding and managing O3 pollution in coastal cities.

Summary: The performance of different maize-legume diversification strategies was compared in southern Africa. Intercropping systems showed significant nutritional and economic benefits, but had higher labor requirements compared to other cropping systems. Soil organic carbon content and pH were not affected by the tested cropping systems.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: Nitrification and denitrification are crucial for nitrogen losses in agricultural soils and are affected by soil properties. This study investigated the patterns and controlling factors of nitrification and denitrification potentials in paddy soils in major rice-producing areas of Hubei Province, China. The results showed that soil pH and SOC were the primary factors regulating nitrification and denitrification potentials, respectively.

Summary: This study investigated changes in vascular plant species in Central European arable fields and their edges from 1930 to 2019. The results showed a small decline in overall species occupancy, but a more pronounced species turnover. Species with environmental preferences for nutrient-rich sites with neutral pH increased in occupancy, while species typical for arable fields decreased. No response to climate change was observed, and there was a decrease in archaeophytes and native species and an increase in neophytes.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.
