Summary: In this study, a back-propagation-neural-network-based ecologically extended input-output model (BPNN-EIOM) is developed to manage the virtual water metabolism network (VWMN). BPNN-EIOM can identify key consumption sectors, simulate VWMN performance, and predict water consumption. It is applied to analyzing Kazakhstan's VWMN and determining optimal management strategies under various scenarios. The findings provide useful insights for optimizing Kazakhstan's industrial structure, mitigating water scarcity, and promoting socio-economic sustainable development.

Summary: The cities of the Global South, particularly in Africa and Asia, are facing dual water security challenges — increased risk of water availability due to climate change and rising water demand due to economic and population growth. To effectively manage water resources, it is crucial to analyze the products imported from the global market and assess their water footprints. The study reveals significant and growing water imports through virtual water, with varying magnitudes based on cities' economic and geographical attributes. The findings emphasize the need for proactive water security strategies and leveraging the water-trade nexus.

Summary: This paper investigates the relationships of industrial waste discharge among different sectors in Jiangsu Province by constructing an industrial waste metabolic input-output (IWMIO) model. The results indicate that indirect discharge of industrial waste is greater than direct discharge in the industrial waste metabolism system. The tertiary industry, chemical industry, smelting and pressing of metals, and production and supply of electricity and heat dominate the industrial waste metabolism system. Certain sectors, such as mining and washing of coal, manufacture of non-metallic mineral products, and smelting and pressing of metals, have mutualism and competition relationships with other sectors, indicating the significance of controlling waste discharge in these sectors for achieving emission reduction targets.

Summary: Industrial Ecology Virtual Laboratories (IELabs) enable the construction of multi-regional input-output (MRIO) models from national to local scale, providing important support for analyzing research questions requiring sub-national spatial detail. The newly developed tool NLab allows nesting of sub-national MRIO tables within global country-scale MRIOs, facilitating the investigation of interactions between sub-national production and consumption systems. The results suggest that nested MRIO tables offer a more detailed regional level assessment for consumption-based footprint assessments, improving the quantification of regional impacts.

Summary: Urban water management is critical for China's goal of alleviating water stress and promoting water sustainability. This study estimated the city-level water footprints for 26 cities in the Yangtze River Delta and investigated the patterns and impact of virtual water trade. The results show that virtual water trade alleviates water shortage in the region, with richer cities importing more virtual water while less developed water-abundant cities exporting virtual water. The inter-city virtual water flows have also helped alleviate urban water scarcity inequality.

Summary: This study explored the impact of electricity trading on carbon emissions in China using various models and algorithms. The results showed that inter-provincial electricity imports offset carbon emissions, while exports increased carbon emissions. Additionally, the abundant hydropower resources in certain provinces reduced the impact of electricity exports on carbon emissions. Moreover, emission reductions were only observed when electricity trading was generated from renewable sources or if the exporting province had a lower carbon intensity than the importing province at the national level.

Summary: With the rapid development of China's urbanization and industrialization, industrial waste gas emissions have caused severe air pollution. A stepwise clustered industrial waste gas emission management model has been developed to support the formulation of mitigation policies. A case study in Chongqing Municipality shows that the emissions of sulfur dioxide are higher than those of fume and dust, indicating a greater focus on managing fume and dust emissions. Additionally, urban households in Chongqing contribute more to indirect industrial waste gas emissions compared to rural households.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
