Summary: In this study, an emergy-based waterlogging footprint accounting framework was developed to comprehensively consider the economic and environmental factors. By using depth-damage functions, input-output analysis, and ecological footprint, the economic and environmental impacts of urban waterlogging in Beijing's old town were evaluated, and four indicators were established to quantify urban resilience. The results showed that the waterlogging footprints increased by 284.57% over 50 years, with the waterlogging footprints driven by environmental loss accounting for 13.02% of the total. The waterlogging footprint density and waterlogging resilience index displayed high spatial heterogeneity, indicating varying sensitivity of subdistricts to waterlogging.

Summary: China's air pollution policies prioritize differences between cities and emphasize coordinated control of pollutant emissions between cities, particularly in the context of supply chains. In examining the Beijing-Tianjin-Hebei urban agglomeration in China, it is found that nitrogen oxide (NOx) emissions are primarily concentrated in Tangshan and Beijing, with the electricity and heat, metal, and nonmetal sectors being the main suppliers in the NOx supply chains. The transfer pattern of NOx between cities in this region is generally efficient, extending from low- to high-emission intensity cities, while the pattern between cities in this region and other provinces is opposite. The results reveal the potential for emission reduction at the city level, with a focus on reducing the emission intensity of production-oriented cities in the Beijing-Tianjin-Hebei region.

Summary: This study focuses on the ecological management of urban agglomerations and explores the structural and functional differences between the city and urban agglomeration scales using a multi-level nested urban agglomeration network model. The results show that scale enlargement has limited influence on flow distribution, and the manufacturing -> environment path is the most important at both scales. The study also finds that with scale expansion, the environment sector and household consumption no longer have a prominent proportion, and mutualism emerges in energy conversion and environment. These findings provide a theoretical basis for material metabolism regulation and coordinated cleaner production and consumption in urban agglomerations.

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: As the consumption of Chinese medicine resources increases, the waste of traditional Chinese medicine extraction cannot be disposed of reasonably, which has a serious impact on the environment. Dissolved organic matter (DOM) in herbal extraction residue can bind to heavy metals (HMs), creating potential environmental risks. This study found that protein-like substances are dominant in the residual DOM of Chinese medicine extracts, becoming the main factor of water quality deterioration. The N-H groups in the protein-like materials prioritize binding with Cu(II). The study emphasizes the importance of continuous attention to the impact of herbal extraction residue on the geochemical behavior of HMs.

Summary: The identification of the drivers of carbon emissions is crucial for national-level carbon reductions. This study applies structural decomposition analysis (SDA) to 112 countries from 1990 to 2014 and finds that energy intensity is the most significant factor influencing total carbon emissions. Fuel mix and production structure show varying effects on different country groups. Additionally, increasing consumption volume poses a major obstacle to carbon dioxide mitigation, and population growth accelerates carbon emissions in developing countries.

Summary: This study investigated the antibiotic resistance of airborne bacteria during the COVID-19 pandemic by examining variations in the abundance of antibiotic resistance genes (ARGs), bacterial community structures, and risks to human health in four functional urban areas. The results showed a significant increase in ARG abundance during the COVID-19 period compared to before. Large-scale disinfection reduced overall bacterial abundance but promoted the survival of chlorine-resistant bacteria. Commercial areas had the highest diversity and abundance of aerosol bacteria. Antibiotic susceptibility assays demonstrated increased resistance among isolated bacteria due to disinfection exposure. The study highlighted the elevated antibiotic resistance of bacteria in aerosols exposed to disinfectants during the COVID-19 pandemic and provided guidance for the rational use of disinfectants and control of antimicrobial resistance.
