Summary: This study proposed an improved multi-source AHF model to accurately estimate the spatiotemporal distribution of anthropogenic heat flux (AHF) using diverse data sources and small-scale samples. The results showed that multi-source datasets and sophisticated algorithms could effectively reduce estimation errors and improve the accuracy of AHF distribution. The study also found significant seasonal variations in building metabolic heat and marginal fluctuations in industrial and transportation heat.

Summary: Increasing salt production and use is causing freshwater salinization syndrome, affecting biophysical systems globally. Anthropogenic activities have accelerated salt fluxes, creating an anthropogenic salt cycle. Salt accumulates in rivers and watersheds, impacting freshwater supplies, food and energy production, air quality, human health, and infrastructure. It is important to reduce salinization before exceeding planetary boundaries.

Summary: The research focuses on the VOC emission characteristics of industries and motor vehicles in China, with an emphasis on the dominance of oxygenated VOCs (OVOCs) in various emission sources. It highlights the importance of controlling emissions of reactive species, such as aromatics and alkenes, and the need for attention to the contribution of diesel vehicle emissions to urban ozone pollution. Changes in VOC emission characteristics of industries in China due to production process upgrades, such as the use of water-based coatings, increase the uncertainty in source apportionment research parameters.

Summary: Measurements have shown that nighttime production of atmospheric nitrate radicals increased significantly in China from 2014 to 2019, while it decreased in the United States and the European Union. This indicates a growing contribution of nighttime atmospheric oxidation to air pollution in China. Understanding the trends and implications of nitrate radicals is crucial for developing effective pollution mitigation strategies and understanding the impact of nitrogen oxides on climate.

Summary: By constructing national parks to optimize ecological, production, and living space structures, ecological assets can be converted into values while maximizing protection of the natural environment. This can lead to economic, social, and ecological benefits. Anthropogenic pollution in the Three-River-Source National Park region showed relatively low environmental stress intensity with significant spatial differentiation. Urbanization, industrialization, agriculture, animal husbandry, tourism, and transportation activities all contributed to various forms of environmental stress, with the need for measures to reduce stress in important ecological areas.

Summary: This study investigates the source and characteristics of K-bentonites in South China during the Late Permian, suggesting that volcanic activities associated with the Paleo-Tethys Ocean convergence may have led to the formation of K-bentonites. The integration of zircon Hf isotope and trace element compositions indicates that the K-bentonites in South China may have multiple sources, with major volcanic eruptions occurring at the Ailaoshan-Sanjiang continental margins and potentially smaller eruptions at the East Kunlun or West Qinling continental margins.

Summary: This study focused on measuring gaseous HCl and HBr in urban Beijing during winter and early spring of 2019, identifying factors affecting their concentrations, such as atmospheric temperature, UVB, gaseous HNO3, and burning aerosols. The researchers found that gas-particle partitioning and reactions with OH radicals led to significant production of atomic Cl and Br during the day. On polluted days, the production rates of atomic Cl and Br were faster than on clean days, suggesting an important recycling pathway of halogen species in inland megacities.

Summary: Increasing surface ozone (O3) concentrations has become a major air pollution problem in urban regions worldwide. This study proposes a new approach (EKMA) to diagnose the ozone formation regime using easily accessible O3 and NO2 observation datasets. By mapping the monitored data on a modeling diagram, the ozone formation regime and historical evolution of precursors can be illustrated. The findings show that for most urban regions in China, the ozone formation is currently associated with a VOC-limited regime.

Summary: In a semi-rural area in South China, anthropogenic activities led to the production of abundant chloride, and high levels of NO3 and efficient N2O5 uptake by aerosols facilitated the production of ClNO2. ClNO2 plays a significant role in ozone formation, resulting in a peak ozone concentration increase of up to 20 ppbv (38.5%). Reducing chloride emissions can help alleviate the burden of reducing NOx and anthropogenic VOCs for ozone pollution mitigation.

Summary: Monocarboxylic acids were used to modulate the number of missing-linker defects in Hf-porphyrin MOFs (Hf-TCPP-X) and enhance their performance in removing norfloxacin from complex aqueous matrices. The missing-linker defects promoted the removal efficiency by facilitating photoinduced charge transfer and increasing the number of active sites. This study provides a promising route to improve the removal performance of contaminants in highly saline water through defect engineering.

Summary: Primary emissions of pollutants in China have decreased, but controlling secondary aerosol pollution remains a challenge. This study examined the characteristics of secondary nitrate and sulfate conversion in several cities and used interpretable attribution techniques to determine their contributions to PM2.5. The results showed a significant relationship between nitrogen oxidation rate and O-3 concentration, and higher humidity promoted sulfur oxidation. Jinan had more intense secondary conversion and pollution events were primarily caused by secondary formation and vehicle emissions. Machine learning and interpretable attribution techniques show potential for addressing environmental concerns.

Summary: The chemical speciation of mercury in clouds has a significant impact on its behavior in the atmosphere and deposition on the surface. The study found that changes in cloud water chemistry, such as increased pH values and high levels of bromide ions, have led to a shift in the speciation of dissolved mercury. This shift may result in a decreased lifetime of atmospheric mercury and increased ecological risks associated with wet deposition.

Summary: Traditional photocatalytic oxidation of NO can cause the generation of more toxic NO2, while photocatalytic reduction of NO into N-2 is still challenging. In this study, a novel S-scheme beta-Bi2O3/Bi/g-C3N4 heterojunction photocatalyst is developed, which exhibits a higher degradation rate for NO (88.7%) with little NO2 generation compared to pristine g-C3N4 (60%). The enhanced degradation efficiency and efficient reduction pathway are attributed to the enhanced generation, separation, and transfer of photogenerated carriers through the Bi-bridge S-scheme heterojunction.

Summary: A Sv-ZnIn2S4-8/g-C3N4 (Sv-ZIS/CN) composite decorated with sulfur vacancies (Sv) was designed and fabricated for HCHO elimination. The in-situ growth of ZnIn2S4 (ZIS) on g-C3N4 (CN) led to the construction of heterojunction interface and generation of S-vacancies. The photocatalytic HCHO oxidation in the Sv-ZIS/5CN sample is kinetically favorable in the presence of abundant hydroxyl radicals (•OH) engaged in the successive C-H bond scission route.

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.

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.

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.
