Summary: Sichuan province in China has been suffering from deteriorated air quality due to the growth of economy and vehicles, prompting government agencies to formulate various control measures. SO2 emissions decreased rapidly, while NOX emissions slightly increased. PM10 and PM2.5 emissions decreased consistently. Industrial processes contributed more to SO2 emissions, while road mobile sources were the largest contributor for NOX. Dust emissions were key sources for PM10 and PM2.5, and their contribution kept increasing. Comparisons with other inventories, satellite data, and ground observations indicated the credibility of the emission trends developed in this research.

Summary: Heavy port transportation networks are increasingly recognized as major contributors to PM2.5 pollution compared to vessels. The study reveals that non-exhaust emissions from port traffic play a significant role. By using filter sampling and the ER-PMF method, PM2.5 concentrations in different locations and traffic fleet characteristics were linked in the port area. The study shows that freight delivery activity emissions, including vehicle exhaust, non-exhaust particles, and road dust resuspension, accounted for nearly half of the total contribution. The contribution of non-exhaust emissions, especially from dense traffic with a high proportion of trucks, was comparable to exhaust emissions.

Summary: Meteorological changes and emission control have significant impacts on PM2.5 concentration and regional transport contribution. This study used the WRF-CAMx model to analyze the decomposition of meteorological conditions, emission, and regional transport in the Beijing-Tianjin-Hebei and Yangtze River Delta regions. The results showed that local contributions were the primary factor in PM2.5 concentrations, reaching 57.9% and 58.1% in 2017 for the respective regions. Regional transports were mainly from the Shandong Peninsula and Fen Nutrient Plain for Beijing-Tianjin-Hebei, while the Central Triangle Region and Shandong Peninsula for Yangtze River Delta.

Summary: Air pollution control policies in China have undergone significant changes, shifting from overall pollutant emission control to air quality improvement. The targets have changed from acid rain and NOx emissions to PM2.5 pollution and O-3 challenges. China has achieved remarkable success in reducing SO2 emissions and improving PM2.5 concentration, but stricter requirements for air quality and synergistic mitigation with Greenhouse Gas emissions have been proposed. Therefore, an integrated multi-objective and multi-benefit roadmap is needed to support China's long-term air quality improvement strategy.

Summary: The study found that PM2.5 from landscape fires had a stronger association with ARI among children under 5 years compared to PM2.5 from non-fire sources. Each 1 μg/m³ increment of fire-sourced PM2.5 was associated with a 3.2% increase in the risk of ARI. The proportion of fire-sourced particles significantly mediated the association between total PM2.5 concentration and ARI.

Summary: Nitrogen dioxide (NO2) exposure in China has led to a significant burden of premature deaths, especially in urban areas. This environmental inequality is evident as a small high-risk subgroup bears the majority of the NO2-related health impacts. Although there has been a reduction in the overall health impact of NO2 exposure from 2013 to 2020, inequality has slightly increased.

Summary: Chinese boilers account for 60% of primary energy consumption, emitting more air pollutants and CO2 than any other infrastructures. Through the integration of multiple data sources and various technical means, we established a nationwide facility-level emission dataset of over 185,000 active boilers in China, significantly improving emission uncertainties and spatial allocations. It was found that coal-fired power plant boilers emitted the highest CO2, while biomass- and municipal waste-fired combustion, considered zero-carbon technologies, emitted a large fraction of SO2, NOx, and PM.

Summary: Through studying the contributions of 155 emission sources to PM2.5-related mortality in China in 2017, we identified 25 priority-control emission sources and quantified the interprovincial ecological compensation volumes to alleviate inequality induced by emission allocation strategies. The results showed that PM2.5 pollution caused 899,443 excess deaths and around 127 billion USD costs in 2017. This study provides scientific evidence for optimizing emission allocation and compensation strategies in China and has wide implications for other countries suffering similar problems.

Summary: Clean vehicle policies will greatly benefit air quality and climate change mitigation. The study finds that due to these policies, national vehicle CO2 emissions in China will likely peak around 2028 and then decrease by 7.8% from 2028 to 2035. Most regions will experience a decrease in air pollutants emissions, leading to significant reductions in PM2.5 and O3 exposure. Approximately 68,000 PM2.5-related deaths and 33,000 O3-related deaths will be avoided nationwide from 2019 to 2035.

Summary: Product trade plays a crucial role in redistributing production and associated air pollution impacts among different sectors and regions. However, there is a lack of a comprehensive understanding of how air pollution is redistributed through trade chains, which hampers targeted clean air cooperation. In this study, we used multiple models to track the premature deaths related to PM2.5 along supply chains in China. Our findings reveal the key sectors and regions that contribute to PM2.5-related mortality from both a production and consumption perspective, and emphasize the importance of cross-boundary effects and capital investment in driving air pollution transfer.

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.

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.
