Summary: This study investigates the seasonal characteristics, formation, and sources of PM2.5 in Suzhou, Yangtze River Delta, China in 2020. Organic matter is found to be the dominant component of PM2.5, with the highest average value in spring. In summer, PM2.5 is mainly produced by the oxidation of volatile organic compounds.

Summary: The study found a strong positive correlation between AOC and O-3, while the correlation with PM2.5 was weaker. The concentration of precursors in winter may drive secondary aerosol formation, with aqueous or heterogeneous reactions likely playing an important role in high aerosol loadings in the YRD region.

Summary: This study found that most haze events in the Yangtze River Delta in autumn and winter were associated with cold frontal passages. During cold front episodes, the transport of PM2.5 mass from the North China Plain was 10-15 times higher compared to noncold front periods. Both unmanned aerial vehicle sounding and model simulation indicated a stronger and faster upper-level transport of PM2.5 than at ground level during cold front passage.

Summary: In this study, an obliquely rotated principal component analysis in the T-model is applied to classify the synoptic patterns of winter weather over the YRD region from 2013 to 2018. A transport pollution index (TPI) is constructed to describe the transport features of PM2.5 pollution over the YRD region, and when considering both the TPI and SWI (TPIthornSWI), the correlation coefficients increase significantly to better reflect the wintertime PM2.5 pollution level over the YRD region.

Summary: Since 2013, the implementation of pollution prevention and control action in China has reduced particulate pollution but increased ozone pollution, especially in the economically developed eastern region. Based on long-term observation data, the spatio-temporal characteristics of urban PM2.5 and O-3 pollution in the Yangtze River Delta were analyzed, and the effects of meteorological and non-meteorological factors on pollution were quantified. The results provide insights into particulate and ozone pollution in the region and can assist policymakers in formulating accurate air pollution prevention and control strategies at urban and city cluster scales in the future.

Summary: The study in the Yangtze River Delta region found that PM2.5-bound PAHs and NPAHs significantly increased during haze pollution days, with major sources of pollution including traffic emissions and coal combustion. The enhancement of atmospheric oxidation capacity contributed to the secondary formation of NPAHs, resulting in significant health risks associated with PM2.5-bound PAHs and NPAHs.

Summary: China has been facing serious and frequent air pollution in recent years. The productivity of manufacturing companies is inhibited by air pollution, particularly during low temperatures. Research showed that air pollution significantly decreased the productivity of listed manufacturing companies in China's Yangtze River Delta urban cluster, with a 0.1% decrease for every 1% increase in PM2.5 concentration. High-energy-consumption and low-technology manufacturing industries were more sensitive to the negative effects of air pollution. Cold temperatures intensified the negative effects of air pollution, especially in the fall and winter seasons.

Summary: Establishing an efficient PM2.5 prediction model and understanding the drivers of PM2.5 concentration are crucial for addressing and mitigating PM2.5 pollution in the Yangtze River Delta. Through analysis, it was found that PM2.5 pollution in the region was concentrated in certain areas, with a stable trend over 17 years. Geographically Weighted Random Forest (GWRF) was identified as a superior model for predicting PM2.5 presence. Climate and human activities were identified as the most important drivers of PM2.5 concentration, with drought, temperature, and temperature difference being critical factors. Taking these factors into account can enhance PM2.5 prediction and inform policy-making.

Summary: This study investigates the pollution characteristics of secondary organic aerosols (SOA) in the urban agglomeration of the Yangtze River Delta region. The results show a high degree of regional consistency in the concentration of SOA tracers among the three central cities. The concentrations of isoprene and alpha/beta-pinene SOA tracers were significantly higher in summer, attributed to plant emissions, while the higher concentration of beta-caryophyllene SOA tracer in winter can be linked to biomass burning. The study also reveals the correlation between SOA tracers and sulfate, indicating that biogenic SOA formation is facilitated by high concentrations of sulfate.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

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: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

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: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

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.
