Summary: The study compared different retrieval settings for formaldehyde and sulfur dioxide under various weather conditions, finding that specific wavelength windows and polynomial orders led to significantly reduced fitting errors and improved accuracy of vertical column densities. Additionally, the observed vertical column densities of HCHO and SO2 were significantly lower on foggy days compared to clear days, indicating reduced chemical production of HCHO and aqueous phase oxidation of SO2 in fog droplets.

Summary: This study analyzes the influence of human activities on winter haze events in the Jing-Jin-Ji region, showing that changes in dynamical and thermal meteorological conditions contribute to the formation and accumulation of haze. Human activities have a greater impact on increasing haze days in the region compared to natural forcing, with dynamical factors playing a larger role than thermal factors.

Summary: This research assessed the spatio-temporal changes of haze pollution and its relationship with gaseous pollutants and meteorological conditions in Tehran metropolis for 1990-2020. The results showed a decreasing trend of haze pollution annually and in winter, along with an increasing trend in horizontal visibility. Wind speed was found to be the principal driver behind the decrease in haze pollution and the increase in visibility.

Summary: In this study, a 3x50-layer spatiotemporal deep learning (DL) model called deep Weather Index for Aerosols (deepWIA) is proposed to estimate daily variations in aerosol concentrations by linking synoptic variations in aerosol concentrations and meteorology. The model was trained and validated using 7 years of data and successfully reproduced the variation in daily PM2.5 observations in China. The index outperformed other simulation models and commonly used PM2.5 concentration retrieval models based on random forest (RF), extreme gradient boost (XGB), and multilayer perceptron (MLP).

Summary: The study by the authors focused on analyzing the contributions of meteorology and emissions to long-term trends in PM2.5 pollution from 2000 to 2018 in China. It was found that while emissions played a dominant role in the long-term trend of PM2.5 concentration, meteorological conditions also had a notable influence, particularly in affecting interannual variabilities in meteorology-associated PM2.5.

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: The study reveals that haze episodes with PM10 concentration exceeding standards frequently occur in Lamphun Province, northern Thailand, during the dry season from February to April. PM10 concentration is negatively correlated with relative humidity and temperature, and positively correlated with CO and NO2 concentrations. Furthermore, CO and PM10 concentrations are associated with ozone concentration.

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.
