Summary: In recent years, PM2.5 has become a critical factor in causing severe air pollution. This study used data from central Taiwan and applied data analysis methods to investigate the correlation between PM2.5 and other air pollutants. The results showed that PM2.5 has the most consistent correlation with other pollutants, with carbon monoxide being the primary source pollutant. The study also found that the correlation between PM2.5 and ozone is lower, and the correlation between PM2.5 and other pollutants varies at different locations.

Summary: This paper analyzed the impact of AOD derived from Himawari-8 in PM2.5 predictions and proposed a novel hybrid model. The results showed that AOD missing rate is the highest in Nanjing, Hefei, and Maanshan, and the lowest in winter and summer. Considering AOD as an auxiliary variable in the model did not improve the accuracy of PM2.5 predictions and sometimes even slightly decreased it. Compared with other models, the proposed hybrid model demonstrated higher prediction accuracy.

Summary: This study investigates the causal links between a high-PM2.5 episode in Korea and air pollutants originating from China. The findings show that transboundary air pollutants from China significantly affect the PM2.5 concentration in Korea, especially in the Seoul Metropolitan Area. Certain meteorological conditions, such as westerly winds, high pressure in China, low pressure in Korea, high temperature, and stagnant air flow, can intensify the effect of long-range transboundary transport from China.

Summary: This paper discusses the disproportionate levels of fine particulate matter (PM2.5) air pollution experienced by communities of color and lower income in the US. The study finds that high-resolution PM2.5 datasets are consistent with the 12 km dataset in terms of national and regional averages, but differ in intraurban disparities. The datasets consistently indicate higher regional average PM2.5 concentrations in the least White and most Hispanic census tracts. However, in the ten most populous cities, the datasets differ in the order of least-to-most exposed population subgroups. The 12 km dataset fails to capture intraurban disparities and may mischaracterize disproportionately exposed neighborhoods.

Summary: Air pollution is a significant global environmental challenge, and India is heavily affected by it. Various sources such as automobiles, industries, household and commercial fuel burning, and dust from construction activities contribute to air pollution. The implementation of lockdown measures in India significantly reduced air pollutants. In this study, a hybrid model combining Daubechies discrete wavelet decomposition (Db-DWD) and autoregressive integrated moving average (ARIMA) was proposed to model and forecast air quality index (PM2.5) data for the most polluted cities in India (Agra, New Delhi, and Varanasi) before and during the lockdown period. The hybrid model improved forecasting accuracy and reduced errors.

Summary: Clean heating is seen as a key strategy to tackle air pollution in northern China. To address the differences in heating habits and residents' income between urban and rural areas, a cost-benefit analysis model is used to propose an improved solution that integrates multiple heat sources. By utilizing low-cost and low-emission-intensity ISM resources, the improved solution reduces PM2.5 emissions from heating to one-fifth, and achieves higher net social benefits.

Summary: The study introduces a near real-time air pollutant database named Tracking Air Pollution in China (TAP), which combines ground observations, satellite AOD, and other data sources to provide daily 10 km resolution PM2.5 data. The database utilizes a two-stage machine learning model to estimate PM2.5 concentrations, improving performance at high pollution levels and filling gaps in AOD data. The availability of daily PM2.5 data for tracking changes over time and long-term records since 2000 will support policy assessments and health impact studies.

Summary: Limitations in current PM2.5 monitoring affect air quality management and health risk assessment. Ground-based monitoring networks provide data in highly populated regions, but gaps exist in spatial coverage. Satellite-derived aerosol optical properties can complement ground-based monitoring, but are hindered by cloudy/hazy conditions or nighttime. In this study, a deep spatiotemporal neural network (ST-NN) is introduced to overcome these limitations and provide high-resolution and complete coverage of PM2.5 concentrations. Validation shows accurate results, and better spatiotemporal distributions will improve health studies and air quality predictions.

Summary: The study found that in settings of household solid fuel use, individual variability in exposure to air pollution is mainly dominated by differences within participants. Outdoor PM2.5 is the main variable affecting within-participant exposure, while household fuel use and smoking status explain between-participant variability. This suggests that reductions in air pollution exposure require simultaneous efforts to reduce both outdoor and indoor sources.

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.
