Summary: The study investigated the effects of partial lockdown measures on air quality in Bangkok, specifically focusing on PM2.5 and gas concentrations. While some pollutant concentrations were higher before the lockdown, the changes in PM2.5 levels during the lockdown were influenced by both local sources and external factors, such as transboundary aerosol transport from biomass burning. Reducing Bangkok's air pollution requires addressing various sources, including improving equipment for sugarcane harvesting to reduce biomass burning, implementing stricter emission control standards for diesel engines, and coordinating efforts among ASEAN member countries to address transboundary haze.

Summary: Air pollution in built-up areas of Asia, caused by rapid industrialization and urbanization, has become increasingly severe. This study focuses on examining the impact of pollution on the health of people living in Bangkok, Thailand. The major sources of air pollution in Bangkok are identified as local emission sources and sea salt. The health risks associated with particulate matter exposure are found to be mostly non-carcinogenic, except for chromium, which poses a carcinogenic risk to adults through inhalation. Overall, this research emphasizes the serious threat that air pollution poses to the residents of Bangkok.

Summary: Exposure to diesel PM2.5 via intratracheal instillation significantly altered the gut microbiota diversity and community in C57BL/6J mice, leading to a decrease in Bacteroidetes phylum and an increase in certain genera such as Escherichia, Parabacteroides, Akkermansia, and Oscillibacter. This study highlights the impact of diesel PM2.5 on gut microbiota structure and composition, potentially contributing to developmental abnormalities in inflammation, immunity, and metabolism.

Summary: This study monitored seasonal variations in ultrafine particulate matter (PM0.1) in Bangkok, Thailand and found that biomass burning in neighboring areas increases particle concentration. OC and EC carbon species, as well as OC/EC ratios, were observed to increase significantly in both wet and dry seasons, indicating that vehicle exhausts are the main influence on PM0.1 in the Bangkok atmosphere. The study also revealed that carbonaceous aerosols in Bangkok are light-absorbing and -scattering, with a greater contribution from secondary sources during the dry season, affecting climate and air quality. These findings are of great importance for air pollutant control policies in urban areas.

Summary: The study finds that ammonia emission reduction is an effective measure to mitigate wintertime PM2.5 pollution, but it is still necessary to prioritize the combined control of SO2 and NOx in Wuhan, China. However, when the ammonia control approaches its optimal effectiveness, the reduction measures targeting ammonia and NOx can greatly exceed the observed effects during the 2012-2018 period in Central China.

Summary: Widespread underground coal fires (UCFs) release large amounts of pollutants, including carbonaceous particles with various compositions such as heavy metals and polycyclic aromatic hydrocarbons (PAHs). Inhaling UCF PM2.5 can induce inflammation and oxidative stress in lungs, liver, and kidneys, leading to multiple organ injuries. Long-term exposure to PM2.5 may cause chronic diseases. It is important for local authorities to recognize the significance and impact of UCF emissions, especially PM2.5, and implement control and mitigation measures.

Summary: This study examines the effects of diesel-gas co-fuels, engine loads, and aftertreatment on emissions from a heavy-duty diesel engine. The results show that the gas fuels increase hydrocarbon emissions, decrease opacity, and increase emissions of both volatile and nonvolatile nanoparticles. Special attention should be given to the addition of H-2 under high load, as it causes significant increases in volatile nanoparticles. The nonvolatile nanoparticles can be effectively removed by the aftertreatment.

Summary: Local questionnaire surveys were conducted in the Red River Delta (RRD), Vietnam, to collect representative activity data for residential combustion emissions. The study found large differences in emissions between urban, suburban, rural areas, and deep rural areas due to cooking activities, fuel-stove types, and fuel consumption. Emissions increased over the 6-year period, with a dominant role of black carbon in the global warming potential results. Switching from solid fuels to liquefied petroleum gas was suggested to reduce emissions and bring multiple benefits.

Summary: The inability to effectively communicate how infectious diseases spread in human environments has led to avoidance of interactions during the COVID-19 pandemic. The authors introduce a metric, Effective ReBreathed Volume (ERBV), to quantify transmission and analyze the impact of different particle sizes and interventions on spreading. This framework helps in identifying transmission modes and effective interventions, supporting mitigation decisions in emerging situations.

Summary: Shifting from fossil fuels to renewable energy is crucial for limiting global temperature rise. However, the mining and smelting processes required for renewable energy technologies emit significant amounts of PM2.5 particles. The future PM2.5 emissions from mining and smelting to meet the metal demand of renewable energy technologies are estimated to contribute 10%-30% of total anthropogenic primary PM2.5 combustion emissions in many countries. The concentration of mineral reserves leads to regional impacts.

This study developed emissions inventories for 2015 and 2018 to assess the impact of fuel sulfur regulations in Ha Long Bay. The results show that reducing sulfur content in fuel for domestic vessels can significantly decrease SO2 and particulate emissions, while international vessels have a growing contribution to emissions. These findings can help inform emission reduction strategies and health impact assessments.

Summary: Household access to clean energy is essential for public health and environmental preservation in low- and middle-income countries. This study proposes a hierarchy of reduction potentials for household energy emissions, taking into account various implementation barriers such as distributional, technical, economic, and market factors. By applying this framework to India, the researchers found that implementing reduction programs within a certain distance from urban centers can achieve a significant portion of the theoretical reduction potential. Additionally, the study emphasizes the importance of considering the factors that affect transitions to clean energy solutions rather than solely quantifying baseline emissions in emission inventory development.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
