Summary: Despite claims of safety or harm reduction for electronic cigarettes, emerging evidence shows that they are not likely safer than traditional cigarettes when it comes to the development of vascular dysfunction/disease. In a study using mice, the researchers found that the vasoconstriction response in skeletal muscle was similar between mice exposed to e-cigarette aerosol and cigarette smoke. This suggests that vaping is not likely to be safer than smoking in terms of vascular health outcomes.

Summary: Flavour preference is negatively associated with intention to continue vaping if a flavour ban occurred. Vaping for smoking cessation is positively associated with intention to purchase/use e-liquids and continue vaping if a flavour ban occurred. E-cigarette dependence mediates these effects.

Summary: The study evaluated the influence of different puff profiles on aerosol particle size distribution in pod-style electronic cigarettes, showing that most particles tend to deposit in the lungs, posing a potential risk of secondhand exposure. Further research is needed to understand the impact of other modifiable factors on particle size distribution and exposure potential.

Summary: The outbreak of e-cigarette or vaping-associated acute lung injury cases in 2019 brought attention to vaping, which involves inhaling heated aerosols containing nicotine or tetrahydrocannabinol. While physicians often associate vaping with e-cigarette devices, the use of alternative methods such as dabbing and dripping for aerosol inhalation is increasingly common. The health impact of these alternative methods remains poorly understood and may go unrecognized due to lack of familiarity among clinicians.

Summary: Stealth vaping, or discreetly vaping in places where it is prohibited, is common among college students, despite tobacco-free campus policies. In this study, a significant proportion of e-cigarette users reported previously engaging in stealth vaping on-campus. To effectively reduce on-campus e-cigarette use, enhanced monitoring and enforcement are needed, as well as further research to understand the factors influencing stealth vaping behaviors and their public health implications.

Summary: The socio-economic restriction measures implemented in the United States have significantly reduced nitrogen dioxide (NO2) emissions. The study highlights the impact of factors such as human mobility, population density, income, climate, and stationary sources on the reduction of NO2 at different stations. The research emphasizes the scientific impacts of the NO2 reduction and income inequality revealed by the pandemic on air quality and health disparities.

Summary: Unconventional oil and natural gas development (UOGD) in the United States has expanded rapidly in recent decades, raising concerns about its impact on air quality. This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud. The findings suggest opportunities to mitigate emissions during UOGD operations.

Summary: This study developed field emission factors for various pollutants in peatland fires and estimated the total emissions. Gas samples were collected using an analyzer, while particulate samples were collected using air samplers. The study found significant emissions of CO2, CO, PM2.5, carbon aerosols, water-soluble ions, and elements from the fires in Central Kalimantan, Indonesia in 2019.

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.

Summary: Accurate measurement of atmospheric reactive mercury is challenging due to its reactivity and low concentrations. The University of Nevada, Reno Reactive Mercury Active System (RMAS) has been shown to be more accurate than the industry standard, but has limitations including long time resolution and sampling biases. Increasing the sampling flow rate negatively affected RM concentrations, but did not impact the chemical composition of RM captured on membranes.

Summary: This study estimated the daily exposure concentrations of PM2.5 for elderly individuals residing in different regions of Taiwan using land use regression with machine learning (LUR_ML) and microenvironmental exposure (ME) models. The accuracy of the models varied across regions, with the ME models exhibiting higher predictions and lower biases. The use of region-specific microenvironmental measurements in the ME model showed potential for accurate prediction of personal PM2.5 exposure.

Summary: This study developed a sensitive method to measure the metallic components of atmospheric fine particulate matter (PM2.5) and compared the results with different analysis methods. The concentrations of metallic components in personal PM2.5 samples were found to be significantly different from corresponding fixed-site samples. Personal sampling can reduce exposure misclassifications, and measuring metallic components is useful for exploring health risks and identifying sources of PM2.5.

Summary: Increasing concentrations of microplastics in the Earth's atmosphere could have adverse effects on ecosystems and human health. The deposition rate of airborne microplastics is influenced by both land use and climate, and a global analysis suggests that climate may have a greater impact on the concentration and deposition rate of microplastics than land use.
