Summary: The popularity of facemasks has increased in northern China due to severe air pollution. While wearing facemasks can reduce exposure to particulate matter, the protection is limited as people spend most of their time indoors. Installing indoor air purifiers is a more effective strategy for long-term protection against particulate matter exposure.

Summary: Air pollution levels in the United States have decreased, but racial-ethnic exposure disparities persist. Targeting specific locations for emission reductions can eliminate national exposure inequalities, while existing regulatory strategies require significant reductions. Additionally, location-specific strategies are found to be the most effective in reducing overall exposure and national inequalities.

Summary: This study identified an association between prenatal exposure to PM2.5 and placental gene expression, particularly in the first half of pregnancy. Offspring sex may also play a role in modulating this association, with a positive correlation observed in males and a negative correlation in females.

Summary: This study demonstrates the efficacy of roadside green infrastructure (GI) in improving local air quality by capturing and reducing airborne particulate matter (PM). A recently installed 'tredge' was found to be effective in intercepting and depositing PM, resulting in significant reduction in exposure in a school playground setting. The findings suggest that GI can be a cost-effective mitigation strategy.

Summary: The study found that a significant proportion of the population in Latin American cities live in areas with air pollution levels above WHO standards. Larger cities, higher GDP, higher motorization rate, and congestion tend to have higher PM2.5 levels. On the other hand, areas with higher population density tend to have lower levels of PM2.5.

Summary: This study proposes a new 3D approach for modeling indoor airborne particulate matter (PM) concentration using cellular automata (CA) framework. By considering four major PM transport mechanisms, the CA approach achieves high accuracy and efficiency in numerical simulations, making it a useful tool for 3D simulations of indoor PM transport and distribution.

Summary: This study found a modest association between prenatal exposure to PM2.5 and the risk of hypospadias, particularly within 1 month before pregnancy or the first trimester. There was no significant association observed between exposure to PM2.5-10 and PM10 during pregnancy and the risk of hypospadias in offspring.

Summary: Oxidative stress in cells is caused by an imbalance between oxidant production and the antioxidant system's ability to detoxify reactive products. This stress can lead to genotoxic damage, mutation, and play a role in carcinogenesis. Particulate matter (PM) air pollution has been identified as a cancer risk factor, and evidence suggests that PM-induced oxidative stress can contribute to various events promoting carcinogenesis. This review emphasizes the importance of studying the oxidative and genotoxic mechanisms associated with PM in malignant cell transformation and calls for more accurate approaches to assess its carcinogenic potential.

Summary: This study investigated the impact of short-term exposure to particulate matter (PM2.5) on work loss due to sickness. The findings showed a positive association between short-term ambient PM2.5 exposure and work loss, which was stronger among individuals with higher exposure to wildfire smoke. This suggests the need for further strengthening of PM2.5 standards in California to protect public health.

Summary: The study highlights the discrepancy between controlled emissions testing in laboratories and real-world emissions during normal use of cookstoves. Results indicate that the cookstoves may have a net cooling impact on the climate when considering factors such as nonrenewable biomass harvesting and various emissions, making them close to climate neutral in terms of primary PM2.5 emissions.

Summary: The composition of pyrolysis gases for wildland fuels is often determined using ground samples heated in non-oxidising environments. However, the applicability of this method to the wildland fire setting is unknown. This study compared the composition of pyrolytic and flaming combustion gases measured in wind tunnel fires and prescribed burns and found differences in gas composition between different fire phases and fire locations. The presence of live plants also significantly affected gas composition. A logistic regression model was able to classify samples based on gas composition with a high accuracy.

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 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.
