Summary: This study investigated the simultaneous effects of a specific noise barrier application on near-road noise and air pollution at a specific location. The results showed that the noise barrier not only reduced noise levels but also decreased the NOx concentration, improving air quality. The study also found that the dispersion mechanisms of NOx and noise were different, indicating the need for further research to optimize noise barrier designs considering both noise and air pollutants.

Summary: Fuel-based NOx emission inventories for California and the US over the period 1990-2020 showed a 70% decline in total on-road NOx emissions, with California leading the reduction by 48% compared to the national decrease. Further efforts have been taken in California to introduce new heavy-duty engines equipped with selective catalytic reduction systems, contributing to the steeper decrease in diesel NOx emissions in the state.

Summary: The study investigated the distribution patterns of traffic-related pollutants near a viaduct in Xi'an, China, and found that noise barriers and combination barriers have beneficial effects in mitigating air pollution near viaducts. The research revealed that the combination of different barrier types led to greater reductions in UFP, PM2.5, and BC concentrations compared to noise barriers alone.

Summary: This study investigates the influence of winter meteorology on exposure to traffic-related air pollutants (TRAP) near major roads. Results showed that the concentrations of TRAP were higher downwind compared to upwind, indicating the impact of traffic emissions. Even at 150 meters away from the highway, downwind concentrations were still elevated. Additionally, colder temperatures led to increased emissions of certain pollutants, further increasing the concentrations near roadways. Stagnant air conditions also contributed to higher concentrations of TRAP and related particulate matter. This study highlights the potential risks of elevated exposure to traffic emissions for individuals living near major roadways during cold and stagnant winter conditions.

Summary: This study conducted mobile measurements over a year to assess the concentration of LDSA, PM2.5, BC, and NO2 in central London. The results show that PM2.5 is not a reliable indicator of tailpipe emissions on major roadways, but higher concentrations of PM2.5 and NO2 are found in commercial neighborhoods with more restaurants. By isolating the impacts of traffic and restaurants, it is demonstrated that both sources have comparable effects on LDSA.

Summary: There is limited understanding regarding the health impacts of aircraft noise and aircraft-associated ultrafine particles (UFP). Measurements conducted near Gatwick airport in the UK showed a close relationship between particle number concentrations (PNC) and noise levels, with traffic emissions being the major source of PNC. However, UFP is unlikely to be a significant factor in epidemiological studies on aircraft noise and health, as the correlation between UFP and noise is moderate to low. Additionally, meteorological factors should be taken into consideration when studying the short-term associations between aircraft noise and health.

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.
