Summary: Sub-Saharan Africa is experiencing rapid urbanization, with air pollution emerging as a major concern in growing cities, especially in Accra, Ghana. The study found that commercial, business, and industrial areas have the highest levels of PM2.5 pollution, with concentrations 2-4 times higher than WHO guidelines. Additionally, PM2.5 levels peak during the dry dusty Harmattan period, and have decreased by 50% compared to measurements in 2006-2007. Effective policies are needed to reduce pollution levels and protect public health in urban areas.

Summary: The study found that vehicle brake wear is the main source of airborne magnetite in the roadside environment in the UK, accounting for 68%-85%. In comparison, diesel and petrol engine emissions account for 7%-12% and 2%-4% respectively, while background dust contributes around 6%-10%. The high magnetite content in vehicle brake wear may pose potential risks to human cardiovascular and neurological health.

Summary: This study aimed to assess the risk of diabetes incidence associated with source-specific air pollution. The results showed that air pollution related to particulate matter (PM10, PM2.5) and traffic emissions was associated with an increased incidence of diabetes. These findings are consistent with the current evidence on traffic pollution as an environmental risk factor for diabetes.

Summary: This study measured nitrogen dioxide and black carbon concentrations inside London taxicabs and compared the air pollution exposures of diesel taxicab drivers and electric taxicab drivers. The findings indicated that diesel drivers had higher exposure levels, while the airtight cabin design and presence of in-built filter in electric taxis significantly reduced exposure to black carbon.

Summary: Inhaled particles and gases can harm health by promoting chronic inflammation in the body. This study investigated the relationship between outdoor air pollution and inflammation by race and ethnicity, socioeconomic status, and lifestyle risk factors. The results showed that particulate matter (PM) and other markers of traffic-related air pollution were associated with circulating levels of C-reactive protein (CRP), a biomarker of systemic inflammation.

Summary: The spatial and temporal evolution law of diesel particulate matter generated at different locations of the continuous mining face under the pressure-in ventilation condition was studied. The highest concentration of diesel particulate matter was found at the shuttle car discharge, reaching 144.17 mg/m³ and posing a serious health risk to miners. Limited space in the contact alley led to the accumulation of diesel particulate matter, forming a high concentration distribution area with a concentration value of 112.75 mg/m³. Different levels of pollution protection were obtained by using individual protective equipment based on the degree of DPM pollution in different areas.

Summary: Emerging evidence suggests that ambient particulate matter (PM) has negative effects on male fertility, especially the association between ambient PM2.5 exposure and semen quality. Long-term exposure during the past 70-90 days and 0-9 days, as well as throughout spermatogenesis, has significant effects on semen quality.

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.
