Summary: Biomass burning is a significant source of pollutants affecting climate, air quality, and public health. The emission factors of particulate matter and carbon monoxide were found to be highly sensitive to burning conditions, while nitric oxide showed a dependence on fuel type. A correlation between CO and PM emissions was observed, suggesting the potential for controlled burning experiments in tube furnaces to study biomass burning emissions.

Summary: The research found significant differences in recoverable energy and carbon monoxide emissions when burning two different fuels with different air supply parameters in the same device. The constantly changing position of the draft control door was found to have a negative impact on carbon monoxide emissions and energy production. By maintaining a constant draft door setting, optimal energy output and CO emissions levels for the two fuel types were determined.

Summary: A comprehensive emission inventory of the transport sector in Nepal was developed for the first time using fuel-based emission factors (EFs). The study estimated air pollutant emissions from diesel vehicles, compared diesel consumption by vehicle category with national sales data, and used Monte Carlo to estimate uncertainties. Tail pipe emission measurements were conducted using Ratnoze1 and Microaeth, and fuel-based EFs of CO2, CO, BC, and PM2.5 were calculated through the carbon mass balance method.

Summary: Household heating with wood stoves in rural areas of the US can lead to elevated indoor PM2.5 concentrations. Failure to clean chimneys and use of low-quality stoves can significantly increase PM2.5 levels. Regionally appropriate interventions such as upgrading to higher-quality stoves and regular chimney cleaning are essential for improving indoor air quality in rural wood-burning regions.

Summary: Household heating stoves are widely used in rural China during winter, contributing to a significant amount of particulate matter in the atmosphere. This study investigates user behaviors of household stove usage through surveys in Shanxi province. The results show that most users use their stoves for both cooking and heating, and a majority of households keep the stoves smoldering at night. Stove type, permanent population, and annual income are found to be potential influencing factors of user behavior. The results have implications for understanding emission fluctuations and designing heating appliances for practical use.

Summary: This study aims to improve air quality and meet WHO guidelines. The research shows that achieving an 80% reduction in emissions within a limited timeframe is unlikely in most areas of the Po Valley region. To achieve the goal, simultaneous reductions in activity levels, such as vehicle miles traveled, energy consumption, and industrial, agricultural, and livestock production, are necessary.

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.

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.
