Precombustion Removal of Hazardous Air Pollutant Precursors
The 1990 Clean Air Act Amendment (CAAA) contains provisions that will establish new emission standards for 190 potentially hazardous air pollutant precursors (HAPPs). Studies have suggested that many of these HAPPs have the potential to be removed prior to combustion. This thesis details the …

Novel mesoporous silicates as indoor air pollutant scavengers
… of volatile organic compounds (VOCs). The indoor air pollutants of interest were formaldehyde, toluene, ethylbenzene, o-xylene, cumene and dichlorobenzene. The indoor air pollutants were actively sampled onto (i) Tenax filled sampling tubes and subsequently analysed by thermal desorption gas …

An integrated assessment of air pollutant abatement opportunities in a computable general equilibrium framework
Air pollution and anthropogenic greenhouse gas emission reduction policies are desirable to reduce smog, tropospheric concentrations of ozone precursors, acid rain, and other adverse effects on human health, the environment, and the economy. While reduction of both air pollution and greenhouse gas …

Characterization of Urban Air Pollutant Emissions by Eddy Covariance using a Mobile Flux Laboratory
Air quality management strategies in the US are developed largely from estimates of emissions, some highly uncertain, rather than actual measurements. Improved knowledge based on measurements of real-world emissions is needed to increase the effectiveness of these strategies. Consequently, the …

Air Pollutant Concentrations and Trends over the Eastern U.S. and China: Aircraft Measurements and Numerical Simulations
… decades, efforts have been made to mitigate air pollution all around the world. With surface observations showing substantial decrease of criteria pollutants, including O3, NOx, CO and SO2, the long-term aircraft measurements over the eastern U.S. provide a unique opportunity to study the …

Life cycle air pollutant and carbon emissions from China’s road transport under vehicle electrification and renewable electricity expansion scenarios
… decades, becoming a major contributor to both air pollution and greenhouse gas emissions. As the country transitions toward carbon neutrality, vehicle electrification and renewable electricity (RE) expansion are central to national strategies for mitigating climate and environmental impacts. …

Understanding the Effect Of 1,3-Butadiene on Human Lung Fibroblasts: Does Exposure to 1,3-Butadiene Induce Senescence?
… of 1,3-butadiene, an important hazardous air pollutant and potent genotoxic agent found in cigarette smoke. In this study we examined the effect of DEB on the proliferative capacity of human lung cells. We hypothesized that exposure of human lung fibroblasts (HLF) to DEB induces …

Bayesian and geostatistical analysis of the effect of air pollution on asthma hospitalisation in Perth
… severe cases. Numerous studies have shown that air pollution is one of the factors that exacerbates asthma symptoms and while population increases in asthma hospitalisation have been shown for Perth, the nature of exposure and risk across areas within the metropolitan area have not been …

Early neighborhood disadvantage and risk for internalizing problems: underlying neurobiological mechanisms
… socioeconomic disadvantage and air pollutant exposure predict an increased risk for mental health difficulties across the lifespan. However, the neurobiological mechanisms underlying these associations remain unclear. In this study, I investigated the associations of early …

IL-10 Deficiency as a Factor in Airway Cellular Responses to Inhaled Sulfur Dioxide
Sulfur dioxide (SO2) is a problem air pollutant in areas of widespread industrialization, not only in the United States, but also in countries undergoing rapid industrialization, such as China. Thus, air pollution and its effects on the asthmatic condition have become a major focus in environmental …
