Abstract:

Dust originating from dry lakes contributes harmful and toxic elements to downwind urban areas and mountain snowpack that is compounded by local contaminant inputs from anthropogenic sources. To evaluate dust contributions to an urban area from regional playas, we sampled playa dust sources, urban dust deposition, and snow dust deposition in central Utah, USA. Samples were analyzed for grain size, mineralogy, and chemistry. Bulk mineralogy between playa, urban, and snow dust samples was similar, with silicate, carbonate, and evaporite minerals. Grain size distribution between fine playa, urban

In China, the sediments of dust storms mainly come from the desert and thus are called "yellow-dust storms." Although these storms can disrupt socioeconomic activities widely and pose hazards to human health as well as to the ecosystem, no one has made a systematic socioeconom

Abstract:

The resuspension of road dust has been recognised as a source of airborne particulate matter, but little information exists as to the strength of this source or to the factors affecting it, particularly in relation .to the United Kingdom This study has focused on determining emission rates for wind-induced road dust resuspension from a tarmac surface for a range of wind speeds, including an unsteady 'gusty' flow. A wind tunnel has been used to generate a boundary-layer flow above a tarmac surface. The flow generated has been compared to that occurring close to a tarmac airport runway and the t

Abstract:

Since the UK industrial revolution, coal combustion, ore smelting and other industrial activities have resulted in a marked increase in emissions of potentially toxic elements (PTEs) such as antimony (Sb), lead (Pb), arsenic (As), copper (Cu) and zinc (Zn), along with polycyclic aromatic hydrocarbons (PAHs), to the atmosphere. Although stricter environmental regulation and improved technology has led to a notable decline for some contaminant emissions in recent decades, this has not been observed for all elements, e.g. Sb, where only a modest reduction in emissions have been recorded.

Doutoramento em Química<br>Urban soil quality may be severely affected by hydrophobic organic contaminants (HOCs), impairing environmental quality and human health. A comprehensive study was conducted in two contrasting Portuguese urban areas (Lisbon and Viseu) in order to assess the levels and potential risks of these contaminants, to identify sources and study their behaviour in soils. The concentrations of HOCs were related to the size of the city, with much higher contamination levels observed in Lisbon urban area. Source apportionment was performed by studying the HOCs profiles, t

Abstract:

Research on road safety has been of great interest to engineers and planners for decades. Regardless of modeling techniques, a serious factor of inaccuracy - in most past studies - has been data aggregation. Nowadays, most freeways are equipped with continuous surveillance systems making disaggregate traffic data readily available ; these have been used in few studies. In this context, the main objective of this dissertation is to capitalize highway traffic data collected on a real-time basis at the moment of accident occurrence in order to expand previous road safety work and to highlight pot

Abstract:

Little is currently known regarding the nature and consequences of interactions between photoactive surfaces, including mineral dust and ‘urban film’, and gas-phase pollutants in urban environments. In order to address this knowledge gap, this thesis explores the photochemical reactivity of these environmental surfaces in controlled laboratory settings. The photoenhanced ozonation of pyrene, a toxic product of incomplete combustion, proceeds at different rates and via different mechanisms at three model ‘urban film’ surfaces. These results are important because they suggest that the reactivity

Unlike earlier films of the 80s, which provide a strong sense of nostalgia of the Taiwan in the 60s and 70s, these urban films seem rather empty once the camera focus shifts to the city. This phenomenon calls for a reconsideration on the issue of nostalgia in Hou’s films. Nostalgia is one of the most renowned aesthetic features o

Lavada “Dr. Hepcat” Durst was the first African American popular music disc jockey in Texas. His radio program The Rosewood Ramble was broadcast on Austin station KVET-1300 AM from 1948 until 1963. KVET’s white owners, who included future Texas politicians John Connally and J. J. “Jake” Pickle, were not outspoken advocates for the rights of African Americans under Jim Crow, but they hired Durst in a concentrated effort to expand KVET’s African American listening audience. The Rosewood Ramble became a cultural, economic, and psychological resource for black radio listeners in segregated central
