Cometabolism of Chlorinated Ethenes by Burkholderia vietnamiensis G4 Grown on Aromatic Substrates: Resting and Co-encapsulated Cell Kinetic Tests

Creator:: Saito, Alyssa M.
Abstract:: The cometabolic ability of Burkholderia vietnamiensis G4 grown on aromatic substrates was first assessed by resting suspended cells, and subsequently for cells encapsulated with and without slow release compounds (SRCs). In Chapter 3, benzyl alcohol was assessed as a food-grade growth substrate for promoting cometabolism of trichloroethene (TCE), via the...

From pesticide degradation products to legacy toxicants and emerging contaminants : novel analytical methods, approaches, and modeling

Creator:: Forsberg, Norman D.
Abstract:: Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...

Low Level Quantification of 1,4-Dioxane and Investigation of 1,4-Dioxane Co-Metabolism by Mycobacterium sp. 1A.

Creator:: McKeage, Kevin J.
Abstract:: 1,4-Dioxane (dioxane) is a probable human carcinogen and is often found comingled with chlorinated aliphatic hydrocarbon (CAH) contamination since dioxane is used as a stabilizer in CAH solutions. Dioxane is miscible in water, has a low K[subscript ow], low H[subscript cc], and is highly recalcitrant in the environment. The presence...

Analyzing the Relationship between Capillary Pressure, Saturation, and Interfacial Area for a Three-Phase Flow System in Porous Media

Creator:: Paustian, Rebecca L.
Abstract:: Multi-phase flow in porous media includes many instances of subsurface flow. Three-phase flow in particular is important in situations of enhanced oil recovery, CO2 sequestration, and groundwater remediation. Many studies have been performed on how two fluid phases (oil/water or air/water) behave in porous media, but very few studies exist...

Optimization of Geologic Carbon Sequestration: Effect of Flowrate on Nonwetting Phase Connectivity

Creator:: Davis, Brittany R.
Abstract:: Atmospheric carbon reduction is arguably the most crucial facet among efforts to mitigate climate change. The Fifth International Panel of Climate Change report emphasizes a worldwide goal of maintaining global temperature elevation less than 1.5°C above pre-industrial temperatures. This report also acknowledges without the proper utilization of counteractive emission strategies...

The Influence of Engineered Surface Coatings on Nanoparticle Aggregation and Corona Formation: Examinations in Simulated and Real Aquatic Media

Creator:: Surette, Mark C.
Abstract:: Engineered nanomaterials (ENMs) are small anthropogenic colloids with at least one length dimension <100 nanometers. Due to the nature of their use, ENMs are being increasingly released to the environment. Yet the environmental risks posed by ENMs are unknown due to a variety challenges, including limitations with detecting and quantifying...

The identification and quantitation of complex polycyclic aromatic hydrocarbon mixtures in environmental samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

Creator:: Manzano, Carlos A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...

Remediation of atrazine in irrigation runoff by a constructed wetland

Creator:: Runes, Heather B.
Abstract:: Due to its frequent use in agriculture and its frequent detection in surface water, atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...

Rheological Techniques in Characterization and Aiding in the Modification of Soft Matter

Creator:: Daalkhaijav, Uranbileg
Abstract:: Soft matter encapsulates a large array of materials ranging from electronics, plastics, and cosmetics to the biofluids making up all organisms. One of the most important properties of these materials that dictate their functionality is their rheology, which is the flow and deformation behavior in response to stress. The focus...
