Tracking semi-volatile organic pollutants in remote lake systems

Creator:: Usenko, Sascha
Abstract:: SOCs volatility and persistence properties cause many SOCs to become ubiquitous in the environment as well as accumulate in areas with lower temperatures such as polar or orographic regions. Many anthropogenic SOCs pose a serious risk to human and ecosystem health because of their persistent, bioaccumulative, and toxic properties in...

Numerical Simulation, Laboratory and Field Experiments, Analysis and Design of Wave Energy Converter and Mooring System

Creator:: Lou, Junhui
Abstract:: This dissertation studies the coupled fluid-structure interaction (FSI) of a wave energy converter (WEC) and evaluates the design of a WEC mooring system. The research is conducted in support of conceptual development, field test and performance evaluation of WECs as part of the mission of the Northwest National Marine Renewable...

Trans-Pacific and regional atmospheric transport of anthropogenic semivolatile organic compounds in the western U.S.

Creator:: Primbs, Toby
Abstract:: The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...

Development, validation and the application of a congener specific photodegradation model for PBDEs

Creator:: Zeng, Xia
Abstract:: The thermodynamic properties of 39 PBDEs have been calculated using Gaussian 03 on the B3LYP/6-31G(d)//B3LYP/6-31G(d) level. The PBDE congeners' enthalpies of formation increase with increasing number of bromines and show a strong dependence on the bromine substitution pattern. The effects of bromine substitution pattern have been quantitatively studied by GAM...

Local scale spatial and temporal variation in wet deposition of persistent organic pollutants by snow

Creator:: Walsh, Christopher D.
Abstract:: The objective of this research was to assess the variability of POP deposition by snow on a 10 km spatial scale by measuring the POP concentrations in fresh-fallen snow from remote alpine sites. Samples of pre-metamorphic snow were concurrently collected from three remote alpine sites, of matched altitude and exposure,...

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...

New Insights on the Southern Ocean Carbon Cycle from Biogeochemical Argo Floats

Creator:: Williams, Nancy L.
Abstract:: The Southern Ocean plays an important role in the ocean’s uptake of heat and carbon yet the processes controlling this uptake are not well understood. To date, more than 100 biogeochemical profiling floats that measure water column pH, oxygen, nitrate, fluorescence, and backscattering at 10-day intervals have been deployed throughout...

Prediction and Measurement of Polycyclic Aromatic Hydrocarbons (PAHs) Transformation Products in the Environment.

Creator:: Titaley, Ivan A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental contaminants consisting of fused benzene rings. Parent-PAHs, methylated-PAHs (MPAHs), and PAHs with molecular weight of 302 a.m.u (MW302-PAHs) are considered as unsubstituted-PAHs. These unsubstituted-PAHs undergo transformation reactions resulting in the formation of PAH-transformation products (PAH-TPs), or substituted-PAHs, including nitrated-, oxygenated-, and...

The atmospheric chemistry of particulate-bound polycyclic aromatic hydrocarbons : concentration, prediction, laboratory studies, and mutagenicity

Creator:: Jariyasopit, Narumol
Abstract:: The trans-Pacific atmospheric transport of particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) to remote sites in western North America has been well documented and has triggered research questions regarding to atmospheric transformation of PM-bound PAHs and the potential impacts on human health from their inhalation exposure. In this dissertation, field...

Synthesis, characterization, and analysis of nitroaromatic compounds

Creator:: McIntosh, Melissa Luana
Abstract:: Nitroaromatic compounds have important chemical applications and can be found in nature as pollution sources. Synthetic nitroaromatic compounds have been used in a variety of materials including explosives, pharmaceuticals, dyes, plastics, and pesticides. These compounds can find their way into the environment through normal or improper disposal methods. Poly-aromatic compounds...
