Atmospheric trace elements and their application in tracing air pollution

Creator:: Shum, Yin-Sang
Abstract:: The atmospheric trace element abundances associated with several major sources of air pollution in Western Oregon, such as the paper industry, the metallurgical processing industry, the plywood industry and agricultural field burning have been measured by instrumental neutron activation analysis (INAA). Air samples were collected directly from industrial stacks and...

Comparison between lichen, conifer needles, resin-based passive air sampling devices (PASDs), and snow to monitor semi-volatile organic compounds (SOCs) in the atmosphere

Creator:: Schrlau, Jill E.
Abstract:: The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...

Relative influence of trans-Pacific and regional atmospheric transport of polycyclic aromatic hydrocarbons (PAHs) in the Pacific Northwest (PNW), USA

Creator:: Lafontaine, Scott
Abstract:: The relative influences of trans-Pacific and regional atmospheric transport on measured concentrations of polycyclic aromatic hydrocarbons (PAHs), PAH derivatives [Nitro- (NPAH) and Oxy-(OPAH)], organic carbon (OC), and Particulate Matter (PM) less than 2.5 μm in diameter (PM₂.₅) were investigated in the Pacific Northwest, USA in 2010-2011. Ambient high volume PM₂.₅...

Semi-volatile fluorinated organic compounds in Asian and Pacific Northwestern U.S. air masses

Creator:: Piekarz, Arkadiusz M.
Abstract:: Current studies suggest that perfluorinated organic compounds, such as fluorotelomer alcohols (FtOHs) in the troposphere, may be precursors of perfluorocarboxylic acids and perfluorosulfonates in remote regions. Fluorinated organic compounds were investigated in archived extracts collected from remote locations in Okinawa, Japan (HSO) and Mount Bachelor, Oregon (MBO) during the springs...

Optimization by transfer function estimation of the galvanovoltammetric determination of dissolved chlorine in a flowing stream

Creator:: Miller, Clinton Earl
Abstract:: Optimization of the galvanovoltammetric determination of dissolved chlorine in a flowing stream was achieved through the use of an analog computational device and improvements in the design of the galvanovoltammetric cell and accompanying electronic circuitry. An analysis system, applicable to industrial use over a range of flow rates and dissolved...

Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

Creator:: Chibwe, Leah
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

Measuring in situ biotransformation in BTEX-contaminated groundwater

Creator:: Alumbaugh, Robert E.
Abstract:: Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

Atmospheric transport of anthropogenic semi-volatile organic compounds to the Olympic Peninsula of Washington State

Creator:: Killin, Robert K.
Abstract:: Ambient high-volume (hi-vol) air samples were collected between March 15th and May 30th 2002, at Cheeka Peak Observatory (CPO), located on the tip of the Olympic Peninsula, Washington State. This sampling campaign was in conjunction with the 2002 Inter-Continental Transport and Chemical Transformation (ITCT 2K2) Campaign and the Photochemical Ozone...

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 of novel analytical methods to detect emerging contaminants in aqueous environmental matrices using large-volume injection

Creator:: Backe, Will J.
Abstract:: It is the responsibility of humans, as environmental stewards, to monitor our impact on the environment so that efforts can be made to remediate the effects of our actions and change behaviors. To better understand our environmental footprint, sensitive and simple analytical methods are needed to quantify the contaminants that...
