Analysis of Organochlorine Pesticides (OCPs) in Gray Whale Scat as an Alternative Method of Toxicant Quantification in Cetaceans

Creator:: Kutnerian, Amy M.
Abstract:: A method was developed to quantify organochlorine pesticides in whale scat. This method would ideally replace analysis of pesticides in blood and tissue samples, which are difficult to acquire. Scat samples were collected from one stranded gray whale and three live whales. The samples were extracted with pressurized liquid extraction,...

Analysis of semi-volatile organic compounds in high elevation lake sediments

Creator:: Wang, Yunzhu
Abstract:: The transport and deposition of airborne contaminants, including semivolatile organic compounds (SOCs), to high elevation ecosystems is recognized as a potential threat to these ecosystems. The objectives of this research were to develop an analytical method to measure a wide range of SOCs in high elevation lake sediment and to...

Aroma investigation of ‘Marion’ and thornless blackberries in Pacific Northwest of America

Creator:: Du, Xiaofen
Abstract:: The objectives of this study are to 1) qualitatively and quantitatively measure the odor-active compounds in ‘Marion’ blackberry; 2) compare the aroma profiles of advanced selections and new cultivars of thornless blackberry cultivars with ‘Marion’; 3) study the development of furaneol in ‘Marion’ during ripening and; 4) investigate the distribution...

Assessing the role of reactive metal species in soil organic matter cycling using chemical imaging

Creator:: Keiluweit, Marco
Abstract:: Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...

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...

Brown Marmorated Stink Bug (BMSB), Halyomorpha halys Taint in Wine : Impact on Wine Sensory, Effect of Wine-processing and Management Techniques

Creator:: Mohekar, Pallavi
Abstract:: Brown marmorated stink bug (BMSB), (Halyomorpha halys, Hemiptera: Pentatomidae) is an invasive species that damages numerous agricultural crops including grapes. Related damage include lower berry weight with increased exposure and cracked berries as a result of BMSB feeding activity. The insect is currently detected in 43 US states including Oregon,...

Copper Speciation in Wastewater-Impacted Surface Waters

Creator:: Mosbrucker, Ariel M.
Abstract:: This study investigates the relationship between total and ionic copper in samples taken from the Tualatin River and wastewater treatment facilities (WWTFs) that discharge into the Tualatin River. Copper speciation was analyzed by determining conditional stability constants and densities of copper binding ligands on the dissolved organic matter (DOM) in...

Decoding DOM Degradation with Metatranscriptomics : How Do Sunlight and Microbial Communities Interact to Degrade Dissolved Organic Matter in Arctic Freshwaters?

Creator:: Nalven, Sarah G.
Abstract:: Arctic soils are warming, making vast stores of organic carbon available for conversion to CO₂. This could create a positive feedback loop and accelerate global warming, but the processes that convert this carbon into CO₂ are not well understood. We investigated how the combined activities of sunlight and microbes degrade...

Development of volatile compounds in Pinot noir grapes and their contributions to wine aroma

Creator:: Fang, Yu
Abstract:: It is often perceived that late maturity of grape gives a more complex aroma profile to Pinot noir wine, however, there is little understanding of the basic flavor chemistry of grape maturity on wine aroma. The aroma contributing compounds in Pinot noir were first identified by aroma extract dilution analysis...

Dynamics of organic matter production and degradation during coastal diatom blooms

Creator:: Wetz, Michael S.
Abstract:: Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...
