Spatial and temporal variations of bioavailable polycyclic aromatic hydrocarbons in the lower Willamette River

Creator:: Sower, Gregory J.
Abstract:: Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and assessment of remediation efforts. To more effectively estimate human and ecological health risks, we evaluated the spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) in...

Development and application of a new passive sampling device : the lipid-free tube (LFT) sampler

Creator:: Quarles, Lucas W.
Abstract:: Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely...

Exploring Silicone Wristbands as Personal Passive Sampling Devices in a Disaster Scenario

Creator:: Samon, Samantha M.
Abstract:: Exposure assessment is necessary to determine the frequency and magnitude of environmental contaminants, especially since exposure may lead to adverse health outcomes. Traditional personal exposure assessment tools such as biological samples are limited in their ability to capture a wide range of chemical exposures from a single sample, and others...

New Applications for Passive Samplers : In-situ Flux and Risk Assessment of Legacy and Emerging Contaminants

Creator:: Tidwell, Lane G.
Abstract:: Passive sampling devices (PSDs) were used to measure air vapor and water dissolved phase concentrations of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) at two different environmentally contaminated sites. Environmental contaminates like PAHs and OPAHs are present in both the atmospheric and aqueous environmental compartments. It is known that...

Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

Creator:: Taft, Oriane Williams
Abstract:: Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...

Environmental complex mixtures modify benzo[a]pyrene and dibenzo[a,l]pyrene-induced carcinogenesis

Creator:: Courter, Lauren A.
Abstract:: Human exposure to the carcinogenic polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene (B[a]P) and dibenzo[a,l]pyrene (DB[a,l]P) is through environmental complex mixtures, such as urban dust particulate matter (UDPM) and diesel exhaust (DE), however the potency of these PAH within a mixture is not established. To determine the effect of these mixtures on...

Consequences of coumaphos and Varroa destructor on drone honey bee sperm quantity

Creator:: Delaney, Deborah Anne
Abstract:: The number of drones and genetic diversity among drones are essential components to a well mated queen. Varroa destructor preferentially parasitizes drone brood, and is thought to be responsible for the loss of feral populations that once provided additional drones for honey bee mating areas. It is necessary to use...

Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:: Sandahl, Jason
Abstract:: The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

In vivo assessment of nanomaterial-induced toxicity using embryonic zebrafish

Creator:: Usenko, Crystal Y.
Abstract:: Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...
