Integration of embryonic zebrafish and passive sampling device extracts to explore effects of pesticide mixtures

Creator:: Corvi, Margaret
Abstract:: Pesticides are ubiquitous, with more than one billion tons of pesticide products used in the United States annually. These compounds are characterized by their toxic effects to the target organism; however, pesticides are also well known for their deleterious effects to non-target species. Because pesticides have ecological and human health...

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 of a colorimetric test kit to determine enzymatically produced pyruvic acid in sweet onions

Creator:: Merrill, Dawn C.
Abstract:: Sweet onions are valued for their unique flavor and praised for their health and dietary character. Onion sweetness is perceived as the degree of pungency decreases. Pungency can be quantitatively determined in onions by measuring enzymatically produced pyruvic acid. The onion industry quantifies a sweet onion as one having a...

‘Tis a Gift to be Simple : On Passive Sampling and Compatible Techniques for Reducing the Complexity of Environmental Mixtures

Creator:: Bergmann, Alan J.
Abstract:: Assessing the risk from exposure to a chemical mixture in the environment can seem prohibitively challenging. Most components of the mixture are not readily identifiable, chemicals may interact to cause other-than-additive toxicity, and the number of potential combinations of environmental contaminants is enormous. These challenges can make it seem impossible...

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...

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...

Development of innovative applications for passive sampling devices : monitoring bioavailability, risk from exposure and environmental mixture toxicity

Creator:: Allan, Sarah E.
Abstract:: Chemicals must be bioavailable for there to be a potential for exposure and consequent risk to human or environmental health. Passive sampling devices (PSDs) are used to quantify the time-integrated concentration of bioavailable contaminants. We demonstrate that PSDs can be paired with the zebrafish developmental toxicity bioassay to produce site-specific,...

Applications of Silicone Wristbands to Improve Personal Chemical Exposure Assessment

Creator:: Dixon, Holly M.
Abstract:: Silicone wristbands are easy-to-wear passive samplers that have been readily adapted into environmental health studies since first reported in 2014. Wristbands can be worn during normal daily activities and sequester a wide range of bioavailable organic chemicals. This dissertation includes a thorough review of silicone wristband technology, as well as...

New Configurations of Silicone Passive Sampling Devices: Quantifying Feline and Firefighter Chemical Exposures

Creator:: Poutasse, Carolyn M.
Abstract:: Silicone wristbands are passive sampling devices (PSD) that sequester bioavailable organic chemicals in the environment. In environmental health studies, silicone wristbands are easy to wear and can provide personal exposure data about complex chemical mixtures. This dissertation includes an overview of PSD technology, a literature review of current wristband research...

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...
