  • Beyond the 16 EPA priority pollutant PAHs : environmental characterizations of oxygenated PAHs and dibenzopyrene isomers

    Creator:
    Layshock, Julie
    Abstract:
    Polycyclic aromatic hydrocarbons (PAHs) with a molecular weight (MW) of 302 and oxygenated-PAHs (OPAHs) have demonstrated toxicity beyond that of frequently monitored and known carcinogenic PAHs. Airborne particulate matter (PM) was characterized for MW 302 isomers to evaluate risk and air quality indices and OPAHs in order to fill data...

  • Human Exposure to PAHs in Air, Water, and Crayfish

    Creator:
    Paulik, L. Blair
    Abstract:
    There are many links between exposure to environmental pollution and risks to human health. While advances in the fields of toxicology, exposure science, and environmental chemistry have shown light on many of these links, many more research challenges remain. One major challenge is how to accurately characterize the toxicity of...

  • Advances in Passive Sampling : Measuring Chemical Transport and Human Exposures

    Creator:
    Donald, Carey E.
    Abstract:
    Passive sampling devices have been used for decades to measure complex mixtures of bioavailable organic chemicals in a variety of environmental media. More recently passive sampler applications have expanded beyond monitoring chemical concentrations, and this dissertation continues to advance methods of passive sampling on many fronts. Despite their growing use,...

  • Advancement of Passive Sampling Applications for Assessing Contaminant Transport, Bioaccumulation, and Toxicity

    Creator:
    Minick, David J.
    Abstract:
    In the environment, it is the unbound fraction of chemical (Cfree) which is able to diffuse across environmental interfaces and biological membranes. It is therefore Cfree which drives many important biological-environmental processes including contaminant transport, bioaccumulation and toxicity. Passive sampling devices (PSDs) offer a simplified and more accurate approach for...

  • 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...

  • Determination of fluorochemicals in waste-dominated aqueous systems

    Creator:
    Huset, Carin A.
    Abstract:
    While fluorochemicals have been detected all over the world and in wastewater treatment plants, the effect of wastewater effluent on the receiving waters has not been evaluated. In the first study, the mass flow of fluorochemicals emanating from wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...

  • Investigation of mixed N,O-donor dipicolinamide derivative ligands for use in nuclear fuel separations

    Creator:
    Lapka, Joseph
    Abstract:
    In this work, three isomeric forms of N, N'-diethyl, N, N'-ditolyldipicolinamide (EtTDPA) were synthesized. The elements thorium through americium, which make up a significant portion of the actinides in used nuclear fuel (with the exception of curium), and two fission products, molybdenum and technetium, were tested for their ability to...

  • Analytical method development for the identification, detection, and quantification of emerging environmental contaminants in complex matrices

    Creator:
    Place, Benjamin J.
    Abstract:
    The development of analytical methods for emerging contaminants creates many unique challenges for analytical chemists. By their nature, emerging contaminants have inherent data gaps related to their environmental occurrence, fate, and impact. This dissertation is a compilation of three studies related to method development for the structural identification of emerging...

  • 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...
