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...

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...

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...

Long-term fertilizer input influences total and bioavailable metal in agricultural soils and crops

Creator:: Pérez, Angela L.
Abstract:: Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...

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...

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...

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,...

Implications for Wildfire Health Recommendations and Remediation Strategies: Source, Fate and Risk of PAHs

Creator:: Ghetu, Christine, C.
Abstract:: (Polycyclic aromatic hydrocarbons) PAHs are widespread in the environment, and are derived from both natural and anthropogenic sources. The physicochemical properties of PAHs along with the wide range of PAH sources leads to their persistence in the environment. Since PAHs are ubiquitous, and have the potential to illicit adverse effects,...

‘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...
