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,...

New applications and emerging contaminants : developing silicone passive sampling devices for environmental and novel monitoring applications

Creator:

O'Connell, Steven G.

Abstract:

Passive sampling is a popular technology for environmental monitoring, and silicone is an ideal choice for a variety of passive sampling applications. The silicone work described here encompasses laboratory and field studies that demonstrate the use of this polymer in novel environments, for new applications, and for emerging compounds. Unique...

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...

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...

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...

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...

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...

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...

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...

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,...
