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...

Assessing Exposures and Simplifying Complex Mixtures of SVOCs for Hazard Characterization using Alternative Model Systems

Creator:: Rivera, Brianna N.
Abstract:: Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...

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,...

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...

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...

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,...

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...

‘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...

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...

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,...
