Use of Targeted and Non-Targeted Analysis to Study Complex PAH Environmental Mixtures

Creator:

Chibwe, Leah

Abstract:

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed from the incomplete combustion of organic material. These contaminants are of concern because of their widespread presence in the environment and toxic properties. In addition, PAHs encompass a class of diverse compounds with varying physicochemical properties and exist in the environment as...

Poly- and perfluorinated alkyl substance release from landfills and landfill model reactors

Creator:

Allred, Brent McKay

Abstract:

Research and public concern of poly and perfluoroalkyl substances (PFASs) as environmental contaminants has increased significantly due to the increasing number of reports of their detection in humans and wildlife. PFASs have a number of commercial applications including surfactants, coatings, polymers, and levelers, which are used on consumer products like...

Per- and Polyfluoroalkyl Substances (PFASs) and Aqueous Film-Forming Foam Impacted Sites : New PFAS Discovery and Sorption of Anionic, Zwitterionic, and Cationic PFASs

Creator:

Barzen-Hanson, Krista A.

Abstract:

Public attention and concern about per- and polyfluoroalkyl substances (PFASs) are increasing due to detection of PFASs in drinking water supplies, the environment, including remote locations, and wildlife and to the lowering of the federal health advisory levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in drinking water. Aqueous film-forming...

Development of novel analytical methods to detect emerging contaminants in aqueous environmental matrices using large-volume injection

Creator:

Backe, Will J.

Abstract:

It is the responsibility of humans, as environmental stewards, to monitor our impact on the environment so that efforts can be made to remediate the effects of our actions and change behaviors. To better understand our environmental footprint, sensitive and simple analytical methods are needed to quantify the contaminants that...

Environmental Matrices using Large-Volume Injection Abstract approved
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...

Semi-volatile organic compounds as molecular markers for atmospheric and ecosystem transport

Creator:

Genualdi, Susan A.

Abstract:

The use of semi-volatile organic compounds (SOCs) as molecular markers to identify the contributions of regional and long-range atmospheric transport, as well as current and historic sources, and contaminant deposition in remote ecosystems of the Western U.S. was investigated. Trans-Pacific air masses influenced by Siberian biomass burning events had elevated...

Determination of fluorinated alkyl substances in aqueous systems

Creator:

Schultz, Melissa M.

Abstract:

Fluorinated alkyl substances, which can be persistent, toxic, and bioaccumulative, have been quantitated in many densely populated and remote regions, including in air, surface waters, groundwater, and biota; however, little is known about their transport or behavior in the environment. Wastewater effluent is one of the principal routes for introducing...

Trans-Pacific and regional atmospheric transport of anthropogenic semivolatile organic compounds in the western U.S.

Creator:

Primbs, Toby

Abstract:

The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...
