Creator:: Parker, Bethany A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...
Resource Type:: Dissertation

Creator:: Perkins, Matt J.
Abstract:: Large quantities of the chemical oil dispersant Corexit were applied in the Gulf of Mexico (Gulf) in response to the Deepwater Horizon oil spill. Large data gaps regarding the potential transport, persistence and impact of Corexit in the Gulf existed at the time of the emergency response. Analytical methods for...

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...

Creator:: Brewer, Alex J.
Abstract:: Wastewater epidemiology is an emerging discipline that requires collaborative research involving analytical chemists, drug epidemiologists, and wastewater engineers. Wastewater epidemiology involves the sampling and quantitative analysis of raw wastewaters from communities for illicit drugs and their metabolites. Mass loads (mass per day) and per capita (mg per day per person)...

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...

Creator:: Hu, Yan
Abstract:: This research was undertaken to develop a sensitive, selective, and rapid analytical method to measure ethyl glucuronide (EtG) and ethyl sulfate (EtS) in urine as urinary biomarkers of alcohol exposure. Large-volume injection (LVI) coupled with liquid chromatography / electrospray tandem mass spectrometry was used to eliminate the need for either...

Creator:: Chiaia Hernandez, Aurea C.
Abstract:: A sensitive, selective, rapid analytical method based on large-volume injection (LVI) liquid chromatography/ tandem mass spectrometry was developed using commercially-available hardware that eliminates the need for either off-line or on-line solid phase extraction. Centrifugation followed by the direct injection of 1,800 µL was used for the quantification of illicit drugs,...
Resource Type:: Masters Thesis

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...
