Per- and Polyfluoroalkyl Substances (PFASs): Consumer Products, Protocols, and Percutaneous Absorption

Creator:: Rewerts, Justin N.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic compounds gaining notoriety as contaminants of emerging concern. With the frequent detection of PFAS in the environment, drinking water, and consumer products, awareness and concern from the public regarding PFAS is increasing. The two most notorious PFAS are perfluorooctanoate (PFOA)...

Per- and Polyfluoroalkyl Substances: From Disposition on Consumer Products and Field Materials to Treatment of Contaminated Groundwater

Creator:: Robel, Alix E.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are an emerging chemical class of concern. Recently in the United States, Health Advisory Limits for two PFAS in drinking water were established for perfluorooctane sulfonate and perfluorooctanoate in drinking water (set to 70 ng/L combine concentration) by the EPA. Because of PFAS mobility, persistence,...

Semi-volatile fluorinated organic compounds in Asian and Pacific Northwestern U.S. air masses

Creator:: Piekarz, Arkadiusz M.
Abstract:: Current studies suggest that perfluorinated organic compounds, such as fluorotelomer alcohols (FtOHs) in the troposphere, may be precursors of perfluorocarboxylic acids and perfluorosulfonates in remote regions. Fluorinated organic compounds were investigated in archived extracts collected from remote locations in Okinawa, Japan (HSO) and Mount Bachelor, Oregon (MBO) during the springs...

Full Text:: . Abstract approved: Staci Simonich Current studies suggest that perfluorinated organic compounds

Suspect Screening of Hydrocarbon surfactants in AFFFs and AFFF-Contaminated Groundwater by High Resolution Mass Spectrometry

Creator:: Garcia, Raymmah A.
Abstract:: Aqueous film forming foams (AFFFs) are proprietary mixtures containing hydrocarbon surfactants and per-and polyfluoroalkyl substances (PFASs) that are used to extinguish hydrocarbon-based fuel fires. There is limited information on hydrocarbon surfactants in AFFFs and AFFF-contaminated groundwater even though they are more abundant (5-10% w/w) than PFASs (0.9-1.5% w /w) in...

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...

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...

Per- and Polyfluoroalkyl Substances (PFAS) in Environmental Air-Water Matrices and Light Non-Aqueous Phase Liquids (LNAPL)

Creator:: Schwichtenberg, Trever J.
Abstract:: The presence of per- and polyfluoroalkyl substances (PFAS), organic contaminants first synthesized in the 1940s, has been reported worldwide in a variety of environmental matrices and ultimately in biological systems including humans. Ongoing research into PFAS has included identifying novel PFAS, assessing their fate and transport in the environment, and...

Fluorinated and deuterated surrogates for quantifying microbial transformation of chlorinated ethenes and ethanes in anaerobic groundwater

Creator:: Ennis, Elliot G.
Abstract:: Chlorinated aliphatic hydrocarbons (CAHs) such as vinyl chloride (VC) and 1,-2 dichioroethane (DCA), are wide-spread groundwater pollutants found at many contaminated field sites around the world. Quantitative tools are needed to determine the in situ rates of VC and DCA transformation to ethene in contaminated groundwater. The objective of this...
