The relationship of 5'-nucleotidase activity in lamb muscle tissue to sub-minimal selenium levels administered to their dams

Creator:: Arnold, Margaret Anna
Abstract:: White muscle disease or muscular dystrophy of sheep is a selenium responsive malady common to many areas with an inherent natural deficiency of selenium in the forage. The disease can be prevented in lambs by adding trace amounts (approximately 0.1 ppm) of selenium to the otherwise selenium deficient, forage fed...

Electrochemical Advancement of Solid State Ion Selective Electrodes

Creator:: Bahro, Christopher
Abstract:: The general theme of this dissertation is the development of new analytical sensors to quantitatively study biological and environmental samples in aqueous and non-aqueous environments. A platinum ultramicroelectrode (UME) and a unique carbon-based pH microprobe were used to design a new SECM-based electrochemical bioassay. The Pt UME was used to...

Identification, Quantification, and Risk Assessment of Polycyclic Aromatic Hydrocarbons and their Derivatives in Soil after Steam Enhanced Extraction

Creator:: Santiago Delgado, Lisandra
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants produced mainly from the incomplete combustion and pyrolysis of organic matter. PAHs are among the major contaminants at over 800 Superfund sites, nationwide. Thermal remediation is used as a method to remediate soils contaminated with PAHs through the use of heat to mobilize...

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)...

Quantifying in situ β-glucosidase and phosphatase activity in groundwater

Creator:: Radakovich, Karen M
Abstract:: Enzymes play an important role in the environment, they breakdown natural-occurring and anthropogenic molecules so that they can be transported into cells and utilized. Enzyme assays are routinely used in soil science and oceanography to measure the activities of specific processes and to serve as general indicators of microbial activity....

Deposition and characterization of transition metal oxides from aqueous solution

Creator:: Betterton, Sharon A.
Abstract:: The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

Using Computational and Statistical Methods as an Aid to Study Environmentally Relevant Organic Molecules

Creator:: Dorn, Shelby E.
Abstract:: In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...
