Synthesis, characterization, and analysis of nitroaromatic compounds

Creator:: McIntosh, Melissa Luana
Abstract:: Nitroaromatic compounds have important chemical applications and can be found in nature as pollution sources. Synthetic nitroaromatic compounds have been used in a variety of materials including explosives, pharmaceuticals, dyes, plastics, and pesticides. These compounds can find their way into the environment through normal or improper disposal methods. Poly-aromatic compounds...

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...

Measuring in situ biotransformation in BTEX-contaminated groundwater

Creator:: Alumbaugh, Robert E.
Abstract:: Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

In situ transformation of toluene and xylene to benzylsuccinic acid analogs in contaminated groundwater

Creator:: Reusser, Dominik E.
Abstract:: The rate of removal of benzene, toluene, ethylbenzene and the xylene isomers (BTEX) from contaminated groundwater is needed to design remediation processes. Benzylsuccinic acid (BSA) and methyl-benzylsuccinic acid (methyl BSA) are unambiguous metabolites of anaerobic BTEX biodegradation. An analytical method for quantitative determination of BSA in groundwater samples was developed....

Quantitative determination of emerging contaminants, solvent stabilizers and fullerene nanomaterials, in biological and environmental systems

Creator:: Isaacson, Carl W.
Abstract:: To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems. A quantitative analytical...

Determination of fluorochemicals in waste-dominated aqueous systems

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...

The identification and quantitation of complex polycyclic aromatic hydrocarbon mixtures in environmental samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

Creator:: Manzano, Carlos A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...

Prediction and Measurement of Polycyclic Aromatic Hydrocarbons (PAHs) Transformation Products in the Environment.

Creator:: Titaley, Ivan A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental contaminants consisting of fused benzene rings. Parent-PAHs, methylated-PAHs (MPAHs), and PAHs with molecular weight of 302 a.m.u (MW302-PAHs) are considered as unsubstituted-PAHs. These unsubstituted-PAHs undergo transformation reactions resulting in the formation of PAH-transformation products (PAH-TPs), or substituted-PAHs, including nitrated-, oxygenated-, and...
