The Utilization Of Liquid Chromatography Tandem Mass Spectrometry And Related Techniques For The Analysis And Identification Of Emerging Contaminants In Aqueous Matrices, Matthew Reichert

Dissertations

Environmental pollutants can be found in many ecosystems and cover many different compound classes. The Environmental Protection Agency is responsible for monitoring and regulating several of these classes of compounds which daily enter the environment. However, there are still hundreds, if not thousands, of compounds present in the environment which have yet to be regulated or even identified. The discovery and identification of these unknown emerging pollutants is crucial for the prevention of potential human health risks and irreversible ecological damage.

The research presented is divided into two projects. The first part of this research investigates the disinfectant 3-Bromo-1-chloro-5,5-dimethylhydantoin, which …

Analysis Of Illicit Drugs, Their Metabolites And Other Micropollutants In Water By Liquid Chromatography Tandem Mass Spectrometry, Deepika P. Panawennage

Dissertations

The goal of this project is to develop liquid chromatography tandem mass spectrometry (LC/MS/MS) methods for the analysis of different, novel micropollutants in waste water and natural water. Micropollutants are compounds that can exert adverse environmental and human health effects at low concentrations. Most of these compounds include personal care products and pharmaceuticals, such as antibiotics and controlled substances. In the first part of this study, we focused in the analysis of illicit drugs and drug metabolites because these analyses have the potential to serve as markers of drug abuse. We have detected over sixteen different illicit drugs and their …
