"The presence of emerging environmental contaminants in water bodies used either as drinking water or for recreational purpose has received considerable attention in the recent years. The emerging environmental contaminants can be defined as a wide range of chemicals that have been determined in the environment which may present serious health risks for humans. The occurrence of these contaminants indicate that both household and industrial chemicals have been introduced to water resources, a wide variety of chemicals, such as disinfection byproducts, pharmaceutical and personal care products and so on, have been detected at cetiain levels in either water bodies or treatment plants in worldwide. Although developments in new regulations and detection methods have taken place in the past decades that impact water analysis, there is currently no validated EPA or consensus organization methods for many of the listed emerging environmental contaminants. This body of work developed LC/MS/MS or ICP-MS based techniques for water analysis of several classes of emerging environmental contaminants, including herbicides degradation byproducts; cyanotoxins; N-nitrosamines and heavy metal leaching from plastic bottles. In addition, the developed methods were used to conduct high throughput screening of these emerging contaminants in water samples of various types, and to investigate the removal efficiency of these contaminants by using various oxidants and physical treatment with emphasis on analysis and treatment"--Abstract, page iv.
