Abstract: There are two fundamental difficulties associated with the monitoring and determination of emerging contaminants. First, the matrices are complex. Second, the target analytes are usually found in trace levels. To address these limitations, a combination of powerful sample preparation method with a highly sensitive instrumental analysis is highly desirable. Therefore, the main objective in this thesis is trying to develop analytical methodology for the quantitative determination of Perfluorinated carboxylic acids from water samples, human plasma and fish fillets. Moreover, it describes the developed methods for determination of N-Nitrosamines from swimming pool water, wastewater, and different alcoholic beverages. The methods are based on micro-solid phase extraction, by using ordered mesoporous materials as sorbents, and following analysis by liquid or gas chromatography coupled to tandem mass spectrometry. Combination of these two approaches makes the reliable, practical, and cost-effective process for the routine analysis.
