• Note (General): This thesis can be divided into two major parts: 1) Development of a comprehensive screening method for 311 LC-MS-amenable organic chemicals with a wide range of physicochemical properties (log Pow: -2.2-8.53) using a combination of solid-phase extraction and liquid chromatography time-of-flight mass spectrometry. First, method optimization using 128 pesticides revealed that tandem extraction with styrene-divinylbenzene polymer and activated carbon solid-phase extraction cartridges and setting sample water pH 7.0 provided the highest recovery. The following Spike recovery test of 190 model compounds using reagent water and sewage treatment plant effluents proved this method could be applied to wastewater. 2) Application the new method to monitor organic micro-pollutants in the aquatic environment in Vietnam. The results show that many pharmaceuticals and agricultural chemicals were detected at high concentrations in the Vietnamese rivers and it became obvious that some detected chemicals could effect on aquatic ecosystems.
