英文摘要： In last few years, there is increasing concern over the presence of emerging contaminants in global aquatic ecosystems, since the number of potentially hazardous chemicals that can reach the environment is continuously increasing and new chemical substances are constantly being synthesized and released. Due to the potential adverse effect of human health or ecosystem safety, the comprehensive and objective study of organic pollutants in aquatic environment becomes a major concern. In this study, a systematic study strategy on the multiclass analysis of trace organic pollutants will be established to obtain a realistic and more complete overview of the organic pollution present in water. Because of the complexity of the aquatic system, the large variety of organic contaminants, the low analyte levels, with quite different physicochemical characteristics, a series of pretreatment procedures using solid-phase extraction (SPE) will be investigated to concentrate the analytes prior to instrument analysis. To simultaneously realize target, post-target, and non-target organic contaminants screening, an complementary analytical strategy will be applied by combining two powerful techniques, gas chromatography(GC) and liquid chromatography(LC), both hyphenated with triple-quadrupole analyzers (MS-MS) and time-of-flight ma
