In this PhD Thesis, different sensitive and environmentally friendly analytical methodologies have been developed for the analysis of a wide group of oestrogenic compounds in environmental and food samples of diverse nature. With this aim, selective extraction techniques, including hollow-fibre liquid-phase microextraction, dispersive liquid-liquid microextraction using ionic liquids, the QuEChERS method and magnetic and non-magnetic micro-dipersive solid-phase extraction using diverse nanomaterials, have been applied. These procedures have been combined with different liquid chromatographic systems such as high-performance liquid chromatography and ultra-high-performance liquid chromatography for the separation and determination of the target compounds using diode array, fluorescence and tandem mass spectrometry detectors.
