| Sumario: | The main objective of this thesis is to develop analytical methods to determine a kind of cosmetic ingredients, the UV filters, in the cosmetics themselves, and in environmental matrices such as waters and beach sand. For that purpose, microextraction techniques and chromatographic analysis were employed. Seven studies are exposed. The first two methods presented were developed to analyse UV filters in cosmetics, and they are based on pressurized liquid extraction (PLE) followed by gas or liquid chromatography-tandem mass spectrometry. The following three methods are related to the analysis of the same compounds in water samples by ultrasound assisted emulsification microextraction (USAEME) and solid phase microextraction (SPME). Finally, different methods dealing with the analysis of UV filters in beach sand are presented. |
