Métodos analíticos para la determinación de compuestos disruptores endocrinos stars

Resum

This thesis, entitled "Analytical methods to determine endocrine disruptor compounds", is presented as a compilation of the scientific articles published during the research about the determination of endocrine disruptors in different kind of samples. In the last years the concern about the occurrence of endocrine disruptor compounds (EDCs) in environmental samples and the human exposure to these compounds has increased. The goal of the research collected in this memory is to develop simpler, faster and more economical analytical methods for the determination of EDCs such as brominated diphenyl ethers (BDEs), alkylphenols (APs), bisphenol A (BPA), perfluorinated compounds (PFCs) or organophosphorus flame retardants (OPFRs) in different types of samples. This memory begins with a general Introduction (in Spanish) that explains the importance of the determination of endocrine disruptor compounds and a brief description of the extraction techniques used: selective pressurized liquid extraction (SPLE), focused ultrasound solid-liquid extraction (FUSLE) and microextraction by packed sorbents (MEPS). Then, there are different chapters for each family of compounds. Each chapter is composed by a description of the properties, uses and effects of the compounds in the environment and in human health and the state-of-the-art of their determination in different kind of samples (in Spanish), followed by the corresponding papers, in their original version (English). The scientific articles included are the following: Chapter 2: Brominated diphenyl ethers 1.
