It presents new methods for the determination of MPs in marine sediment, the dynamics of MPs-chemicals association in the marine environment, and further in-vitro bioaccessibility of phthalate compounds and bisphenol A from MPs. Furthermore, this thesis introduces a novel method for PFAS determination in drinking water in response to Directive 2020/2184/EU and it explores a new electrochemical oxidation-based remediation technology.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Microplasticsplastic-related chemicalsperfluoroalkylated substancesbioaccessibility and marine environment230110 Espectroscopia de masas230103 Análisis cromatográfico230109 Espectroscopia de resonancia magnéticadoctoral thesisopen access
