• Resumen

  • The production of engineered nanomaterials (ENMs) has grown in last years due to their special physicochemical properties in respect to their bulk counterparts, derived from their small size (1-100 nm). Among the existing ENMs, silver nanoparticles (AgNPs) are widely used in commercial products due to their antibacterial properties. This fact favours their release in the environment, increasing the concern about the hazards that these emerging contaminants might pose for living organisms and human health. Therefore, to understand their effects, it is of paramount importance their characterisation and quantification in environmental and biological samples by adequate analytical methodologies. The research presented in this thesis focuses on the application and improvement of existing analytical methodologies and on the development of new analytical procedures to acquire information about their mobility and bioavailability in soils and also their accumulation, biotransformation and toxicity in edible plants.
