Resumen:
This thesis is part of the Total Diet Study project (TDS) of pollutants in Catalonia. The EFSA established that TDS provides the results or value of exposure on a representative population. A TDS consist of: Sampling selection, collection, homogenization and data analysis. Otherwise, the WHO includes the Duplicate Diet's methodology (DD). The DD has the same characteristics of the TDS, with the particularity that homogenized are menus based on normal mixes diets. The pollutants selected were: Polycyclic Aromatic Hydrocarbons (PAHs), Arsenic, Cadmium, Mercury, Lead, and Perfluoroalkyl Substances. The study of PAHs was done for TDS and DD. The food selection was conditioned by the most consumed raw products of Catalonia (Spain). Results: The dietary intake of all pollutants is situated below the recommendation established by government agencies. According to the results of PAHs for both methodologies DD studies might be a good alternative, especially when economic limitation are present.
