Abstract
The main objective of this study was to assess the concentration levels and the seasonal variations of 13 poly- and perfluoroalkyl substances (PFASs) in different compartments (water, sediments and fish) of the Ebro Delta (NE Spain) and surrounding coastal areas. Perfluorooctanoic acid (PFOA) was the most frequently detected compound in waters and sediments. Perfluorocarboxylic acids (PFCAs) were the compounds found at the highest concentrations in water samples. On the other hand, sediments were more enriched in perfluorooctanesulfonate (PFOS) (rangeÂFile in questo prodotto:
