The present chapter provides a review of the occurrence, fate, and risk associated to different families or emerging and priority organic micropollutants in the rivers of Catalonia. Compounds belonging to diverse groups such as industrial compounds, perfluoroalkyl substances, pesticides, halogenated flame retardants, pharmaceuticals and hormones, personal care products, and illegal drugs, as well as their transformation products, are examined. Both emission levels from sewage systems and those found at the receiving water bodies are compared. Potential fate and transformation of the parent compounds is taken into consideration. Finally their environmental risk in terms of the associated ecotoxicity with respect to three trophic levels (Daphnia, algae, and fish) as recommended by the WFD is assessed. This prioritization exercise allows identifying those micropollutants that are more relevant in Catalonian Rivers.
