Abstract: | Introduction Mediterranean rivers are characterized by a high flow variability, which is strongly influenced by the seasonal rainfall.
When water scarcity periods occur, water flow, and dilution capacity of the river is reduced, increasing the potential environmental
risk of pollutants. On the other hand, floods contribute to remobilization of pollutants from sediments. Contamination levels
in Mediterranean rivers are frequently higher than in other European river basins, including pollution by pharmaceutical residues.
Little attention has been paid to the transport behavior of emerging contaminants in surface waters once they are discharged
from WWTP into a river. In this context, this work aimed to relate presence and fate of emerging contaminants with hydrological
conditions of a typical Mediterranean River (Llobregat, NE Spain). |
