Part of the The Handbook of Environmental Chemistry book series (HEC, volume 21)


In this chapter, an overview of the risk assessment (RA) studies carried out in the Llobregat River is presented.

In the first section, general aspects of the RA process, such are occurrence (exposure) and harmful effects are reviewed. Particular emphasis is put on the assessment of mixture toxicity, since it is a key issue on real multichemical exposed scenarios.

The second part is focused on the description of the different RA studies carried out in the Llobregat River, covering the following aspects: general compound risk, pharmaceuticals, pesticides, metals in the whole basin, as well as the application of RA methodologies to water reuse.

Finally, the connection between RA and ecosystem status is discussed.
