contaminants of emerging concern in mediterranean watersheds

Abstract

The present chapter provides a general perspective on the occurrence, ecotoxicological risk, and prioritization of emerging and classical contaminants in Mediterranean river basins with special focus on the Iberian Peninsula as representative case, in the light of the results recently obtained. Risk assessment and prioritization criteria based on ecotoxicological risk with respect to different trophic levels are explained and applied to the Mediterranean basins studied. This enables to rank contaminants according to their ecotoxic risk and to quantify their joint effect as a mixture on a river site.
