Persistent organic pollutants (POPs) in sediments from fishing grounds in the NW Mediterranean: Ecotoxicological implications for the benthic fish Solea sp.

► Levels of POPs in fishing grounds of the NW Mediterranean are considered as baseline. ► Biliary FACs reflect a higher PAH exposure in the Northern station. ► Both sole fish can be equally adequate for pollution monitoring. ► Immune non-specific parameters respond to PAH exposure.
