Contamination by Heavy Metals (Cd, Zn, Cu, and Hg) of Eight Fish Species in the Gironde Estuary (France)
The Gironde estuary, one of the largest in Europe, is considered as a reference ecological system, with all the western European diadromous fish species present. The national biomonitoring program on the coastal marine environment has revealed since 1979 severe metal pollution (mostly cadmium [Cd])...

The Gironde estuary, one of the largest in Europe, is considered as a reference ecological system, with all the western European diadromous fish species present. The national biomonitoring program on the coastal marine environment has revealed since 1979 severe metal pollution (mostly cadmium [Cd]) in oysters collected from the estuary. No data are available on metal contamination levels in fish, despite their ecological and economic importance. We present the results from a detailed study based on 4 metals (Cd, zinc [Zn], opper [Cu], and mercury [Hg]) measured in 4 organs (gills, dorsal skeletal muscle, liver, and kidneys) from 8 fish species illustrating several ecological combinations: European eel (Anguilla anguilla), twaite shad (Alosa fallax), bass (Dicentrarchus labrax), meagre (Argyrosomus regius), flounder (Platichthys flesus), thinlipped grey mullet (Liza ramada), sole (Solea vulgaris), and Canary drum (Umbrina canariensis).
