| Trace metal concentrations (Pb, Ni, Cu and Zn) in the mussel Donax trunculus and the sediments of Annaba estuaries, North-East Algeria were studied. D. trunculus is a widely consumed species by local population. Samples were collected from four sites located alongside Annaba coastline, and exposed to different types and degree of urban and industrial pollution. Results have indicated that the concentrations of Pb, Ni, Cu and Zn are higher in sites which are close to Annaba city. On the other hand, metal concentrations are almost similar between males and females, with only few exceptions. Generally, the concentrations of Pb, Ni, Cu and Zn of sediment have followed the same trend as that of D. trunculus. This study suggests that the species and the sediment as well might be used for monitoring trace metal pollution in Annaba estuaries. It is also suggested that this species is not recommended for fishing and for human consumption in sites near Annaba city. |
