Cadmium and mercury in Seine Estuary flounders and mussels: the results of two decades of monitoring ArchiMer
Nakhle, K; Cossa, Daniel; Claisse, Didier; Beliaeff, Benoit; Simon, S.
The flounder (Platichthys flesus) is a flatfish that inhabits marine coastal environments, especially estuaries. It is an alternative quantitative biological indicator to the common marine mussel (Mytilus spp.), which is currently used as a sentinel species to monitor chemical contamination in numerous monitoring programmes. Findings from two decades of monitoring cadmium (Cd) and mercury (Hg) using both sentinel species in the Seine Estuary (France) are reported. For comparison, time-series of water concentrations for the same two metals at the mouth of the River Seine are given. Cd concentrations in the liver of the fish and in the soft tissue of mussels show similar temporal trends, consistent with the major temporal variations of Cd concentrations...

Cs-137 baseline levels in the Mediterranean and Black Sea: A cross-basin survey of the CIESM Mediterranean Mussel Watch programme ArchiMer
Thebault, Herve; Baena, A; Andral, Bruno; Barisic, D; Albaladejo, J; Bologa, A; Boudjenoun, R; Delfanti, R; Egorov, V; Khoukhi, T; Florou, H; Kniewald, G; Noureddine, A; Patrascu, V; Pham, M; Scarpato, A; Stokozov, N; Topcuoglu, S; Warnau, M.
The common mussel Mytilus galloprovincialis was selected as unique biomonitor species to implement a regional monitoring programme, the CIESM Mediterranean Mussel Watch (MMW), in the Mediterranean and Black Seas. As of today, and upon standardization of the methodological approach, the MMW Network has been able to quantify Cs-137 levels in mussels from 60 coastal stations and to produce the first distribution map of this artificial radionuclide at the scale of the entire Mediterranean and Black Seas. While: measured Cs-137 levels were found to be very low (usually <1 Bq kg(-1) wet wt) Cs-137 activity concentrations in the Black Sea and North Aegean Sea were up to two orders of magnitude higher than those in the western Mediterranean Basin. Such effects,...
