Comparative study of the patterns of bioaccumulation of essential (Cu, Zn) and non-essential (Cd, Pb) trace metals in various estuarine and coastal organisms
The patterns of accumulation of essential and non-essential trace metals have been studied comparatively in worms, molluscs, crustaceans, and fish exposed to short-term experimental contaminationsExpand

Accumulation and Soluble Binding of Cadmium, Copper, and Zinc in the Polychaete Hediste diversicolor from Coastal Sites with Different Trace Metal Bioavailabilities
Bioaccumulation of cadmium, copper, and zinc was examined in common ragworms Hediste diversicolor from control (Bay of Somme, Blackwater) and metal-rich (Seine estuary, Boulogne harbor, RestronguetExpand

Estimates of trace metal bioavailability to humans ingesting contaminated oysters.
Oysters, as very popular food items in France, are subject to rules concerning the maximum acceptable contents of trace metals in foods. The food standards for the quantities of metals permitted areExpand

Determination of Cadmium Partitioning in Microalgae and Oysters: Contribution to the Assessment of Trophic Transfer
Alternative methodologies have been applied to the study of cadmium transfer in a food chain: water, microalgae (Skeletonema costatum and Tetraselmis suecica), oysters (Crassostrea gigas). TheExpand

Bioaccumulation, toxicity and physico-chemical speciation of silver in bivalve molluscs: ecotoxicological and health consequences
Abstract The toxicity and bioaccumulation of silver have been studied comparatively in the freshwater bivalve Dreissena polymorpha and in four marine species: the oyster Crassostrea gigas, the musselExpand

A suitable model for the biomonitoring of trace metal bioavailabilities in estuarine sediments: the annelid polychaete Nereis diversicolor
The need to use biomonitors representative of the sedimentary compartment has been recognized, particularly in estuaries. Thus, trace metal contamination has been monitored in an infaunal polychaeteExpand

Contribution to the ecotoxicological study of cadmium, lead, copper and zinc in the mussel Mytilus edulis
The understanding of natural fluctuations of metal concentrations in mussels used as bio-indicators is indispensable for a good assessment of the disturbances due to pollution. We have studiedExpand

The potential use of metallothionein in the clam Ruditapes decussatus as a biomarker of in situ metal exposure.
This work aimed to validate the relationship between metallothioneins (MTs) and metals (Cd, Cu and Zn) in field conditions. Specimens of the marine bivalve Ruditapes decussatus (Linné, 1758) fromExpand

In situ potential use of metallothionein as a biomarker of cadmium contamination in Ruditapes decussatus.
Cadmium (Cd) and metallothionein (MT) concentrations were analysed in the gills and digestive gland of clams Ruditapes decussatus collected from two sites of the Gulf of Gabès (Tunisia) which differExpand
