In situ kinetics of mercury bioaccumulation in mytilus galloprovincialis estimated by transplantation experiments ArchiMer
Casas, Stellio; Cossa, Daniel; Gonzalez, Jean-louis; Bacher, Cedric; Andral, Bruno.
Monitoring coastal contamination by trace metals pollution using mollusks bivalves as quantitative bioindicators is widely performed in many international biomonitoring programs. For this purpose, studying mercury dynamic in marine mussels is a reliable tool. In situ experiments on uptake and elimination kinetics were conducted in three Mediterranean sites, chosen on the basis of their contamination levels. Mussels were transplanted from a clean area to a highly contaminated one and then transferred back to a clean site. This approach makes it possible to define bioaccumulation factors and uptake and elimination rates consistently with the real environmental conditions.

Modeling trace metal accumulation in the mediterranean mussel, mytilus galloprovincialis ArchiMer
Casas, Stellio; Cossa, Daniel; Gonzalez, Jean-louis; Bacher, Cedric; Andral, Bruno.
Monitoring coastal contamination by trace metals pollution using mollusks bivalves as quantitative bioindicators is widely performed in many international biomonitoring programs. In this purpose, modeling metal dynamic in marine mussels is a reliable tool. It allows understanding the bioaccumulation process which results from the interactions between biological, chemical and environmental factors. To calibrate such a model, kinetic experiments on uptake and elimination were conducted on three Mediterranean sites chosen on the basis of their different nutritive and chemical characteristics.

Modélisation de la bioaccumulation de métaux traces (Hg, Cd, Pb, Cu et Zn) chez la moule, Mytilus galloprovincialis, en milieu méditerranéen ArchiMer
Casas, Stellio.
Monitoring coastal contamination of trace metals using bivalve molluscs as quantitative bioindicators is widely used in many international monitoring programs. The bioaccumulation of metal within an organism results from the interaction between physiological (growth, loss of weight, absorption, accumulation), chemical (metal concentration, speciation, bioavailability) and environmental factors (temperature, SPM, chlorophyll). By utilizing the parameters above in this study, it appears that modeling metal dynamics in marine mussels is a reliable tool. The model allows understanding the bioaccumulation process which results from the interactions between biological, chemical and environmental factors. One of the objective of this study was to couple a...

Modelling trace metal (Hg and Pb) bioaccumulation in the Mediterranean mussel, Mytilus galloprovincialis, applied to environmental monitoring ArchiMer
Casas, Stellio; Bacher, Cedric.
Bioaccumulation of metal within an organism results from interactions between physiological factors (growth, weight loss, absorption and accumulation), chemical factors (metal concentration, speciation and bioavailability) and environmental factors (temperature and food concentration). To account for such interactions in the mussel Mytilus galloprovincialis, we combined bioaccumulation and Dynamic Energy Budget models. Field experiments were conducted to measure uptake and elimination kinetics for two metals (Hg and Pb) in three Mediterranean sites with differences in contamination levels, and to calibrate the models. Metal uptake from water and from food was considered separately. Metal elimination resulted from reproduction and/or from direct excretion....
