Effet de l'EDTA sur l'accumulation et l'elimination du mercure par la moule Mytilus edulis

The effect of the presence of the chelating agent EDTA on the uptake and loss of mercury from the whole soft parts of the common mussel Mytilus edulis were investigated under laboratory conditions. It is concluded that the EDTA significantly increased mercury accumulation throughout 18 days exposure. During the elimination period the loss rates of mercury by the presence of EDTA were less important than those obtained in natural sea-water.
