L'objectif de ce travail de thèse était d'évaluer l'implication de différents ligands cellulaires dans la séquestration du cadmium, du cuivre et du zinc chez des Mollusques bivalves. Dans le cadre d'une exposition chronique de spécimens de Pyganodon grandis récoltés dans neuf lacs de la région de Rouyn-Noranda (Québec), la concentration en Cd accumulé dépend à la fois de la concentration en métal dissous, de la nature et de l'abondance des ligands de l'organe considéré (branchies versus glande digestive). Dans la glande digestive, le Cd est largement séquestré par la métallothionéine (MT) alors que dans les branchies les granules représentent le principal site de stockage des trois métaux étudiés. Une expérience de transplantation, impliqua...
