Use of carbonyl iron to induce iron loading in the mussel Mytilus edulis
- Murdoch Univ. (Australia)
It is now recognized that in organisms such as marine mussels, the prior presence of one metal can be important in determining the ultimate toxicological response to a second challenge by a different metal species. Thus, for example, the presence of iron in the mussel Mytilus edulis profoundly affects the subsequent accumulation of zinc. To determine these synergistic (or indeed antagonistic) effects in an organism such as the mussel, it is important to be able to both load the animal rapidly, and ensure that the metal ends up in a form which is ultimately the same as that found in the animal in the natural environment. Unfortunately, considerable problems have arisen with the form in which iron has been loaded into mussels. Recently, carbonyl iron has been used to induce iron loading in rats. This form of iron is prepared by reacting elemental iron at high temperatures with carbon monoxide to form iron pentacarbonyl. This study was thus undertaken to determine whether carbonyl iron could be used for the rapid non-toxic iron loading of the mussel Mytilus edulis. Such loading could subsequently be used for the investigation of synergistic metal accumulation in mussels, a topic of considerable interest due to their use as marine pollution indicator organisms. Biochemical aspects of this tissue iron loading, including the isolation and characterization of the major metal-binding protein ferritin, have been reported previously.
