Effect of metallic aluminum particles on oysters and clams
- 15 Downloads
The effect of powdered aluminum, used in photogrammetric studies of water currents, on the eastern oyster,Crassostrea virginica, and the soft-shell clam,Mya arenaria, was studied under laboratory conditions. Although the metal particles were removed by filtering activity of the organisms, no increase in aluminum was detected in the tissues and no increase was observed in water samples. These aquatic invertebrates apparently react to aluminum particles as they would to any other inorganic material in the same size range.
