Abstract
Contamination of Dunaliella bioculata by 51Cr and 109Cd was observed experimentally to determine the possible uptake mechanisms of the metals by this alga. Despite slight contamination by 51Cr, it was not possible to demonstrate any active mode of absorption of the radionuclide. In the case of 109Cd, however, the various tests revealed that uptake did occur, the concentration factor being about 300 for a contact time of 15 days with this element.
