Abstract
Cultures of Dunaliella tertiolecta were exposed to five concentrations of cadmium in solution (0.1, 0.5, 1, 5 and 10ppm(mg 1-1)). The accumulation of cadmium by the algae was found to have two phases, an initial rapid uptake followed by a stabilisation of the cellular cadmium levels. D. tertiolecta concentrated cadmium from solution (cone, factor approx. 1350) at exposures up to 1 ppm Cd but exposure to the higher concentrations caused no further increase in the accumulated cadmium concentration of the algae which reached a nmriimim at about 1.5 μg Cd mg1Dunaliella.Keywords
