| Abstract | ||
| In the present study two species of blue green algae Microcystis aeruginosa and Hapalosiphon aureus were treated with two heavy mineral element were cadmium and lead on the different concentration ( 0.10 , 0.25 , 0.50 , 1.0 and 2.0 ) mg / L for two weeks to know the possibility to the bioremediation . The results of the study were showing that , the alga H . aureus accumulated more of lead element the concentration was ( 1.724 ) µg / gm dry weight whereas , the concentration ( 1.579 ) µg / gm dry weight on the alga M .aeruginosa at the treatment 2 mg / l . On the other hand the algal M .aeruginosa was accumulated more of cadmium element (1.08) µg / gm dry weight as compared with the algal H . aureus ( 0.63 ) µg / gm dry weight at the same treatment .The difference was observed on the concentration of the two element between the different treatments , It was noticed a gradual increase on the concentrations of the two elements on the two species of algae with the increase that occurred on the concentration of the treatments , it was observed from the results of the statistical analysis some of significant differences on the concentrations of lead and cadmium elements on the algae between the used treatments. | ||
