Abstract
In the present study two species of blue green algae ( Oscillatoria amoena and Nostoc linckia ) were treated by two kind of heavy mineral elements are cobalt (Co.) and cadmium ( Cd.) in different concentration ( 0.10 , 0.25 , 0.5 , 1.0 and 2.0 ) mg / l for two weeks to know their capability in the accumulation . The results of the study were revealed that , the algal Oscillatoria amoena accumulated more of cobalt element at the treatment ( 2) mg / l was ( 1.726 ) µg /gm of dry weight , whereas , the concentration was ( 1.535 ) ) µg /gm of dry weight in the algal Nostoc linckia at the same treatment. On the other case , the algal Nostoc linckia was accumulated more of cadmium element ( 1.28 ) µg / gm of dry weight on the compares with the algal Oscillatoria amoena which accumulated ( 0.59) µg /gm of dry weight of the same element at the same treatment ( 2) mg / l . A difference was observed between the treatments of the added element concentrations , the concentration of the heavy element was a gradually increases on the algal with the increase of the concentration on the treatment , and from the results of the statistical analysis some significant differences were found on the concentrations of cobalt and cadmium elements on the two algae species between the used treatments
