| Abstract | ||
| Primary productivity one of the most important ecological activities and measures values character to habitat active and producers activity in fixation solar energy and produce food and oxygen, genus (Anabaena, Oscillatoria & Chroococcus) produce (0.0416, 0.0347 and 0.0350)gram/m2/day in lab condition. These values was lowing clearly with cadmium ions (cadmium nitrate) concentrations (0.5-1-1.5)microgram/liter. Anabaena recorded high product values (0.0412, 0.0378 and 0.037)gram/m2/day in all concentration (0.5-1-.5)microgram/liter recoding confidence difference (p=0.05) from Oscillatoria and Chroococcus primary productivity, and monitoring negative correlations between cadmium concentrations and primary productivity values (carbon produce -0.628,p=0.05; oxygen -0.627,p=0.05). | ||
