The Study dealing with the influence of heavy metal(Pb) separately in the growth of the algae Microcystis &
chroococcus (cyanophyta)under lab. Conditions,the parameters were total cell count by slid chamber.The results
indicates that the toxic effect of studied heavy metals depend upon metal construction,lowest total cell count . lead
ions was added to the culture media as aconcetration (0.5, 1, 2,4)mg/l . the (4)mg/l concentration was more toxicity
for both algae , the minimum chroococcus colonies count was (62) colony and (66) colony in microcystis at (4) mg/l
concentration. By measuring inhibit rate for both algae,found , Microcystis was more resistant lead than other
algae.Obsorved increase toxisity increased period was concentration of 4% toxcisity for both algae.
