Abstract: The tolerance limits of Nile water phytoplankton to cobalt, zinc and copper was investigated. The results of this study show that the lower doses of tested metals enhanced the growth of Nile phytoplankton which is represented by increase in cell number. On the other hand the moderate and higher concentrations of these metals markedly inhibited the growth of Nile phytoplankton. The pigment fractions of Nile water phytoplankton under various levels of the three metals responded more or less in a similar trend to that of cell number. Regarding species composition, total disappearance of some species with metal treatments was observed, when the number of other species increased.
