In the present study using Aspergillus niger, Candida albicans and Cryptococcus neoformans for investigating about the effect of (Cu, Mg and Zn) on the growth it under laboratory condition in liquid and solid media. In liquid media Cu, Zn ions were inhibited growth of A. niger where as Mg ion was increase the growth, while lead to added three heavy elements to inhibited of C. albicans and C. neoformans except copper ion in concentration 40 ppm lead to increased growth C. neoformans compared with control. Solid medium was used to study the effect of these ions on the numbers of colonies generally the three fungal species decreased in colony number by effect three heavy metals, except Copper, Magnesium appeared effect positively by increased number of colony for A. niger during 24 hours.
