Due to increase of industrialization in public and private sectors along with urbanization, are reflected in varying degree of pollution in the different compartments (water, soil and air) of environment. The present study has been carried out to understand the tolerance potential of different species of Aspergillus (Aspergillus niger, Aspergillus flavus, Aspegillus fumigatus) isolated from agriculture soil of Kasur irrigated with water contaminated with sewage and industrial effluent. The degree of tolerance of fungi was measured by minimum inhibitory concentration in the presence of different concentration of metals (Cr and Pb) and compared to control sample. Results are shown the variation in the tolerance level of different isolates of Aspergillus. Few isolates are tolerant, moderately tolerant and some are sensitive.
