Aspergillus species (Aspergillus niger, Aspergillus versicolor, Aspergillus fumigatus and Aspergillus flavus) were isolated from tannery effluent collected from a tannery industry located at Challawa industrial estate of Kano State, Nigeria. The Aspergillus species were screened for their ability to tolerate and bioaccumulate chromiumand cadmium present in the tannery effluent. Also, the interactions between the fungi biomass and the heavy metals was also studied through the use of Fourier Transform -Infra red (FT-IR) technique. Results of the frequency and percentage occurrence of the Aspergillus species showed that Aspergillusniger recorded the highest frequency of occurrence of 36 which represented 39.1% of the total number of the Aspergillus species isolated across the sampling points while both Aspergillus fumigatus recorded the least frequency of occurrence of 13 which represented 14.1% of the total number of the Aspergillus species isolated across the sampling points.
