Objectives : Bioaccumulation of heavy metals by fungi has been a major focus of most bioremediation studies owing to the excellent metal binding properties of the fungal cell wall. The capability of fungi isolated from sediments of the Chemu Lagoon to bioaccumulate heavy metals in lagoon water was investigated.  Methodology and Results:  Fungi were isolated using pour plate technique and sub cultured to obtain pure cultures. Fungi isolated included  Aspergillus   candidus, A. fumigatus, A. niger, A. tamarii, Mucor rouxii, Penicillium notatum  and  Rhizopus sp .  Aspergillus fumigatus  and  Aspergillus niger  were selected for heavy metals bioaccumulation studies on PDB-amended with lagoon water in ratios of 1:1, 1:3 and 1:5 respectively for 3 weeks. Lead and Iron were the most bioaccumulated metals in  A. niger  and  A. fumigatus  with levels of 36.92 mg/L and 73.09 mg/L respectively. Bioaccumulation of heavy metals by both fungi during the wet season was higher than the dry and semi-wet seasons.  Conclusions and applications of findings:  Both  Aspergillus   fumigatus  and  Aspergillus   niger  have good potential for the remediation of heavy metals in polluted water bodies. Comparatively  A. fumigatus  is a good candidate for Arsenic accumulation whilst  A. niger  is good candidate for Cadmium. The relatively longer period of inoculation of media with fungi is essential in increasing the levels of toxic metals accumulated by fungi. The ability of  A. fumigatus  and  A. niger  to bioaccumulate less toxic metals such as Iron, Lead and Zinc at high concentrations in the presence of more toxic metals could imply their versatility in tolerating and or bioaccumulating both classes of metals.Key words:  Bioaccumulation potential, fungi, heavy metals, Aspergillus, Chemu lagoon.
