The levels of Pb, Fe, Cd, Ni, Mn and Cr were determined in dust samples collected weekly for sixteen weeks from December 2009-April 2010, from a commercial area (Community market) and a residential area (Akenzua postgraduate hostel) in Ahmadu Bello University Zaria, in order to determine its pollution status with regards to air. Flame AAS technique used for the analysis indicated the order of relative abundance to be Fe>Pb>Ni>Cd>Mn>Cr for commercial area; Fe>Pb>Ni>Mn>Cd>Cr in residential area. Analysis of variance with t-test showed that there was no significant difference between metal concentrations within the study area. The deposition rates for the residential area showed a mean of 1.76g/m2 and the commercial area showed a mean of 2.46g/m2. Analysis with t-test showed no significant difference between deposition rates for commercial and residential area. The enrichment factor analysis showed anthropogenic activities as a major source of these metals in the dust.
