  Forty-two (42) composite soils samples and fifty- seven (57) dusts samples were collected from within Benin City metropolis, southern Nigeria. All the samples were air dried, disaggregated and subsequently analyzed to determine the concentration of heavy metals using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). The pH, Electrical conductivity (EC) and Total Dissolved Solids (TDS) of the samples were also determined. The pH ranges from slightly acidic to alkaline (5.5-7.1) and (6.0-7.2); EC (37.0-860.0 μS/cm) and (100.0-1437.0 μS/cm) as well as TDS (24.1-559.0 mg/L) and (65-934 mg/L) for soils and dusts respectively. Metals concentration in the soils and dusts are: Cu (4-1125 ppm) and (31.0-210.0 ppm); Pb (9.0-2889.0 ppm) and (40.0-440.0 ppm); Zn (29.0- 10000.0 ppm) and (116.0-729.0 ppm); Ni (2.0-52.0 ppm) and (10.0-28.0 ppm); Sr (4.0-969.0 ppm) and (10.0-1..
