Dust samples were collected from car wind screen packed by the road sides in different locations in Aba north and South Local Government Area of Abia State, Nigeria and analyzed for heavy metals using Parkin Elma Pye Unican 400 Absorption Absorption Spectrophotometer (AAS).The results indicated the range of concentration as Chromium; 89.75 ± 1.95 to 114.70 ± 4.0mg/kg at Asa Nnetu, Lead; 297.05 ± 2.0mg/kg at Aba North 2 to 652.05 ± 17.44mg/kg at Asa Nnetu, Copper; 12.75 ± 0.70mg/kg to 34.75 ± 0.75 at Asa Nnetu, Vanadium; 73.70 ± 3.4mg/kg to 113.30 ± 0.26mg/kg in Aba South 2, Iron; 2701.50 ± 1.5 to 2798.33 ± 2.65mg/kg in Asa Nnetu.Manganese, (Mn); 87.30 ± 1.5 in Aba North 11 to 124.50 ± 1.32mg/kg in Asa Nnetu.Cadmium (Cd); 8.0 1.0 in Asa Nnetu to 13.50 ± 0.50 mg/kg in Aba South 1. Statistics showed significant variation in concentrations of Cu, Cr, Fe, Mn and Hg in the two local government areas.Similarly, the concentrations of Cr, Pb, Cu, Cd, Ni, and Hg were above the Nigeria National Environmental Standards and Regulations Enforcement Agency (NESREA) soil quality for industries.The results indicated various levels of dust pollution by heavy metals in the area and so calls for concern due to the health implication of these metals.
