| Abstract | Environmental studies have revealed the significant contributions of vehicular exhaust and nonexhaust emissions to high pollution levels in urban dwellings. The levels and sources of heavy metal contaminations at selected fuel stations in Accra have been investigated in this work. Soil dust samples collected from these fuel stations were analyzed for their elemental concentrations using Energy Dispersive X-ray Florescence (EDXRF). Fifteen (15) elements of interest were identified: Si, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, Sr, Zr and Pb. Contamination factors (CF), Pollution load index and Principal Component Analysis (PCA) were respectively used to verify the levels and sources of contamination of soil dust. Results obtained for the CF showed moderate contamination for V, Cr and Cu while Zn, and Pb were considerably contaminated. Principal Component Analysis identified four sources and their contributions to the elemental contents in the soil dust. Natural crust, vehicular exhaust emission, tyre wear and brake wear were the four sources identified. |
