Abstract

This study evaluated the level of different selected heavy metals namely; Cadmium (Cd), Copper (Cu), Lead (Pb), Manganese (Mn) and Zinc (Zn) pollutants in soil sample, from Azare mechanical workshop (Babban Gareji), Katagum Local Government, Bauchi State, Nigeria. The soil were collected using stainless steel soil auger, from the surface to about 15cm soil depths, 4 core different samples randomly taken were homogenized in a clean plastic bucket and composited to represent a sample. The representative soil samples (4) were taken to the laboratory, dried, crushed and sieved to remove larger particles. Ten cube of centimeters (10cm³) of 1:3 ratio of HNO₃ and HCl was added to 2.0g portion of the soil sample on a hot plate until a clear solution was obtained, the content of the beaker was then allowed to cool. Twenty cube centimeters (20cm³) of distilled water was added and then filtered using filter paper (0.45µm) in 100cm³ volumetric flask. The solution was analyzed for the levels of Cadmium, Lead, Manganese, Copper and Zinc using Atomic Absorption Spectroscopy (AAS) technique. The results obtained showed the following levels for Cd 0.0265 mg/kg, Pb 3.0746 mg/kg, Mn 1.2466mg/kg, Cu, 2.4113 mg/kg and Zn 0.4557 mg/kg respectively for the soil samples from mechanical workshop, while that of control samples was Cd 0.0533mg/kg, Pb 0.1398 mg/kg, Mn, 0.4890 mg/kg, Cu 0.2541 mg/kg and Zn 0.0376 mg/kg respectively. The results of heavy metals obtained from the analysis of soil from the mechanic workshops indicated that their concentrations are relatively higher than that of the control sites but lower than the WHO standard except for manganese which is higher than the WHO standard.
