| Summary: | The disposal of waste of all kinds in auto-repair workshop areas in Nigeria is becoming alarming. The study looks into the contribution of different sections in auto-repair workshop to heavy metal pollution in soil .Thirty –two soil samples were collected at an auto-repair workshop in Osogbo, Ikirun, Iragbiji and Iree in Osun State for their cobalt, iron , lead and cadmium level at different sections namely: auto-mechanic
unit, auto welding unit, auto electrician unit and auto painting unit using atomic absorption spectrophotometer.The highest cobalt concentration was obtained in Iree at the auto welding unit, (17.25± 1.10mg/kg), iron had its highest level in Ikirun at the auto-mechanic unit (43937± 35mg/kg) , lead had its highest concentration in Iree at the auto welding unit (2460±16 mg/kg) and cadmium with the highest in Iree at the auto welding unit as well (2.02 ±1.01 mg/kg).Sites studied had higher levels of heavy metals compared to control areas. The general trend of dispersion of metal contamination within the soil profile is iron>> lead>> cobalt>cadmium. Statistical analysis reveals correlation between lead/iron (r = 0.636) at p |
