The soil samples were collected at three different depths of 0-5 cm, 5-10 cm and 10-15 cm respectively. The concentrations of some of the heavy metals Cr, Mn, Co, Ni, Cu, Zn and Pb were found to be lower than the threshold limit of 100mg/kg, 0.3 mg/kg, 0.2 mg/kg, 10 mg/kg, 10 mg/kg, 1.5 mg/kg, and 2 mg/kg. However, Fe and Cd recorded a higher concentration value than the threshold limit of 0.3 mg/kg and 0.02 mg/kg in a soil samples collected at a depth of 0-5 cm, 5-10 cm and 10-15cm. The concentration of the heavy metals Fe, Co, Ni, Cu, Zn in vegetable samples (Tomatoes, Onion, Spinach and lettuce) exceeded the maximum threshold limits of 0.3 mg/kg, 0.02 mg/kg, 0.1 mg/kg, 10 mg/kg and 1.5 mg/kg set by FAO/WHO. Also, the concentrations of Cd both 0.06 mg/kg in (Tomato and Onion) and Mn 0.04 mg/kg (Onion) were found to be higher than the maximum limits of 0.02 mg/kg and 0.04 mg/kg set by FAO/WHO. However, Cr and Pb in all the four vegetable samples were found to be lower than the threshold limit of 0.2 mg/kg and 0.1 mg/kg.
