Tannery sludge waste is currently being used by many farmers for the cultivation of vegetables on large scale for human consumption. The study investigated the effect of tannery sludge on some soil properties and levels of heavy metals in Amaranthus hybridus and Corchorus olitorius grown on the tannery amended soil. Pot experiment was conducted and the metals were analyzed using Atomic Absorption Spectrophotometer. The result showed the soil pH, organic matter content and conductivity of the amended soils increase compared to the controls. The sludge amendment led to significant increase in the metals concentrations of soil. It also led to higher concentration of Nickel (15.73 ± 1.17mg/kg) in the leave, Lead (60.41 ± 9.97mg/kg) and Cadmium (1.99 ± 0.85mg/kg) in the root of Corchorus olitorius. While higher concentration of Chromium (348.99 ± 50.31mg/kg) was observed in the root of Amaranthus hybridus. The concentrations, except of Nickel in Amaranthus hybridus tissues were above the WHO recommended safe limits. Though, the translocation factor of all the tested metals in the vegetables tissues were found low, the concentrations in the vegetables are not safe for dietary consumption. Hence, stringent guidelines set for tannery sludge applications on agricultural land should be totally enforced
