This study assesses heavy metals’ concentrations in fourteen leafy vegetables from popular markets in Ekiti State, Southwest, Nigeria using atomic absorption spectrophotometer (Buck Scientific Model- 200A/210, Norwalk, Connecticut 06855). The results (mg/kg) were: Cd (0.0001-0.540), Mn (0.00012-0.024), Pb (0.0001-0.0016), Cu (2.60-8.07), Zn (6.80-19.7) and Fe (3.23-10.9). The values were generally lower than the joint FAO/WHO standards for food additives except for Zn in all the vegetables. Generally, estimated daily intakes were all below the tolerable daily intake for both adults and children set by FAO, WHO and USEPA. EDI/Df of Cu for all the vegetables was between 3.75 and 26.3 times higher than the corresponding Df. For adults and children, HI and TCR, 0.208-3.18 and 4.48e-6-0.247, indicated low to moderate carcinogenic health risks. Excess intake of these vegetables on regular basis is a matter of concern for heavy metal toxicity and non-carcinogenic health risks.
