  Heavy metal content of twelve vegetable samples procured from local markets in Benin and Lagos cities is estimated by wet digestion and atomic absorption spectrophotometry. The metals include Fe, As, Pb, Hg, Cd, Cr, Zn and Ni. The results obtained from the study revealed that Fe has the highest concentration in all the vegetable samples with values ranging from 1.040-13.97 μg g-1. Hg was found to be below detection limit in all the samples. The levels of the various heavy metals in the vegetable samples studied were found to be in the order: Fe > Zn> As> Ni> Cd> Cr> Pb> Hg. The overall heavy metal levels in most of the vegetables analysed fell under safe range of concentration with few exceptions.
