The concentrations (mg/Kg) of Cr, Co, Cu, Fe, Mn, Ni, Pb and Zn were determined in seven different vegetables which were obtained from sharada, kwakwachi and Jakara irrigation gardens in the Kano metropolis using Atomic Absorption Spectrophotometry (AAS). Samples were collected during both dry and rainy seasons. The mean levels of metals obtained ranged widely from 0.34 mg/Kg Cr to 27.35 mg/Kg Fe. The relative abundance of metals in vegetables analyzed followed the sequence Fe > Zn > Mn > Cu > Ni > Pb > Co > Cr. Reductions of metal levels ranging from 8.25% Fe in onion to 45.19% Ni in Okra were recorded in rainy season samples over those of the dry season. @JASEM
