Trace metal distribution in some selected Nigeria leafy vegetables were determined. All the minerals investigated were found present in all the components of the selected vegetables. On the average, zinc was the most abundant metal with averages of 2.82, 1.97 and 2.08 (mg/g) in roots, stem and leaf of the vegetables, while lead was the leafy with averages of 0.07, 0.06 and 0.07 (mg/g), in roots, stems and leaves respectively. Trace metal distribution number (TMDN) indicates that the roots concentrate most of the metals than the stems and leaves.
