Abstract: The objective of this study is to determine the level of cadmium and lead in soil where vegetable samples are grown in irrigated farmland of Kaduna metropolis. Twenty sampling sites were selected with one control site. The result of geo-accumulation index (Igeo) in soil showed that most of the samples were practically unpolluted while samples from RGS, KWO and URM are moderately polluted with respect Zn, Pb and Fe. Samples from KKR, KWO and DKA are moderately to strongly polluted with Pb and sample from TDW is also moderately to strongly polluted with Cu whereas soil samples from BNW is strongly polluted in relation to Cu contamination. Infact soil samples collected from irrigated farmlands of Kaduna has its geo-accumulation index where it revealed that most of the samples were unpolluted whereas many were moderately polluted by the analyzed heavy metals
