Studies of the presence of heavy metals were carried out on some vegetables and crops harvested from farms in Ebocha, Egbeda and Igbo-Etche in Rivers State, Nigeria. These farms are located in communities where oil exploration activities are ongoing. The samples were prepared by wet digestion using a mixture of Perchloric acid (HClO 4): Nitric acid (HNO 3) in the ratio 1:4 and analyzed using Atomic Absorption Spectroscopy (AAS). The heavy metals concentration in almost all the vegetables and crops studied were high compared to the maximum permissible limits prescribed by World Health Organisation (WHO), Food Agriculture Organization (FAO) and
