Abstract
This paper presents a study and possible relationships between some selected heavy metals in Petroleum products, soil, water and plant samples collected from different points around the Nigerian National Petroleum Corporation (NNPC) satellite depot, Ejigbo with samples from Ojo campus of the Lagos State University as the control samples. Cadmium was not detected in water, Ireland control sample but was detected in soil, which ranges from 0.04 ug/g and N.D to 0.80 g in plant samples. Lead was detected in the range of 0.082 ug/L to1.43 mg/L in petroleum products, soil, 0.070 ug/g to 3.2 ug/g and plant, N.D to 0.5 ug/g. The range of Iron in the soil sample was 58.11 ug/g to 122 ug/g, plant 18.72 ug/g to 96.5 ug/g water N.D to 58.11 mg/L as against the control soil 26.0 ug/g to 60.0 ug/g plant 22.4 ug/g to 64.0 ug/g and water N.D to 0.24 mg/l. Zn was detected in the range 14.2 ug/g to 62.0 ug/g in soil samples, plant sample 24.3 ug/g to 88.4 ug/g as against control soil 10.00 ug/g to 21.25 ug/g, plant 11.8 ug/g to 31.6 ug/g and water. These results implied that consumption of food and water within and around such areas might be under threat as there is a gradual accumulation of heavy metals with possible displacement of essential minerals in bio-activities within the consuming organisms which eventually will impact negatively on health and well-being as most of the metals are considered carcinogenic.
