Concentrations of Cu, Pb, Cr, Cd, Ni, Fe, Zn, Mg, Ca, K and Na were determined in crude palm oil samples obtained from some selected areas in the Niger Delta region of Nigeria using Atomic Absorption Spectrophotometer and Flame Photometer. The mean concentrations of the metals (mg/100g) in the samples varied significantly (p < 0.05) and were: 7.23-24.20 (Fe); 0.55-1.15 (Cu); BDL-0.45 (Cr); 3.73-17.03 (Zn); 0.25-1.03 (Ni); 0.03-0.78 (Pb); 0.15-1.15 (Cd); 12.28-71.53 (Na); 71.03-146.03 (Ca); 14.90-232.00 (Mg); and 21.23-91.53 (K). The estimated daily intakes (EDIs) for Cr, Ni, Pb and Cd (0.0002 – 0.044, 0.024-0.099, 0.003-0.076 and 0.015-0.112, μg/kg bw /day, respectively) were within tolerable levels. The individual and combined metal target hazard quotients had values that were less than one. Consequently, the crude palm oil in the study area were found to be safe for consumption.
