title: Baseline levels of elemental concentrations in whole blood, plasma, and erythrocytes of Nigerian subjects.
abstract: In this pioneering effort on Nigerians, the arithmetic means, ranges, and standard deviations for the concentrations of the 13 elements, Br, Ca, Cl, Cu, Fe, K, Na, P, Pb, Rb, S, Se, and Zn, detected in freeze-dried whole blood, erythrocytes, and plasma of 120 subjects drawn from different geographical regions of Nigeria are reported. Elemental analyses have been carried out largely using instrumental neuron activation analysis (INAA) with both proton-induced X-ray emission (PIXE) and graphite furnace atomic absorption spectrometry (AAS) serving as complementary techniques. Our values, compared with similar data from other parts of the world, show a general good agreement. Values in male and female subjects are compared. Correlations between different elements are also noted.
