Jo. Ojo et al., CORRELATIONS BETWEEN TRACE-ELEMENT LEVELS IN HEAD HAIR AND BLOOD COMPONENTS OF NIGERIAN SUBJECTS, Biological trace element research, 43-5, 1994, pp. 453-459
Elemental concentrations in head hair and blood (whole-blood, erythroc
ytes and plasma) of 28 Nigerian subjects were determined using instrum
ental neutron activation analysis (INAA) and proton-induced X-ray emis
sion (PIXE) techniques. Correlations found between different elements
in hair and blood are reported. Hair levels of both zinc and chlorine
were found to be significantly correlated with their levels in erythro
cytes.
