Abstract
Neutron activation analysis was used to determine the distribution of trace elements in human hair. Hair samples were obtained from five infants (two to seven years of age) with hair length ranging from 15 to 40 cm. The hairs were divided into segments, each of 2.5 cm, starting from the scalp end and trace elements were analysed in each segment. Concentrations of I, Mg, Ca and Cu increased from the scalp end to the tip. Concentrations of Cl and Br decreased inversely. Different profiles of the concentrations of Hg, Se, Ca and Mn were seen in each sample. These results were discussed with reference to the indication of environmental pollution.
