The street children phenomenon is an increasing problem in most cities of the world including Isfahan, which is a fast growing
town. The number of street children with the growth of the town is increased. It is therefore important to have baseline data
on their health problems. Hair element analysis remains an important tool in the nutritional and environmental assessment
of them. A measurement of the elemental concentration in recently-grown hair provides an integrated view of the element status
in the follicular cells and their blood supply, unaffected by short term fluctuations in the nutrient intake of the subject.
This study aimed to assess heavy metals concentrations in the hair of street children in Isfahan using neutron activation
analysis method. The concentration of heavy metals (Cu, Cr, Fe, Hg, Mn, and Zn) of 17 Iranian street children (Isfahan) was
examined. Data analysis found that different profiles of the concentrations of Cr, Hg, Mn, and Zn were seen in each sample.
These results were discussed with reference to show of environmental effects.
