Hair samples were collected from 100 healthy people residing in Esfahan, Iran. The concentration of fourteen elements (Al, Br, Ca, Cl, Cu, Hg, I, K, Mg, Mn, Na, S, V, Zn) were determined by instrumental neutron activation analysis (INAA). The statistical results show that there are significant interrelations between some element such as: (Al-Mn, Al-V, Mg-Ca, Mn-V) and also there is no significant age correlation with any element. In addition, the results of this study are compared with the results obtained in England and New Zealand.
