    Determination of trace element levels in human scalp hair in occupationally exposed subjects by XRF
    (Akademiai Kiado Rt., 2001) Dede, Y.; Erten, H. N.; Zararsiz, A.; Efe, N.
    Trace element levels in hair of individuals living in urban areas were determined by energy dispersive XRF. Two groups of subjects were investigated, the first group was assumed to be from a healthy environment, the other one was exposed to a high level of contamination due to working conditions. The results were compared to data reported in the literature. The concentrations of Ca, Fe, Cu, Zn and Pb in the scalp hair were determined and the correlation between hair trace element levels and environmental effects was discussed. The results given by the second group show that environmental exposure effects hair trace element levels which are related to body trace element concentrations.

    Instrumental neutron activation analysis of blood serum
    (Kluwer Academic Publishers, 1995) Tadjiki, S.; Erten, H. N.; Erten, J.
    Instrumental neutron activation analysis has been used to determine 15 trace elements in twelve blood serum samples taken from healthy students at Bilkent University in Ankara. The method allowed the determination of Sc, Cr, Mn, Fe, Co, Zn, Se, Rb, Cs, Ce, Eu, Tb, Hf, Ta and Hg, which occur at the μg.ml-1 to ng.ml-1 levels. There are no values reported for Tb, Hf, Ce, Eu and Ta before. The other results are compared with the values reported in the literature. Most are in the range of the reported values except for Fe, Zn, Se and Cs. © 1995 Akadémiai Kiadó.
