“…In this respect, techniques such inductively coupled plasma-mass spectrometry (ICP-MS), graphite furnace atomic absorption spectrometry (GFAAS), combustion atomic absorption spectrometry (Comb-AAS), neutron activation analysis (NAA) and total refl ection X-ray fl uorescence (TRXRF) could play a great role to overcome the limitation in sample amounts and the very small concentrations of some TEs [11][12][13][14][15][16]. In addition to the previously mentioned techniques, energy dispersive X-ray fl uorescence (EDXRF) with modern software and combination with chemical procedures also showed a very good capability to determine several TEs with small concentrations [14,17,18].…”

Abstract. The aim of this study was to determine the concentration of Fe, Ni, Cu, Zn and Pb in scalp hair of leukaemia patients and healthy volunteers, using the optimised XRF method. Leukaemia hair samples were classifi ed corresponding to type, growth and age of the participants. The results showed that the studied trace elements (TEs) in both of leukaemia and control groups were positively skewed. In comparison with the control group, lower Fe, Cu, Zn and Pb and higher of Ni medians were found in all studied leukaemia patients. The median rank obtained by Mann-Whitney U-test revealed insignifi cant differences between the leukaemia patients subgroups and the controls. An exact probability ( < 0.05) associated with the U-test showed signifi cant differences between medians in leukaemia patients and controls groups for Pb (lymphatic/control, acute/control), Cu (lymphatic/control, chronic/control), Ni (lymphatic/control, chronic/control) and Fe (chronic/control). Very strong positive and negative correlations (r > 0.70) in the scalp hair of control group were observed between Ni/Fe-Ni, Cu/Fe-Cu, Zn/Fe-Zn, Pb/Fe-Pb, Cu/Ni-Zn/Ni, Cu/Ni-Pb/Ni, Zn/Ni-Pb/Ni, Zn/Fe-Zn/Cu, Pb/Ni-Ni and Ni/Fe-Pb/Ni, whereas only very strong positive ratios in the scalp hair of leukaemia patients group were observed between Ni/Fe-Ni, Cu/Fe-Cu, Zn/Fe-Zn and Pb/Fe-Pb, all correlations were signifi cant at p < 0.05. Other strong and signifi cant correlations were also observed in scalp hair of both groups. Signifi cant differences between grouping of studied TEs in all classifi ed leukaemia groups and controls were found using principal component analysis (PCA). The results of PCA confi rmed that the type and the growth of leukaemia factors were more important in element loading than the age factor.

“…On the other hand, direct solid analysis would be ideal for Cl determination. In fact, direct solid analysis has been employed for Cl determination using inductively coupled plasma mass spectrometry in conjunction with laser ablation (LA) [11][12][13][14] and electrothermal vaporization (ETV) [15][16][17][18]. These sample introduction accessories have been used for Cl determination in coal by ICP-MS [19][20][21][22].…”

“…The U concentration in the single hair strand investigated decreased from 212 to 18 ng/g and correlated with a change in the U concentration in drinking water from 2000 to 35 ng l À1 . In addition, measurements of U isotope ratios showed a natural isotopic composition in the drinking water throughout the whole period, as well as it was the case in the single hair sample analyzed by LA-ICP-MS [69].…”

“…Results for these elements obtained directly by LA-ICP-SFMS are in good agreement with those measured by ICP-QMS on solutions of digested hair samples. Single hair strand analysis collected from a subject [69] who had changed his habits and began ingesting U with drinking water was performed by LA-ICP-MS. Differences in the U content observed along the single hair strand correlated with changes in the level of I in drinking water.…”
