Sample preparation and system calibration for proton-induced X-ray emission analysis of hair from occupationally exposed workers
Blood and urine collections are commonly used to monitor trace element concentration in the body. Hair may also be used. The concentration of many elements is much higher in hair than in either blood or urine and may provide a ready record of a period of exposure to heavy metals. Proton-induced X-ray emission (PIXE) has been used to study trace elements in hair. A method of preparing samples by charring hair and mixing with yttrium-spiked graphite has been developed. Thick targets suitable for PIXE analysis are made. The trace elements K, Ca, Tl, Mn, Fe, Ni, Cu, Zn, Pb, Br, Rb, and Sr are routinely measured in most samples and Cr, Co, As, Bi, Se, Zr, and Cd can be measured in occupationally exposed workers. Helium backscattering and elastic recoil detection are used to determine the major component H, C, N, O, and S. 23 references, 5 figures, 3 tables.
