 note = {The analysis of wood materials for the determination of trace elements by particle induced X-ray emission (PIXE) method was performed. Sap woods and barks of Japanese five tree species (Akamatsu, Pinus densiflora; Karamatsu, Larix leptolepis; Sugi, Cryptomeria japonica; Buna, Fagus crenata; and Mizunara, Quercus mongolica var. grosseserrata) were examined.
Relatively large amounts of Ca, K, Mg, Na, Mn, Si, Fe, Al, Sr, Cu, and Zn were present. Trace amounts of V, Cr, Rb, Nb, Mo, Hg, and Pb were also present in all the samples. Co, Ni, Ga, Ge, Pd, Ag, Sn, Sb, Cs, Ba, Ce, W, Pt, and Au were not detected from sap woods, but some of these elements were present in several barks. In general, the amount of each metal element in the barks was higher than that in the sap woods. The data obtained by PIXE analysis showed good reproducibility with the exception of K, Mg,
Na, and Al. Regarding the Ca and Mn concentrations, values determined by PIXE and those determined by atomic absorption spectra showed a strong correlation.},
