Radial distribution of Sb and Cu in the stem of woody plants grown on the Sb-polluted soil as well as on the Cu-enriched soil near an ore dressing house of copper mine

The elemental contents of tree rings can reflect annual variation in an environment. The radial distributions of Sb content in the stems were analysed for akamatsu (P. densiflora), konara (Q. serrata) and sugi (C. japonica) grown on the Sb-polluted soil. In the same way those of Cu content were also determined for akamatsu, ryoubu (C. barbinervis) and sugi grown on the Cu-polluted soil. It was found that among these woody plants a sugi stem was available for the Sb-indicator and an akamatsu stem for the Cu-indicator, respectively. (author)
