项目摘要

Determinations of Mg-, Ca-, Cr-, Mn-, Fe- and Ni-content(P. densiflora), konara(Q. serrata)and ryoubu(C. barbinervis)which were grown on the serpentine soil, were performed by the neutron activation method or the atomic absorption spectrophotometry. It was also found that Hi content in the leaves of konara as well as of ryoubu reflected the concentration of the acid extractable Ni in the serpentine soil. The elemental contents in akamatsu leaf was heavily affected by the characteristic contents of the serpentine soil. It is suggested that these trees are available for the indicator of sail- environment.The radial distributions of Sb content in the stems were analysed for akamatsu, konara and sugi(C. japonica)grown on the Sb-polluted soil. In the same way those of Cu content were also determined for akamatsu, ryoubu and sugi grown an the Cu-polluted sail. 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.The profiles of the radial distribution of alkali metal in softwood, hardwood, and mangrove were different, but, the profiles in softwood(sugi, akamatsu, and todamatsu)and hardwood(mizunara, kuri, and konara)were very similar.

本文对密花松、魔芋、魔芋中镁、钙、铬、锰、铁、镍含量进行了测定。serrata）和ryoubu（C. barbinervis），通过中子活化法或原子吸收分光光度法进行测定。此外，还发现，高含量的魔芋以及ryoubu叶反映了浓度的酸提取镍的蛇纹石土壤。赤松叶片中元素含量受蛇纹土特征含量的影响较大。本文分析了赤松、小原和杉（C.在Sb污染土壤上生长的水稻。用同样的方法测定了生长在铜污染帆上的赤松、ryoubu和杉的铜含量。结果表明，碱金属在针叶、阔叶和红树林中的径向分布特征不同，但在针叶（杉、赤松和户松）和阔叶（水原、库里和科娜拉）中的径向分布特征非常相似。
