    Abstract

    The heavy metal (Cd, Ni, Pb, Zn and Cu) contents of soils and of reed, Phragmites australis (Cav.) Trin. ex Steudel, sampled from freshwater and brackish-water reed stands in the lower reaches of the Nanakita River, Miyagi Prefecture, Japan, were measured. The heavy metal contents of soils showed a positive correlation with organic contents, and were higher in the brackish-water stand than in the freshwater stand, even when the levels of organic contents were equal. In the brackish-water stand, heavy metals are probably accumulated as sulfides. Heavy metal concentrations in reed roots showed higher values than those in leaves, stems and rhizomes. The ratio of the concentration in reed roots to that in soils (availability of heavy metals) was high in the freshwater stand as compared with the brackish-water stand.
