Abstract
We investigated quantities and physicochemical characteristics of iron and organic matters eluted with rain water from soils taken at various kinds of forests and agricultural lands in Shizugawa district, Minamisanriku town, Miyagi prefecture in order to know the relationship of land usage and vegetation with supply of organically complexed iron to coastal area. Organic matters with abundant functional groups, which was indicated by absorption and fluorescence characteristics, were eluted by soils taken at conifer forests and agricultural lands. Iron to organic matter ratios in eluates, which were expected to be related with iron binding capacity, were higher for deep layer in the forests, indicating the importance of iron supply by mother material. Oxidation rate constants of iron by organic matters were also examined since some functional groups attribute to the oxidation of iron. The organic matters with higher aromaticity showed higher oxidation rate constant of iron, and thus, indicated slower production of Fe(II), which has high solubility, in the environmental waters.
