Abstract
Fulvic acid-Fe (FA-Fe) and total dissolved Fe (TD-Fe) in the water of three rivers were measured because ful-vic acid-Fe plays an important role for the growth of photosynthetic organisms in the sea. The fulvic acid-Fe in upper streams from the Shukunohe River was low (ca. 0.2μM) while its concentration in down stream increased gradually to about 3μM as iron due to the inflow of streams with high FA-Fe. FA-Fe in the other rivers showed similar concentrations as those in down stream of the Shukunohe River. The ratios of FA-Fe/TD-Fe in the Shukunohe, Kunebetsu and Ohno Rivers were 82±8, 83±2 and 84±2%, respectively, meaning that most of TD-Fe is FA-Fe.
