Distribution of heavy metals in the Sagami River water was examined using the previously devised apparatus for collecting metal ions with a cation-exchange resin columun. The collection was made for 1 week in July, September, and December, 1975,and March 1976. The sampling stations were four points from the upper to lower part of the river. A large number of heavy metals were found in a very high concentration in the middle of the river, but their concentration decreased at the lower part of the river by adsorption on suspended solids. Pb, Ni, and Cu were found in the highest concentrations at station 2,and Mn, Fe, and Zn at station 3. Cd was found in the highest concentration at station 1,as a background, by a geological effect.
