This paper reports on the investigation of the distributions of sediments and heavy metals in Sooyoung River and its mouth, carried out during the period from July 1990 and August 1991. Since the samples were saline, water analysis was performed by the method of alkaline KMnO₄ and sediment analysis by acidic KMnO₄. Mercury was digested with both nitric and sulfuric acids, and then determined by dithizone CCl4 method. Cadmium, Zinc, Copper, Lead and Chronium were determined by atomic absorption spectroscopy after aliquots of samples were digested with nitric acid and hydrogen peroxide. Mineral components of sediments were identified by XRD and microscopic analysis. The result are as follows : 1. The ranges of COD of water and sediments were 10.6-54.6ppm and 63-26000ppm respectively. 2. The ranges of concentrations of Cadmium, Lead, Copper and Zinc for water were 0.002 -0.024ppm, 0. 013-0.060ppm, 0.013-0.736ppm, 0.003-0.012ppm, respectively. 3. The ranges of concentration of Mercury, Cadmium, Lead, Copper, Zinc and Chromium for sediments were N.D - 0.09ppm, 0 .1-2.07ppm, 0.32-5 2.35 ppm, 1.04 - 20.67 ppm, 7.1-52.50 ppm and 0.23-5.22 ppm, respectively. 4. The mineral components of the sediments were mainly quartz and feldspar.
