        The study was carried out on the pathway and the trend of copper pollution of sediments in the Kumho River. It was difficult to establish the actual copper pollution level of sediment only with a data on copper contents sediment because measured values of copper fluctuated intensely even in an identical sampling station. Then the trianglar coordinate chart method was applied to compare the pictures of copper pollution among different sampling stations with several items (Cd, Cr, Zn, Pb, Mn and Fe) of the measurement. It was useful for the selection of metals in trianglar coordinate chart to check the probable distribution of metal concentration in sediments. The combination of copper, cadimum and manganese was appeared to be most excellant among fifteen combination of metals in trianglar coordinate charts for the investigation of copper pollution. The plot in the Cu-Cd-Mn trianglar coordinate chars successfully account for the pathway of copper pollution of sediments.
