Abstract
The sieved sampling of the sediments of the Kumho river was carried out along 5 minor tributaries to study the distribution of the heavy metals according to particle size and to locate the source of heavy metals contributing to the pollution of the Kumho river which flows through the Taegu city April in 1988. The results were as foil?ws: The heavy metal concentrations generally increased with the decreasing size of sediments and were higher in lower portion of sediment than in upper one at the same particle size. The coefficients of variation of each heavy metal in the same particle size were similar generally; but those among heavy metals showed markedly different values. It was found that the main source of pollution of the Kumho river was the Third Industrial Complex; but the contribution of Paige should not be underestimated.
