금호강 저질(sediment)중에 함유된 중금속의 분포와 오염원과의 상관성 검토

Abstract

The sieved sampling of the sediments of the Kumho river was carried out along 5 minor tribrtaries 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 follows: 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 Palge should no be underestimated.
