金斗熙,宋亨達 慶北大學校 産業開發硏究所 1984 硏究報告 Vol.12 No.-
This study was conducted to investigate the content of heavy metals in water, in basin soils and radish around of the Geumho river. In order to obtain the correlations among the polluted river water, the basin soil and the agricultural products in each others, Zn, Cu, Cd and Pb were primarily measured from August 4 to November 27, 1983. The content of heavy metals in tributary streams has been found more (Zn, 41∼942ppb ; Cu, 32∼421 ; Cd, 10∼43 ; Pb, 2∼24) than main stream (Zn, 21∼248ppb ; Cu, 14∼104 ; Cd, 5∼16 : Pb, 2∼9). In soils of river basin, we estimate that the contents of heavy metals have much difference according to areas, especially the downstreams of Sin-stream, Dalseo-stream and Kongdan-stream were very high (Zn, 246.31ppm, 321.32 ; Cu, 71.84, 89.34 ; Cd, 3.23, 5.07 ; Pb, 80.99, 96.47) due to the industrial sewage. Between the radishes and the soils, Zn(r=0.5787) and Cu(r=0.6007) was correlated, but that of Cd and Pb was not. Between the soils and water, all of the heavy metals (Zn, r=0.8714 ; Cu, r=0.9588 ; Cd, r=0.9812 ; Pb, r=0.8893) were highly correlated.
