1he Characteristics of Distributioo 00 the Heavy Metals in Soil of Kumho River Basin

This study was carried out to investigate the pollution of heavy metals in soil of seven stations from the upper spot(Yeungchun Dam) of Kumho River to the downstream(Gangchang Bridge). The results obtained were as follows: 1. The content of heavy metals in soil of Kumho River basin was highest at Gangchang Bridge [expresed in μg / g Mn(246.0). Cd(l .90) , Fe(551.2) , Cu(l 08.2) , Zn(86.4) , Cr(80.2) , respectively]. Whereas, the content of heavy metals expect for Mn, Cu was lowest at Yeungchun Dam [Cd(0.40), Fe(548.0), Zn(30.7), Cr(6.2). respectively] Also, the content of Cr, Zn was increased when the sampling areas are changed from upstream to downstream except for Hayang Bridge, and Hayang Bridge was the diverging point of the heavy metals eontent. 2. There were relatively correlated between Mn:FE, Cu, Zn, Cr, Fe Cu, Zn, Cr (0.40 < I rI < 0.70), and were high correlated between Cd Mn, Fe, Cu. Zn, Cu Zn, Zn Cr(0.70 < Ir I < 0.90). Particularly, there was higest correlated between Cd Cr. Cu Cr(0.90 < I rI < 1.0)
