Abstract
|
|
|
|
Concentrations of PCBs in the sediment of the Kumho River was determined. Samples were collected at 23 locations along the river. Total PCB levels ranged from 2.7 to 87.6 ng/g dry weight. The site near the Keomdan factory district had the highest concentrations. The levels of PCB congeners significantly correlated with the total organic carbons in the sediment. The major fractions of PCBs were congeners containing 4, 5, or 6 chlorine atoms per biphenyl molecule.
