The purpose of this study is to investigate on the water quality of the upper region of Wonchun stream located in Suwon city by chemical analysis and EROD-microbioassay methods using rat hepatoma cell line H4ⅡE. The water samples were collected at 6 sampling sites from Sept. to Nov. 1999 and determined the quantitative toxic effects. Higher levels of BOD_5, COD_Cr, and COD_Mn, were determined at M6 site where the influent contains domestic and industrial wastewater. EROD activity of water samples was ranged from 3.43±0.08 to 9.05±0.10 pmol/mg protein/min. High correlation with EROD activities and COD values was observed. From the results, the upper region of Wonchun stream water area was presumed to be highly polluted with various persistent organic chemicals.
