초록

In this study, we investigated to measured concentration, seasonal characteristics and load quantity of volatile organic compounds(VOCs) for 11 sites in the main stream and 8 sites in the branch stream of Kumho river, during from October 1995 to April 1997. As a results, the small amount of volatile compounds, such as dichloromethane, chloroform, toluene, benzene, trichloroethene, tetrachloroethene, p-xylene and 1,3,5-trimethyl-benzene were detected from the main stream of Kumho river. Also detected to dichloromethene, chloroform, toluene, benzene, trichloroethene, tetrachloroethene, ethylbenzene, p-xylene, 1,3,5-trimethylbebzene and 1,2,4-trimethylbenzene in the branch stream, and dichloromerhane, chloroform and toluene were detected to all site of sampling. And seasonal variation of volatile organic compounds showed higher concentration in the July 1996 as a winter season than January 1997 as a summer season in most places. Also the load quantity of volatile organic compound at Gangchang site in the last downstream of Kumho river, was in order of chloroform > dichloromethane > toluene > trichloroethene.
