Volatile organic compounds (VOCs) were analyzed on the seawater from 17 stations in Kwangyang Bay throughtout the year. We could not detect 10 VOCs; methylene chloride, tetrachloromethane, 1, 1, 1-trichloroethane, trichloroethane, 1, 1, 1, 2-tetrachloroethane, trichloroethylene, bromoethane, dibromoethane, bromobenzene, 1-ethyl-3-methylbenzene. The other VOCs-chloroform, 1, 2-dichloroethane, ethylbenzene, benzene, toluene, m, p-xylene, methylethylketone, styrene, hexane-were detected with a little variance according to the sampling stations and the sampling seasons. The concentrations of chloroform (0.6 ~ 49.9 $mu$g/1) and toluene (0.42 ~ 48.3 $mu$g/1) were high and they were detected more frequently than the other detected VOCs. We also tried to seek the correlation between the physicochemical environmental factors and VOCs. Only toluene had the high correlation coefficient with the water temperature (r = -0.524) and with the pH (r = 0.319). Correlation between VOCs themselves showed some interesting results. The benzene had high correlation coefficient (r = 0.549 ~ 0.662) with three VOCs such as toluene, m, p-xylene, ethylbenzene. From these results it is suggested that VOCs might be discharged simultaneously in Kwangyang Bay.
