The levels and seasonal variation of 19 volatile organic compounds (VOCs) in Ise Bay inner coastal area and rivers pour into the bay were studied. In coastal marine, chloroform, bromoform, p-dichlorobenzen and dichloromethane were detected at high concentrations, and in rivers, 1, 1, 1-trichloethane, chloroform, dichloromethane, cis-1, 2-dichloroethylene, o-xylene, trichloroethylene and p-dichlorobenzen were detected at high concentrations. Especially, wide distributions of chloroform in both waters and bromoform in sea were outstanding. The concentration of many chlorinated VOCs showed winter maxima, but with regarding to flowing amounts instead of concentrations, urban rivers receiving domestic and industrial discharge showed summer maxima. Many VOCs components had correlation with each other and with water pollution indicators (BOD, COD, SS, T-N), but 1, 2-dichloroethane and bromoform had low correlation with other chlorinated VOCs or water pollution indicators. Seasonal variations of VOCs observed were thought to be suggesting their plausible origins.
