  13. In order to develop a mnumerical model estimating the behavior of discharged pollutants to coastal environment, we survayed distributions and behaviors of chlrobenzens and butyltins in Ise Bay. Their distribution patterns in the surface sediment were explained by the following effects: the distance from the source, the horizontal transport caused by the river inflows, and the sedimentation caused by downward water flow. The transportation of the pollutants from surface water to bottom sediment was explained by the process of their absorption to suspended matter and their settling on suspended matter.
