Dissolved and suspended particulate adsorbed chlorobenzene (CB) concentrations were surveyed in Ise Bay, Japan. A plume with high concentrations of dissolved dichlorobenzenes, trichlorobenzenes, and tetra-chlorobenzenes was found in the surface layer from Yokkaichi Port to the border of the city Tokoname, indicating that these chemicals from Yokkaichi petrochemical complexes were transported by the flow caused by the Kiso River. Higher log values for the organic carbon-based partition coefficient (log Koc) were observed just outside this plume. A possible explanation for this phenomena is the combination of rapid decrease of the dissolved concentration due to convection and the slow desorption of adsorbed CBs from suspended particulates outside the plume. In spite of the relatively large site-dependent variation of log Koc in the bay, the log Koc values averaged over the bay for each CB isomer correlated with the octanol/water partition coefficient (log Kow) reported for these compounds. This showed that the chemical properties of the compounds, as reflected in the log Kow, was the major controlling factor for the log Koc in the field, despite the observed site-dependent variation in log Koc. |
