The sediment-water partition
coefficients of 18 polychlorinated biphenyl (PCB) congeners were determined for
marine sediments whose organic matter had been oxidatively removed. The results
were compared with those previously determined for the same but untreated
sediments. The removal of organic matter resulted in a decrease of the
partition coefficients, more marked for those congeners with a relative lower degree
of chlorination. The sorption of PCBs on the mineral particles whose organic matter
has been removed becomes increasingly significant as the hydrophobicity of the PCBs
and the percentage of silt-clay fraction of the sediments increase.
