Abstract
The sediment‐water partition coefficients of 18 polychlorinated biphenyl (PCB) congeners were determined for three marine sediment samples. The partition coefficients increased with the hydrophobicity of the PCBs and with the organic carbon content of the sediments. High correlations were obtained by multiple regression analysis with different models using the partition coefficients and the solubilities, octanol‐water partition coefficients, total molecular surface areas and molecular connectivity indices of the PCBs and the organic carbon content of the sediments.
