The diffusion coefficient and partition coefficient of hexachlorobiphenyl (HCBP) in a sediment are determined by using a dual radio-tag experiment that extended over 2 years. Essentially constant coefficients were observed. An independent measurement of the diffusion coefficient for a nonsorbing chemical (tritiated water) allows an estimate to be made of the interstitial water-sediment partition coefficient. The result is in close agreement with that predicted from hydrophobic sorption correlations based upon sediment organic carbon and HCBP octanol-water partition coefficient. It also corresponds to the low particle concentration limit of the partition coefficients found when batch equilibrations of dilute suspensions of the same sediment were used.
