Abstract
    Polydimethylsiloxane sheets were used to determine freely dissolved concentrations (Cdiss) of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in the Belgian coastal zone. Equilibrium models were used to predict the whole water concentrations (Cww) of these compounds as well as their concentrations in sediment, suspended particulate matter (SPM) and biota. In general, contaminant concentrations were predicted well for whole water and biota. Cww was increasingly underpredicted as Koc increased, possibly because of the presence of black carbon. Concentrations in biota were overestimated by the equilibrium approach when log Kow exceeded 6.5, suggesting an increasing role of transformation processes. Concentrations of PAHs and PCBs in sediment and SPM were consistently underpredicted although a good correlation between measured and predicted values was observed. This was potentially due to the use of experimental Koc values which have been found to underestimate partitioning of hydrophobic substances to sediment in field studies.
