Laboratory studies have shown that speciation of hydrophobic organic pollutants in aquatic systems is too complex to model as a linear, two-phase sorption equilibrium due to ill-defined phases and slow kinetics. This complexity is manifested in an inverse variation in sediment-water partition coefficients with the concentration of solids. Measurements of the sediment-water partitioning of polychlorobiphenyl (PCB) congeners in Lake Superior provide some of the first field evidence demonstrating the importance of colloids to the fates of highly hydrophobic organic pollutants.
