Abstract
The suspended sediment/water partition coefficients have been measured for 19 chlorinated organics in 25 samples from the St. Clair, Detroit and Niagara Rivers. An excellent linear correlation (r2 = 0.87) between the organic-carbon corrected partition coefficient (KOC) and the octanol/water partition coefficient (KOW) was found (log KOC = 0.76 log KOC + 1.66). Using this equation plus another equation developed in this paper it is shown that the percentage of chemical in the “dissolved” and “particulate” phases in the study rivers could be estimated from a chemical’s Kow to within a factor of two. The paper also discusses the time required for equilibrium to be achieved between the “dissolved” and “particulate” phases, and the potential importance of biota such as algae in the partitioning process.
