title: A model for predicting sediment-water partition of toxic chemicals in aquatic environments.
abstract: In order to investigate the characteristics of sediment-water partition of chemicals in aquatic environments using published data, we developed a model for predicting the sediment-water partition coefficient (Kp) as the sum of sorption to sediment organic matter and sorption to sediment inorganic matter. This model is so successful that the differences between Kp (median for a variety of Japanese water bodies) and pre-Kp (predicted K) are within one order of magnitude in 24 out of 28 chemicals.
