Abstract: Laboratory studies and model simulations were conducted to investigate and predict desorption kinetics for several polycyclic aromatic hydrocarbons and polychlorinated biphenyl 153. Desorption kinetics were biphasic, consisting of a rapid phase followed by gradual changes. Most of the changes (in percent of steady-state) occurred within the first few hours of incubation. Desorption partition coefficient (K𝚍) values indicated that desorption was minor. Model simulations were compared with laboratory experimental data to evaluate the accuracy and the applicability of the RECOVERY model in predicting desorption kinetics. For the most part, model simulations provided a reasonably good fit to the experimental data with few exceptions. In situations where the model did not accurately estimate desorption values, it predicted trends similar to those observed in laboratory experimental data.
