Sediment Control of Facilitated Transport and Enhanced Desorption
Publication: Journal of Environmental Engineering

Abstract
Laboratory column experiments examined the facilitated transport and enhanced desorption of benz(a)anthracene [B(a)A] by dissolved natural organic matter (OM) in sediments of low organic carbon content. The two-component experiments examining OM-sediment interaction and B(a)A-sediment interaction were modeled to determine the value of the linear rate constants describing transfer of B(a)A and OM between water and sediment. It was found that a two-rate approach better simulated B(a)A breakthrough and elution in the sediment relative to a one-rate approach. In contrast, OM-sediment interaction was well-simulated with a one-rate approach due to low OM sorption by sediment. The three-component experiments examining facilitated transport and enhanced desorption of B(a)A by dissolved OM, showed rapid linear reversible B(a)A-OM interaction. The value, within a factor of 2, of the equilibrium distribution constant for benz(a)anthracene distribution between water and OM was ∼1E6 for soil humic acid and ∼1E5 for Suwannee River humic acid. Simulations of the three-component experiments based on the equilibrium distribution constants for B(a)A-OM interaction and the rate constants determined from the two-component experiments were performed to determine whether rate constants differed in the two-component versus three-component systems. The simulations captured the major features of the facilitated transport and enhanced desorption data; however, discrepancies indicated that either the two-rate model for solute-sediment interaction was inappropriate, or that B(a)A transfer from sediment to dissolved OM was altered in the three-component system relative to the two-component system.
