Development of a kinetic basis for bioavailability of sorbed naphthalene in soil slurries

摘要

The degradation of naphthalene in soil-slurry systems was studied using four different organisms and two soils. Organisms with zero-order, first-order, and Michaelis-Menten rates were selected. The soils had substantially different Sorption distribution coefficients. Sorption and desorption was evaluated in abiotic soil-slurry systems. The desorption Process was described by a model that accounts for equilibrium, rate-limited and non-desorbing sites. Biodegradation Parameters were measured in soil-extract solutions.
