Effect of sorption on biodegradation of organic chemicals in soils



Effect of sorption on biodegradation of organic chemicals in soils



15th World Congress of Soil Science, Acapulco, Mexico, 10-16, July, 1994 Transactions, Volume 4a: commission III symposia: 352-361



The effect of soil sorption on the biodegradation of organic chemicals (pollutants) is described. Rates of biodegradation varied as a function of the chemical's diffusion coefficient, partition coefficient, and biodegradation rate constant. A mathematical model describing the biodegradation process in terms of chemical availability as affected by sorption and diffusion was developed with different kinetic expressions for reactions controlled by physical or by biological processes.
