Linking desorption kinetics to phenanthrene biodegradation in soil.
Abstract
The desorption of polycyclic aromatic hydrocarbons (PAHs) often exhibits a biphasic profile similar to that observed for biodegradation whereby an initial rapid phase of degradation or desorption is followed by a phase of much slower transformation or release. Most investigations to-date have utilised a polymeric sorbent, such as Tenax, to characterise desorption, which is methodologically unsuitable for the analysis of soil. In this study, desorption kinetics of 14C-phenanthrene were measured by consecutive extraction using aqueous solutions of hydroxypropyl-β-cyclodextrin (HPCD). The data indicate that the fraction extracted after 24 h generally approximated the linearly sorbed, rapidly desorbing fraction (Frap), calculated using a three-compartment model. A good linear correlation between phenanthrene mineralised and Frap was observed (r2 = 0.89; gradient = 0.85; intercept = 8.20). Hence HPCD extraction (24 h) and first-order three-compartment modelling appear to provide an operationally straightforward tool for estimating mass-transfer limited biodegradation in soil. Aqueous hydroxypropyl-β-cyclodextrin (HPCD) solutions can predict the rapidly desorbing and microbially degradable fractions of phenanthrene in soils.
