Journal ArticleDOI
Bioavailability of Hydrophobic Organic Contaminants: Effects and Implications of Sorption‐Related Mass Transfer on Bioremediation
TL;DR: The influence of sorption on biodegradation is quantified here by defining a bioavailability factor, Bf, and challenges facing environmental engineers are to develop a better understanding of these processes at both laboratory and field scales.
Journal ArticleDOI
Biodegradation of benzene, toluene and naphthalene in soil-water slurry microcosms
Wei-xian Zhang,Edward J. Bouwer +1 more
TL;DR: Aerobic biodegradation of benzene, toluene and naphthalene was studied in pre-equilibrated soil-waterslurry microcosms.
Journal ArticleDOI
Biotransformation of aromatic hydrocarbons in subsurface biofilms
TL;DR: In this article, the importance of bioavailability on the performance of in situ bioremediation is discussed by using aromatic hydrocarbons as model contaminants, and the application of biofilm kinetics toward this goal is addressed.
Journal ArticleDOI
Biotreatment of PAH-contaminated Soils/Sedimentsa
TL;DR: A mass transfer-limited numerical model was developed to explore the effect of sorption and bioavailability on biodegradation rates and it is indicated that sorption may have also significantly affected biodegrading rates by limiting the bioavailability of the aromatic compounds.
Book ChapterDOI
Biodegradation of Coal Tar Constituents in Aquifer Sediments
TL;DR: It is important to establish the appropriate chemical conditions required for biodegradation of the contaminants and to assess the relative importance of mass transfer versus kinetic effects in in situ bioremediation.
