ABSTRACT
This research studies the relation between mobility and dynamic bioavailability of organic contaminants. Dynamic bioavailability is here expressed as a mass bioavailability rate. A model case study was carried out using saturated laboratory columns of either inert or sorptive materials towards the target contaminant, pentachlorophenol. Contaminant specific degrading microorganisms were inoculated in the columns and acted as biological receptor to measure bioavailability. Results show that, despite the contaminant capacity to migrate through the sorptive column, dynamic bioavailability was reduced from 13% to 0.5% of its maximum value.
