| Abstract: | The desorption behaviours of seven polynuclear aromatic hydrocarbons (PAHs) in contaminated coastal sediment have been studied under field. Total sedimentary concentrations of acenaphthene, benzo(a)anthracene, benzo(k)fluoranthene, benzo(a)pyrene, chrysene, fluoranthene and naphthalene were followed after the contaminated sediment samples had been translocated to a pristine coastal environment. The desorption kinetics of these PAHs were found to be describable by a two compartment model. The field desorption data were compared to other laboratory based sorption desorption kinetic data in the literature and were found to be in accordance with results obtained via mesocosm approach involving direct extraction of desorbed PAHs from the aqueous phase. However, when compared to results generated by conventional gas stripping desorption technique, the field desorption rates were at least an order of magnitude smaller. |
