In experimental microcosms, an investigation on the sediment-to-air fluxes of two PAH, phenanthrene and pyrene, and a heterocyclic aromatic hydrocarbon, dibenzofuran, from a laboratory-contaminated sediment and three PAH (naphthalene, phenanthrene, and pyrene) from three bed-sediment field sites, showed that the flux was dependent on the sediment moisture content, air-filled porosity, and the relative humidity of the air flowing over sediment surface. Observed values were in excellent agreement with the mathematical model predictions of flux from laboratory spiked sediment.
