Abstract
After oil pollution events, oil components as PAH may affect biota of near-coastal
sediments for extended time periods, and bioturbation by infaunal organisms may
affect the fate of PAHs. Modelling of bioavailability of hydrophobic sediment
pollutants to aquatic organisms generally assumes that diffusion from water
dominate uptake. This is, however, not necessarily true for sediment ingesting
infauna. The lugworm Arenicola marina and [^C-4,5,9,10] pyrene were used in
experimental benthic microcosms to study infaunal interactions in distribution and
metabolism of the PAH fraction of oil and allow quantification of pyrene and its
metabolites including ^CC^, in interstitial and overlying water, sediment and
worms. Manipulation of the sedi
