Polycyclic aromatic hydrocarbons (PAHs) including phenathrene, fluoranthene, and pyrene in sediment were extracted with aqueous micellar solutions of anionic surfactants. The surfactants examined were sodium dodecyl sulfate, sodium oleate, and sodium di(2-ethylhexyl) sulfosuccinate. The extraction yields of PAHs increased with increasing the surfactant concentration and the extraction time. They reached constant values (ca. 30%), which agreed with results obtained by the 1-butanol extraction method. The present results suggest the usefulness of surfactant-based extraction for evaluating the bioavailability of organic pollutants in sediments.
