摘要：

A simple sequential extraction technique is presented for the examination of PAH speciation in aquatic sediments. This method is discussed with special emphasis on the sorption of PAH to humic substances and coal-like particles. Sorption experiments were carried out with sediments after treatment with H2O2 or after lipid removal by organic solvent extraction. The results show that lipids exert only a minor influence on PAH sorption. Furthermore, deviations from simple partition behaviour an discussed.
