The research of PAH leaching was conducted within a simulated period of 24 months, with the examination of PAH washing out every three months. The highest amounts of PAH (297 - 330 μg/kg dw.) were obtained_from granulates containing 7 parts by weights of sewage sludge (3 times higher in comparison with the granulate containing ash and sludge in ratio of I: 1 ). The maximum PAH release from all the examined granulates took place in the 9th month of the research. Benzo(k)fluoranthene revealed the highest fraction (67.4-76.0%) of all examined compounds.}, type={Article}, title={Leaching of PAHs from Fly Ash - Sludge Blends}, URL={http://www.czasopisma.pan.pl/Content/123104/PDF/7_AE_VOL_34_3_2008_Rosik_Dulewska_Leaching.pdf}, keywords={ash, sewage sludge, PAH, leaching}, }
