Chromatographic determination of polycyclic aromatic hydrocarbons [PAH] in sewage sludge, soil, and sewage sludge-amended soils

An effective method for determining polycyclic aromatic hydrocarbons in soils fertilised with sewage sludge is presented in this paper. PAH extraction was carried out by ultrasound; dichloromethane was used as a solvent. Purification was done by means of solid phase extraction. Identification and determination was carried out by means of HPLC with a UV detector. The present analyses were carried out on the soil (control), sewage sludge, and soil fertilised with sewage sludge at a rate of 1, 2.5, 5, 10, and 20%.
