This International Standard specifies the quantitative determination of 16 PAH (see Table 2) insludge, soil, and treated biowaste using GC-MS and HPLC-UV-DAD/FLD covering a wide range of PAHcontamination levels (see also Annex B).When using fluorescence detection, acenaphthylene cannot be measured. The limit of detection depends on the determinants, the equipment used, the quality of chemicals usedfor the extraction of the sample, and the clean-up of the extract.Typically, a lower limit of application of 0,01 mg/kg (expressed as dry matter) can be ensured for eachindividual PAH. This depends on instrument and sample. Sludge, soil, and treated biowaste can differ in properties and also in the expected contamination levelsof PAH and presence of interfering substances. These differences make it impossible to describe onegeneral procedure. This International Standard contains decision tables based on the properties ofthe sample and the extraction and clean-up procedure to be used. Two general lines are followed, anagitation procedure (shaking) or use of Soxhlet/pressurized liquid extraction.
