Resumen: This document specifies different methods for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 1) in compost or digestate, using GC-MS, GCMS/MS or HPLC UV DAD/FLD covering a wide range of PAH contamination levels (see Table 1). When using fluorescence detection, acenaphthylene cannot be measured. Table 1 — Target analytes of this document Target analyte CAS-RNa Naphthalene 91–20–3 Acenaphthene 83–32–9 Acenaphthylene 208–96–8 Fluorene 86–73–7 Anthracene 120–12–7 Phenanthrene 85–01–8 Fluoranthene 206–44–0 Pyrene 129–00–0 Benz[a]anthracene 56–55–3 Chrysene 218–01–9 Benzo[b]fluoranthene 205–99–2 Benzo[k]fluoranthene 207–08–9 Benzo[a]pyrene 50–32–8 Indeno[1,2,3-cd]pyrene 193–39–5 Dibenz[a,h]anthracene 53–70–3 Benzo[ghi]perylene 191–24–2 a CAS-RN Chemical Abstracts Service Registry Number. The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. The method may be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.
