Soot is mainly formed from polycyclic aromatic hydrocarbons (PAH), through different reaction ways and, once formed, it can adsorb PAH on its surface. These compounds have an environmental importance due to their carcinogenic and mutagenic potential. In the last years, the oxygenated derivatives of PAH (oxy-PAH) have also been considered as dangerous since they have been found to be mutagenic for bacterial and human cells. Therefore, the purpose of this work was to quantify simultaneously selected PAH and oxy-PAH from different samples of soot. The quantification method involves Soxhlet extraction and subsequent concentration by rotary evaporation that allows to recover the analysed compounds from soot samples. The PAH and oxy-PAH were identified and quantified, by a single injection, using a gas chromatograph-mass spectrometer (GC-MS). The method showed a good repeatability using a diesel soot surrogate test sample, Printex-U. The validation process showed that most of the compounds are recovered between the values established for the Standard Reference Materials analysed, 1650b and 1649b. The values of the mass fraction of the oxy-PAH obtained in this work showed, in general, a good match with those indicated in other studies. info:eu-repo/grantAgreement/ES/DGA-FEDER/T22-17R info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-65226 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.731 2021 ENVIRONMENTAL SCIENCES 192 / 279 = 0.688 2021 Q3 T3 CHEMISTRY, ANALYTICAL 50 / 87 = 0.575 2021 Q3 T2 0.329 2021 Analytical Chemistry 2021 Q3 Health, Toxicology and Mutagenesis 2021 Q3 Water Science and Technology 2021 Q3 Soil Science 2021 Q3 Waste Management and Disposal 2021 Q3 Pollution 2021 Q3 3.2 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Pezo Piña, Davinson (orcid)0000-0002-1569-7256 Millera, Ángela Universidad de Zaragoza (orcid)0000-0001-5426-6486 Bilbao, Rafael Universidad de Zaragoza (orcid)0000-0002-5420-0943 Alzueta, María Uxue Universidad de Zaragoza (orcid)0000-0003-4679-5761 5005 555 Universidad de Zaragoza Dpto.
