The concentration range studied was 0.1–7.5 µg g−1 with R2 higher than 0.9963, intraday RSD values below 5 %, RSD values between days lower than 12 %, recoveries higher than 80 %, LOD and LOQ lower than 0.09 μg g−1. Ten of the target analytes were identified in offset printing inks at concentrations between 2.28 and 8.59 µg g−1. Nine of them were also identified in the food packages examined in concentrations ranging from 0.10 to 0.33 µg g−1. These compounds were: methylnaphthalene, 2-methylnaphthalene, biphenyl, 2,6-dimethylnaphthalene, acenaphthene, 3,3′,5,5′-tetramethylbiphenyl, 4,6-dimethyldibenzothiophene, 1-methylpyrene, benzo(b)naphtha(1,2-d)thiophene and 9,9′-dimethylfluorene. Mineral oil in food packaging was previously analysed by GC with flame ionization detection (FID). info:eu-repo/grantAgreement/ES/DGA-FEDER/T53-20R info:eu-repo/grantAgreement/ES/MICINN/RTI2018-097805-B-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 8.8 2022 CHEMISTRY, APPLIED 5 / 72 = 0.069 2022 Q1 T1 NUTRITION & DIETETICS 5 / 87 = 0.057 2022 Q1 T1 FOOD SCIENCE & TECHNOLOGY 9 / 142 = 0.063 2022 Q1 T1 1.624 2022 Analytical Chemistry 2022 Q1 Medicine (miscellaneous) 2022 Q1 Food Science 2022 Q1 14.9 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Domeño, Celia Universidad de Zaragoza (orcid)0000-0001-8893-0963 Nerín, Cristina Universidad de Zaragoza (orcid)0000-0003-2685-5739 2009 750 Universidad de Zaragoza Dpto.
