Sixty-nine compounds were identified, including several additives used in PE synthesis such as alkanes, alkenes, antioxidants and plasticizers as well as non-intentionally added substances (NIAS) like degradation products such as 2,6-di-tert-butyl-1,4-benzoquinone, 2,4-di-tert-butylphenol, phenol, 2,5-bis(1,1-dimethylethyl)-, 3,5-di-tert-butyl-4-hydroxybenzaldehyde, and 3,5-di-tert-butyl-4-hydroxyacetophenone, or various residues from flavoring agents, cleaning products and essential oils. Some of these compounds as the isomers p and o t-butylcyclohexyl acetate, 3-Octanol, 3,7-dimethyl- and thujanol acetate (3-) pose a potential risk to children, as their concentrations exceed the recommended Cramer values for high percentages of recycling. This suggests improving recycling processes by incorporating advanced cleaning to remove residual products and contaminants. 000136449 536__ $$9info:eu-repo/grantAgreement/ES/MCIN/RYC2021-034150-I$$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-123742OB-I00 000136449 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000136449 590__ $$a11.3$$b2024 000136449 592__ $$a3.078$$b2024 000136449 591__ $$aENVIRONMENTAL SCIENCES$$b19 / 374 = 0.051$$c2024$$dQ1$$eT1 000136449 593__ $$aEnvironmental Chemistry$$c2024$$dQ1 000136449 591__ $$aENGINEERING, ENVIRONMENTAL$$b5 / 83 = 0.06$$c2024$$dQ1$$eT1 000136449 593__ $$aEnvironmental Engineering$$c2024$$dQ1 000136449 593__ $$aWaste Management and Disposal$$c2024$$dQ1 000136449 593__ $$aPollution$$c2024$$dQ1 000136449 593__ $$aHealth, Toxicology and Mutagenesis$$c2024$$dQ1 000136449 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000136449 700__ $$0(orcid)0000-0003-2638-9221$$aCanellas, Elena$$uUniversidad de Zaragoza 000136449 700__ $$0(orcid)0000-0003-2685-5739$$aNerín, Cristina$$uUniversidad de Zaragoza 000136449 7102_ $$12009$$2750$$aUniversidad de Zaragoza$$bDpto.
