Food contact materials (FCMs) have been reported as a source of various xenobiotics. This study investigates
the possibility of simultaneous analysis of 68 potential contaminants in paper FCMs, specifically
phthalates, polycyclic aromatic hydrocarbons, photoinitiators, bisphenols, and polyfluorinated
compounds. Target compounds were co-isolated using a technique based on ultrasonic extraction by
mixture of acetonitrile and water followed by QuEChERS-like liquideliquid partition in the presence of
inorganic salts. Resulting extracts were analyzed using gas and high performance liquid chromatography
coupled with tandem mass spectrometry (GCeMS/MS, HPLCeMS/MS). Acceptable recoveries (70e120%)
and RSDs (
