Migration levels of plasticizers, di-n-butyl phthalate (DBP), benzyl-butyl phthalate (BBP), di-n- octyl phthalate (DNOP), di-iso-decyl phthalate (DIDP) and di-iso-nonyl phthalate (DINP), di-(2-ethylhexyl) adipate (DEHA), from 46 poly(vinyl chloride) (PVC) wrap films and 54 PVC gaskets into food simulants were determined using gas chromatography/ mass spectrometry (GC/MS). The method was validated with limit of detection (LOD) of 0.01 ~ 0.02 μg/mL for DBP, BBP, DNOP and DEHA, and 2 μg/mL for DIDP and DINP. The linearity were found to be > 0.99 for all the compounds in concentration range of 0.1 ~ 81.4 μg/mL, and overall recoveries were ranged from 90.4 ~ 99.6%. DBP, BBP, DNOP, DEHA, DIDP and DINP were not detected in food simulants, except 1 wrap sample from which 0.28 and 0.99 μg/mL of DEHA were detected respectively when tested with 20% ethanol and n-heptane as food simulants. These values were below the regulatory limitation in European Union (EU).
