A Study on Residual Amounts of Vinyl Chloride/Vinylidene Chloride in Poly(vinyl chloride)/Poly(vinylidene chloride) Food Packaging usingHeadspace GC/MS

摘要

Vinyl chloride (VC) and vinylidene chloride (VDC), which may be present in poly(vinyl chloride) (PVC) and poly(vinyUdene chloride) (PVDC) food packaging, were analyzed by using a headspace-gas chromatograph (GC)/mass spectrometer (MS) equipped with aPLOT Q column. 1-Chloropropane (1-CP) was used as an intemal standard. The determinations of VC and VDC were carried out by monitoring the characteristic ions for each compound: m/z=61, 62, 64 and m/z=61, 96, 98, respectively. The method vahdated in thisstudy can be suitable for the compliance test of EU regulation. Among 103 food packaging samples, VC and VDC were not detected, except in one PVDC food package. However, the detected level of VDC in the sample was below the EU regulatory specific limitation.
