Abstract

The levels of butyltin compounds in poly(vinyl chloride) (PVC) food packaging using gas chromatography/mass spectrometry (GC/MS) were monitored. The analytical method, involving the ethylation with sodium tetraethylborate, was found to be selective and sensitive for mono-n-butyltin (MBT), di-n-butyltin (DBT), and tri-n-butyltin (TBT), validated by a $0.005\;{\mu}g/mL$ limit of detection (LOD), an $R^2>0.999$ for linearity, and >90% of recovery, respectively. Finally, none of the commercial food wraps and gaskets showed detectable levels of butyltin compounds.

국내 유통되는 PVC제 랩 3건 및 병마개 가스킷 26종에 대한 부틸주석화합물의 재질 중 잔류량을 조사하였다. Mono-n-butyltin(MBI), di-n-butyltin(DBT) 및 tri-n-nutyltin(TBT)에 대하여 sodium tetraethylborate로 ethylation 유도체화 후 GC/MS-SIM으로 분석하였다. 분석법 검증결과 본 연구에서 사용한 분석방법의 검출한계는 $0.005\;{\mu}g/mL$였으며, $0.02-3.13\;{\mu}g/mL$의 농도범위에서 $R^2$ 값이 0.999 이상의 직선성, 90% 이상의 회수율을 확인할 수 있었다. 총 29건의 시료에 대하여 분석한 결과 모든 시료에서 부틸주석 화합물은 검출되지 않았다.
