Abstract
A simple, accurate and sensitive gas-liquid chromatographic method has been developed for the determination of styrene migrating from polyst yrene containers into foodstuffs. An apparatus for the extraction of s tyrene was designed for the purpose, based on the BP apparatus for the determination of volatile oils. Styrene was extracted from foods by d istillation with concurrent extraction from the distillate by n-hexane . Extraction was complete in 35 min. Hexane extracts were analysed by GC-FID using a glass column with durene as internal standard. Styrene levels in containers were from 1.7 to 192 mu g g(-1) and in foods from 0.013 to 0.13 mu g g(-1).
