Different types of polystyrene packaging material were tested for styrene monomer migration into corn oil using three sampling methods: immersion sampling, vapour phase sampling and utilization of sampling cells. For high‐impact‐grade polystyrene, immersion sampling resulted in the highest level of migrated styrene monomer. Vapour phase sampling was of considerable interest, because migration was only slightly lower than with immersion sampling. Sampling cells gave the lowest levels of styrene monomer in oil. However, when clear crystal polystyrene was tested, little difference was found between the three sampling methods.
