[Determination of volatile substances and leachable components in polystyrene food contact wares].
Material and migration tests of food-contact plastic wares made of polystyrene were carried out. The average concentration of volatile substances (sum of toluene, ethylbenzene, isopropylbenzene, n -propylbenzene, and styrene) in materials was 861 +/- 692 ppm. Styrene was observed in 95% of 19 samples. alpha-Methylstyrene, which is one of the material compounds of polystyrene, was detected in one sample. Release of volatile substances into n-heptane was not observed at the detection limits of 0.1 ppm.
