Migration of styrene monomer from polystyrene (PS) dishes were conducted during this research at
temperatures of 5, 20, and 40 0C. According to the Food and Drug Administration (FDA) regulations, these
experiments were performed in contact with 10%ethanol as a food simulant for the oil in water (o/w) emulsions. The
dishes were filled in each defined temperatures and stored for 35 days. In a relatively close intervals (1, 7, 15, 24, and
35 days) the amount of migration which occured, was determined by means of Head Space Gas Chromatography Mass
Spectrometry (HS-GC-MS). By increasing storage time and temperature, the amount of migration was increased and in
all times and temperatures styrene monomer was detected. In addition, a mathematical model based on the Fick’s
second law was validated to predict migration from packaging material into the 10% ethanol. The resulted diffusion
coefficients were 3.6*10-18 , 4.9*10-18, and 6*10-18 (m2/s) in 5 ,20 and 40 0C respectively.
