Abstract: This study was conducted to do exposure assessment of the possible migration of antimony trioxide (Sb2O3) from Polyethylene terephthalate (PET) food contact materials (FCM). Consumption Factor (CF) and Food-type Distribution Factor (fT) were calculated from survey data with reference to the US FDA method. The most conservative migration conditions were obtained by testing Sb migration from PET FCM based on the Chinese national standard of GB/T 5009.101-2003[1]. Migration levels of Sb from PET FCM were tested and migration levels of Sb2O3 were obtained through molecular weight conversion between Sb and Sb2O3. Exposure assessment of Sb2O3 was undertaken. The Chinese Estimated Daily Intake (EDI) of Sb2O3 resulted from PET FCM was 90.7 ng p-1d-1.
