An　RP　LC-ESI-MS/MS　method　for　the　determination　of　the　migration　of　16　primary　phthalic　acid　esters　from　plastic　samples　has　been　developed　using　distilled　water,　3%　acetic　acid,　10%　alcohol,　and　olive　oil　as　food　simulants.　Detection　limits　were　1.6-18.5　mu　g/kg　in　distilled　water,　1.4-17.3　mu　g/kg　in　3%　acetic　acid,　1.4-19.2　mu　g/kg　in　10%　alcohol,　and　31.9-390.8　mu　g/kg　in　olive　oil.　The　RSDs　were　in　the　range　of　0.07-11.28%.　The　real　plastic　products　inspection　showed　that　only　few　analyzed　samples　were　phthalates　contaminated.　Bis-2-ethylhexyl　ester　and　dibutyl　phthalate　were　the　common　items　migrated　from　the　plastic　products　into　food　and　feeds,　but　the　migration　concentrations　were　far　below　the　limits　set　by　European　Union　(1.5　mg/kg　for　bis-2-ethylhexyl　ester　and　0.3　mg/kg　for　dibutyl　phthalate).
