采用超声波萃取-气质联用法测定食品包装用塑料垫圈中5种邻苯二甲酸酯（PAEs）的含量， PAEs添加回收率在83.9%~107.8%之间，标准偏差在1.5%~6.1%之间；此外，对其中包装容器内的食品也进行了检测。结果表明：GC-MS法可以对塑料垫圈中的邻苯二甲酸酯进行定性定量分析，样品垫圈均被检出含有PAEs增塑剂成分，且由于溶出迁移，对所接触的食品造成了不同程度的污染。
採用超聲波萃取-氣質聯用法測定食品包裝用塑料墊圈中5種鄰苯二甲痠酯（PAEs）的含量， PAEs添加迴收率在83.9%~107.8%之間，標準偏差在1.5%~6.1%之間；此外，對其中包裝容器內的食品也進行瞭檢測。結果錶明：GC-MS法可以對塑料墊圈中的鄰苯二甲痠酯進行定性定量分析，樣品墊圈均被檢齣含有PAEs增塑劑成分，且由于溶齣遷移，對所接觸的食品造成瞭不同程度的汙染。

Phthalate esters in plastic gasket used in food package was determinate by ultrasonic solvent extraction and gas chromatography-mass spectrometry (GC-MS). The recoveries of phthalate esters (PAEs) were from 83.9% to 107.8%, and RSD were from 1.5%to 6.1%. Results showed that PAEs in Plastic Gasket could be identified and quan-tified by GC-MS. PAEs Plasticizer were detected in the plastic gaskets, and the foods inside were also contaminated by PAEs because of the migration.
