摘　　要：目的对中国市售食品接触硅橡胶制品(Food Contact Silicone Rubber Products,FCSRPs)中的邻苯二甲酸酯类(Phthalate Acid Esters,PAEs)塑化剂以及其向冲调奶液中的迁移暴露进行研究,为FCSRPs的安全性研究提供理论支撑及科学依据。方法利用超声溶剂提取-气相色谱串联质谱(UASE-GC-MS/MS)方法检测中国市售32种FCSRPs中的16种PAEs,建立并利用QuEChERS-GC-MS/MS方法对硅橡胶奶杯中PAEs向冲调奶液中的迁移及安全性进行研究。结果32种FCSRPs中检出5种PAEs,不同样品间PAEs含量差异较大。5种PAEs对不同年龄段幼儿的EDI值均低于10μg/kg。本研究为FCSRPs及其他材质中PAEs研究提供了数据和理论支撑。结论硅橡胶制品中普遍检出PAEs,但婴幼儿通过使用硅橡胶奶杯进食冲调奶液而摄入的5种单一PAEs的暴露评估值低于限量值。The work aims to study the Phthalate Acid Esters(PAEs)plasticizer in food contact silicone rubber products(FCSRPs)marketed in China and their migration and exposure to the infant milk powder,to provide theoretical support and scientific basis for the safety study of FCSRPs.Sixteen PAEs in 32 FCSRPs marketed in China were detected by ultrasonic solvent extraction-gas chromatography-tandem mass spectrometry(UASE-GC-MS/MS).In particular,a QuEChERS-GC-MS/MS method was established and used to study the migration of PAEs in silicone rubber milk cups.Five PAEs(DBP,DIBP,DEHP,DEP,DMP)were detected in 32 FCSRPs,and the content of PAEs varied greatly among different samples.The EDI values of the five PAEs for children of different ages were all below 10μgkg^(-1)bw^(-1)day^(-1).This study provided data and theoretical support for the study of PAEs in FCSRPs and other materials.PAEs are generally detected in FCSRPs and the exposure values of five PAEs ingested by infants through using silicone rubber cups are below the limit value.
