【摘要】 目的应用顶空气相色谱-质谱法,检测婴幼儿食品呋喃含量,计算相关的暴露量。方法采用顶空GC-MS方法检测北京市场上购买的4类婴幼儿食品,并应用检测结果计算相关的的呋喃的暴露量。结果婴幼儿食品呋喃含量平均值:奶粉为17.44μg/kg,米粉为16.41μg/kg,泥状食品为25.73μg/kg,果汁未检出;摄入这些食品造成的平均暴露量为1.533～5.985μg/d,约合0.341～0.712μg/(kg bw·d)。范围最高为0.521～2.474μg/(kg bw·d),最低为0.129～0.491μg/(kg bw·d)。结论北京市售婴幼儿食品中含有较高浓度的呋喃,在配方奶粉和辅食中均含有呋喃。推广母乳喂养,建立婴幼儿食品中呋喃的限量标准是降低呋喃暴露量的主要方法。更多还原

【Abstract】 Objective A study of contaminative status and relative exposure estimation was performed to get the furan intake in the Beijing infant food.Mefliods 4 separate items bought in the Beijing market were analyzed and relative exposure was calculated.Results The following were mean levels of furan of each items:infant formula milk powder 17.44μg/kg,infant formula rice powder 16.41μg/kg,commercial baby food in glass jars 25.73Ng/kg,fruit juices undetectable,which leads exposure of different ages from 1.533 to 5.985μg/d,0.341 - 0.712μg/(kg bw·d).With the highest concentration of each type of each stage,the exposure of different ages was 0.521- 2.474μg/(kg bw·d). Conclusion The survey leads to the conclusion that infant food sold in Beijing was contaminated with high concentration of furan,which leads to high exposure of infant or baby.更多还原
