摘要：目的 應用頂空氣相色譜質(zhì)譜法，檢測嬰幼兒食品呋喃含量，計算相關(guān)的暴露量。方法 采用頂空GC-MS 方法檢測北京市場(chǎng)上購買(mǎi)的4類(lèi)嬰幼兒食品，并應用檢測結果計算相關(guān)的的呋喃的暴露量。結果 嬰幼兒食品呋喃含量平均值，奶粉為17.44μg/kg，米粉為16.41μg/kg，泥狀食品為25.73μg/kg，果汁未檢出；攝入這些食品造成的平均暴露量為1.533～5.985μg/d，約合0.341~0.712μg/(kg bw∙d)。范圍：最高為0.521~2.474μg/(kg bw∙day)，最低為0.129~0.491μg/(kg bw∙d)。結論 北京市售嬰幼兒食品中含有較高濃度的呋喃，在配方奶粉和輔食中均含有呋喃。推廣母乳喂養，建立嬰幼兒食品中呋喃的限量標準是降低呋喃暴露量的主要方法。

Abstract: Objective  A study of contaminative status and relative exposure estimation was performed to get the furan intake in the Beijing infant food.  Methods  4 separate items bought in the Beijing Market were analyzed and relative exposure was calculated. Results  The following are 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 25.73μg/kg，fruit juices undetectable, which leads exposure of different ages from 1.533 to 5.985μg/day, 0.341-0.712μg/(kg bw∙day). With highest concentration of each type of each stage, the exposure of different ages was 0.521-2.474μg/(kg bw∙day). 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.
