北京市售婴幼儿食品中呋喃污染状况及相关暴露量的现况研究

Contamination status and relatively exposure of furan on Beijing infant food

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/（kgbw.d）。范围最高为0.521-2.474μg/（kgbw.d）,最低为0.129-0.491μg/（kgbw.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。

Objective A study of contaminative status and relative exposure estimation was performed to get the furau 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 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. 73μg/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.
