[Contamination status and relatively exposure of furan on Beijing infant food].

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 were mean levels of furan of each items: infant formula milk powder 17.44 microg/kg, infant formula rice powder 16.41 microg/kg, commercial baby food in glass jars 25.73 microg/kg, fruit juices undetectable, which leads exposure of different ages from 1.533 to 5.985 microg/d, 0.341-0.712 microg/(kg bw x d). With the highest concentration of each type of each stage, the exposure of different ages was 0.521-2.474 microg/(kg bw x 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.
