中文摘要：0-6月婴儿的食物中除母乳外，其它膳食暴露风险很高。本研究针对坦桑尼亚北部不足6月婴儿，调研了其食物摄入量，并对其膳食暴露风险进行了评估。本研究共招募了143名婴儿作为调研对象，并且分别在1、3和5个月的时候进行调研，采用24小时膳食回顾法评估婴儿面粉摄入量，并用高效液相色谱技术对婴儿摄入的面粉进行分析研究发现，黄曲霉毒素和伏马菌素膳食暴露与婴儿发育迟缓或体重不足之间未发现显著得关联。
外文摘要：Infants less than 6 months of age receiving foods other than breast milk are at a high risk of exposure to . We surveyed food intake and estimated the risk of exposures to and for infants less than 6 months of age in Northern Tanzania. A total of 143 infants were progressively recruited and three follow-up visits were made at 1, 3 and 5 months of age. A 24-h dietary recall technique was used to estimate flour intake of infants who had been introduced to foods. and in the flours were analysed using high-performance liquid chromatography technique. Exposure to or was estimated using the deterministic approach. By the age of 3 months, 98 infants had started taking food; 67 of them, flours at levels ranging from 0.57 to 37.5065g per infant per day (average 865g per infant per day). Fifty-eight per65cent of 67 flour samples contained detectable (range 0.33-69.4765μg65kg(-1) ; median 665μg65kg(-1) ) and 31% contained detectable (range 48-122465μg65kg(-1) ; median 12465μg65kg(-1) ). For infants who consumed contaminated flours, exposure ranged from 0.14 to 12065ng65kg(-1) body weight (BW) per day (all above the health concern level of 0.01765ng65kg(-1) BW per day as recommended by the European Food Safety Agency) and exposure ranged from 0.005 to 0.8865μg65kg(-1) BW per day. Insignificant association was observed between exposure to or and stunting or underweight. Reducing and contamination of and dietary diversification can prevent infants and the public, in general, from exposure to the toxins.
