摘　　要：目的了解湖北省植物性食品中铝本底含量情况,并对居民来源于植物性食品的铝摄入状况进行暴露评估。方法2013年从湖北省3个市、县,10个镇的集贸市场、临时摊点、农家村户、小商店等随机采集粮谷类、叶菜类、甘蓝类、水果类等11类共393份样品,按照国家标准GB/T23374-2009《食品中铝的测定电感耦合等离子体质谱法》测定其中的铝含量。将第五次中国总膳食研究(CTDS)中湖北省居民食物消费量数据引入,分别计算植物性食品铝平均暴露量和P97.5水平铝的高端暴露量。结果植物性食品中铝平均含量为(3.07±5.80)mg/kg,调查人群来自植物性食品的平均铝暴露量0.16mg/(d·bw),为每日可耐受暴露量(Acceptable Daily Intake,ADI)的0.57倍,植物性食品铝本底含量在第97.5百分位数的情况下,调查人群总的铝暴露量为0.80mg/(d·bw),为ADI的2.86倍。结论需要关注湖北居民植物性食品中铝食用安全情况,尤其是粮谷中的铝。在此基础上,应纳入其它含铝添加剂食物如油条、包子等调研,进行更加精细和全面的膳食铝健康危害风险评估。Objective To understand the aluminum background content of plant foods in Hubei Province,and to evaluate the exposure of residents to the aluminum intake of plant foods. To investigate the aluminum background content of phytogenic foods in Hubei Province,and to make exposure assessment of aluminum intake. Methods In 2013,a total of 393 samples of cereal grain,leaf vegetables,cabbages and fruits were randomly collected in bazaars,temporary stalls,farmhouses and small shops in 3 cities and counties,and 10 towns of Hubei Province. Aluminum content in the samples was determined according to the national standard GB/T 23374-2009 "Inductively Coupled Plasma Mass Spectrometry for Determination of Aluminum in Food". The food consumption data of Hubei residents in the fifth China Total Diet Study (CTDS) was introduced to calculate the average exposure of plant food aluminum and the 97.5th percentile level of aluminum exposure of each group. Results The average content of aluminum in phytogenic food was 3.07±5.80 mg/kg. The average value of aluminum exposure from phytogenic food of the total survey population was 0.16 mg/(d·bw), 0.57 times of ADI (Acceptable Daily Intake). In the case of the 97.5th percentile level of aluminum content,the aluminum exposure was 0.80 mg/(d·bw),2.86 times of ADI. Conclusion It is necessary to pay attention to the safety of the dietary aluminum intake of residents in Hubei,especially aluminum in grain. On this basis,other aluminum-containing additive foods such as dough sticks and steamed buns should be included for more detailed and comprehensive dietary aluminum health hazard risk assessment.
