[Objective] To determine the aluminum content in saled fried bread stick and residents' consumption to provide basis for the estimation of dietary aluminum exposure level.[Method] We selected 158 samples for supermarkets and fast food shops using random sampling method.Residents' aluminum intake was calculated by according to the national standard method.[Result] Among 158 samples,19samples was qualification.The rate of qualification was 12％ and aluminum mean content was 247.3mg/kg,the median value of 178.2 mg/ kg.There was no significant difference between sampling sites.There was no significant difference between different district.The mean intakes of aluminum in Xianyang city residents was 6.7 mg/d.There were no significant differences between regions,while there was a significant statistic difference between gender.[Conclusion] The aluminum content of saled fried bread stick in Xianyang exceeded the allowed limit.The results indicated the residents intaked aluminum through saled fried bread stick.Residents of long-term eating twisted cruller can cause aluminum toxicity.Measures should be taken to reduce the aluminum content,the supervision and management departments should be strengthened.%目的:检测咸阳市市售油条中铝的含量及人群的摄入量,为估计咸阳市居民铝的膳食暴露量提供部分依据.方法:2013年12月采用随机抽样方法,采集咸阳市早餐供应点、超市及快餐店的样品共计158份,按照国家标准方法检测油条中铝的含量,并根据检测结果计算居民铝的摄入量.结果:所检测的158份样品中只有19份合格,合格率为12％,铝含量的均值为247.3mg/kg,中位值178.2 mg/kg.不同采样地点样品中铝含量均值无显著性差异,不同区样品中铝含量均值无显著性差异.居民通过油条摄入铝的平均量为6.7 mg/d,被调查居民通过油条摄入铝的量,在地区上无显著性差异,在性别上差异有统计学意义.结论:咸阳市市售油条中铝含量超标,被调查居民每天通过油条摄入一定量的铝,长期食用会引起铝中毒,应采取方法降低油条中铝的含量,呼吁监督管理部门应加强监督.
