深圳市福田区日常食物的铝含量及居民暴露量评估

Evaluation of aluminium level and exposure in daily food in Futian district of Shenzhen

目的:了解深圳市福田区食品中各类食物中铝含量,并评估居民铝的暴露量情况,为今后开展监管工作提供依据。方法:2010年-2011年从辖区采集市售粮食、蔬菜等13类食品共311份,按照国家标准方法检测食品中铝的含量。根据2002年居民膳食营养调查中食物的摄入量,结合食物中铝含量的结果,进行食品中铝的暴露量评估。结果:部分面制食品中的铝含量超标较严重,居民每日通过日常食物摄入的铝量为13.4mg,比WHO/FAO的ADI值(60mg/d)低。结论:目前居民食品中铝的摄入量是安全的,但需要加强面制食品的监督管理,以保护消费者身体健康。
