上海市居民面制品中铝暴露的概率评估

目的 了解上海市居民面制品中铝的暴露水平,评估上海市面制品铝污染的健康风险.方法 对上海市面制品铝含量进行监测,结合上海市居民面制品摄入量调查,采用世界卫生组织( WHO)/联合国粮食与农业组织(FAO)的《食品中化学物风险评估的原则和方法》推荐的概率评估法,进行上海市居民面制品中铝的暴露评估.结果 上海市居民平均每周从面制品中摄入铝3.51 mg/kg BW,为暂定的每周可耐受摄入量(PTWI)的3.51倍；其中＜3岁的婴幼儿、3 ～17岁儿童青少年、≥18岁成人、孕妇平均每周从面制品中摄入铝分别为5.93、3.30、1.80、1.78 mg/kg BW,分别为PTWI的5.93、3.30、1.80、1.78倍.上海市居民每周从面制品中摄入铝P90为8.26 mg/kg BW,为PTWI的8.26倍；其中＜3岁的婴幼儿、3～17岁儿童青少年、≥18岁成人、孕妇每周从面制品中摄入铝P90分别为13.86、7.68、4.23、4.12 mg/kg BW,分别为PTWI的13.86、7.68、4.23、4.12倍.结论 上海市居民从面制品中摄入铝的量已大大超过PTWI,存在很大的风险,其中以婴幼儿风险最大、儿童青少年次之.

Assessment on the probability of aluminum exposure from flour products in Shanghai residents

Objective To obtain the basic data of aluminum exposure from flour products in Shanghai residents,and to estimate its health risks.Methods For the assessment of aluminum exposure from flour products in Shanghai residents,the probabilistic estimate method recommended by WHO/FAO on Principles and methods for the risk assessment of chemicals in food was applied.Monitoring the concentration of aluminum in flour products combined with a survey on flour products intake of Shanghai residents was conducted.Results ...
