食品添加剂和污染物中铝的风险评估

以联合国粮农组织和世界卫生组织食品添加剂联合专家委员会（JECFA）第67 次和第74 次会议对食品添加剂和污染物中铝的风险评估报告为主要依据，分析了铝的毒性、来源和暴露情况。指出JECFA推荐铝的健康指导值是暂定每周耐受摄入量（PTWI）为2.0 mg/kg（按体质量计）。详细介绍了JECFA对食品添加剂和污染物中铝的危害识别、危害特征描述、暴露评估和风险特征描述，旨在方便快捷地了解国际组织对铝的风险评估情况，为开展食品中铝的安全性评价研究及相关工作提供参考。

Risk Assessment of Aluminum from Food Additives and Contaminants

This paper was to evaluate the health risk of aluminum from food additives and contaminants based on the evaluation reports at the sixty-seventh and seventy-fourth JECFA meeting. The toxicity, source and exposure of aluminum were analyzed. In addition, the committee set a provisional tolerable weekly intake (PTWI) of 2.0 mg/kg body weight for aluminum, including food additive usage. Hazard identification, hazard characterization, exposure assessment and risk characterization of aluminum from food additives and contaminants from the meetings of JECFA were introduced in detail, which could contribute to a convenient and quick understanding of risk assessment of aluminum in the international organization, and provide a reference for the research on safety evaluation of aluminum in food and the relevant work.
