食源性铝污染及其暴露评估

Foodborne Aluminum Contamination and Exposure Assessment

了解德州市市售食品的铝污染现状,并评估德州市人民的铝暴露情况。本研究以调查问卷的形式获取了德州市居民对常见市售食品平均日摄入量,并对15种常见的市售食品试样采用微波辅助消解,以铬天青S为显色剂,在乙酸–乙酸钠缓冲体系进行显色反应,结合紫外分光光度准确检测铝的含量。结果显示,其中12种食品铝残留量低于铝含量国家标准100 mg/Kg的上限,3种食品铝含量超标,整体合格率为80%。德州市部分食品的铝残留量存在安全隐患,相关部门应该加强监管力度。

Understand the status of aluminum pollution of food sold and evaluate the aluminum exposure of people in Dezhou. In this study, the average daily intake of common market food was obtained by questionnaire, and the color response of 15 common market food samples was taken by microwave assisted digestion, chrome azurol S was used as chromogenic agent, and the chromogenic reaction was carried out in acetic acid-sodium acetate buffer system, and the content of aluminum was accurately detected by ultraviolet spectrophotometry. The results showed that the residue of 12 kinds of food was lower than the upper limit of 100 mg/kg of the national standard of aluminum content, and the content of three kinds of food was excessive, and the overall qualified rate was 80%. There are safety risks in the residual aluminum of some food in Dezhou, and relevant departments should strengthen supervision.
