摘要
目的:研究人体铝摄入的主要来源。方法:采用铬天青S分光光度法,采取生活饮用水、市售多种食品进行铝含量测定,对铝制炊具的铝溶出量进行测定。结果:生活饮用水铝含量为0.0147±0.0022 mg/L;食品中油条、粉条铝含量较高,特别是油条中铝含量平均为860.7 mg/kg,最高达1012.1 mg/kg,粉条中铝含量高达395.3 mg/kg;铝制炊具铝溶出量测定结果显示,符合卫生标准的饮用水在铝制炊具中存放24 h后,水中铝含量即会超标。在酸性及盐性介质中,铝溶出量远远大于自来水中,而且铝溶出量随使用温度的升高和存放时间的延长而增加。结论:食物性铝和铝制炊具的溶出铝是人体摄入铝的主要来源。
Objective：To study the main source of aluminum that people take in. Methods.The quantity of Al in drinking water, various kinds of food and that dissolved from cooking utensils made of aluminum was determined by chrome azurol S spectrophotometry. Results：The content of Al was 0, 0147 ± 0. 0022 mg/L in drinking water, 395.3 mg/kg in sweet potato noodle, 860. 7 - 1012. 1 mg/kg in fried bread stick, and that dissolved from cooking utensils made of aluminum is becoming great after being stored for 24 hours. The amount of Al was much more great in acid or salt solution than in water and increased with the cooking temperature and storage time. Conclusion：The main source of Al that people take in is the food and that dissolved from utensils made of aluminum.
