title: Preliminary study on aluminum content of foods and aluminum intake of residents in Tianjin.
abstract: Aluminum contents of 64 kinds mof foods in Tianjin were determined. The results showed that the aluminum levels in different kinds of foods varied greatly, and most foodstuffs from natural sources (including contamination from food processing) contained less than 10 mg/kg. Aluminum contents were higher in foodstuffs of plant origin, especially dry beans containing large amounts of aluminum naturally. Lower concentration of aluminum seemed to be present in foodstuffs of animal origin. It was estimated that the potential daily intake of aluminum per person from natural dietary sources in Tianjin was about 3.79 mg. This estimated figure of dietary aluminum intake was very close to the measured data from 24 daily diets of college students, which was 4.86 +/- 1.72 mg. Considering all the potential sources of natural aluminum in foods, water and the individual habitual food, it would appear that most residents in Tianjin would consume 3-10 mg aluminum daily from natural dietary sources.
