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 10mg/kg. Aluminum contents were higher in foodstuffs of plant origin, especially dry beanscontaining large amounts of aluminum naturally. Lower concentration of aluminum seemedto 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 dailydiets of college students, which was 4.86±1.72mg. 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.

Aluminum, the third most abundant element in the earth’s crust, comprises about 8% of the total earth elements. It is not considered to be an essential trace metal for mammals, although it does occur in the body. As aluminum compounds are extensively used in foo (...)"
