“…Recent studies indicated that A1 in tea leaves and tea infusions could be a possible source of dietary A1 [3 -61. A1 is reported to have a suspect role in ALZHEIMER'S disease [7] and a definite role in osteodystrophy [8]. FAOjWHO expert committee [9] hiis set the Provisional Tolerable Weekly Intake (PTWI) of A1 as 7 mgjkg body wt.…”

SummaryAluminium content of tea leaves has been engaging the attention during recent years because of its uptake in the form of beverages such as tea. Hence, data were generated on the Al content in tea and its infusions, using an inductively coupled plasma spectrometer. The average values of Al in fresh tea leaves and commercial tea powders were 250 and 325 pg/g dry wt., respectively. Tea infusions contained 20-80 pg/l of Al. Al complexes with tea components like tannic acid and theoflavins were studied and stability characteristics as well as the nature of the complexes were computed. Zusarnrnenfassung

Aluminum ions (Al) and chromium (III) ions (Cr), as they exist in aqueous solution at neutral pH, adsorb onto calcium hydroxyapatite crystals (HAP) and severely inhibit their dissolution process, when present in concentrations less than 1 microM. Iron (III) ions (Fe), at concentrations up to 10 microM, have no effect on the dissolution process of HAP. The Fe-chelating agent desferrioxamine also forms strong complexes with Al but not with Cr. Desferrioxamine prevents the adsorption of Al to HAP and removes pre-adsorbed Al from the HAP surface, although not instantaneously, but has no significant effect on the adsorption of Cr to HAP. Desferrioxamine is also found to be capable of removing Al preadsorbed to bone powder.
