Abstract: Aluminium (Al) is well known to be a toxic metal, particularly in patients with chronic renal dysfunctions. It is therefore, crucial to determine the levels of the element in dietary matrices with a view to estimating the daily dietary intake. In the present research, the total content of Al from different sources is present. Analytical technique employed is Graphite Furnace Atomic Absorption Spectrometry (GFAAS). Samples analyzed were beef baked in Aluminium foil, drugs (tablets) and beverages. Results indicate Al in the range 59.83-220.20 mg kg-1 baking duration 60-180 min beef, 1.05-1.42 mg g-1 drugs and 0.171-0.481 mg g-1 for both bottled and Al canned beverages. The standard deviation of the means is from ±1.31 -±69.54, ±0.055 -±0.187 and ±0.105 -±0.117; baked beef, drugs and beverages, respectively. Al content is lower than the daily dietary intake of 60 mg for an average body weight of 60 kg as set by WHO/FAO as tolerable based on product packaging/serving or doses normally prescribed. However, a pool of the metal from all the sources investigated and other sources may significantly increase the daily dietary intake above the WHO/FAO specification, which may become deleterious to health.
