- Toxicity
- An element that is
abundant (about 8%) in the crust of the earth. Aluminum
appears to have no biological function and, from the point of
view of acute toxicity, is essentially non-toxic. Because it is
primarily eliminated by excretion, people with compromised
kidney function may accumulate the metal. In kidney dialysis
patients, this is a particular problem because the dialyzing
solution may contain high concentrations of aluminum. This
condition (dialysis encephalopathy or dialysis dementia) has
symptoms that include impaired memory, EEG changes,
dementia, aphasia, ataxia, and convulsions.One possible
mechanism of toxicity may be inhibition of hexokinases in the
brain. The chelating agent deferoxamine has been used successfully
in treating this condition.Aluminum is one of the primary toxicants leached
into surface water (and, therefore, water supplies) by acid
deposition. The connection between aluminum and Alzheimers
disease is controversial and many investigators believe there is
no connection.
Use
Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts.
