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.
