Aluminum Unibody MacBook Pro - Possible Aluminum Toxicity Source?

Aluminum is the third most common element on Earth. We are exposed to it constantly. The amount of extra Aluminum you would absorb from your laptop is too small to measure.

On exposure to oxygen Aluminum forms an oxide that seals the surface. This is form we are exposed to.

The amount you would possibly absorb is very small if any. There are likley more sources that you encounter every day.

Last I read, the link between Alzheimer's and Aluminium was unproven and there were more likely triggers.

I am sure there is a fair bit of info from your local Alzheimer's society.

Aluminum quickly forms a thin layer of oxidation when exposed to air. Most harmful exposure to aluminum is in the form of water-soluble aluminum ions, or very fine particles such as in manufacturing. I would be more afraid of that aluminum Pepsi can or the pan I prepare my dinner in. (hint) I don't spend much time worrying about that either.
