Sorry, but it is common sense that Aluminum is poisonous already, from the way it is harvested from earth and further refined in jaw dropping filthy industrial processes. It is assumed to cater Alzheimer. The net is full of videos on Aluminium. A fraction is still only recycled ! It is used in all sort or medicine coats / pills and in all sort of sprays (almost all deodorants have Aluminium inside). All Apple products, most audio product are questionable with Aluminium. I find by comparison the point of toxicity of the little bits of Beryllium rather of minor impact and well a bit shallow ignoring most other stuff around us.

EDIT: message was typed on Macboor Air made of Aluminum !

Cheers, Andreas
