    It seems that you are very aware of the sources of aluminium are but it may be useful to know the PTWI (provisional tolerable weekly intake) has been set by the WHO at 2/mg/kg an example of which is shown as



    I hope that would be of some help.

    That WHO source is much appreciated and one I'd overlooked. The wheat example is a good one about plant uptake from the soil and I'm glad we've been gluten-free (and actually cut out almost ALL grains) for a few years now. One thing that bothers me is the verbiage where some of these sources say we "believe". That's why I've decided to take matters into my own hands by starting a solid record for at least my immediate environment, and then observe how levels might vary and if anything changes.

    Going off-site also, but to the CDC who I believe are fairly legitimate, I've read the long and boring AL study https://www.atsdr.cdc.gov/toxprofiles/tp22-c2.pdf

    I have an active interest in aluminium. I used to be a psychiatric nurse and trained in the '80's while there where still big institutions in the UK. Purely anecdotal but it was seen back then a concentration of aluminium in the plaque of alzheimer's patient. However the current research can go one way or the other in so far that the aluminium causes the plaques or the plaques cause the aluminium. That is a different issue.

    I have no idea of the country you are posting from but you may find a couple of links from the UK. The UK has a network that measures Al in rainwater, an example shown in the link below. I apologise for no direct link but it is page 18 of 105

    The sites and data for the UK can be followed through the Heavy Metals map via this link:
