I must admit that I was a bit surprised by the lead ... but then until relatively recently most folks thought that cyanide was regarded as (a) toxic and (b) not necessary for survival ... but now my understanding is that it's widely accepted that trace amount so cyanide are absolutely essential to maintain a variety of our biological processes.
The source i used was quoted in th earticle (Source: H. A. Harper, V. W. Rodwell, P. A. Mayes, Review of Physiological Chemistry, 16th ed., Lange Medical Publications, Los Altos, California 1977.)
Hope this helps
I don't think that there's evidence to show that lead is required by the human body for survival as stated in the article. It's usually regarded as toxic in any quantity.
Is there a reliable source for this assertion?
Thank you Max for all your nice work and your info. I was told that the human body is made up of 41 chemical elements that are found in "dust". Can you please tell me exactly what 41 chemical elements the human body is made up of that are present in "dust"...what are they please?
Speaking of bonding -- do you know how to find out who loves you more -- your wife or your dog?
All you have to do is to lock them both in the trunk (boot) of your car for 1 hour -- then when you let them out see who is the most pleased to see you (grin)
