Thanks for all this info.  I really appreciate it.  at this point a lot of it 
is over my head but I will read it some more later.  In regard to copper (CU 
I believe) a man e-mailed me colloidal copper turned his wife's gray hair 
back to 80% natural color and I think he said she is around 60.  But, I have 
heard that supposedly Copper can cause health problems and there is some book 
about this saying many with CFS have copper toxicity.  But, I have never 
researched that or read up on it myself.

 What is a heavy metal?
 
 "Turning to regular dictionaries (as opposed to chemical dictionaries):
 Webster (3) gives "A metal of high specific gravity; esp: a metal having
 a specific gravity of 5.0 or over."
 
 All the metals that I think of as heavy metals have densities above 5
 g/cm3, while no metals with densities below 5 have heavy metal
 chemistry. This supports Webster's definition, but it is deceptive.
 Being a heavy metal has little to do with density, but rather concerns
 chemical properties.
 
 The metals that I have seen referred to as heavy metals comprise a block
 of all the metals in Groups 3 to 16 that are in periods 4 and greater.
 This seems to be a definition that should be generally useful. It may
 also be stated as the transition and post-transition metals."

 "heavy metal
 
 In the human health context, heavy metals are transition metal elements
 in the sixth and heavier periods, which should be present only in small
 quantities. Like lead Pb) and mercury (Hg), for instance.
 In microelectronics, heavy metals are period four and six transition
 metals that are troublesome contaminants because of their electrical
 properties. Au (see Gold) and Pt are lifetime killers in Si. Fe, Cu, Ni,
 and Cr, in period IV, have atomic weights in the range 51 to 63, or
 about twice that of Si. They're at the top of the famous curve of
 (nuclear) binding energy, so they're rather common.
 
 Because the conventional definitions include only transition metals,
 they exclude, amusingly, barium (Ba), whose name means heavy."

 "The term heavy metal has apparently arisen as a convenience among
 policy makers for referring to metals with potential toxicity. Cadmium,
 mercury, lead and bismuth are often mentioned, partly because human
 activities have increased their concentration in the environment. Other
 metals are also associated with health problems. On the other hand, all
 are not, gold being an example because it cannot be easily absorbed by
 the body. Moreover, even light metals may cause health problems.
 
 A scientific definition of heavy metal might be based on whether a metal
 has a lower or higher density than its oxide. The dividing line in the
 periodic table will then go through titanium, which has several oxides,
 some of which are heavier and some lighter than pure titanium. Another
 approach defines heavy metal as one that has a density greater that 6.0
 grams per cubic centimetre. Thereby, metals heavier than vanadium would
 be heavy metals, thus including most of the commercial metals."
