This was a good post. I only have the following comments:

Zenz p. 584 (Mn section written by Shiro Tanaka) doesn't say anything about
skin absorption of inorganic Mn compounds:
"Inhalation is the major route of entry in occupational manganese poisoning,
although excessive gastrointestinal absorption may also occur in setting of
poor industrial or personal hygiene. (17) Tricarbonyls of manganese can be
absorbed through the skin. (4) Intoxication from contaminated drinking water
has also been documented. (32)"
My guess is that, like lead and many other metals, skin absorption was just
assumed not to be significant. That's why the study of radio tagged lead on
the skin a few years ago was such a surprise to many. Until similar studies
are done on Mn, I think we should not presume.
I didn't see anything on skin absorption of Mn in Patty's either.

Have you published anything on this? The Harvard School of Public Health is
looking for anything on MN and artists/craftspeople. I'd also like to know
more about these cases.

And other activities. For example, some potters are cutting apart old
batteries and salvaging the Mn.

Monona,
With reference to your post about Manganese and health dangers, I
believe there was a long letter in Ceramic Review a few years ago by
someone who was warning about the dangers as she had developed Parkinson's,
as I remember, and attributed it to manganese fumes. I am sure that the
publication would be able to give you the information.

I think this is Jane Watkins, but I will forward your post to my contact at
the Harvard School of Public Health and suggest they look through the
archives of the Ceramic Review.
Thanks for the Lead. We need to help those few researchers who are working
on problems like these.

I'm an old person as well, and if you have had ALL of these symptoms since
you were age 60, you really need a doctor to figure out what's wrong. My
memory is better now than it ever was. I'm never nervous--even when I
should be. My voice is not hoarse. I still have excellent dexterity and
coordination. I sleep with no difficulty. And most of my geezer friends
and my husband are in similar condition.
As far as "irritability" is concerned, my friends think I'm a pussy cat, but
I probably wouldn't get a clean bill of health from Clayarters.

----------------------------------
Chelation takes toxic metals out of your bones and tissues and puts them back
into your blood stream where your liver and kidneys can have another crack at
eliminating them from your body. This, of course, stresses the liver and
kidneys and your health problems can go from being chronic to being acute.
Chelation usually should be done in a hospital, by IV, so that your blood and
urine can be monitored for levels over which the damage being caused is not
balanced out by the benefits of removal. Natural chelating agents have
varying efficacy, so it is difficult to know if you are getting too much or
too little.
The only exception, is the new chelating agent for lead. The old agent was
ethylenediaminetetraacetic acid (EDTA). Unlike EDTA, the new one,
2,3-dimercaptosuccinic acid (DMSA), is specific for lead, has only minor side
effects, and can be used on an outpatient basis.
And this brings up other points: all chelating agents have side effects and
no one chelating agent is good for all metals.
If you get your chelating agent from some health food store, you better hope
that one of two things are true: either you don't really need it, or it
doesn't work. Because if you need it and it works, you may really harm
yourself.
Instead, get sound medical advice from a real doctor.
