Subject: Cobalt Poisoning
----------------------------Original message----------------------------
We would like any information anyone has on cobalt poisoning, treatments,
prognosis, and experts on the subject. Thanks.
------------------------------------------------------------------------
Its an experimental carcinogen, but there isn't enough human data yet to say
for sure. It also causes birth defects in animals and may in humans as
well. Like many toxic substances, it is needed in trace amounts in the diet
and is an important constituent of vitamin B12.
In toxic doses it damages the heart muscle. This was seen first in animals
and later was clearly demonstrated in humans when cobalt was added to beer as
a foaming agent. Some of these beer drinkers died from the heart damage.
Cobalt upsets the metabolism even to the point of causing goiter.
Interestingly, one of the studies that established the metabolic effects
determined by changes in thyroid hormone (thyroxin) were done on 61 Danish
female porcelain (cobalt blue) painters.
Cobalt can cause sensitivities and allergies including allergic dermatitis,
eczema, respiratory wheezing (like asthma), and alveolitis. The alveolitis
can progress to lung fibrosis.
There are also memory deficits seen in workers exposed to cobalt.
At present, there is no treatment for cobalt poisoning. If you are going
to go to a doctor about cobalt exposure, choose one with experience in
occupational medicine. Regular docs wont have a clue.
If you need an "expert," contact me in private with you home address and I'll
look through my lists.
Hope this helps.

I'm curious about this. What amount is a trace or is that too small to even
measure? How much would be considered dangerous?

Hi all,
dont forget there is cross allergy
between cobalt,chromium and nickel.
By the way, a good knowlwedge of your exposure to cobalt
is essential to determine the possibility to suffer from a cobalt
related disease.

Hi Sue,
In an analysis, trace simply means that the analyst got an indication that
the substance was present, but could not determine the amount, because it
was less than the sensitivity limit of his apparatus. So, that means that
"trace" has no definite quantitative meaning. It could be 1% or it could
be a part per billion or less. If you are reading "trace" off a list of
other analyses, you can sometimes get an indication of what the limit is by
looking at the other small amounts, but this is not always as good as you
may think, since sensitivities vary according to species. Best is if the
analyst records the amount as <1ppm, or something like that. Sometimes the
sensitivity may be stated elsewhere.

Hi Edouard,
What is a cross allergy between cobalt, chromium and nickel?

Hello Darrol,
it means if you are allergic to one of them,
you may be or become allergic to the other 2.
