EDTA- inorganic, organic and methyl mercury?

[Guest guest]

Hi all!

Does anyone know why EDTA is not a good chelator of mercury?

I spoke to a Chemist today and he said that is does chelate mercury!!

I am confused and this guy knows about mercury toxicity, so he says.

I also spoke to a Leon (He is with DAMS I thinks it stands for

Dentists Against Mercury Syndrome) He has new an new information

packet that he is going to send me and said there are some newer

things to chelate heavy metals. So I await the information that

he is going to send.

Also, does DMSA and ALA chelate all forms of mercury

inorganic, organic and methyl

Thanks again!

Because it is a tetracarboxylic acid, and carboxylates are " hard "

acids and thus do not bind strongly to a " soft " metal like mercury.

Sulfur is a " soft " ligand and binds well to soft metals. There are

other ways to describe it, but the " hard and soft acid and base "

theoretical discussion of inorganic chemistry is probably the one that

has the most hope of getting some glimmer of meaning through to

laymen.

Yes. And sodium. And aluminum. And every other metal in the

periodic table. The question isn't whether it binds, but whether it

binds to a clinically significant extent under physiologically

relevant conditions, and the answer is no.

Who is he?

Leo, at Dental Amalgam Mercury Syndrome. He is not a dentist or other

relevant professional. He is not knowledgeable about chelation. DAMS

basically promotes whatever view is currently trendy at IAOMT and

ACAM, which while professional organizations of dentists and doctors

don't really have a helpful or appropriate chelation protcol to offer.

They got sucked into the DMPS study disaster and haven't recovered

from it enough to figure out a new approach.

Yes. Methyl mercury IS organic mercury. And all forms of organic

mercury convert to inorganic mercury in humans in a few months, and do

not change back to organic form. Only fish change it back.
