Until then, I am not going to waste my time responding to you or big vince
in this thread.


kicked your butt, as usual

snip john's reply which had nothing to do with the thread

Will you at least admit that mercury chloride and thimerosal are
chemically different molecules? Will you also admit that different
compounds have different toxicities?


Why sure. Mercury chloride From Wikipedia -'Mercury(I)
chloride is the chemical compound with the formula Hg2Cl2. Also known
as calomel or mercurous chloride' and ........." Due to its low
solubility, mercurous chloride is less dangerous than its mercuric
chloride counterpart. From the early 1830s through the 1860s, this
compound was used as a laxative in the U.S. This previous use in
medicine as a diuretic and purgative was discontinued because of its
toxicity." .http://en.wikipedia.org/wiki/Calomel
again from Wikipedia .... 'Thiomersal (INN) (C9H9HgNaO2S),
formerly and still commonly known in the United States as thimerosal,
is an organomercury compound (approximately 49% mercury by weight)
used as an antiseptic and antifungal agent." and " Thiomersal is
harmful by inhalation and ingestion, lethal between 50 and 1000
times[citation needed][1] the usual intake (hazard symbol T+).[2] It
is a neoplastigen and a teratogen. Thiomersal is also dangerous for
the environment (hazard symbol N).

For more safety information on how to handle thiomersal, consult its
MSDS (material safety data sheet).

Thiomersal causes susceptible bacteria to autolyze (break down their
own cells with self-produced enzymes) via an unknown mechanism.
[citation needed] In the body, it is metabolized to ethylmercury
(C2H5Hg+) and thiosalicylic acid.[3]"

Mercury cloride has been used as a laxative { did doctors really
understand the risk] Thimerosal is much more toxic. Of course any
substance with mercury is a potential toxin. As you know a great deal
about chemistry and biology why would you intimate otherwise. Thanks

Uh, dude, the LD50 of thimerosal (oral testing in rats) is 75 mg/kg.
Mercury chloride's LD50 is 1 mg/kg.

Of course any substance with mercury is a potential toxin.


Any compound has *potential* toxic effects, even dihydrogen oxide.

As you know a great deal about chemistry and biology why would
you intimate otherwise. Thanks

Oh, I don't know. Maybe because of all the evidence?
