PGA Action at WTO Seattle - http://members.aol.com/pgacaravan

   Here finally seems to be some solid information on the toxic elements
of
the tear gas used in Seattle.  It is OUTRAGEOUS, but not surprising,
given
the early symptoms that were coming in from the medical staff at the
time.
While the police had admitted to OC and CS gas before, this was not the
case with the CN gas, containing methylene chloride.

    Appended is the technical information on methylene chloride.  Note
under the last point in the second message, under point #5: "PERMISSIBLE
EXPOSURE LIMIT (PEL):     MG/M3 (500 PPM)" means that the permissible
limit
is 0.  

    This should keep a bunch of them doing a whole mess of damage control
for a while.  

    But it also means a whole whack of us got hit with massive amounts of
deadly toxins in the chemical warfare that the state unleashed on us in
Seattle.  And we will have to live with that posioning for the rest of
our
lives.  It was chemical warfare against internal dissent using chemicals
of
mass destruction.  Is this not a crime against humanity?  Was that not
why
the governments said they bombed (and continue to silently bomb) Iraq? 
Cuz
Iraq allegedly had weapons of mass destruction (ie nerve gas).  Well, not
only does the USA government have such weapons but it uses them AGAINST
THEIR PEOPLE.  And it does so when its people are engaged in non-violent
civil disobedience.

    Any lawyers out there who want to take this one as far as it'll go?
It'll go quite a ways!
    How about human rights organizations?  Surely we get to at least
complain about them killing us!  Never mind dreaming about making them
actually ACCOUNTABLE for these crimes.

>>>The Washington Toxics Coalition recently requested and received
Material
>>>Safety Data Sheets from the Seattle Police Department for all
chemicals
>>>used in crowd control during WTO protests the week of November 29. 
The
>>>Department reported the use of an OC gas (active ingredient is
oleoresin of
>>>capsicum), Pyrotechnic CS agent (o-chlorobenzalmalononitrile) and
Liquid
>>>Agent CN (chlorolactetophenone).
>>>
>>>One disturbing find was the solvent used in the CN agent.  The MSDS
>>>indicated that the agent is 50% active ingredient and 50% methylene
>>>chloride as a solvent.  Methylene chloride is a possible/anticipated
>>>carcinogen as reported by the National Toxicology Program and the
>>>International Agency for Research on Cancer.  The National Library of
>>>Medicine's Toxnet website reports it to be an experimental carcinogen,
>>>tumorigen, teratogen (causes birth defects when it reaches egg or
sperm
>>>cells of the parents, or the developing fetus) with experimental
>>>reproductive effects.  The site also indicates that human mutagen
(causes
>>>mutations in cells) data exists.
>>>
>>>In addition to these serious effects, central nervous system
depression is
>>>reported.  Many of the nervous system effects given on the Toxnet site
are
>>>similar to those experienced by protesters.  Some of the symptoms
listed by
>>>Toxnet are lethargy, mental confusion, headache, tingling of the
limbs,
>>>acoustical and optical delusions, liver and kidney damage, increased
risk
>>>of spontaneous abortion, coma, and death.
>>>
>>>Another dangerous effect of methylene chloride is described in
Gosselin's
>>>Clinical Toxicology of Commercial Products.  The compound is
metabolized to
>>>carbon monoxide in humans, which could be dangerous to persons with
asthma
>>>or cardiovascular problems.
>>>
>>>In short, methylene chloride is a dangerous solvent suspected of
causing
>>>cancer, tumor growth, birth defects, reproductive system effects, cell
>>>mutations and central nervous system depression.
