Systemic and Co-existing Forms of Chemical Sensitivity, along with some of the chemicals which triggered them

Anaphylaxis:   It impairs multiple body systems in one systemic fashion,
and it has been triggered by a number of chemicals at ambient (nontoxic)
levels.   The chemicals which have thus far been documented as having
triggered anaphylaxis at nontoxic levels include:

[01] the hair bleaching agent, Ammonium Persulfate.
[02] the antimicrobial agent, Chlorhexidine (0.05%).
[03] the medical disinfectant, Ortho-phthalaldehyde.
[04] the fungicide, Chlorothalonil (0.01% aqueous).
[05] the analgesic ingredient, Polyvinylpyrrolidone.
[06] the diagnostic agent, Isosulphan Blue Dye.
[07] the dialysis ingredient, Ethylene Oxide.
[08] the additive, Sodium Benzoate.
[09] the analgesic, Acetaminophen.
[10] the xanthine dye, Flourescein.
[11] the food coloring, Tartrazine.
[12] common aspirin.
[13] formaldehyde.
[14] nitrites.
[15] sulfites ... etc.

The existence of Systemic Chemical Sensitivity has already been docu-
mented under the name, anaphylaxis and even urticaria.   It is not a pro-
posed hypothesis yet to be proven.

An Assertion Negated by Evidence Gathered
in the Field of Occupational Medicine

An objection to the recognition of Multiple Chemical Sensitivity exist-
ed in the assertion that a chemical, whenever encountered at a nontoxic
level, cannot impair more than one body system in the same one person.
However, chemicals have individually done this during anaphylaxis.

In the world of occupational medicine there have been DOCUMENTED
instances where the same one chemical, at an ambient level, has impaired
two body systems in the same one worker (or subset of workers.)   This
phenomenon can be regarded as dual chemical sensitivity.  It has thus far
involved the integumentary system (the skin) in combination with the re-
spiratory system in the following forms:

[1] airborne irritant urticaria (hives) accompanied by rhinitis.
[2] asthma and rhino-conjunctivitis accompanied by dermatitis.
[3] asthma accompanied by dermatitis.
[4] asthma accompanied by urticaria.

Dual Chemical Sensitivity has already been documented.  It appears
in documentation under the title "co-morbid conditions," as well as
"coexisting conditions."   It is a documented phenomenon and not a
hypothesis yet to be proven.  The chemicals which have thus far been
documented as having induced it, in the world of Occupational Medi-
cine, include:

[1] dental acrylates;
[2] dusts of persulfate salts;
[3] epoxy resin diglycidyl ether of bisphenol A;
[4] leather tanning ingredient potassium dichromate;
[5] spray paint additive, polyfunctional aziridine cross-
linker CX-100.

The coexistence of different forms of localized chemical sensitivity en-
tirely negates the assumption that a chemical sensitivity reaction can
impair no more than one body system in a person at a time.  Clicking

dence, concerning dual chemical sensitivity

Pronounced Short-term Chemical Exposure 
Causing Long-term Illness in Dual Body Systems

Then there are cases where pronounced chemical exposure (such as
in the case of chemical spills) has resulted in adverse affects to dual
body systems.   It has furthermore resulted in chronic hypersensitivity
to a number of chemicals other than that which was encountered dur-
ing the chemical overexposure.

One case study involves a tank truck hauler who developed symptoms
during and after an eight and a half hour stay around an alleged tank of
paraffin, due to the fact that he experienced a tire blowout while driving,
and had to wait for a road crew to get him back on the road.

Within one hour of the blowout, the driver underwent racking cough,
a severe headache, and an irritated throat.  Within forty hours, his feet,
hands, and abdomen started to swell.  The swelling continued to the
point triggering shortness of breath and chest pains.  The medical ex-
amination of the driver resulted in the following objective findings:

[1] an elevated CD 26 cell count;
[2] a protuberant/distended abdomen;
[3] a decreased T-suppressor cell count;
[4] the presence of the antinuclear antibody;
[5] and the presence of the anti-thyroid antibody.
[6] the presence of the anti-smooth-muscle anti-body;
[7] liver function test results consistent with hepatotoxic

When the driver was examined a year after the blowout, he stated that
exposure to chemical agents resulted in his suffering gastrointestinal dis-
tress, fatigue, weakness, neuralgia, and irritability.  This is a description
of Multiple Chemical Sensitivity, and this is pertinent to note in light of
the fact that the detractors of MCS have repeatedly claimed that persons
manifesting signs of MCS have no objective medical findings to support
their reported symptoms.  This driver had seven objective medical find-
ings at the outset of his illness.

In meeting rooms where position statements are drafted, the name
Multiple Chemical Sensitivity was changed to that of Idiopathic En-
vironmental Intolerance.   This substitute title is an entirely erroneous
title in the case of the tank truck hauler, being that "idiopathic" means
"of unknown origin," and the hauler's ills originated at a known time
and a known place.

That case study and seven other ones are described in medical article
titled,  Reactive Intestinal Dysfunction Syndrome Caused by 
Chemical Exposures - RIDS. 

An Assertion in anti-MCS Literature Negated by
Evidence Gathered in the Field of Occupational Medicine

Needless to say, anti-MCS literature asserts that persons suffering from
MCS are merely mentally ill, despite the fact that there is no consensus
as to what particular type of mental illness this might be.  Nonetheless,
a few propagandists assert that persons suffering from MCS are mere-
ly phobic of chemical exposure, and that the fear of chemicals causes
them to imagine illness.   However, a number of persons suffering from
Multiple Chemical Sensitivity are those  who worked in chemically lad-
en environments for extended periods of time.   If such persons were
phobic of chemical exposure, they would have never taken the chemi-
cally laden jobs they took.   They would have never even applied for
those jobs.  The propagandists' assertion completely falls apart.
