MCS Research and
Definition
The medical community
has long questioned the etiology of Multiple Chemical Sensitivity
(MCS) or Environmental Illness (EI). According to Cynthia Wilson
of the Chemical Injury Information Network, as long ago as the
1950's physician's recognized that people were becoming sick due
to their environment (http://www.ciin.org).
There have been many theories regarding the cause of MCS but due
to the lack of reliable scientific research, the medical community
and the general public have failed to recognize the physiological
effects of chemicals on the body.
In an article providing
an overview of MCS, Cynthia Wilson states, "The latest research
strongly suggests that chemical sensitivity is most probably some
combination of central nervous system damage and enzyme deficiencies
that can also cause problems with the endocrine and immune systems.
Chemical sensitivity is more often than not characterized by real,
verifiable damage to the body, though the implications of these
anomalies are poorly understood and need additional research."
(http://www.ciin.org). A researcher
by the name of Dr. M.B. Lax of the Central New York Occupational
Health Clinic offered his assessment of the current struggle in
understanding MCS. In an article entitled, Multiple chemical sensitivities:
The social construction of an illness, he wrote, "Multiple
chemical sensitivities (MCS) has emerged as an important and highly
controversial issue in occupational health. Debate centers on
whether the illness is "physical" or "psychological."
A strong corporate-backed campaign has framed the debate and has
pushed MCS advocates into a strategy of "proving the physical"
nature of MCS." (http://www.fiscorp.net/iaq/iaqapps4.html).
An article published
in the Archives of Environmental Health (Multiple Chemical Sensitivity:
A 1999 Concensus. 1999. Vol. 54, 147-149) provides information
regarding a consensus reached by medical professionals who have
agreed upon specific criteria to be used in determining a diagnosis
of MCS based upon a study by Nethercott et al. published in the
Archives of Environmental Health (Multiple Chemical Sensitivities
Syndrome: Toward a working case definition. 1993. Vol. 48, 19-26).
The criteria, in brief, require that symptoms are reproducible
with repeated chemical exposure, the condition is chronic, symptoms
result from low level exposure, symptoms improve or resolve when
the irritant is removed, response occurs to multiple chemically
unrelated substances and symptoms involve multiple organ systems.
Symptoms and Limitations
MCS or EI may develop
from exposure to substances in the environment and may result
in intolerance to even very low level exposure to chemicals. Symptoms
can occur in more than one organ system in the body, such as the
nervous system, the lungs and the vascular system. An individual
may be exposed through contact with, ingestion of or inhalation
of a specific or multiple irritants.
Limitations experienced
due to MCS or EI are experienced by each person individually so
it is important to evaluate each situation independently. Some
of the more common symptoms that develop from exposure to problematic
environmental substances may include one or many of the following:
headache, nausea, respiratory difficulties, fatigue, dizziness,
tightening of the throat, chronic laryngitis, difficulty concentrating,
memory loss, rash or hives, arthritis-like sensations or muscle
pain. Problematic environmental substances may include: fragrance
chemicals used in perfumes, colognes, cleaning products and deodorizers;
pesticides; fumes from building products, new furniture and carpet;
and tobacco smoke among other irritants.
Accommodations for
someone with MCS, should be considered on a case-by-case basis.
The following pages provide accommodation ideas and product referrals
based upon a non-inclusive list of functional limitations. The
material is provided for informational purposes only and should
not be considered absolute solutions to all accommodation situations.
