Health risks may remain an open question, but homeowners exposed to Chinese
drywall often report similar physical ailments and symptoms including acne, asthma
attacks, bloody noses, congestion, coughing, problems, hair loss, headaches, hives,
irritated eyes, joint and muscle pain, miscarriages, nausea, nosebleeds, phlegm,
rashes, runny nose, shortness of breath, sneezing, sinus problems, sore throat,
tightness of the chest, trouble breathing and urinary tract infections after being
exposed to Chinese drywall.    

Unfortunately, many of these symptoms can be caused by a number of factors and to
there is no scientific proof that Chinese drywall is the culprit.  The key is
homeowners who did not have these symptoms or did not have the
same severity prior to moving into contaminated home.   Many see vast
improvement after leaving their home.   

Certain people appear to be more prone to symptoms, including children, the
elderly and those with compromised immune systems.   Many feel the effects at
their weak spot.  For example, those who had asthma as children, often experience
similar symptoms as adults when exposed to Chinese drywall.   
Please seek
medical attention  and contact your local health department to report any health
effects you believe may be caused by Chinese drywall
.  Reporting is essential to
developing valuable scientific data.

According to the Centers for Disease Control and Prevention, an extended study of the
long-term effects of exposure to defective Chinese drywall is not necessary.

HEALTH SYMPTOMS
WELCOME TO CHINESEDRYWALL.COM
The first website dedicated to educating the public about Chinese drywall

GUIDE FOR DOCTORS   

On June 3, the federal Agency for Toxic Substances & Disease Registry, an arm
of the Centers for Disease Control and Prevention, released a
guide for doctors
and others dealing with questions about the tainted drywall.   Few studies exist of
people exposed to low levels of sulfur gases for long periods of time, however,
the ATSDR said that short-term exposure to sulfur gases such as carbonyl
sulfide and carbon disulfide, both of which have been found in Chinese drywall,
can cause eye irritation, sore throat, stuffy nose, cough, shortness of breath,
chest pain, nausea and headaches – symptoms that can be caused by multiple
other factors, but which resemble the complaints voiced by residents.  Longer
exposures can result in fatigue, loss of appetite, irritability, poor memory,
insomnia and dizziness, according to the agency. Older people, children and
those with asthma or chronic obstructive pulmonary disease are more likely to
feel the effects of sulfur gases, the ATSDR said.

Chinese Drywall - A Health-based Perspective

Barbara Manis, MD, Chief Medical Officer, Building Health Sciences, attended the HB
Chinese Drywall Litigation Conference on June 18, 2009, in New Orleans, LA.  Her
discussion addressed the reported and potential health effects associated with the
emissions thus far identified from imported drywall.  

Concern over the potential health effects which may be associated with Chinese
Drywall is further tempered by the possibility that there may be other, as yet
unidentified, substances in the drywall or other building materials in these homes which
are acting as potentiators making the low levels of sulfur more reactive with copper in
the air conditioner coils.  Science and research are in their early stages and,
therefore, it is impossible to determine if health effects.

Trigeminal nerve may explain the health problems homeowners
have been experiencing

The issue of the potential health effects of Chinese drywall was at the center of many
discussions, with government and most private consultants saying that more studies
were needed -- though so far testing has not found levels of individual chemicals
considered "toxic."

Lynn Wilder, a scientist with the Centers for Disease Control and Prevention's Agency
for Toxic Substances and Disease Registry, said she believed it would be fruitful for
studies to examine what are known as "additive" effects of the sulfur compounds
coming from the drywall.         In other words, Wilder said, there could be low levels of
each individual chemical, but "all of them combined might pose a problem." . . .
Robert DeMott, a toxicologist with Environ, a consulting firm working for builders
including Lennar Corp. and Taylor Morrison, also said the mixtures of gases may
lead to higher overall concentrations, as "multiple sulfur gases stimulate the same
nerves."  

Much of the health discussion centered on whether symptoms homeowners have
been experiencing could be the result of "neurogenic inflammation" brought on by the
trigeminal nerve, also known as the fifth cranial nerve, which branches out behind the
face and throat, with exposed endings in the nose.

Sulfur gases present in lower levels than are formally considered "toxic" can cause the
nerve to trigger the inflammation, resulting in health effects that include sinus and
nasal congestion, headaches, eye irritations, and throat and upper respiratory
problems.   Those effects generally subside once exposure to the offending chemicals
ends, as opposed to toxic effects, which can linger for longer periods of time and
require healing of damaged cells.  Excerpts from Article written by Aaron Kessler,

DISCUSSES HEALTH EFFECTS ON
THE DR. NANCY SHOW ON MSNBC
Many homeowners living
with Chinese drywall
report a wide range of
adverse health effects but
one which tends to be
glossed over is fatigue, so
severe at times that some
homeowners are falling
asleep on the job.  Most
do not realize that it could
be attributed to the
Chinese drywall in their
home.   Sulfur gases can
cause inflammation,
resulting in sinus and
nasal congestion, which
impedes quality sleep.   
This in turn can cause
malaise, which is
sometimes described as
feeling “blah” or “out of
sorts."   Fatigue and
malaise often feed off
each other making it hard
to determine where one
begins and the other
ends.   Most believes
these symptoms are short
term and will disappear
once no longer exposed
to the drywall.
WHAT IS CHINESE
DRYWALL
FATIGUE ("CDF")?  
DOES CHINESE DRYWALL PRESENT A FIRE RISK?

Yes, according to a report on the CPSC's website.  The report cites several concerns,
including deterioration of electrical connections that could develop "hot spots resulting
in overheating and possibly fire;” damage to circuit tracers causing failure of
protective devices such as GFCIs, arc-fault circuit interrupters and smoke alarms,
which can present shock and fire hazards from the loss of protection; and potential
gas leakage due to corrosive pitting of piping, which could present a fire or explosion
hazard.

PETS ARE AT RISK TOO

Please see your vet if your dog or cat has a cough (wet or dry), sneezing,
difficulty breathing or wheezing.  Ask your vet to check WBC, plateletes,
monocytes, lymphs, eosinphils and neutrophils.
