SO2 causes a wide variety of health and environmental impacts because of the way it reacts
with other substances in the air. Particularly sensitive groups include people with asthma who
are active outdoors and children, the elderly, and people with heart or lung disease.
Respiratory
Effects from Gaseous SO2 - Peak levels of SO2 in the air can cause temporary breathing
difficulty for people with asthma who are active outdoors. Longer-term exposures to high levels
of SO2
Respiratory Effects from Sulfate Particles - SO2 reacts with other chemicals in the air to form
tiny sulfate particles. When these are breathed, they gather in the lungs and are associated
with increased respiratory symptoms and disease, difficulty in breathing, and premature death.
gas and particles cause respiratory illness and aggravate existing heart disease.
Visibility Impairment - Haze occurs when light is scattered or absorbed by particles and gases
in the air. Sulfate particles are the major cause of reduced visibility in many parts of the U.S.,
including our national parks.

Acid Rain - SO2 and nitrogen oxides react with other substances in the air to form acids, which
fall to earth as rain, fog, snow, or dry particles. Some may be carried by the wind for hundreds
of miles. Plant and Water Damage - Acid rain damages forests and crops, changes the
makeup of soil, and makes lakes and streams acidic and unsuitable for fish. Continued
exposure over a long time changes the natural variety of plants and animals in an ecosystem.
Aesthetic Damage - SO2 accelerates the decay of building materials and paints, including
irreplaceable monuments, statues, and sculptures that are part of our nation's cultural heritage.

Health risks (short and long-term) may remain an open question, but homeowners
exposed to Chinese drywall have been reporting similar physical ailments and
symptoms including acne, asthma attacks, bloody noses, congestion, coughing,
dizziness, ear infections, eye irritation, fatigue, fertility problems, gastrointestinal
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 are symptoms which can be caused by a number of
factors and to date, 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 - unfortunately, the symptoms reoccur when they return 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
(even if your physician is not familiar with Chinese drywall) 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.
Recent reports (unverified) also include an increase in cavities (possibly caused
by the strontium) and fertility issues. Please let us know if you are
experiencing these symptoms.
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.

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. CLICK HERE FOR CDC GUIDE FOR

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. Click here for Dr. Manis'
Presentation.

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, HeraldTribune.com,
