ABOUT CHINESE DRYWALL TESTING |
|

|

Chinese Drywall Poses Potential Risks to
American Homeowners and Apartment Dwellers
U.S. homes, condos, apartments, and offices
built or remodeled between 2001 & 2008 may have
been constructed with Chinese drywall. If your
office, home or condominium was built or
remodeled after 2001, and you have experienced
numerous air condition coil failures, your
copper electrical ground wire has turned black,
or you are suffering from unexplained upper
respiratory issues, nose bleeds, rashes, or
severe allergy type symptoms, it is possible
that you are living with toxic imported Chinese
Drywall. If this is the case, you should
consider having
your drywall tested.

At the height of the U.S. housing boom starting
in 2004, when building materials were in short
supply, American construction companies used
millions of pounds of Chinese-made drywall
because it was abundant and cheap.
Now that decision is haunting hundreds of
homeowners and apartment dwellers who are
concerned that the wallboard gives off fumes
that can corrode copper pipes, blacken jewelry
and silverware, and possibly sicken people.
Shipping records reviewed by The Associated
Press indicate that imports of potentially
tainted Chinese building materials exceeded 500
million pounds during a four-year period of
soaring home prices. The drywall may have been
used in more than 100,000 homes, according to
some estimates.
Laboratory tests of samples for volatile
chemicals have identified emissions of the
sulfurous gases carbon disulfide, carbonyl
sulfide, and hydrogen sulfide. These emissions,
which have the odor of rotten eggs, worsen as
temperature and humidity rise. Homeowners have
reported respiratory tract infections, sinus
problems and nosebleeds.

Symptoms and source identifiers |
|
| |
 In
homes with the defective drywall, copper
surfaces such as pipes, wiring, and air
conditioner coils corrode, turning black and
powdery, a chemical process indicative of
reaction with hydrogen sulfide.
A home may have been built with drywall from
several sources, American and imported. Drywall
usually has a source printed on the back.
Chinese drywall may be marked "Made in China",
"China", "Knauf Tianjin", or have no marking at
all.

Radioactivity concerns |
|
| |
Concerns were raised about the presence of
phosphogypsum, gypsum formed as a by-product of
processing phosphate ore into fertilizer with
sulfuric acid. Phosphogypsum is radioactive due
to the presence of naturally occurring uranium
and radium in the phosphate ore. The substance
has been banned for use in U.S. construction
since 1989. Tests of drywall samples by the EPA
and the Florida Department of Health showed some
radioactivity, but at levels no higher than
those ordinarily found in the natural
environment.

Scam warnings |
|
| |
The Florida Attorney General's office has warned
of several deceptive practices targeted at
homeowners, including bogus test kits, home
inspection offers, ozone generators and chemical
cleaners. The warnings point out that the
presence of defective drywall cannot be
determined by testing a home's air, or corrected
by chemical sprays or ozone generators.

Link found between
Chinese drywall, corrosion
The federal government said Monday that it has
found a "strong association" between problematic
imported Chinese drywall and corrosion of pipes
and wires. |
