I'm chemically sensitive, and belong to MCS fora. This, with permission to forward, was posted in one of them on Sunday.
If it doesn't belong here, please put it in the proper place.

"Another downside of that housing bubble that so many hailed to be good for this country, while some of us waited for the other shoe to drop! Well, that shoe keeps dropping every day and now this travesty. I have read several articles on this Chinese Toxic drywall issue and ....one of the companies making
this said there is NO health hazard ...meanwhile this stuff corrodes metal and even electrical outlets.
[Some] articles were from February and mentioned Dade County/Miami in Florida and other US states, so it has gone from border to border. Can you imagine this, especially if the houses are foreclosed and unsuspecting people think they will get a good deal. Nosebleeds are a common symptom, along with the usual chemical injury symptoms. Those of us with sulfur issues wouldn't be able to walk within yards of this type of building..I haven't heard if it has been used in commercial structures yet. It will be interesting to see how Canada responds to this compared to the US, given that they US has put itself in an "awkward" position with having to continue trade with China.
They are saying it only takes about 3 sheets of this stuff to contaminate a house. Some articles are calling it the "new mold" and "meth" houses because everything in the house needs to be trashed, to say nothing of the health issues.
Class actions abound and won't this be one grave injustice on top of another the rebuilds in Louisiana after Katrina are involved. I also read that they using recycled materials, some of which would be from the huge coal industry in China..I hear they open 2 coal plants in a week, so that would explain the sulfur. It is truly amazing that this **** is even allowed into the country, but it is hardly surprising! One of the builders actually was considered an environmentally safe builder....caveat emptor--let the buyer
beware!!

VANCOUVER - Homeowners from several communities in B.C.'s Lower Mainland have joined the flood of callers to a U.S. consumer group investigating Chinese drywall that has allegedly begun to sicken North Americans.

Thomas Martin, president of America's Watchdog, says that in the past two weeks about a dozen Lower Mainland callers have all reported experiencing the same nose bleeds, breathing problems and allergy-type symptoms that have affected
homeowners across the U.S.

Continued exposure could result in severe health problems, the group says.

"This type of drywall was produced with materials that emit toxic hydrogen sulphide gas and other sulphide gases," says a copy of one home inspection report obtained Canwest News Service on an affected Florida home where Chinese drywall was installed. "These sulphide gases are also alleged to cause serious
health conditions and illnesses, such as shortness of breath, dizziness, headaches, fatigue, insomnia, eye irritations and respiratory difficulties."

"It's scary, it's a nightmare. We think we are looking at the worst case of sick houses in U.S. history," Martin said.

"I'd liken it to the problems you find in a meth house (where an illegal lab has been operating)," he said. "If you have had any experience with a meth house, you know it will have to be bulldozed. Like in a meth house, the emissions permeate everything, the two-by-fours, the trusses, the fabric in your
furniture, your clothes."

The U.S. Consumer Product Safety Commission said last week it was investigating complaints about the Chinese-made drywall.

All houses affected have shown a common symptom - blackened, scorched wiring behind switch plates and wall plugs - and, coupled with homeowner health
symptoms, that's allowed research to proceed, Martin said.

Martin said the group has also fielded calls from worried Canadians who bought property south of the border when the Canadian dollar was high.

The drywall in question was imported from China between 2001 and 2007. According to Martin's research, at least 929,000 square metres were imported through Vancouver between 2001 and 2006, all bound for Canadian destinations.

So far, research shows some appears to have landed on the Prairies, some in Toronto, he said.

One possibility is that the Chinese drywall was made using gypsum that was first used in slurry containing carcinogens to de-sulphur coal.

Chemicals remaining in the wallboard are sufficiently toxic that as few as three sheets of drywall may be enough to contaminate a home to the point it may require bulldozing, Martin says.
