It appears that a specific kind of drywall is causing corrosion of electrical wiring and pipes and has been recalled in the U.S. Many web links indicate that this drywall comes from China.
The U.S. imported a large quantity of this product between 2005 and 2007. The primary States reporting problems appear to be in the south. Many insurance companies are refusing to pay out due to these problems. The substances causing erosion appear to be Hydrogen Sulfide and Formaldehyde. The typical climate of the affected homes doesn't appear to be working well with this type of drywall. CNN
So, if it corrodes metal pipes and wiring, what is it doing to people?
