Chinese Drywall

Watch out for some Chinese manufactured drywall.  I first spotted this on the local news.  It appears to have moved to a congressional hearing.  Certain home builders evidently looked to save a buck by trying out chinese drywall.  Evidently certain kinds imported from China contained small amounts of sulfer.  From Popular Mechanics here:

...some Chinese drywall contains strontium sulfide, a material absent from most samples manufactured in the United States. The EPA tests for this material are still pending, but scientists suspect that this compound, which releases sulfurous gases, could be the cause of homeowner complaints that range from nose­bleeds and respiratory ailments to black coatings tarnishing shower fixtures and corroding air-conditioner coils.
