Florida: Drywall has material that can emit corrosive gas

Strontium sulfide, a material that can emit corrosive gases in moist air, was found at trace levels in testing of Chinese-made drywall, the Florida Department of Health said. The drywall samples gave off a sulfurous odor when heated, and in at least one case, sulfide gases corroded copper coils in an air conditioner of a Florida home containing Chinese drywall, said the department, which commissioned the study.
