The CPSC’s Interagency Task Force on Chinese drywall has just issued an interim report. In the report, the CPSC notes that it has found hydrogen sulfide and formaldehyde in the affected drywall. The CPSC believes that the sulfide is causing the reported corrosion and that the combination of sulfide and formaldehyde may account for the claims of sickness. This latter opinion is caveated, however, by the fact that the reported levels of formaldehyde and sulfide are below known irritant levels.
