The interagency task force on Chinese drywall is releasing today the initial results of several studies that begin to assemble pieces in the overall Chinese drywall puzzle. The investigation continues and
additional reports will be released in November.

In sum, the three studies released today are:

• Elemental and Chemical Testing: The study of the elemental and chemical composition of 17 drywall samples shows higher concentrations of elemental sulfur and strontium in Chinese drywall than in non-Chinese drywall.
• Chamber Studies: Preliminary results of ongoing testing to detect gases emitted from drywall
  in laboratory chambers show higher emissions of total volatile sulfur gases from Chinese than
  from non-Chinese drywall.
• Indoor Air Studies: Indoor air testing of 10 homes in Florida and Louisiana was conducted to
  identify and measure contaminants and to inform a drywall home indoor air testing protocol.
  This data from a small sample of homes, allows preliminary observations of certain chemicals in
  the indoor air. The tests did not detect the presence or found only very limited or occasional
  indications of sulfur compounds of particular interest – hydrogen sulfide, carbon disulfide, and
  carbonyl sulfide. Concentrations of two known irritant compounds, acetaldehyde and
  formaldehyde, were detected in both homes with and without Chinese drywall, and at
  concentrations that could exacerbate conditions such as asthma in sensitive populations. The
  levels of formaldehyde were not unusual for new homes, however, and were higher when the
  homes were not air conditioned.
