Some drywall imported into the U.S. from China between 2003 and 2007 emits, under certain conditions, a corrosive mixture of pollutants into homes after installation. An overview of issues will be presented by the State of Florida and an affected homeowner. The results of research to define the basic chemistry, assess impacts on occupants and materials, and identify effective control strategies will be presented by representatives of federal agencies, the manufacturer and others. The development of assessment and control protocols for field practitioners will also be discussed.
