Chinese Drywall Found to Differ Chemically



Florida is a center of homeowner complaints that Chinese drywall is causing health problems. A housing development in Boynton Beach, Fla., tries to take advantage of that to bolster its sales.

The New York Times - Federal investigators reported Thursday that imported Chinese drywall that homeowners have linked to health problems and odors had higher levels of some chemicals than its domestic counterparts.

The investigators, however, were unable to link the chemicals, sulfur and strontium, to the health problems and smells in thousands of homes built during the recent housing boom, and said further testing was under way to determine any possible connection.

The preliminary findings are part of a larger study by federal agencies, including the Consumer Product Safety Commission and the Environmental Protection Agency, into complaints from nearly 2,000 homeowners that their recently built homes emit odors and cause nosebleeds and respiratory problems. The owners also say their electrical appliances have failed and their wiring has corroded. It has been estimated that more than 60,000 homes could have the imported drywall. Large amounts of Chinese drywall were imported over the last few years when domestic supplies ran short. An estimated seven million sheets made in China were used as a substitute. Most of the complaints come from Florida, Virginia and Louisiana, where the widespread destruction after hurricanes lead to rapid rebuilding of damaged homes.
