WEST PALM BEACH, Fla. (AP) -- The federal government says it has found a "strong association" between imported Chinese drywall and corrosion of pipes and wires.
The conclusion by the Consumer Product Safety Commission supports complaints by thousands of homeowners over the last year.
The CPSC also says it has found a "possible" link between health problems reported by homeowners and hydrogen sulfide gas emitted from the wallboard when coupled with formaldehyde, which is commonly found in new houses.
The agency has spent $3.5 million on the studies, and has received more than 2,000 homeowner complaints from 32 states, Washington, D.C., and Puerto Rico. It's one of its largest consumer product investigations in U.S. history.
The potential health effects and long-term implications of the corrosion are being studied by the CPSC along with the Environmental Protection Agency and the Centers for Disease Control and Prevention.
