PARKLAND, Fla. (AP) -- At the height of the U.S. housing boom, when building materials were in short supply, American construction companies used millions of pounds of Chinese-made drywall because it was abundant and cheap.
Now that decision is haunting hundreds of homeowners and apartment dwellers who are concerned that the wallboard gives off fumes that can corrode copper pipes, blacken jewelry and silverware, and possibly sicken people.
Shipping records reviewed by The Associated Press indicate that imports of potentially tainted Chinese building materials exceeded 500 million pounds during a four-year period of soaring home prices. The drywall may have been used in more than 100,000 homes, according to some estimates, including houses rebuilt after Hurricane Katrina.
"This is a traumatic problem of extraordinary proportions," said U.S. Rep. Robert Wexler, a Florida Democrat who introduced a bill in the House calling for a temporary ban on the Chinese-made imports until more is known about their chemical makeup. Similar legislation has been proposed in the Senate.
The drywall apparently causes a chemical reaction that gives off a rotten-egg stench, which grows worse with heat and humidity.
Researchers do not know yet what causes the reaction, but possible culprits include fumigants sprayed on the drywall and material inside it. The Chinese drywall is also made with a coal byproduct called fly ash that is less refined than the form used by U.S. drywall makers.
In 2006, enough wallboard was imported from China to build some 34,000 homes of roughly 2,000 square feet each, according to AP's analysis of the shipping records and estimates supplied by the nationwide drywall supplier United States Gypsum.
So far, the problem appears to be concentrated in the Southeast, which blossomed with new construction during the housing boom and where the damp climate appears to cause the gypsum in the building material to degrade more quickly. In Florida alone, more than 35,000 homes may contain the product, experts said.
In Louisiana, the state health department has received complaints from at least 350 people in just a few weeks. Many of the affected homeowners rebuilt after Hurricane Katrina only to face the prospect of tearing down their houses and rebuilding again.
Outside the South, it's harder to pinpoint the number of affected homes. And in drier climates such as California and Nevada, it may be years before homeowners begin to see -- and smell -- what may be lurking inside their walls.
A Florida Department of Health analysis found the Chinese drywall emits "volatile sulfur compounds," and contains traces of strontium sulfide, which can produce the rotten-egg odor and reacts with air to corrode metals and wires.
"If a shiny copper coil can turn absolutely black within a matter of months, it certainly can't be good for human beings," Krulik said.
