Contaminated drywall from China, used to build more than 60,000 homes in at least a dozen states, may be emitting toxic levels of chemical pollutants like sulfur into new homes.
More than 500 million pounds of potentially tainted Chinese building materials may have been imported into the United States, particularly to Florida, at the height of the housing boom, according to shipping records reviewed by The Associated Press (AP).
The drywall lets off fumes that smell like rotten eggs and are potent enough to corrode copper pipes and make jewelry and silverware turn black. In fact, one of the telltale signs that a home may contain Chinese drywall is corroded piping and wiring that causes electronics and appliances, including air conditioners, to fail.
Some homeowners have also issued lawsuits alleging the drywall has caused health effects ranging from headaches and sore throats to dizziness and respiratory illness.
“This is a traumatic problem of extraordinary proportions,” said U.S. Rep. Robert Wexler in an AP article.
Wexler has introduced a bill calling for a temporary ban on Chinese-made building imports until their chemical makeup is investigated further. Florida has been particularly hard-hit with Chinese drywall problems.
