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.
