"Chinese drywall" refers to an environmental health issue involving defective drywall manufactured in China, imported to the United States and used in residential construction between 2001 and 2009 – affecting "an estimated 100,000 homes in more than 20 states". In samples of contaminated drywall, laboratory tests will detect off-gassing of volatile chemicals and sulfurous gases — including carbon disulfide, carbonyl sulfide, and hydrogen sulfide.
