"Chinese drywall" refers to an environmental health issue involving defective drywall manufactured in China. Laboratory tests of samples for volatile chemicals have identified emissions of the sulfurous gases carbon disulfide, carbonyl sulfide, and hydrogen sulfide. These emissions, which have the odor of rotten eggs, worsen as temperature and humidity rise and cause copper surfaces to turn black and powdery, a chemical process indicative of reaction with hydrogen sulfide.
Copper pipes, wiring, and air conditioner coils are affected, as well as silver jewelry. Homeowners have reported a variety of symptoms, including respiratory problems such as asthma attacks, chronic coughing and difficulty breathing, as well as chronic headaches and sinus issues.
This drywall was used in a very limited amount of construction in our area. This was done mostly from 2004 to 2007. By now, most of the homes affected have had the drywall removed and replaced.
In Florida we use a "seller's disclosure" which requires the seller to alert the buyer to many things they know about the home, including whether it does or did contain "Chinese drywall". When purchasing a home I recommend that we use an inspector with experience in identifying "Chinese drywall". This provides further protection against buying a home with it.
