They’re the same Chinese who produced the hazardous drywall that was exported to the U.S. from 2001-2009. It was found to be defective, containing high levels 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. This drywall was imported, and used in 20 U.S. States and created an environmental and health hazard. It was used mostly in Florida, Louisiana, Mississippi, and Alabama after Hurricane Katrina in 2005.
