From China Daily:

An investigation that spans the globe into the cause of widespread illness in the United States allegedly from contaminated drywall imported from China continues, but initial clues to answers will be revealed later this week. Safety officials from both China and the US are working together in the probe and the visiting US Consumer Products Safety Commission (CPSC) will release results of initial testing of both Chinese- and US-made drywall…

Thousands of US homeowners complained last year that contaminated drywall from China sickened them or damaged their houses. The allegedly problematic drywall, also known as wallboard or gypsum board, was imported between 2004 and 2008 when the housing industry was booming and supplies were tight in the US…The drywall is believed to cause a chemical reaction, releasing fumes that reek like rotten eggs. US homeowners, mostly in the southeastern regions, blamed the drywall for health woes, such as itchy eyes and skin, difficulty breathing, persistent coughing and bloody noses as well as corrosion of electrical wiring and home appliances.

Tests of Chinese-made drywall by the US Environmental Protection Agency (EPA) have found sulfur and two organic compounds associated with acrylic paint – compounds not found in samples of US-made drywall. The EPA report did not draw any conclusions about health risks or whether the boards could be damaging wires in homes.
