Reid said his research indicates at least some drywall imported from China during the homebuilding boom years of 2004 and 2005 was made with waste materials from scrubbers on coal-fired power plants.
Those materials can leak into the air as gases combine with the moisture on an air conditioning coil to create sulfuric acid, which appears to be dissolving solder joints and copper tubing – creating leaks, blackening the coils and even causing the system to fail, Reid said.
