The defective Chinese drywall debacle has been making news for months now, with homeowners plagued by sulfur fumes that smell like ??rotten eggs?? and cause air conditioning coils to corrode. Residents complain of sinus and respiratory ailments, eye and skin irritation, persistent runny or bloody noses, headaches, and asthma. Some situations were so severe that residents had to vacate their homes. In some cases, victims have been harassed by builders into signing unfair, one-side remediation agreements.

It seems that the gypsum in drywall, which typically comes from mines, has recently come from a chemical process involving lime or limestone and gas from coal-fired power plants. Contaminants and sulfur found in power plant smokestacks are supposed to be removed in the process. Failure of proper removal is the cause of foul odors, respiratory complaints, and corrosion, according to some Chinese experts in building supplies. Others say phosphogypsum (calcium sulfate), a radioactive phosphorus substance, is to blame. Banned for use in U.S. construction in 1989, the EPA says prolonged exposure to this radium-contained element can lead to a higher risk of lung cancer.

The issues surrounding defective Chinese drywall are confusing and worrisome. Here is a good blog that has been providing emerging and valuable information on the problems: www.chinese-drywall-answers.com
