CPSC study confirms homeowner's worst fears about Chinese drywall

A study of 51 homes released this week by the Consumer Product Safety Commission (CPSC) found a strong association between homes with Chinese drywall and levels corrosive hydrogen sulfide, which gives off a smell similar to rotten eggs.

It was the largest investigation ever taken on by the CPSC, costing $3.5 million and involving 15% of the staff, according to the CPSC.
