[Best Syndication News] A list of drywall manufacturers were released by the US Consumer Product Safety Commission (CPSC) for the high levels of hydrogen sulfide. The CPSC had Lawrence Berkeley National Laboratory (LBNL) test drywall samples for emitting the noxious hydrogen sulfide fumes which has caused metal corrosion and health complaints by homeowners. The corroded metal in the homes have spurred a major class action Chinese drywall lawsuit and have prompted the CPSC to investigate the health claims as well as the property damage caused from the fume emitting gypsum board. The CPSC say that they have noticed a difference especially in Chinese plasterboard samples manufactured in 2005/2006 with the emission of hydrogen sulfide. The CPSC have not come to a conclusion on health complaints received because of the problem Chinese drywall fumes.

Out of all the drywall they tested, they found that the top 10 manufacturers were Chinese Drywall makers. The CPSC said that the Chinese drywall at times had 100 times more emission rate of hydrogen sulfide compared to the non-Chinese drywall samples.
