Notice of the names of the drywall manufacturers whose drywall emitted high levels of hydrogen sulfide in testing conducted for the agency by Lawrence Berkeley National Laboratory (LBNL). There is a strong association between hydrogen sulfide and metal corrosion. Of the samples tested, the top ten reactive sulfur-emitting drywall samples were all produced in China. Some of the Chinese drywall had emission rates of hydrogen sulfide 100 times greater than non-Chinese drywall samples.
