Bacteria could be drywall culprit

Scientists looking at the unpleasant effects of tainted Chinese drywall are trying to determine if the problem is caused by a chemical reaction or bacteria. Some labs say the building material has significant amounts of sulfate-reducing bacteria, which would account for the stench that’s been linked to corroded metal fixtures and associated with health problems including rashes and nosebleeds. Dr. David Krause, a toxicologist with the Florida Department of Health, said the bacteria theory needs further testing, and that even if there is a high level of bacteria in the drywall, no link has been established to the sulfur gas emissions.
