The bulk of these incidents have been reported in Florida and other southern states, likely due to the high levels of heat and humidity in that region. Most of the affected homes were built during the housing boom between 2004 and 2007, especially in the wake of Hurricane Katrina when domestic building materials were in short supply. An estimated 250,000 tons of drywall were imported from China during that time period because it was cheap and plentiful. This material was used in the construction of approximately 100,000 homes in the United States, and many believe this has lead to serious health and property damage.
Although not believed to be life- threatening, exposure to high levels of airborne hydrogen sulfide and other sulfur compounds from contaminated drywall can result in the following physical ailments:
- sore throat;
- sinus irritation;
- dry or burning eyes; and/or
- respiratory infections.
- The house has a strong sulfur smell reminiscent of rotten eggs.
- Exposed copper wiring appears dark and corroded. Silver jewelry and silverware can become similarly corroded and discolored after several months of exposure.
- A manufacturer’s label on the back of the drywall can be used to link it with manufacturers that are known to have used contaminated materials. One way to look for this is to enter the attic and remove some of the insulation.
- Drywall samples can be sent to a lab to be tested for dangerous levels of sulfur. This is the best testing method but also the most expensive.
