The housing boom in the early-mid part of the decade has been noted as the beginning of this problem. Normally, drywall is bought from domestic producers, but the boom caused shortages, so some home builders, particularly in Florida, purchased drywall shipped in from China. Only a few years later, in 2009, there appears to be something rotten in the State of Florida.
Home owners have reported everything from sore throats to unexplained personality changes in their pets. Everything in between includes: respiratory problems, headaches and nosebleeds, pet ill health, nasty sulfur odors with no apparent source and a general feeling of malaise. Homeowners with young children or those who are expecting are refusing to return to the houses they bought, for fear it might damage their children's health.
Despite the Florida Department of Health's assurance that there is “no immediate health threat”, homeowners remain unconvinced about the “un-immediate” health threats lurking in their homes. The experience of some homeowners, who felt ‘miraculously' better when traveling away from their residences for an extended period of time, has convinced many that the problem lies within the homes and could constitute a threat to their continued health and safety.
One theory is that the drywall isn't gypsum at all, but a less appetizing mix of waste from power plant scrubbers. This would explain the high content of sulfur-based gases that are being emitted from some of the drywall examined, and for the rapid deterioration of electrical connections and household appliances. Some gases named as being present in tested board include hydrogen sulfide, sulfur dioxide, carbon disulfide, and carbonyl sulfide. Fumes from hydrogen sulfide can cause severe respiratory distress and death.
Sulphur-based gases produce something else when they come into contact with moisture: sulfuric acid, which eats away at many materials like a beaver in an aspen grove. This can explain while many people have gone through three or more appliances in five years when the appliance itself should be lasting for ten or twenty. Air conditioners, TVs and other common household appliances are being affected as well as medical equipment. While not having a TV working can be an annoyance, not having one's dialysis machine or heart monitor functioning can be serious or even fatal.
The drywall problem, combined with other issues relating to toxic materials found in other items produced in China is leading to a demand for tighter regulations and inspections. Also, for provisions that address the needs of homeowners faced with homelessness because they dare not re-enter their homes due to health concerns. Some home builders are addressing this by relocating families while they conduct tests, but many homeowners are fighting with their home builders who say that there is no appreciable health risk.
The “Chinese drywall” problem is something we are likely to hear more about in the very near future. For now, it behooves those who are purchasing new homes to find out where their drywall comes from and avoid anything with a “Made in China” label.
