A study by the US Consumer Product Safety Commission has linked Chinese drywall to not only the corrosion of metal and electrical components in US homes and a "rotten egg" odor, but to a whole slew of respiratory problems. Yikes!
When I'm shopping for supplies, the last thing that I want to think about is whether materials will cause health problems, so I always try to buy eco-friendly, chemical-free products. But some materials just don't have a non-toxic replacement, and obviously, these homeowners had no clue their homes would be built with faulty materials.
