Be careful, there has been a recent outbreak in the Gulf Coast area with homeowners complaining about Odors in their homes. The federal and state authorities have found a radioactive substance called "phosphogypsum" in drywall that was imported from China.
The reason for drywall imported from China has been due to the hurricane destruction these pasts years since 2006 and the U.S. Gypsums companies being unable to keep up with demand.
Among the list of risks that this substances causes are lung cancer, corrosion of metallic substances and nose bleeds. However, there is not conclusive proof that this product in fact causes cancer there are a lot of concerns.
This substance was banned by the EPA back in 1989, but is only monitored in locally produced products. There isn't really any plan in place that monitors a variety of foreign imports. As I have found on a few of my projects which materials were sourced from Chinese imports, the quality of their products typically do not stand up to locally produced brands (doors, windows, wood products, fiber-glass based products) and stress that all consumers begin to ask questions about the types of materials that you purchase.
Everyone must remember that your money is a "vote" for everything you purchase, and you should not enter lightly into that when it comes to your living environments. As a professional it is my responsibility to pay attention to the types and quality of products that I use on my projects. I will not plug any one provider over another, but I want to make sure that people are very careful and am constantly in search of new opportunities to find sustainable solutions for your living environments. Always ask "what am I getting" whenever you engage into purchasing the next material for your home, because your decisions do have a direct impact on yours and your families health.
