Boston - The U.S. Centers for Disease Control and Prevention (CDC) have revealed that poor construction materials are to blame for the high formaldehyde levels in FEMA trailers.
The U.S. government issued nearly 140,000 travel trailers to help people on the Gulf Coast following Hurricane Katrina, as well as Rita.
Currently, over 15,000 families still live in them as of today.
A study carried out by the CDC has found that construction materials, combined with poor ventilation caused the high levels of formaldehyde in the trailers.
There are many health concerns linked to high levels of formaldehyde, including respiratory problems, skin rashes, and other ailments.
