Tens of thousands of people lost homes in Katrina in 2005 and many have been living for about two years in trailers bought by the government for temporary housing. Some residents have attributed health problems to formaldehyde exposure.
The CDC conducted indoor air-quality tests for formaldehyde between Dec. 21 and Jan. 23, 2008 on a random sample of 519 travel trailers and mobile homes in Mississippi and Louisiana.
Formaldehyde is a chemical used widely in the manufacture of building materials. It also is used in embalming fluid. It can irritate the skin, eyes, nose and throat, and high levels of exposure may cause some types of cancers.
