Formaldehyde fumes found in temporary shelters for Katrina victims

One might wonder why, in the richest nation on earth, people displaced after Hurricane Katrina (which struck Louisiana and Mississippi) are still living in temporary trailer shelters two years later. In any case, the CDC has found high levels of formaldehyde fumes in those trailers, and sees an immediate need to re-evacuate the residents. Please pray for their safety. The Associated Press has a report.

An excerpt:

The CDC, working with FEMA, hired a contractor. The firm — Bureau Veritas North America — tested air samples from 358 travel trailers, 82 park model and 79 mobile homes.

Analysis of the samples, taken from Dec. 21 through Jan. 23, came back last week, McGeehin said.

They found average levels of 77 parts formaldehyde per billion parts of air, significantly higher than the 10 to 17 parts per billion concentration seen in newer homes. Levels were as high as 590 parts per billion.

The highest concentrations were in travel trailers, which are smaller and more poorly ventilated, McGeehin said.

Indoor air temperature was a significant factor in raising formaldehyde levels, independent of trailer make or model, CDC officials said. McGeehin said that's why the CDC would like residents out before summer.

A broader-based children's health study is also in the works, McGeehin said.

Last week, congressional Democrats accused FEMA of manipulating scientific research in order to play down the danger posed by formaldehyde in the trailers.

In its initial round of testing, FEMA took samples from unoccupied trailers that had been aired out for days and compared them with federal standards for short-term exposure, according to the lawmakers.

Legislators also said the CDC ignored research from — and then demoted — one of its own experts, who concluded any level of exposure to formaldehyde may pose a cancer risk. A CDC spokesman has denied the allegations.
