High levels of formaldehyde found in trailers used by Hurricane Katrina victims has brought discussion about the chemical’s health hazards to the forefront. A study released recently by the National Cancer Institute confirms a link between formaldehyde and cancers such as leukemia and other cancers. The study shows that workers exposed to the most formaldehyde had a 37 percent greater risk of death from blood and lymphatic cancers, and a 78 percent greater risk of leukemia than the others. Many have formaldehyde in their homes in the form of the glues in pressed wood. One solution to reduce exposure is to seal the formaldehyde in by using a special safecoat” sealant designed for this purpose.
